What Is the Quality of Surgical Care for Patients with Hip Fractures at Critical Access Hospitals?

BACKGROUND: Critical access hospitals (CAHs) play an important role in providing access to care for many patients in rural communities. Prior studies have shown that these facilities are able to provide timely and quality care for patients who undergo various elective and emergency general surgical procedures. However, little is known about the quality and reimbursement of surgical care for patients undergoing surgery for hip fractures at CAHs compared with non-CAH facilities. QUESTIONS/PURPOSES: Are there any differences in 90-day complications, readmissions, mortality, and Medicare payments between patients undergoing surgery for hip fractures at CAHs and those undergoing surgery at non-CAHs? METHODS: The 2005 to 2014 Medicare 100% Standard Analytical Files were queried using ICD-9 procedure codes to identify Medicare-eligible beneficiaries undergoing open reduction and internal fixation (79.15, 79.35, and 78.55), hemiarthroplasty (81.52), and THA (81.51) for isolated closed hip fractures. This database was selected because the claims capture inpatient diagnoses, procedures, charged amounts and paid claims, as well as hospital-level information of the care, of Medicare patients across the nation. Patients with concurrent fixation of an upper extremity, lower extremity, and/or polytrauma were excluded from the study to ensure an isolated cohort of hip fractures was captured. The study cohort was divided into two groups based on where the surgery took place: CAHs and non-CAHs. A 1:1 propensity score match, adjusting for baseline demographics (age, gender, Census Bureau-designated region, and Elixhauser comorbidity index), clinical characteristics (fixation type and time to surgery), and hospital characteristics (whether the hospital was located in a rural ZIP code, the average annual procedure volume of the operating facility, hospital bed size, hospital ownership and teaching status), was used to control for the presence of baseline differences in patients presenting at CAHs and those presenting at non-CAHs. A total of 1,467,482 patients with hip fractures were included, 29,058 of whom underwent surgery in a CAH. After propensity score matching, each cohort (CAH and non-CAH) contained 29,058 patients. Multivariate logistic regression analyses were used to assess for differences in 90-day complications, readmissions, and mortality between the two matched cohorts. As funding policies of CAHs are regulated by Medicare, an evaluation of costs-of-care (by using Medicare payments as a proxy) was conducted. Generalized linear regression modeling was used to assess the 90-day Medicare payments among patients undergoing surgery in a CAH, while controlling for differences in baseline demographics and clinical characteristics. RESULTS: Patients undergoing surgery for hip fractures were less likely to experience many serious complications at a critical access hospital (CAH) than at a non-CAH. In particular, after controlling for patient demographics, hospital-level factors and procedural characteristics, patients treated at a CAH were less likely to experience: myocardial infarction (3% (916 of 29,058) versus 4% (1126 of 29,058); OR 0.80 [95% CI 0.74 to 0.88]; p < 0.001), sepsis (3% (765 of 29,058) versus 4% (1084 of 29,058); OR 0.69 [95% CI 0.63 to 0.78]; p < 0.001), acute renal failure (6% (1605 of 29,058) versus 8% (2353 of 29,058); OR 0.65 [95% CI 0.61 to 0.69]; p < 0.001), and Clostridium difficile infections (1% (367 of 29,058) versus 2% (473 of 29,058); OR 0.77 [95% CI 0.67 to 0.88]; p < 0.001) than undergoing surgery in a non-CAH. CAHs also had lower rates of all-cause 90-day readmissions (18% (5133 of 29,058) versus 20% (5931 of 29,058); OR 0.83 [95% CI 0.79 to 0.86]; p < 0.001) and 90-day mortality (4% (1273 of 29,058) versus 5% (1437 of 29,058); OR 0.88 [95% CI 0.82 to 0.95]; p = 0.001) than non-CAHs. Further, CAHs also had risk-adjusted lower 90-day Medicare payments than non-CAHs (USD 800, standard error 89; p < 0.001). CONCLUSION: Patients who received hip fracture surgical care at CAHs had a lower risk of major medical and surgical complications than those who had surgery at non-CAHs, even though Medicare reimbursements were lower as well. Although there may be some degree of patient selection at CAHs, these facilities appear to provide high-value care to rural communities. These findings provide evidence for policymakers evaluating the impact of the CAH program and allocating funding resources, as well as for community members seeking emergent care at local CAH facilities. LEVEL OF EVIDENCE: Level III, therapeutic study.

Spanish National Hip Fracture Registry (RNFC): analysis of its first annual report and international comparison with other established registries.

