Frailty, length of stay and cost in hip fracture patients.

A hip fracture causes high morbidity and mortality. Frailty is associated with adverse outcomes and increased costs. Frailty measured using the Hospital Frailty Risk Score (HFRS) is associated with higher costs and adverse outcomes. HFRS is useful as a fuss-free frailty measurement in the management of older adults with hip fractures. INTRODUCTION: Hip fractures account for an increasing number of hospital admissions around the world and are associated with high rates of morbidity and mortality. Frailty is increasingly recognized to be associated with adverse outcomes and increased costs. The purpose of this study is to determine the association of the Hospital Frailty Risk Score (HFRS) with the healthcare cost and outcomes in older adults who present with a hip fracture. METHODS: A retrospective analysis was performed on 1014 patients ≥ 60 years who presented with a hip fracture between January 2016 to June 2020. Each patient was classified into HFRS low, intermediate or high frailty cohorts. Demographics, hip fracture type, comorbidities, Charlson Comorbidity Index (CCI), American Society of Anesthesiologist score (ASA), costs, length of stay, time to surgery, complications, readmission rate and mortality were compared between the cohorts. RESULTS: Median total hospitalization costs were significantly higher in the highest HFRS (SGD$22,432) patients as compared to intermediate (SGD$18,759) and low HFRS (SGD$15,671) patients. The difference between the high and low groups remains significant after adjusting for covariates using quantile regression. Similar results were shown for median length of stay (14 vs 10 vs 8 days), total number of complications (2 vs 1 vs 0) and adjusted time to surgery (p < 0.05). HFRS was not associated with 30-day readmission or 30-day or 1-year mortality. CONCLUSION: Frailty is associated with a marked increase in total costs in hip fracture patients. HFRS proved useful in estimating LOS and outcomes for older patients with hip fractures.

Delirium is significantly associated with hospital frailty risk score derived from administrative data.

OBJECTIVES: Delirium is highly prevalent in hospitalised older adults, under-diagnosed and associated with poor outcomes. We aim to determine (i) association of frailty measured using Hospital Frailty Risk Score (HFRS) with delirium, (ii) impact of delirium on mortality, 30-days readmission, extended length of stay (eLOS) and cost (eCOST). METHODS: Retrospective cohort study was conducted on 902 older adults ≥75 years discharged from an academic tertiary hospital between March and September 2021. Data was obtained from hospital administrative database. RESULTS: Delirium was prevalent in 39.1%, 58.1% were female with mean age 85.3 ± 6.2 years. Patients with delirium were significantly older, had higher HFRS, pneumonia, urinary tract infection (UTI), E.coli and Klebsiella infection, constipation, dehydration, stroke and intracranial bleed, with comorbidities including dementia, diabetes, hypertension, hyperlipidaemia and chronic kidney disease. In-hospital mortality, 30-days mortality, 30-days readmission, median LOS and cost was significantly higher. Delirium was significantly associated with at least intermediate frailty (OR = 3.52; CI = 2.48-4.98), dementia (OR = 2.39; CI = 1.61-3.54), UTI (OR = 1.95; CI = 1.29-2.95), constipation (OR = 2.49; CI = 1.43-4.33), Klebsiella infection (OR = 3.06; CI = 1.28-7.30), dehydration (OR = 2.01; CI = 1.40 - 2.88), 30-day mortality (OR = 2.52; CI = 1.42-4.47), 30-day readmission (OR = 2.18; CI = 1.36-3.48), eLOS (OR = 1.80; CI = 1.30-2.49) and eCOST (OR = 1.67; CI = 1.20-2.35). CONCLUSIONS: Delirium was highly prevalent in older inpatients, and associated with dementia, frailty, increased cost, LOS, 30-day readmissions and mortality. Hospital Frailty Risk Score had robust association with delirium and can be auto-populated from electronic medical records. Prospective studies are needed on multicomponent delirium preventive measures in high-risk groups identified by HFRS in acute care settings.

Should the location of distal tibial plating be influenced by the varus or valgus fracture pattern of tibial pilon fracture?

