Multicenter, Prospective, Observational Study of Nonoperative Versus Operative Treatment for High-Energy Midshaft Clavicle Fractures.

OBJECTIVES: Evaluate if nonoperative or operative treatment of displaced clavicle fractures delivers reduced rates of nonunion and improved Disability of the Arm, Shoulder, and Hand (DASH) scores. DESIGN: Multicenter, prospective, observational. SETTING: Seven Level 1 Trauma Centers in the United States. PATIENT SELECTION CRITERIA: Adults with closed, displaced (100% displacement/shortened >1.5 cm) midshaft clavicle fractures (Orthopaedic Trauma Association 15.2) were treated nonoperatively, with plates and screw fixation, or with intramedullary fixation from 2003 to 2018. OUTCOME MEASURES AND COMPARISONS: DASH scores (2, 6 weeks, 3, 6, 12, and 24 months), reoperation, and nonunion were compared between the nonoperative, plate fixation, and intramedullary fixation groups. RESULTS: Four hundred twelve patients were enrolled, with 203 undergoing plate fixation, 26 receiving intramedullary fixation, and 183 treated nonoperatively. The average age of the nonoperative group was 40.1 (range 18-79) years versus 35.8 (range 18-74) in the plate group and 39.3 (range 19-56) in the intramedullary fixation group (P = 0.06). One hundred forty (76.5%) patients in the nonoperative group were male compared with 154 (75.9%) in the plate group and 18 (69.2%) in the intramedullary fixation group (P = 0.69). All groups showed similar DASH scores at 2 weeks, 12 months, and 24 months (P > 0.05). Plate fixation demonstrated better DASH scores (median = 20.8) than nonoperative (median = 28.3) at 6 weeks (P = 0.04). Intramedullary fixation had poorer DASH scores at 6 weeks, 3 months, and 6 months than plate fixation and worse DASH scores than nonoperative at 6 months (P < 0.05). The nonunion rate for nonoperative treatment (14.6%) was significantly higher than the plate group (0%) (P < 0.001). CONCLUSIONS: Operative treatment of displaced clavicle fractures provided lower rates of nonunion than nonoperative treatment. Except at 6 weeks, no difference was observed in DASH scores between plate fixation and nonoperative treatment. Intramedullary fixation resulted in worse DASH scores than plate fixation at 6 weeks, 3 months, and 6 months and worse DASH scores than nonoperative at 6 months. Implant removal was the leading reason for reoperation in the plate and intramedullary fixation groups, whereas surgery for nonunion was the primary reason for surgery in the nonoperative group.

Geriatric trauma: there is more to it than just the implant!

Geriatric trauma continues to rise, corresponding with the continuing growth of the older population. These fractures continue to expand, demonstrated by the incidence of hip fractures having grown to 1.5 million adults worldwide per year. This patient population and their associated fracture patterns present unique challenges to the surgeon, as well as having a profound economic impact on the health care system. Pharmacologic treatment has focused on prevention, with aging adults having impaired fracture healing in addition to diminished bone mineral density. Intraoperatively, novel ideas to assess fracture reduction to facilitate decreased fracture collapse have recently been explored. Postoperatively, pharmacologic avenues have focused on future fracture prevention, while shared care models between geriatrics and orthopaedics have shown promise regarding decreasing mortality and length of stay. As geriatric trauma continues to grow, it is imperative that we look to optimize all phases of care, from preoperative to postoperative.

Midshaft clavicle fractures: is anterior plating an acceptable alternative to superior plating?