Hip fracture registries have helped improve quality of care and reduce variability, and several audits exist worldwide. The results of the Spanish National Hip Fracture Registry are presented and compared with 13 other national registries, highlighting similarities and differences to define areas of improvement, particularly surgical delay and early mobilization. INTRODUCTION: Hip fracture audits have been useful for monitoring current practice and defining areas in need of improvement. Most established registries are from Northern Europe. We present the results from the first annual report of the Spanish Hip Fracture Registry (RNFC) and compare them with other publically available audit reports. METHOD: Comparison of the results from Spain with the most recent reports from another ten established hip fracture registries highlights the differences in audit characteristics, casemix, management, and outcomes. RESULTS: Of the patients treated in 54 hospitals, 7.208 were included in the registry between January and October 2017. Compared with other registries, the RNFC included patients ≥ 75 years old; in general, they were older, more likely to be female, had a worse prefracture ambulation status, and were more likely to have extracapsular fractures. A larger proportion was treated with intramedullary nails than in other countries, and spinal anesthesia was most commonly used. With a mean of 75.7 h, Spain had by far the longest surgical delay, and the lowest proportion of patients mobilized on the first postoperative day (58.5%). Consequently, development of pressure ulcers was high, but length of stay, mortality, and discharge to home remained in the range of other audits. CONCLUSIONS: National hip fracture registries have proved effective in changing clinical practice and our understanding of patients with this condition. Such registries tend to be based on an internationally recognized common dataset which would make comparisons between national registries possible, but variations such as age inclusion criteria and follow-up are becoming evident across the world. This variation should be avoided if we are to maximize the comparability of registry results and help different countries learn from each other's practice. The results reported in the Spanish RNFC, compared with those of other countries, highlight the differences between countries and detect areas of improvement, particularly surgical delay and early mobilization.

Ossification of the Proximal and Middle Phalangeal Condyles: Radiographic Aid in Phalangeal Neck Fracture Reduction.

BACKGROUND: Phalangeal neck fractures are commonly dorsally displaced and angulated. Surgical treatment is often necessary to restore the retrocondylar recess. The purpose of this study was to determine whether radiographic landmarks can serve as a reference tool for assessing phalangeal neck fracture alignment based on age and sex. METHODS: In total, 1061 lateral finger radiographs that were interpreted as "normal" by pediatric radiologists in children aged 1 to 18 years were retrospectively reviewed. The proximal and middle phalanges of each digit had a line drawn along the volar cortex [termed the volar phalangeal line (VPL)] and a second perpendicular line was drawn at the level of the phalangeal condyle. A ratio of the anterior to posterior aspects of the phalangeal condyle was determined at the intersection of these lines. Sex of the patients was noted to determine whether it influenced the temporal course of ossification. A linear regression model was utilized to determine the annual coefficient of growth for the phalangeal condyles. RESULTS: There is a temporal course of ossification of the proximal and middle phalangeal condyles. As children increase in age, the VPL will intersect the phalangeal condyle more dorsally due to the eccentric ossification. In children above 9 years of age, the VPL will reliably intersect the middle one third of the phalangeal condyle. No clinically significant difference exists between the ratios of the proximal and middle phalanges. Sex was not associated with a difference in growth. The greatest growth increase was observed in the 8 to 9-year-old interval. CONCLUSIONS: The phalangeal condyles ossify in an eccentric manner and the VPL will intersect the phalangeal condyle more dorsally with increasing age. The VPL and knowledge of where it should intersect the phalangeal condyle can be used as a reference guide for evaluating the reduction of proximal and middle phalangeal neck fractures in children. LEVEL OF EVIDENCE: Level III.

Standards for external fixation application: national survey under the auspices of the German Trauma Society.

INTRODUCTION: External fixation is widely accepted as a provisional or sometimes definitive treatment for long-bone fractures. Indications include but are not limited to damage control surgery in poly-traumatized patients as well as provisional bridging to definite treatment with soft tissue at risk. As little is known about surgeon's habits in applying this treatment strategy, we performed a national survey. METHODS: We utilized the member database of the German Trauma Society (DGU). The questionnaire encompassed 15 questions that addresses topics including participants' position, experience, workplace, and questions regarding specifics of external fixation application in different anatomical regions. Furthermore, we compared differences between trauma centre levels and surgeon-related factors. RESULTS: The participants predominantly worked in level 1 trauma centres (42.7%) and were employed as attendings (54.7%). There was widespread consensus for planning and intra-operative radiographical control of external fixation. Surgeons appointed at a level I trauma centre preferred significantly more often supra-acetabular pin placement in external fixation of the pelvis rather than the utilization of iliac pins (75.8%, p = 0.0001). Moreover, they were more likely to favor a mini-open approach to insert humeral pins (42.4%, p = 0.003). Overall, blunt dissection and mini-open approaches seemed equally popular (38.2 and 34.1%). Department chairmen indicated more often than their colleagues to follow written pin-care protocols for minimization of infection (16.7%, p = 0.003). CONCLUSION: Despite the fact that external fixation usage is widespread and well established among trauma surgeons in Germany, there are substantial differences in the method of application.

Temporary Fixation of Reduction with Fabric Adhesive Bandage in the Surgical Treatment of Pediatric Supracondylar Humerus Fractures.