INTRODUCTION: Operative treatment of tibial pilon fracture is challenging. There is a lack of consensus and only one clinical study on the optimal location of distal tibial plating for fixation of pilon fractures based on varus or valgus fracture patterns. We hypothesize that complications rates, specifically mechanical complications, are not influenced by the location of the tibial plating in the fixation of pilon fractures with respect to varus or valgus fracture patterns. MATERIALS AND METHODS: Sixty-nine patients who had single plating for tibial pilon from 2007 to 2017 were recruited. They were divided into two groups, transverse fibular fracture (varus fracture pattern) and comminuted fibular fracture (valgus fracture pattern). Our primary outcome measure was any mechanical complications as a result of the location of plating (medial vs lateral) on varus or valgus fracture patterns. RESULTS: There were 38 (55.1%) patients with varus fracture pattern and 31 (44.9%) patients with valgus fracture pattern tibial pilon fractures. In the varus fracture pattern group, mechanical complications were not significantly different between the two plating locations (27.3 vs 33.3%, p > 0.05). Notably, there were more fibula fixations performed in patients with medial plating (74.1 vs 45.5%, p = 0.092) when compared those with lateral plating in the varus fracture pattern group. There were also no statistically significant differences found although 10 (40%) out of 25 patients had mechanical complications in the medial plating group compared to 1 (16.7%) out of 6 patients with lateral plating (p = 0.383) in the valgus fracture pattern group. CONCLUSION: There were no differences in mechanical complications for medial vs lateral plating in tibial pilon fracture based on varus or valgus deforming forces. As much as we should consider the fracture patterns and deforming forces when deciding on plating location, other factors such as careful soft tissue management and fragment-specific fixation should be prioritized.

Medications in COVID-19 patients: summarizing the current literature from an orthopaedic perspective.

PURPOSE: The review aims to provide a summary of the current literature regarding common medications prescribed in orthopaedic surgery and their potential implications in COVID-19 patients. METHODS: A systematic review was performed using the PRISMA guidelines. All clinical studies, reviews, consensus and guidelines related to the above medications and COVID-19 were included. RESULTS: A total of 18 articles were included. The use of analgesia, anti-inflammatories, steroids, anticoagulants, antibiotics, vitamin B, vitamin C and vitamin D and their potential impact on COVID-19 patients were reported. CONCLUSION: Eight main recommendations were derived from the review. Firstly, paracetamol remains the first line of analgesia and antipyretic. Secondly, there is no need to avoid NSAIDs for COVID-19 patients. Thirdly, opioids have the potential for immunosuppression in addition to respiratory depression and, therefore, should be prescribed with care in COVID-19 patients. Fourthly, patients with conditions where steroids are proven to be efficacious can continue to receive their steroids; otherwise, systemic steroids are not recommended for COVID-19 patients. Fifthly, orthopaedic surgeons following up on COVID-19 patients who are using steroids should continue to follow them up for possible avascular necrosis. Sixthly, whenever possible, oral anticoagulation should be converted to parental heparin. Seventhly, common orthopaedic antibiotics including penicillin and clindamycin are safe to continue for COVID-19 patients. However, for COVID-19 patients, the antibiotics can potentially be switched to macrolides and tetracyclines if the organisms are sensitive. Lastly, prescription for vitamins B, C and D should continue as per usual clinical practice.

Intraoperative periprosthetic femur fracture during bipolar hemiarthroplasty for displaced femoral neck fractures.

INTRODUCTION: We aim to review the incidence and risk factors for the development of intraoperative periprosthetic femur fractures while performing a bipolar hemiarthroplasty for displaced neck of femur fractures. Our secondary aim is to characterize the types of intraoperative periprosthetic fractures, the steps leading to the fractures, and the salvage treatments instituted. MATERIALS AND METHODS: 271 patients treated with bipolar hemiarthroplasty after traumatic displaced femoral neck fractures were retrospectively analyzed. Demographic data, co-morbidities, vitamin D level, consumption of steroids, ASA score, surgical approach, surgeon experience, use of cemented or uncemented implants, proximal femur morphology, and types of anaesthesia were analyzed statistically. RESULTS: There were 28 patients (10.3%) with intraoperative periprosthetic femur fractures. We found two significant independent risk factors which were the use of uncemented prosthesis (OR 4.15; 95% CI 1.65-10.46; p = 0.003) and Dorr type C proximal femurs (Dorr A OR 3.6; 95% CI 1.47-8.82; p = 0.005). In addition, patients with Dorr type C proximal femurs who underwent uncemented bipolar hemiarthroplasty were more likely to sustain an intraoperative periprosthetic fracture (14(73.7%) out of 19 patients; p = 0.002). There were no significant differences found in other risk factors. The most common location for these fractures was at the greater trochanter at 11 (39.3%) cases. Majority of them, 15 (53.6%), had intraoperative fractures during trial implant insertion and reduction. CONCLUSION: The overall incidence of intraoperative periprosthetic femur fractures during hemiarthroplasty for displaced neck of femur fractures was 10.3%. The incidence was significantly higher for uncemented (14.7%) when compared to cemented prosthesis (5.4%) and the greater trochanter was the commonest area for periprosthetic fractures during trial implant insertion and reduction. Uncemented prosthesis and Dorr type C proximal femurs were two significant independent risk factors contributing to intraoperative periprosthetic fractures. By identifying these risk factors, surgeons can take ample precautions to prevent complications.