PURPOSE: The purpose of this study was to determine whether anterior plating is better tolerated than superior plating for midshaft clavicle fractures. METHODS: This was a prospective non-randomized observational cohort study following operative vs. non-operative management of clavicle fractures from 2003 to 2018 at 7 level 1 academic trauma centers in the USA. The subset of patients treated with plate and screws is the basis for this comparative study. Adults aged 18-85 with closed clavicle fractures displaced over 100% or shortened by more than 1.5 cm were eligible for enrollment. Patients were followed for 2 years following enrollment. Allowable fixation methods at the discretion of the surgeon consisted of anterior-inferior or superior plating. A total of 412 patients were enrolled. Of these, 192 patients received either superior or anterior plating for a displaced clavicle fracture with complete documented prospective research forms capturing type of plating technique. The primary outcome measure was hardware removal (HWR). Secondary outcomes were Disability of the Arm Shoulder and Hand (DASH) score and Visual Analog Pain (VAP) score, and satisfaction score (1 = high satisfaction; 5 = low satisfaction). RESULTS: There was no difference in HWR rates (7.1% superior 9/127; 6.2% anterior 4/65, p = 0.81), VAP score (mean 1.5 SD 1.0 superior; mean 1.7 SD 0.6 anterior, p = 0.21), DASH score (mean 7.5 SD 12.4 superior; mean 5.2 SD 15.2 anterior; p = 0.18) or satisfaction score (mean 1.6 SD 1.0 superior; mean 1.7 SD 0.60 anterior, p = 0.18). CONCLUSION: There is no difference in HWR rates or functional outcomes when using a superior vs. anterior plating technique.

Posttraumatic Patellar Osteomyelitis due to Raoultella ornithinolytica: A Case Report.

CASE: A 59-year-old woman sustained a comminuted patellar fracture after a fall from standing. The injury was treated with open reduction and internal fixation 7 days from initial injury. Seven weeks postoperatively, she developed a swollen, painful, and draining knee. Workup demonstrated Raoultella ornithinolytica. She underwent surgical debridement and antibiotic treatment. CONCLUSION: This is an unusual presentation of patellar osteomyelitis with R. ornithinolytica. Early identification, treatment with appropriate antimicrobial therapy, and consideration of surgical debridement are important in patients presenting with pain, swelling, and erythema after surgery.

An Evaluation of Treatment Patterns for Osteoporosis and Outcomes After a Fragility Fracture in a Real-World Setting.

OBJECTIVES: Treatment initiation and persistence after a fragility fracture are critical to reduce the risk of subsequent fractures. The authors evaluated osteoporosis management and outcomes after index fracture. METHODS: This retrospective cohort study used real-world data for patients (≥50 years), including pharmacy claims linked to commercial and Medicare medical claims from Symphony Health Patient Source. Osteoporosis management was evaluated for at least 12 months after the first case-qualifying fracture during the identification period and continued until a second fracture or March 31, 2020 (depending on data availability). Secondary fracture incidence was evaluated overall and for subgroups at very high risk. RESULTS: Of 755,312 eligible patients, the proportion with a claim for bone mineral density testing at 12 months after index fracture was low [64,932 (8.6%)], and 75.3% of those tested were ≥65 years of age. Most patients (88.6%) remained untreated at any time after fracture. Among those treated, most (64.9%) were initially treated with bisphosphonates (oral, 93.7%; IV, 6.3%). Treatment duration and persistence were low for all treatments ranging from 6.5 months with 19.6% persistent for abaloparatide to 11.3 months with 45.0% persistent for denosumab. During follow-up, 13.6% of patients had a secondary fracture at any site, with higher incidence in subgroups considered to be at high risk for fracture than in the overall population. CONCLUSIONS: Low rates of osteoporosis testing and treatment initiation and high secondary fracture rates (particularly among patients at very high risk) highlight the need for better management of patients after a fracture. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Change in Gustilo-Anderson classification at time of surgery does not increase risk for surgical site infection in patients with open fractures: A secondary analysis of a multicenter, prospective randomized controlled trial.