Background and objectives: Supracondylar humerus fractures are common in children andcan be surgically treated. However, the general surgical procedures involving reduction andfixation might lead to reduction loss, failure to direct the Kirschner (K)-wire toward the desiredposition, prolonged surgery, or chondral damage. This study aimed to show that temporaryfixation of closed reduction with a fabric adhesive bandage in pediatric supracondylar humerusfractures could maintain reduction so that surgical treatment can be easily performed by a singlephysician. Materials and Methods: Forty-six patients with Gartland type 3 supracondylar humerusfractures who underwent surgical treatment between May 2017 and June 2018 were retrospectivelyevaluated. Fluoroscopy-guided reduction and fixation were performed from the distal third of theforearm to the proximal third of the humerus using a fabric adhesive bandage. Two crossed pinswere applied on the fracture line by first inserting a lateral-entry K-wire and then inserting anotherK-wire close to the anterior aspect of the medial epicondyle and diverging from the ulnar nervetunnel. A tourniquet was not applied in any patient and no patients required open reduction.Results: The study included 32 boys (69.6%) and 14 girls (30.4%) (mean age, 7.1; range, 2-16 years).The mean hospital stay and follow-up duration were 4.3 ± 3.9 days and 48.1 ± 14.3 weeks,respectively. Heterotopic ossification was detected in one patient, and ulnar nerve neuropraxia wasdetected in another patient. Functional (according to Flynn criteria) and cosmetic outcomes wereexcellent in 95.6%, moderate in 2.2%, and poor in 2.2% of patients. The mean duration of fixation ofthe closed reduction with a fabric adhesive bandage was 8.1 ± 3.9 min, and the mean duration ofpinning was 7.9 ± 1.4 min. Conclusions: Temporary preoperative fixation of supracondylar humerusfractures that require surgical treatment with a fabric adhesive bandage may be significantlyconvenient in practice.

A web-based survey to identify current practice in skeletal pin site management.

Infections associated with percutaneous pins and wires are common complications which can have a significant impact on patient outcomes. A survey was undertaken to identify current practice and gain insight into variations of clinical practice. Invitations were sent by email to complete an electronic questionnaire using SurveyMonkey. The survey was left open for 100 days. The single largest group of respondents (37.4%, n = 120) cleansed pin sites daily, with significant differences identified between medical and nursing professions (P = 0.02), and country of practice (P < 0.001). Significant differences were also identified in the use of different cleansing solutions between medical and nursing professions (P < 0.001) and country (P < 0.001). The majority group preferences were saline 30% (n = 96) and alcoholic chlorhexidine 29.6% (n = 95). Pin site crusts were routinely removed by 57.9% (n = 186). Pin sites were left exposed by 50.3% (n = 160). Dry gauze was identified as the most common dressing used to dress pin sites, however, substantial variation was identified in the types of dressings used. Compression was not routinely applied to pin sites by 51.6% (n = 165). There remains considerable diversity of practice when caring for pin sites. Further research is required to identify the most effective methods in preventing pin site infection.

Improving hip fracture outcomes with integrated orthogeriatric care: a comparison between two accepted orthogeriatric models.

Background: our orthopaedic trauma unit serves a large elderly population, admitting 400-500 hip fractures annually. A higher than expected mortality was detected amongst these patients, prompting a change in the hip fracture pathway. The aim of this study was to assess the impact of a change in orthogeriatric provision on hip fracture outcomes and care quality indicators. Patients and Methods: the hip fracture pathway was changed from a geriatric consultation service to a completely integrated service on a dedicated orthogeriatric ward. A total of 1,894 consecutive patients with hip fractures treated in the 2 years before and after this intervention were analysed. Results: despite an increase in case complexity, the intervention resulted in a significant reduction in mean length of stay from 27.5 to 21 days (P < 0.001), a significant reduction in mean time to surgery from 41.8 to 27.2 h (P < 0.001) and a significant 22% reduction in 30-day mortality (13.2-10.3%, P = 0.04). After controlling for the effects of age, gender, American Society of Anesthesiology (ASA) Grade and abbreviated mental test score (AMTS), the effect of integrating orthogeriatric services into the hip fracture pathway significantly reduced the risk of mortality (odds ratio 0.68, P = 0.03). Conclusions: changing our hip fracture service from a geriatric consultation model of care to an integrated orthogeriatric model significantly improved mortality and performance indicators. This is the first study to directly compare two accepted models of orthogeriatric care in the same hospital.

Is additional balloon Kyphoplasty safe and effective for acute thoracolumbar burst fracture?

BACKGROUND: Burst fracture is a common thoracolumbar injury that is treated using posterior pedicle instrumentation and fusion combined with transpedicular intracorporeal grafting after reduction. In this study, we compared the outcome of these two techniques by using radiologic imaging and functional outcome. METHODS: Sixty-one patients with acute thoracolumbar burst fracture were operated with kyphoplasty (n = 31) or vertebroplasty (n = 30) and retrospectively reviewed in our institution between 2011 and 2014. All 61 patients underwent surgery within 5 days after admission to the hospital and then followed-up for 12 to 24 months after surgery. RESULTS: Significant improvement was found in the anterior vertebral height (92 ± 8.9% in the kyphoplasty group, 85.6 ± 7.2% in the vertebroplasty group, p < 0.01) at 1 month post-operatively and (89 ± 7.9% in the kyphoplasty group, 78 ± 6.9% in the vertebroplasty group, p < 0.01) at the 24-month follow-up. Significant improvement was also observed in the kyphotic angle (1.2 ± 0.5° in the kyphoplasty group, 10.5 ± 1.2° in the vertebroplasty group, p < 0.01) at 1 month post-operatively and (5.4 ± 1.2° in the kyphoplasty group, 11.5 ± 8.5° in the vertebroplasty group, p < 0.01) at the 24-month follow-up. Both operations led to significant improvement of the patients' pain and the Oswestry disability index (p < 0.01). Cement leakage was noted in 29% of patients after kyphoplasty and 77% of patients after vertebroplasty (p < 0.01). Only one implant failure (3.3%), which required further surgical intervention, was reported in the vertebroplasty group. CONCLUSIONS: Reduction with additional balloon at the fractured site is better than indirect reduction only by posterior instrumentation. The better reduction of kyphotic angle and the lower cement leakage rate in the kyphoplasty group indicate that additional balloon kyphoplasty is safe and effective for acute thoracolumbar burst fracture.