Anatomic Basis for Minimally Invasive Flexor Hallucis Longus Transfer in Chronic Achilles Tendon Rupture.

The present cadaveric study was designed to measure the flexor hallucis longus (FHL) tendon length and obtain anatomic data regarding the graft-to-tunnel length ratio in an interference screw fixation model for the FHL short-harvest single-incision technique to the calcaneus. Ten fresh-frozen paired cadaveric specimens were used for the FHL short-harvest technique. The length of the osseous tunnel in the calcaneus was measured. At harvesting of the FHL tendon, the length of the tendon that traverses the osseous tunnel was measured with the ankle in neutral and maximal plantarflexion from the tip of the osseous tunnel to the transected end of the tendon within the bone tunnel. The mean length of the osseous tunnel was 42.7 ± 2.3 (range 38 to 46) mm. With the ankle in neutral position, the mean length of the FHL tendon traversing the bone tunnel was 31 ± 1.7 (range 29 to 34) mm. This mean length increased to 38.8 ± 1.6 (range 36 to 41) mm with the ankle placed in maximal plantarflexion. The ratio of the mean length of the tendon graft to the mean length of the osseous tunnel with the ankle in neutral was 0.727 ± 0.046 (range 0.667 to 0.81), and the ratio was 0.91 ± 0.042 (range 0.864 to 0.976) when the ankle was maximally plantarflexed. To the best of our knowledge, we report for the first time that the short-harvest technique provides >70% (ratio 0.727) of the FHL tendon graft in the osseous tunnel at all times, even when then ankle is in neutral, resulting in sufficient tendon length for FHL tendon transfer to the calcaneus for chronic Achilles tendon rupture.

Outcome of Patellar Tendon Versus 4-Strand Hamstring Tendon Autografts for Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis of Prospective Randomized Trials.

PURPOSE: To compare clinical outcomes of anterior cruciate ligament (ACL) reconstruction and investigate whether the clinical results of 4-strand hamstring tendon (HT) reconstruction are still inferior to that of the patellar tendon (PT). METHODS: We performed a comprehensive systematic review and meta-analysis of the English literature on PubMed, Scopus, Web of Science, and the Cochrane register for papers that compared clinical outcomes of PT versus HT for ACL reconstruction. Outcome measures analyzed included rate of rerupture, KT-1000, International Knee Documentation Committee grade, Lachman, pivot shift, Lysholm score, Tegner Activity Scale, anterior knee pain, and discomfort on kneeling. RESULTS: We included 19 studies from an initial 1,168 abstracts for the systematic review, and, eventually, 19 studies were included in the meta-analysis. The study population consisted of a total of 1784 patients. The average follow-up duration was 58.8 months. We found significant differences in favor of the HT technique in the domains of anterior knee pain, kneeling pain, and restriction in the range of active extension ("extension deficit"). We found no differences between the PT and HT technique in terms of rerupture rate. There were no clinically significant differences for the outcomes of Lysholm score and Tegner Activity Scale as well as the KT-1000 side-to-side at maximum manual force. CONCLUSIONS: Contemporary 4-strand HT ACL reconstruction is comparable with the PT technique in terms of clinical stability and postoperative functional status across most parameters studied. The HT technique carries lower risk of postoperative complications such as anterior knee pain, kneeling discomfort, and extension deficit. Primary ACL reconstruction using the 4-strand HT technique achieves clinical results that are comparable with the PT technique with significantly less postoperative complications. LEVEL OF EVIDENCE: Level I, systemic review and meta-analysis of Level I studies.