Introduction: Open fractures represent a major source of morbidity. Surgical site infections (SSIs) after open fractures are associated with a high rate of reoperations and hospitalizations, which are associated with a lower health-related quality of life. Early antibiotic delivery, typically chosen through an assessment of the size and contamination of the wound, has been shown to be an effective technique to reduce the risk of SSI in open fractures. The Gustilo-Anderson classification (GAC) was devised as a grading system of open fractures after a complete operative debridement of the wound had been undertaken but is commonly used preoperatively to help with the choice of initial antibiotics. Incorrect preoperative GAC, leading to less aggressive initial management, may influence the risk of SSI after open fracture. The objectives of this study were to determine (1) how often the GAC changed from the initial to definitive grading, (2) the injury and patient characteristics associated with increases and decreases of the GAC, and (3) whether a change in GAC was associated with an increased risk of SSI. Methods: Using data from the FLOW trial, a large multicenter randomized study, we used descriptive statistics to quantify how frequently the GAC changed from the initial to definitive grading. We used regression models to determine which injury and patient characteristics were associated with increases and decreases in GAC and whether a change in GAC was associated with SSI. Results: Of the 2420 participants included, 305 participants had their preoperative GAC change (12.6%). The factors associated with upgrading the GAC (from preoperative score to the definitive assessment) included fracture sites other than the tibia, bone loss at presentation, width of wound, length of wound, and skin loss at presentation. However, initial misclassification of type III fractures as type II fractures was not associated with an increased risk of SSI (P = 0.14). Conclusions: When treating patients with open fracture wounds, surgeons should consider that 12% of all injuries may initially be misclassified when using the GAC, particularly fractures that have bone loss at presentation or those located in sites different than the tibia. However, even in misclassified fractures, it did not seem to increase the risk of SSI.

Analysis of 101 Mechanical Failures in Distal Femur Fractures Treated with 3 Generations of Precontoured Locking Plates.

OBJECTIVES: To evaluate mechanical treatment failure in a large patient cohort sustaining a distal femur fracture treated with a distal femoral locking plate (DFLP). DESIGN: This retrospective case-control series evaluated mechanical treatment failures of DFLPs. SETTING: The study was conducted at 8 Level I trauma centers from 2010 to 2017. PATIENTS AND PARTICIPANTS: One hundred one patients sustaining OTA/AO 33-A and C distal femur fractures were treated with DFLPs that experienced mechanical failure. INTERVENTION: The intervention included the treatment of a distal femur fracture with a DFLP, affected by mechanical failure (implant failure by loosening or breakage). MAIN OUTCOME MEASURE: The main outcome measures included injury and DFLP details; modes and timing of failure were studied. RESULTS: One hundred forty-six nonunions were found overall (13.4%) including 101 mechanical failures (9.3%). Failures occurred in different manners, locations, and times depending on the DFLPs. For example, 33 of 101 stainless steel (SS) plates (33%) failed by bending or breaking in the working length, whereas no Ti plates failed here ( P < 0.05). Eleven of 12 failures with titanium-Less Invasive Stabilization System (92%) occurred by lost shaft fixation, mostly by the loosening of unicortical screws (91%). Sixteen of 44 variable -angled-LCP failures (36%) occurred at the distal plate-screw junction, whereas only 5 of 61 other DFLPs (8%) failed this way ( P < 0.05). Distal failures occurred on average at 23.7 weeks compared with others that occurred at 38.4 weeks ( P < 0.05). Variable -angled-LCP distal screw-plate junction failures occurred earlier (mean 21.4 weeks). CONCLUSION: Nonunion and mechanical failure occurred in 14% and 9% of patients, respectively, in this large series of distal femur fracture treated with a DFLP. The mode, location, presence of a prosthesis, and timing of failure varied depending on the characteristics of DFLP. This information should be used to optimize implant usage and design to prolong the period of stable fixation before potential implant failures occur in patients with a prolonged time to union.

Bone Health Management in Elective Orthopaedic Surgery: A Claims-Based Observational Study.