Can improved quality of care explain the success of orthogeriatric units? A population-based cohort study.

BACKGROUND: admission to orthogeriatric units improves clinical outcomes for patients with hip fracture; however, little is known about the underlying mechanisms. OBJECTIVE: to compare quality of in-hospital care, 30-day mortality, time to surgery (TTS) and length of hospital stay (LOS) among patients with hip fracture admitted to orthogeriatric and ordinary orthopaedic units, respectively. DESIGN: population-based cohort study. MEASURES: using prospectively collected data from the Danish Multidisciplinary Hip Fracture Registry, we identified 11,461 patients aged ≥65 years admitted with a hip fracture between 1 March 2010 and 30 November 2011. The patients were divided into two groups: (i) those treated at an orthogeriatric unit, where the geriatrician is an integrated part of the multidisciplinary team, and (ii) those treated at an ordinary orthopaedic unit, where geriatric or medical consultant service are available on request. Outcome measures were the quality of care as reflected by six process performance measures, 30-day mortality, the TTS and the LOS. Data were analysed using log-binomial, linear and logistic regression controlling for potential confounders. RESULTS: admittance to orthogeriatric units was associated with a higher chance for fulfilling five out of six process performance measures. Patients who were admitted to an orthogeriatric unit experienced a lower 30-day mortality (adjusted odds ratio (aOR) 0.69; 95% CI 0.54-0.88), whereas the LOS (adjusted relative time (aRT) of 1.18; 95% CI 0.92-1.52) and the TTS (aRT 1.06; 95% CI 0.89-1.26) were similar. CONCLUSIONS: admittance to an orthogeriatric unit was associated with improved quality of care and lower 30-day mortality among patients with hip fracture.

Objective Structured Assessments of Technical Skills (OSATS) Does Not Assess the Quality of the Surgical Result Effectively.

BACKGROUND: Performance assessment in skills training is ideally based on objective, reliable, and clinically relevant indicators of success. The Objective Structured Assessment of Technical Skill (OSATS) is a reliable and valid tool that has been increasingly used in orthopaedic skills training. It uses a global rating approach to structure expert evaluation of technical skills with the experts working from a list of operative competencies that are each rated on a 5-point Likert scale anchored by behavioral descriptors. Given the observational nature of its scoring, the OSATS might not effectively assess the quality of surgical results. QUESTIONS/PURPOSES: (1) Does OSATS scoring in an intraarticular fracture reduction training exercise correlate with the quality of the reduction? (2) Does OSATS scoring in a cadaveric extraarticular fracture fixation exercise correlate with the mechanical integrity of the fixation? METHODS: Orthopaedic residents at the University of Iowa (six postgraduate year [PGY]-1s) and at the University of Minnesota (seven PGY-1s and eight PGY-2s) undertook a skills training exercise that involved reducing a simulated intraarticular fracture under fluoroscopic guidance. Iowa residents participated three times during 1 month, and Minnesota residents participated twice with 1 month between their two sessions. A fellowship-trained orthopaedic traumatologist rated each performance using a modified OSATS scoring scheme. The quality of the articular reduction obtained was then directly measured. Regression analysis was performed between OSATS scores and two metrics of articular reduction quality: articular surface deviation and estimated contact stress. Another skills training exercise involved fixing a simulated distal radius fracture in a cadaveric specimen. Thirty residents, distributed across four PGY classes (PGY-2 and PGY-3, n = 8 each; PGY-4 and PGY-5, n = 7 each), simultaneously completed the exercise at individual stations. One of three faculty hand surgeons independently scored each performance using a validated OSATS scoring system. The mechanical integrity of each fixation construct was then assessed in a materials testing machine. Regression analysis was performed between OSATS scores and two metrics of fixation integrity: stiffness and failure load. RESULTS: In the intraarticular fracture model, OSATS scores did not correlate with articular reduction quality (maximum surface deviations: R = 0.17, p = 0.25; maximum contact stress: R = 0.22, p = 0.13). Similarly in the cadaveric extraarticular fracture model, OSATS scores did not correlate with the integrity of the mechanical fixation (stiffness: R = 0.10, p = 0.60; failure load: R = 0.30, p = 0.10). CONCLUSIONS: OSATS scoring methods do not effectively assess the quality of the surgical result. Efforts must be made to incorporate assessment metrics that reflect the quality of the surgical result. CLINICAL RELEVANCE: New objective, reliable, and clinically relevant measures of the quality of the surgical result obtained by a trainee are urgently needed. For intraarticular fracture reduction and extraarticular fracture fixation, direct physical measurement of reduction quality and of mechanical integrity of fixation, respectively, meet this need.