Functional outcome and mortality in nonagenarians following hip fracture surgery.

INTRODUCTION: The world's population is ageing and the elderly population itself is growing older. This population shows a high incidence of hip fractures. We performed a retrospective study, reviewing the functional status, postoperative complications and mortality rate of nonagenarians who underwent surgery for hip fracture. METHODS AND SUBJECTS: 56 nonagenarian patients underwent hip fracture surgery in our institution between January 2000 and December 2010. Two of these patients had presented with hip fracture on separate occasions, giving a total of 58 hips for analysis. Patients with open fracture, subtrochanteric fracture, polytrauma and pathological fracture were excluded. The case notes, electronic records and X-rays for all those included in the study were reviewed. The main outcome measures were functional status, postoperative complications and mortality rate at 1 year. RESULTS: Patients with extracapsular hip fractures were associated with higher risks of postoperative complications (60.7 %; p = 0.037), mortality (25 %; p = 0.003) and more likely to be non-ambulant at 1 year (53.6 vs 16.7 %; p = 0.003). Females were more likely to suffer postoperative complications than males (p = 0.016). 46.6 % of the patients had immediate postoperative complications and most commonly due to urological complications (29.3 %). The 1-year mortality rate was 12.1 %. A notable proportion of patients (65.5 %) remained ambulant 1 year postoperatively, although almost half of the patients (48.3 %) who could ambulate independently pre-injury required a walking aid after hip fracture surgery. CONCLUSION: Nonagenarians have good surgical outcomes after hip fracture surgery with low mortality rate. They should be treated similarly as their younger counterparts in terms of decision for surgery. Potential decline in functional status and rehabilitation options should be shared with the patient and family at an early stage.

Two-year outcomes of internal fixation with femoral neck system in patients with femoral neck fracture in an Asian population.

Background: Femoral neck fractures (FNF) are one of the most common fractures, with a projected increase in incidence with population growth and ageing. The Femoral Neck System (FNS) launched in 2019 was developed specifically for fixation of FNF with the purported advantages of providing both angular and rotational stability. We report our experience with the FNS and evaluate its effectiveness and associated complications. Methods: A retrospective case series of 50 patients who underwent surgical fixation for FNF from August 2020 to October 2021 using the FNS in two Singapore tertiary institutions with at least 2 years follow-up were included. Clinical data (patients' demographics, fracture classification, intra-operative and post-operative complications) were reviewed. Radiological analysis assessed the pre- and immediate post-operative garden alignment index (GAI) and presence of femoral neck shortening at 3 months. Results: The mean age was 63.5 years (SD 16.9, range 26-92). Five (10 %), 34 (68 %) and 11 (22 %) were ASA 1, 2 and 3 respectively. Twenty-four (48 %), 16 (32 %), 4 (8 %), and 6 (12 %) patients sustained Garden's 1, 2, 3 and 4 FNF respectively. The mean operative duration was 66.2 min (SD 20.5) and length of stay was 6.9 days (SD 4.6).The post-operative improvement in garden alignment index (GAI) was a mean of 9.1° (p < 0.001) on lateral view. The mean femoral neck shortening was 1.97 mm (SD 5.3) at 3 months. There were no intra-operative complications. Post-operatively, 1 (2 %) patient required blood transfusion, 1 (2 %) patient had implant cut-out and non-union managed non-operatively, 2 (4 %) patients developed avascular necrosis and required revision to total hip replacements. There were two (4 %) cases of 1-year mortality. Conclusion: The FNS achieved good outcomes with low rates of complications. The promising results justify its continued use and further evaluation in comparison to other devices.

A Scoping Review of Patient and Public Involvement (PPI) in Empirical Stroke Research.