Introduction: There are limited data on the management of bone health, including bone mineral density (BMD) evaluation and osteoporosis (OP) treatment, in patients undergoing elective orthopaedic surgeries. Methods: This was a retrospective cohort study using administrative claims data from Symphony Health, PatientSource for patients aged ≥50 years with documented kyphoplasty/vertebroplasty (KP/VP), total knee arthroplasty (TKA), and total hip arthroplasty (THA). Risk stratification to identify patients at very high risk for fracture (VHRFx) was based on clinical practice guideline recommendations to the extent information on variables of interest were available from the claims database. Results: A total of 251 919 patients met inclusion criteria: KP/VP (31 018), TKA (149 849), and THA (71 052). The majority were female (80.3%) with a mean (SD) age of 68.5 (7.5) years. Patients undergoing KP/VP were older and had a greater comorbidity burden associated with risk for falls, mobility issues, muscle weakness, and respiratory and cardiovascular diseases. In the 6 months before surgery, 11.8% of patients were tested and/or received treatment for OP. Patients undergoing KP/VP were more likely to be tested and/or treated (17.5%) than patients undergoing TKA (11.0%) or THA (10.9%). Overall, men had a lower rate of testing and/or treatment than women (4.6% vs 13.5%). In the 12 months before surgery, patients with an OP diagnosis and at VHRFx (30.8%) had a higher rate of treatment and/or testing than those without OP (11.5%), or those without OP but with a fracture in the year preceding surgery (10.2%). Conclusions: Bone health management is suboptimal in patients undergoing elective orthopaedic surgeries and is worse in men than in women. Proper management of OP before and after surgery may improve outcomes.

Serology and Comorbidities in Patients With Fracture Nonunion: A Multicenter Evaluation of 640 Patients.

INTRODUCTION: This multicenter cohort study investigated the association of serology and comorbid conditions with septic and aseptic nonunion. METHODS: From January 1, 2011, to December 31, 2017, consecutive individuals surgically treated for nonunion were identified from seven centers. Nonunion-type, comorbid conditions and serology were assessed. RESULTS: A total of 640 individuals were included. 57% were male with a mean age of 49 years. Nonunion sites included tibia (35.2%), femur (25.6%), humerus (20.3%), and other less frequent bones (18.9%). The type of nonunion included septic (17.7%) and aseptic (82.3%). Within aseptic, nonvascular (86.5%) and vascular (13.5%) nonunion were seen. Rates of smoking, alcohol abuse, and diabetes mellitus were higher in our nonunion cohort compared with population norms. Coronary artery disease and tobacco use were associated with septic nonunion (P < 0.05). Diphosphonates were associated with vascular nonunion (P < 0.05). Serologically, increased erythrocyte sedimentation rate, C-reactive protein, parathyroid hormone, red cell distribution width, mean platelet volume (MPV), and platelets and decreased absolute lymphocyte count, hemoglobin, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and albumin were associated with septic nonunion while lower calcium was associated with nonvascular nonunion (P < 0.05). The presence of four or more of increased erythrocyte sedimentation rate, C-reactive protein, or red cell distribution width; decreased albumin; and age younger than 65 years carried an 89% positive predictive value for infection. Hypovitaminosis D was seen less frequently than reported in the general population, whereas anemia was more common. However, aside from hematologic and inflammatory indices, no other serology was abnormal more than 25% of the time. DISCUSSION: Abnormal serology and comorbid conditions, including smoking, alcohol abuse, and diabetes mellitus, are seen in nonunion; however, serologic abnormalities may be less common than previously thought. Septic nonunion is associated with inflammation, younger age, and malnourishment. Based on the observed frequency of abnormality, routine laboratory work is not recommended for nonunion assessment; however, specific focused serology may help determine the presence of septic nonunion.

Osteoporosis management in the United States.

There are numerous organizational osteoporosis initiatives in the United States offering a variety of recommendations and guidelines. A common method of implementing these goals is centered around multidisciplinary provider teams with the broad task of diagnosis, treatment, and prevention of current and future osteoporosis related fractures. These teams have generally proved to be successful even though it remains debated, which specific provider specialty is ultimately responsible for osteoporosis care. The current United States healthcare infrastructure represents the significant obstacle in widespread adoption of successful treatment programs. The development of further quality standards and incorporation of fracture liaison services into reimbursement and funding models will allow for continued improvement in osteoporosis care.

Does negative pressure wound therapy reduce the odds of infection and improve health-related quality of life in patients with open fractures?