Plain film measurement error in acute displaced midshaft clavicle fractures.

BACKGROUND: Clavicle fractures are common and optimal treatment remains controversial. Recent literature suggests operative fixation of acute displaced mid-shaft clavicle fractures (DMCFs) shortened more than 2 cm improves outcomes. We aimed to identify correlation between plain film and computed tomography (CT) measurement of displacement and the inter- and intraobserver reliability of repeated radiographic measurements. METHODS: We obtained radiographs and CT scans of patients with acute DMCFs. Three orthopedic staff and 3 residents measured radiographic displacement at time zero and 2 weeks later. The CT measurements identified absolute shortening in 3 dimensions (by subtracting the length of the fractured from the intact clavicle). We then compared shortening measured on radiographs and shortening measured in 3 dimensions on CT. Interobserver and intraobserver reliability were calculated. RESULTS: We reviewed the fractures of 22 patients. Bland-Altman repeatability coefficient calculations indicated that radiograph and CT measurements of shortening could not be correlated owing to an unacceptable amount of measurement error (6 cm). Interobserver reliability for plain radiograph measurements was excellent (Cronbach α = 0.90). Likewise, intraobserver reliabilities for plain radiograph measurements as calculated with paired t tests indicated excellent correlation (p > 0.05 in all but 1 observer [p = 0.04]). CONCLUSION: To establish shortening as an indication for DMCF fixation, reliable measurement tools are required. The low correlation between plain film and CT measurements we observed suggests further research is necessary to establish what imaging modality reliably predicts shortening. Our results indicate weak correlation between radiograph and CT measurement of acute DMCF shortening.

CONTEXTE: Les fractures de la clavicule sont fréquentes, et le choix du traitement optimal ne fait pas l'unanimité. Selon la littérature récente, la fixation chirurgicale des fractures du tiers médial déplacées (FTMD) aiguës raccourcies de plus de 2 cm donnerait de meilleurs résultats. Nous avons voulu établir une corrélation entre la mesure du déplacement obtenue par radiographie simple et par tomodensitométrie (TDM) et la fiabilité inter- et intra-observateur des mesures radiographiques répétées. MÉTHODES: Nous avons obtenu les radiographies et les TDM de patients ayant subi une FTMD aiguë. Trois orthopédistes et 3 résidents ont mesuré le déplacement radiographique au temps zéro et 2 semaines plus tard. Les mesures par TDM ont permis d'identifier un raccourcissement absolu en 3 dimensions (en soustrayant de la longueur de la clavicule intacte celle de la clavicule brisée). Nous avons ensuite comparé le raccourcissement mesuré par radiographie au raccourcissement en 3 dimensions mesuré par TDM. La fiabilité inter- et intra-observateur a ensuite été calculée. RÉSULTATS: Nous avons ainsi analysé les fractures de 22 patients. Les calculs du coefficient de répétabilité de Bland et Altman ont indiqué qu'il était impossible d'établir des corrélations entre les mesures obtenues par radiographie et par TDM compte tenu de l'ampleur inacceptable de l'erreur de mesure (6 cm). La fiabilité inter-observateur a été excellente pour les mesures radiographiques (coefficient α de Cronbach = 0,90). De même, la fiabilité intra-observateur pour les mesures radiographiques calculée par test t pour échantillons appariés a indiqué une excellente corrélation (p > 0,05 chez tous les observateurs, sauf 1 [p = 0,04]). CONCLUSION: Pour que le raccourcissement devienne une indication de la FTMD, il faut disposer d'outils de mesure fiables. La faible corrélation que nous avons observée entre les mesures obtenues par radiographie et par TDM montre qu'il faut approfondir la recherche afin de déterminer quelle modalité permet de prédire de manière fiable le raccourcissement. Nos résultats démontrent une faible corrélation entre les mesures du raccourcissement obtenues par radiographie et par TDM dans la FTMD aiguë.

Use of the National Surgical Quality Improvement Program in orthopaedic surgery.

BACKGROUND: The goal of the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) is to improve patient safety. The database has been used by hospitals across the United States to decrease the rate of adverse events and improve surgical outcomes, including dramatic decreases in 30-day mortality, morbidity, and complication rates. However, only a few orthopaedic surgical studies have employed the ACS NSQIP database, all of which have limited their analysis to either single orthopaedic procedures or reported rates of adverse events without considering the effect of patient characteristics and comorbidities. QUESTION/PURPOSES: Our specific purposes included (1) investigating the most common orthopaedic procedures and 30-day adverse events, (2) analyzing the proportion of adverse events in the top 30 most frequently identified orthopaedic procedures, and (3) identifying patient characteristics and clinical risk factors for adverse events in patients undergoing hip fracture repair. METHODS: We used data from the ACS NSQIP database to identify a large prospective cohort of patients undergoing orthopaedic surgery procedures from 2005 to 2011 in more than 400 hospitals around the world. Outcome variables were separated into the following three categories: any complication, minor complication, and major complication. The rate of adverse events for the top 30 orthopaedic procedures was calculated. Bivariate and multivariate analyses were used to determine risk factors for each of the outcome variables for hip fracture repair. RESULTS: Of the 1,979,084 surgical patients identified in the database, 146,774 underwent orthopaedic procedures (7%). Of the 30 most common orthopaedic procedures, the top three were TKA, THA, and knee arthroscopy with meniscectomy, which together comprised 55% of patients (55,575 of 101,862). We identified 5368 complications within the top 30 orthopaedic procedures, representing a 5% complication rate. The minor and major complication rates were 3.1% (n = 3174) and 2.8% (n = 2880), respectively. The most common minor complication identified was urinary tract infection (n = 1534) and the most common major complication identified was death (n = 850). An American Society of Anesthesiologists class of 3 or higher was a consistent risk factor for all three categories of complications in patients undergoing hip fracture repair. CONCLUSIONS: The ACS NSQIP database allows for evaluating current trends of adverse events in selected surgical specialties. However, variables specific to orthopaedic surgery, such as open versus closed injury, are needed to improve the quality of the results.