BACKGROUND: Impactful, evidence-based solutions in surveillance, prevention, acute care, and rehabilitation for stroke survivors are required to address the high global burden of stroke. Patient and Public Involvement (PPI), where patients, their families, and the public are actively involved as research partners, enhances the relevance, credibility, and impact of stroke-related research. AIMS: This scoping review, adhering to the PRISMA Scoping Review guidelines, aims to identify and summarize how PPI is currently implemented and reported in empirical stroke research using a participatory approach. SUMMARY OF REVIEW: A comprehensive search strategy was developed and implemented across Medline, CINAHL, EMBASE, PsynchINFO and Cochrane electronic databases, supplemented by grey literature searches. Empirical stroke research papers in the English language, published from 2014 up to 2023 and documenting PPI activity were included. Of the 18,143 original papers identified, 2,824 full text manuscripts matching from this time window were screened. Only 2% (n=72) of these directly reported embedded PPI activity in empirical research. The majority were qualitative in design (60%) and were conducted in high-income countries (96%). Only one included study originated from a developing country, where the burden of stroke is highest. Most studies (94%) provided some information about the activities carried out with their PPI partners, mainly centered on the study design (57%) and management (64%), with only 4% of studies integrating PPI across all research cycle phases from funding application through to dissemination. When studies were examined for compliance with the Guidance for Reporting Involvement of Patients and the Public (GRIPP2) short form checklist, only 11% of included studies were 100% compliant. Twenty-one studies (29%) reported barriers and facilitators to including PPI in stroke research. Organization, authentic partnership and experienced PPI representatives were common facilitators and identified barriers reflected concerns around adequate funding, time required and diversity in perspectives. A positive reporting bias for PPI impact was observed, summarized as keeping the patient perspective central to the research process, improved care of study participants, validation of study findings, and improved communication / lay-summaries of complex research concepts. CONCLUSIONS: PPI is underutilised and inconsistently reported in current empirical stroke research. PPI must become more widely adopted, and notably in low- and middle-income countries. Consensus-driven standards for inclusion of PPI by funding organisations and publishers is required to support its widespread adoption.

The impact of value-driven outcomes initiative on endo-laparoscopic groin hernia repair.

PURPOSE: Value driven outcome (VDO) initiative is a value-based, patient-focused tool which utilizes a clinical outcome-based approach to optimize value of care based on clinically relevant quality indicators and costs required to achieve the care. In this study, we evaluate the impact of a VDO initiative on groin hernia repair, a commonly performed elective surgery in our hospital. METHODS: A VDO initiative was implemented in 2019 to encourage elective inguinal hernia repair to be performed at a day surgery setting. A comparison of outcomes was made between hernia surgeries performed in 2019 with those in 2020 and 2021. Pre-defined criteria were used to select patients that can be operated at a day surgery setting. Patients' expectations were addressed preoperatively about day surgery procedure and postoperative recovery. Day surgery bundles were used to standardize pre- and post-surgery protocols. Pain control was optimized using a specialized local anesthesia regime. RESULTS: A total of 263 laparoscopic hernia surgeries were performed between May 2019 and December 2021. After implementation of VDO initiative, the percentage of patients discharged within 24 h increased from 78% in year 2019 to 97% in year 2020 and 99% in year 2021. Conversion rate for day surgery to short stay decreased from 9% in year 2019 to 1% in year 2020 and 2% in year 2021. In 2019 to 2021, there were no 30-day readmission, no hernia recurrence in 90 days, no conversion to open surgery. CONCLUSION: VDO initiative is a promising tool to deliver better value-based care for patients undergoing endo-laparoscopic inguinal hernia repair.

Epidemiology and estimated economic impact of musculoskeletal injuries in polytrauma patients in a level one trauma centre in Singapore.

Introduction: Musculoskeletal injuries are the most common reason for surgical intervention in polytrauma patients. Methods: This is a retrospective cohort study of 560 polytrauma patients (injury severity score [ISS] >17) who suffered musculoskeletal injuries (ISS >2) from 2011 to 2015 in National University Hospital, Singapore. Results: 560 patients (444 [79.3%] male and 116 [20.7%] female) were identified. The mean age was 44 (range 3-90) years, with 45.4% aged 21-40 years. 39.3% of the patients were foreign migrant workers. Motorcyclists were involved in 63% of road traffic accidents. The mean length of hospital stay was 18.8 (range 0-273) days and the mean duration of intensive care unit (ICU) stay was 5.7 (range 0-253) days. Patient mortality rate was 19.8%. A Glasgow Coma Scale (GCS) score <12 and need for blood transfusion were predictive of patient mortality (p < 0.05); lower limb injuries, road traffic accidents, GCS score <8 and need for transfusion were predictive of extended hospital stay (p < 0.05); and reduced GCS score, need for blood transfusion and upper limb musculoskeletal injuries were predictive of extended ICU stay. Inpatient costs were significantly higher for foreign workers and greatly exceeded the minimum insurance coverage currently required. Conclusion: Musculoskeletal injuries in polytrauma remain a significant cause of morbidity and mortality, and occur predominantly in economically productive male patients injured in road traffic accidents and falls from height. Increasing insurance coverage for foreign workers in high-risk jobs should be evaluated.