AIMS: To evaluate the impact of negative pressure wound therapy (NPWT) on the odds of having deep infections and health-related quality of life (HRQoL) following open fractures. METHODS: Patients from the Fluid Lavage in Open Fracture Wounds (FLOW) trial with Gustilo-Anderson grade II or III open fractures within the lower limb were included in this secondary analysis. Using mixed effects logistic regression, we assessed the impact of NPWT on deep wound infection requiring surgical intervention within 12 months post-injury. Using multilevel model analyses, we evaluated the impact of NPWT on the Physical Component Summary (PCS) of the 12-Item Short-Form Health Survey (SF-12) at 12 months post-injury. RESULTS: After applying inverse probability treatment weighting to adjust for the influence of injury characteristics on type of dressing used, 1,322 participants were assessed. The odds of developing a deep infection requiring operative management within 12 months of initial surgery was 4.52-times higher in patients who received NPWT compared to those who received a standard wound dressing (95% confidence interval (CI) 1.84 to 11.12; p = 0.001). Overall, 1,040 participants were included in our HRQoL analysis, and those treated with NPWT had statistically significantly lower mean SF-12 PCS post-fracture (p < 0.001). These differences did not reach the minimally important difference for the SF-12 PCS. CONCLUSION: Our analysis found that patients treated with NPWT had higher odds of developing a deep infection requiring operative management within 12 months post-fracture. Due to possible residual confounding with the worst cases being treated with NPWT, we are unable to determine if NPWT has a negative effect or is simply a marker of worse injuries or poor access to early soft-tissue coverage. Regardless, our results suggest that the use of this treatment requires further evaluation. Cite this article: Bone Jt Open 2022;3(3):189-195.

Allies in Orthopaedic Trauma Surgery.

From the casting couch to the board room, the media, and beyond, the topic of sexual harassment and bullying can no longer be ignored. Sexual harassment and bullying in medicine has the potential to be the next big headline on these topics. The culture in medicine and especially the hierarchy in surgery often permit this behavior. To improve the culture in orthopaedic surgery regarding sexual harassment and bullying, education must occur. With education, comes acknowledgment and recognition. This permits an ability to act on and improve the culture. This paper will start the dialogue of this difficult topic and provide a call to action for sexual harassment and bullying to become "Never events".

Traumatic Arthrotomies: Do They All Need the Operating Room?

OBJECTIVES: To compare complications and cost of care in patients with traumatic arthrotomies (TAs) treated with surgical debridement, irrigation, and closure to those treated with nonoperative treatment and local wound care. DESIGN: This is a prospective observational multicenter study. SETTING: This study was conducted at multiple Level I trauma centers. PATIENTS: Patients with TAs. INTERVENTION: Patients were treated with operative versus nonoperative management decided by the attending surgeon. Nonoperative treatment of TAs included bedside irrigation, primary closure, antibiotics, and discharge from the emergency department with close follow-up unless admission was otherwise indicated. MAIN OUTCOME MEASUREMENTS: Primary outcomes included adverse outcomes and cost. VR-12 was captured at the time of injury and 3 months postinjury. RESULTS: Of 189 major joint TAs, 64 arthrotomies were treated nonoperatively and 125 operatively. Seventy percent of the arthrotomies in the nonoperative group were small (less than 50 mm in size) and 95% had minimal/no gross contamination, whereas the operative group (OG) had significantly more arthrotomies greater than 50 mm in size and with moderate/severe gross contamination. There was one septic joint in the nonoperative group (1.5%) and 7 in the OG (5.6%). Nonoperative treatment was associated with significantly lower total charges when compared with the OG. CONCLUSIONS: Although further study may still be needed, this study suggests that small, minimally contaminated TAs with no associated fracture have a low risk of adverse complications, can safely be treated nonoperatively, and are associated with a significantly decreased cost of care.

The effect of time to irrigation and debridement on the rate of reoperation in open fractures : a propensity score-based analysis of the Fluid Lavage of Open Wounds (FLOW) study.