Current Practice in the Management of Type I Open Fractures in Children: A Survey of POSNA Membership.

BACKGROUND: Treatment of pediatric type I open fractures is controversial. Centers have reported good success with emergency room (ER) treatment of low-energy (type I) open pediatric fractures. The purpose of this study was to ascertain the treatment preferences of pediatric orthopaedic surgeons for type I open fractures. We hypothesize that surgeons will have different treatment protocols and preferred location for these injuries. METHODS: A questionnaire was given to Pediatric Orthopaedic Society of North America (POSNA) members at the 2012 annual meeting. Demographic questions inquired about surgeon's practice environment and experience, whereas clinical questions queried opinions regarding the typical treatments and past experiences with open fractures. Clinical scenarios questioned preferred management of open fractures. RESULTS: A total of 181 surveys were collected from the 503 POSNA members in attendance (36%). Years in practice were well represented with 34%: <10 years, 37%: 10 to 19 years, and 29%: >20 years. Most respondents' practices comprised over 80% pediatric patients (86%), were academic (68%), and worked with residents (77%). After initial treatment of an open fracture, 86% of respondents admitted patients for intravenous antibiotics and 57% gave oral antibiotics. There was no consensus regarding the amount or type of irrigation preferred, use of antibiotics in the irrigation, or whether the bone ends are delivered during irrigation and débridement. Soft-tissue infections and delayed union were noted by 13% and 8%, respectively, of respondents in type I open fractures treated in the ER and in 16% and 30% treated in the operating room (OR). ER treatment was preferred in 19% to 31% of respondents for type I open fractures. When queried if level 1 evidence existed that demonstrated equivalent results between ER and OR management, 92% of respondents would change their practice. CONCLUSIONS: Treatment methods of type I open fractures are variable. Many surgeons prefer to treat type I open fractures in the ER as opposed to the traditional OR irrigation and débridement. On the basis of this survey, either children are going to the OR when ER treatment would be adequate or they may be receiving inadequate care when they avoid OR management. This survey establishes the equipoise necessary for a randomized, prospective trial comparing ER and OR management in the treatment of pediatric type I open fractures.

[Femoral shaft fractures in children under 3 years old. Current treatment standard]. / Femurschaftfrakturen bei Kindern unter 3 Jahren. Aktueller Behandlungsstandard.

INTRODUCTION: Femoral shaft fractures in children are a common injury. Operative treatment is recommended for children above 3 years of age. The question of this investigation was the current clinical standard for the treatment of femoral shaft fractures in children under 3 years old. MATERIAL AND METHODS: An e-mail questionnaire was sent to all clinics and hospital departments of the members of the German Society for Trauma Surgery and the German Society of Pediatric Surgery. RESULTS: Out of 775 clinics and departments, 121 participated in the survey (16 %). From 2011 to 2012 overall 756 femoral shaft fractures of children 3 years and younger were treated of which 375 (50 %) were stabilized with elastic stable intramedullary nailing (ESIN), 183 (24 %) with an overhead extension, 178 (23 %) with a plaster cast and 9 (1 %) with external fixation. Finally, operative treatment was used in 51 % compared to 49 % with conservative treatment. DISCUSSION: Obviously, operative treatment of femoral shaft fractures in children younger than 3 years is routinely used despite the fact that there is no evidential basis for this approach. There are good arguments for and against operative and conservative forms of treatment. Indications for operative treatment include multiple trauma, open fractures, body weight over 20 kg, child already free walking and lack of stable fixation with conservative treatment. To achieve more evidence for the existing recommendation of the American Academy of Orthopaedic Surgeons (AAOS) and the Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF, Working Group of the Scientific Medical Specialist Societies), further investigations are needed.

Nationwide Inpatient Sample and National Surgical Quality Improvement Program give different results in hip fracture studies.