Bicycle-Related Injuries of the Upper Extremity.

Background: In recent years, the increasing popularity of cycling for commuting and leisure has led to a corresponding increase in bicycle-related injuries. However, there is a lack of extensive analysis of bicycle-related injuries to the upper limb in the literature. Methods: A retrospective review of all patients with conventional bicycle-related injuries of the upper limb was performed. Data on demographics, mechanisms of injury, region of injury, fracture type, management type, and length of hospital stay were extracted and analyzed. Results: A total of 177 of 733(24%) patients with bicycle-related upper limb injuries were identified. The most common mechanism of injury was a collision with another vehicle (60%). Frequently affected regions were the shoulder (48%), hand (19%), and wrist (19%). Eighty-eight (50%) patients sustained bony injuries, while the remainder (50%) had isolated soft tissue injuries. Fifty-three (30%) patients required a mean of 3.9 days of hospitalization, whereas 13 (25%) patients required high dependency or intensive care unit treatment. Surgical interventions were required in 47 (27%) patients. Conclusion: Bicycle-related injuries to the upper limb are common and result in significant morbidity. The most common regions affected are the shoulder, wrist, and hand. Most of the injuries were caused by collisions with other vehicles. A third of affected patients required hospitalization, and a quarter required surgical intervention.

Outcomes of Care by Geriatricians and Non-geriatricians in an Academic Hospital.

Introduction: While hospitalist and internist inpatient care models dominate the landscape in many countries, geriatricians and internists are at the frontlines managing hospitalized older adults in countries such as Singapore and the United Kingdom. The primary aim of this study was to determine outcomes for older patients cared for by geriatricians compared with non-geriatrician-led care teams. Materials and Methods: A retrospective cohort study of 1,486 Internal Medicine patients aged ≥75 years admitted between April and September 2021 was conducted. They were either under geriatrician or non-geriatrician (internists or specialty physicians) care. Data on demographics, primary diagnosis, comorbidities, mortality, readmission rate, Hospital Frailty Risk Score (HFRS), Age-adjusted Charlson Comorbidity Index, Length of Stay (LOS), and cost of hospital stay were obtained from the hospital database and analyzed. Results: The mean age of patients was 84.0 ± 6.3 years, 860 (57.9%) females, 1,183 (79.6%) of Chinese ethnicity, and 902 (60.7%) under the care of geriatricians. Patients under geriatrician were significantly older and had a higher prevalence of frailty, dementia, and stroke, whereas patients under non-geriatrician had a higher prevalence of diabetes and hypertension. Delirium as the primary diagnosis was significantly higher among patients under geriatrician care. Geriatrician-led care model was associated with shorter LOS, lower cost, similar inpatient mortality, and 30-day readmission rates. LOS and cost were lower for patients under geriatrician care regardless of frailty status but significant only for low and intermediate frailty groups. Geriatrician-led care was associated with significantly lower extended hospital stay (OR 0.73; 95% CI 0.56-0.95) and extended cost (OR 0.69; 95% CI 0.54-0.95). Conclusion: Geriatrician-led care model showed shorter LOS, lower cost, and was associated with lower odds of extended LOS and cost.

Prevalence of carpal fracture in Singapore.