AIMS: Despite long-standing dogma, a clear relationship between the timing of surgical irrigation and debridement (I&D) and the development of subsequent deep infection has not been established in the literature. Traditionally, I&D of an open fracture has been recommended within six hours of injury based on animal studies from the 1970s, however the clinical basis for this remains unclear. Using data from a multicentre randomized controlled trial of 2,447 open fracture patients, the primary objective of this secondary analysis is to determine if a relationship exists between timing of wound I&D (within six hours of injury vs beyond six hours) and subsequent reoperation rate for infection or healing complications within one year for patients with open limb fractures requiring surgical treatment. METHODS: To adjust for the influence of patient and injury characteristics on the timing of I&D, a propensity score was developed from the dataset. Propensity-adjusted regression allowed for a matched cohort analysis within the study population to determine if early irrigation put patients independently at risk for reoperation, while controlling for confounding factors. Results were reported as odds ratios (ORs), 95% confidence intervals (CIs), and p-values. All analyses were conducted using STATA 14. RESULTS: In total, 2,286 of 2,447 patients randomized to the trial from 41 orthopaedic trauma centres across five countries had complete data regarding time to I&D. Prior to matching, the patients managed with early I&D had a higher proportion requiring reoperation for infection or healing complications (17% vs 13%; p = 0.019), however this does not account for selection bias of more severe injuries preferentially being treated earlier. When accounting for propensity matching, early irrigation was not associated with reoperation (OR 0.71 (95% CI 0.47 to 1.07); p = 0.73). CONCLUSION: When accounting for other variables, late irrigation does not independently increase risk of reoperation. Cite this article: Bone Joint J 2021;103-B(6):1055-1062.

Effect of Tourniquet Use During Surgical Treatment of Open Fractures.

BACKGROUND: We sought to evaluate whether tourniquet use, with the resultant ischemia and reperfusion, during surgical treatment of an open lower-extremity fracture was associated with an increased risk of complications. METHODS: This is a retrospective cohort study of 1,351 patients who had an open lower-extremity fracture at or distal to the proximal aspect of the tibia and who participated in the FLOW (Fluid Lavage of Open Wounds) trial. The independent variable was intraoperative tourniquet use, and the primary outcome measures were adjudicated unplanned reoperation within 1 year of the injury and adjudicated nonoperative wound complications. RESULTS: Unplanned reoperation and nonoperative wound complications were roughly even between the no-tourniquet (18.7% and 19.1%, respectively) and tourniquet groups (17.8% and 20.8%) (p = 0.78 and p = 0.52). Following matching, as determined by model interactions, tourniquet use was a significant predictor of unplanned reoperation in Gustilo Type-IIIA (odds ratio, 3.60; 95% confidence interval, 1.16 to 11.78) and IIIB fractures (odds ratio, 16.61; 95% confidence interval, 2.15 to 355.40). CONCLUSIONS: The present study showed that tourniquet use did not influence the likelihood of complications following surgical treatment of an open lower-extremity fracture. However, in cases of severe open fractures, tourniquet use was associated with increased odds of unplanned reoperation; surgeons should be cautious with regard to tourniquet use in this setting.

Quality and Content of Internet-Based Information for Osteoporosis and Fragility Fracture Diagnoses.

INTRODUCTION: We aimed to assess the quality and content of websites addressing orthopaedic conditions affecting older adults, emphasizing osteoporosis and fragility fracture. METHODS: Ten diagnoses were chosen. The transparency of information was assessed via the Health On the Net (HON) score; information content was assessed via diagnosis-specific grading templates. A total of 140 websites (14 per diagnosis) were reviewed by three raters. HON scores and information quality were compared by diagnosis, website type, and website source. The correlation between HON score and information quality score was calculated. RESULTS: Most websites were commercial (59.3%). Cronbach alpha for Hall scores exceeded the a priori threshold of 0.7. Analysis proceeded using averages across raters. HON score was significantly associated with higher content scores (r = 0.56; P < 0.0001). Content scores ranged from 21.1 to 59.4. Content scores differed significantly by diagnosis (P = 0.0008) and website source (P < 0.0001). DISCUSSION: The quality and content of websites is highly variable for osteoporosis and fragility fracture diagnoses. Patients should be encouraged to access reputable sites, including sites displaying a HON seal. Academic and medical specialty societies demonstrate opportunity for improvement of their own websites and might be able to lead efforts to increase accessibility of high-quality content.