BACKGROUND: National databases are being used with increasing frequency to conduct orthopaedic research. However, there are important differences in these databases, which could result in different answers to similar questions; this important potential limitation pertaining to database research in orthopaedic surgery has not been adequately explored. QUESTIONS/PURPOSES: The purpose of this study was to explore the interdatabase reliability of two commonly used national databases, the Nationwide Inpatient Sample (NIS) and the National Surgical Quality Improvement Program (NSQIP), in terms of (1) demographics; (2) comorbidities; and (3) adverse events. In addition, using the NSQIP database, we identified (4) adverse events that had a higher prevalence after rather than before discharge, which has important implications for interpretation of studies conducted in the NIS. METHODS: A retrospective cohort study of patients undergoing operative stabilization of transcervical and intertrochanteric hip fractures during 2009 to 2011 was performed in the NIS and NSQIP. Totals of 122,712 and 5021 patients were included from the NIS and NSQIP, respectively. Age, sex, fracture type, and lengths of stay were compared. Comorbidities common to both databases were compared in terms of more or less than twofold difference between the two databases. Similar comparisons were made for adverse events. Finally, adverse events that had a greater postdischarge prevalence were identified from the NSQIP database. Tests for statistical difference were thought to be of little value given the large sample size and the resulting fact that statistical differences would have been identified even for small, clinically inconsequential differences resulting from the associated high power. Because it is of greater clinical importance to focus on the magnitude of differences, the databases were compared by absolute differences. RESULTS: Demographics and hospital lengths of stay were not different between the two databases. In terms of comorbidities, the prevalences of nonmorbid obesity, coagulopathy, and anemia in found in the NSQIP were more than twice those in the NIS; the prevalence of peripheral vascular disease in the NIS was more than twice that in the NSQIP. Four other comorbidities had prevalences that were not different between the two databases. In terms of inpatient adverse events, the frequencies of acute kidney injury and urinary tract infection in the NIS were more than twice those in the NSQIP. Ten other inpatient adverse events had frequencies that were not different between the two databases. Because it does not collect data after patient discharge, it can be implied from the NSQIP data that the NIS does not capture more than ½ of the deaths and surgical site infections occurring during the first 30 postoperative days. CONCLUSIONS: This study shows that two databases commonly used in orthopaedic research can identify similar populations of operative patients but may generate very different results for specific commonly studied comorbidities and adverse events. The NSQIP identified higher rates of morbid obesity, coagulopathy, and anemia. The NIS identified higher rates of peripheral vascular disease, acute kidney injury, and urinary tract infection. LEVEL OF EVIDENCE: Level II, prognostic study. See the Instructions for Authors for a complete description of levels of evidence.

Attempting primary closure for all open fractures: the effectiveness of an institutional protocol.

BACKGROUND: Immediate primary closure of open fractures has been historically believed to increase the risk of wound infection and fracture nonunion. Recent literature has challenged this belief, but uncertainty remains as to whether primary closure can be used as routine practice. This study evaluates the impact of an institutional protocol mandating primary closure for all open fractures. METHODS: We retrospectively reviewed all open fractures treated in a single level 1 trauma centre in a 5-year period. Prior to the study, a protocol was adopted standardizing management of open fractures and advocating primary closure of all wounds as a necessary goal of operative treatment. Patient and fracture characteristics, type of wound closure and development of infectious and bone healing complications were evaluated from time of injury to completion of outpatient follow-up. RESULTS: A total of 297 open fractures were treated, 255 (85.8%) of them with immediate primary closure. Type III open injuries accounted for 24% of all injuries. Wounds that were immediately closed had a superficial infection rate of 11% and a deep infection rate of 4.7%. Both proportions are equivalent to or lower than historical controls for delayed closure. Fracture classification, velocity of trauma and time to wound closure did not correlate significantly with infection, delayed union or nonunion. CONCLUSION: Attempting primary closure for all open fractures is a safe and efficient practice that does not increase the postoperative risk of infection and delayed union or nonunion.

CONTEXTE: On a de tout temps cru que la fermeture primaire immédiate des fractures ouvertes accroissait le risque d'infection de la plaie et de non soudure osseuse. La littérature récente remet cette position en question, mais on ignore encore si la fermeture primaire peut être utilisée de routine. Cette étude évalue l'impact d'un protocole d'établissement imposant la fermeture primaire de toutes les fractures ouvertes. MÉTHODES: Nous avons passé en revue de manière rétrospective toutes les fractures ouvertes traitées dans un seul centre de traumatologie de Niveau 1 au cours d'une période de 5 ans. Avant l'étude, un protocole a été adopté pour standardiser la prise en charge des fractures ouvertes et promouvoir la fermeture primaire de toutes les plaies comme objectif imposé du traitement opératoire. Les caractéristiques des patients et des fractures, les types de fermeture de plaie et les complications infectieuses ou liées à la guérison osseuse ont été évalués à partir du moment de la blessure et jusqu'à la fin du suivi en clinique externe. RÉSULTATS: En tout, 297 fractures ouvertes ont été traitées, 255 d'entre elles (85,8 %), au moyen d'une fermeture primaire immédiate. Les traumatismes ouverts de Type III comptaient pour 24 % de toutes les blessures. Les plaies qui ont été refermées immédiatement ont présenté un taux d'infection superficielle de 11 % et un taux d'infection profonde de 4,7 %. Ces 2 proportions sont équivalentes ou inférieures à ce qui a été observé chez les témoins historiques chez qui la fermeture de plaie a été reportée. La classification des fractures, la vitesse de l'impact à l'origine des traumatismes et le temps écoulé avant la fermeture des plaies n'ont pas été en corrélation significative avec l'infection et le retard de soudure osseuse ou la non soudure osseuse. CONCLUSION: Tenter d'appliquer une fermeture primaire à toutes les fractures ouvertes est une pratique sécuritaire et efficace qui n'accroît pas le risque d'infection postopératoire, de retard de soudure osseuse ou de non soudure osseuse.