PURPOSE: To determine the prevalence of carpal fracture in Singapore, to compare demographic differences between isolated scaphoid and other carpal fractures, and to identify parameters associated with multiple carpal fractures. METHODS: A total of 149 patients with 162 carpal fractures seen at the National University Hospital in 2009 were enrolled into the study. We retrospectively reviewed their case records and radiographic studies. Pertinent demographic data including patient age, gender, occupation, injured wrist, dominant hand, mechanism of injury, and type of carpal fracture were then recorded and statistically analyzed. We also performed a separate analysis of isolated scaphoid versus other carpal fractures and single versus multiple carpal fractures. RESULTS: Patients with carpal fracture were predominantly male (132), below 40 years of age (116), and usually right hand dominant (136). The more common occupations were students (30), full-time military national servicemen (24), and construction workers (14). Most presented after a fall on an outstretched hand from standing height (81). The scaphoid was the most common single carpal fracture (99). This was followed by triquetrum (27), hamate (5), pisiform (4), lunate (2), capitate (1), and trapezium (1). No fracture of the trapezoid was encountered. Ten patients had multiple carpal fractures, of which 4 were perilunate fracture dislocations. The mean age and male/female ratio for isolated scaphoid and other carpal fractures was 26 years versus 41 years (p<.001) and 13:1 versus 4:1 (p=.036), respectively. A high-energy mechanism of injury was the only parameter associated with multiple carpal fractures (p=.009). CONCLUSIONS: The prevalence of carpal fracture in our population was consistent with studies performed in other countries. Military conscription was identified as an at-risk activity predisposing to carpal fracture. Isolated scaphoid and other carpal fractures exhibit different demographics in terms of age and gender, which may be related to differences in the mechanism of injury. A high-energy mechanism of injury was associated with multiple carpal fractures.

Definitive Surgery Is Safe in Borderline Patients Who Respond to Resuscitation.

OBJECTIVES: We hypothesize that in adequately resuscitated borderline polytrauma patients with long bone fractures (femur and tibia) or pelvic fractures, early (within 4 days) definitive stabilization (EDS) can be performed without an increase in postoperative ventilation and postoperative complications. DESIGN: Retrospective cohort study. SETTING: Level 1 trauma center. PATIENTS: In total, 103 patients were included in this study; of whom, 18 (17.5%) were female and 85 (82.5%) were male. These patients were borderline trauma patients who had the following parameters before definitive surgery, normal coagulation profile, lactate of <2.5 mmol/L, pH of ≥7.25, and base excess of ≥5.5. INTERVENTION: These patients were treated according to Early Total Care, definitive surgery on day of admission, or Damage Control Orthopaedics principles, temporizing external fixation followed by definitive surgery at a later date. Timing of definitive surgical fixation was recorded as EDS or late definitive surgical fixation (>4 days). MAIN OUTCOME MEASURES: Primary outcome measured was the duration of ventilation more than 3 days post definitive surgery and presence of postoperative complications. RESULTS: Thirty-five patients (34.0%) received Early Total Care, whereas 68 (66.0%) patients were treated with Damage Control Orthopaedics. In total, 51 (49.5%) of all patients had late definitive surgery, whereas 52 patients (50.5%) had EDS. On logistic regression, the following factors were found to be predictive of higher rates of postoperative ventilation ≥ 3 days, units of blood transfused, and time to definitive surgery > 4 days. Increased age, head abbreviated injury score of 3 or more and time to definitive surgery were found to be associated with an increased risk of postoperative complications. CONCLUSIONS: Borderline polytrauma patients with no severe soft tissue injuries, such as chest or head injuries, may be treated with EDS if adequately resuscitated with no increase in need for postoperative ventilation and complications. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Gustilo IIIB Open Tibial Fractures: An Analysis of Infection and Nonunion Rates.

BACKGROUND: Gustilo IIIB tibial fractures are associated with high rates of infection and nonunion. This study evaluates the impact of factors such as patient demographics, mechanism of injury, time to the first debridement, and time to flap coverage on the union and infection rates. MATERIALS AND METHODS: A retrospective analysis was performed on all patients with open tibial fractures who presented to our tertiary trauma center over 13 years from April 2000 to August 2013. All patients were followed for at least 6 months and continued till radiographic evidence of union (maximum 72 months). Time to fracture union was based on radiological evidence of callus bridging at least three cortices. Information on infection rates and the presence of microbes were evaluated. RESULTS: A total of 120 patients were analyzed. The mean time to fracture union was 33.8 weeks. Younger age was associated with a lower risk of nonunion with the mean age being 30.4 years in union group compared to 38.2 in the delayed-union group. Smoking was associated with an increased risk of delayed union with revision surgery being needed in 61.5% of smokers compared to 36.4% in nonsmokers. Rates of infection were high at 30.3%. Smoking was associated with an increased risk of infection (65.4% vs. 24.7%). CONCLUSION: High-energy open tibia fractures required an average of 8.5 months to heal and delayed or nonunion at an earlier juncture cannot be assumed.