'Do Not Attempt Resuscitation' (DNAR) decisions in patients with femoral fractures: modification, clinical management and outcome.

BACKGROUND: increased provision of orthogeriatric expertise for patients with femoral fractures has led to implementation of 'Do Not Attempt Resuscitation' (DNAR) decisions prior to anaesthesia and surgery for fixation of their fractures. Review and modification of the DNAR decision by the medical team is necessary before surgery and is recommended by guidelines from the Association of Anaesthetists of Great Britain and Ireland (AAGBI) and the General Medical Council. METHODS: over a 17-month period, DNAR decisions were already present or were implemented for the first time in 22 patients prior to scheduled surgical fixation of their femoral fractures. Data were collected prospectively on each patient's management, including modification of their DNAR decision, and outcome at 30 days and 1 year. RESULTS: two patients died prior to surgery. In eight of the 20 patients who underwent surgical fixation, there was no documentation regarding the status of the DNAR decision in the perioperative period. The 30-day mortality rate for those undergoing surgery was 15% (3/20). At 1 year, eight patients survived with six living in their own homes. CONCLUSIONS: despite the favourable outcomes for hip fracture patients with pre-existing DNAR decisions, this audit showed inadequate review and documentation of the DNAR decision in advance of surgery.

The use of weekly departmental review of all orthopaedic intra-operative radiographs in order to improve quality, due to standardized peer expectations and the "Hawthorne effect".

INTRODUCTION: Clinical governance highlights risk management, clinical effectiveness and use of evidence based practice as key elements in the provision of a quality service. A change in the method of quality control in our orthopaedic trauma unit allowed us the opportunity to study if the quality of operative outcomes had changed as a result. The Hawthorne effect refers to phenomenon whereby employees work quality improves by virtue of their awareness that their labour is being assessed. METHODS: A new outcome appraisal forum was introduced in our department in 2009. This forum involved a weekly whole department review of all the previous week's intraoperative radiographs. We used the tip apex distance (TAD) of the dynamic hip screw (DHS) procedures in hip fracture patients as a surrogate marker, of any objective change in the quality and consistency of intra-operative radiographs, in the year prior to and after the introduction of this review system. RESULTS: We found that the mean TAD and the number of TAD measurements over 25 mm decreased significantly in the year after the new quality control mechanism was introduced. CONCLUSION: We would recommend the use of a weekly quality control meeting scrutinizing every intraoperative radiograph as a simple, cost effective method of incorporating many aspects of clinical governance, as well as fostering a culture of quality.

Improved bonding of partially osteomyelitic bone to titanium pins owing to biomimetic coating of apatite.

Increased fixation strength of the bone-pin interface is important for inhibiting pin loosening after external fixation. In a previous study, an apatite (Ap) layer was formed on anodically oxidized titanium (Ti) pins by immersing them in an infusion fluid-based supersaturated calcium phosphate solution at 37 °C for 48 h. In the present study, an Ap layer was also successfully formed using a one-step method at 25 °C for 24 h in an infusion fluid-based supersaturated calcium phosphate solution, which is clinically useful due to the immersion temperature [corrected]. After percutaneous implantation in a proximal tibial metaphysis for four weeks in rabbits (n = 20), the Ti pin coated with the Ap layer showed significantly increased extraction torque compared with that of an uncoated Ti screw even with partial osteomyelitis present, owing to dense bone formation on the Ap layer in the cortical and medullary cavity regions. When the infection status was changed from "no osteomyelitis" to "partial osteomyelitis," the extraction torque in the Ap group with "partial osteomyelitis" was almost identical to that for "no osteomyelitis" cases. These results suggest that the Ap layer formed by the room temperature process could effectively improve the fixation strength of the Ti pin for external fixation clinically even with partial osteomyelitis present.

[Exploration and consideration on establishing a core outcome set of Traditional Chinese Medicine clinical trials in distal radius fracture].

There are inconsistencies in treatment outcomes, measurement instruments, and criteria for assessing clinical effectiveness in studies related to distal radius fractures (DRF), resulting in potential biases and failing to provide high-quality clinical evidence. To address these challenges, international researchers have reached a consensus on developing the core outcome indicator set for distal radius fractures(COS-DRF). However, it's important to note that the existing COS-DRF framework could not reflect the unique characteristics of Traditional Chinese Medicine (TCM) treatment. Currently, there are no established standards for treatment outcomes and measurement instruments specific to TCM clinical research, nor has a COS-DRF been established for TCM clinical studies in China. In light of these gaps, our research team aims to construct a core set of treatment outcomes for TCM clinical research on distal radius fractures. This involves compiling a comprehensive list of treatment outcomes and measurement instruments, initially derived from a thorough literature review and expert consensus, which will then undergo further refinement and updates based on real-world clinical experiences, incorporating feedback from 2 to 3 rounds of expert consensus or Delphi questionnaire surveys. Our goal is to establish a COS-DRF or CMS-DRF that aligns with the principles and practices of TCM, and provide high-quality evidence for clinical practice.
