Current Management of Acute and Posttraumatic Critical Bone Defects.

SUMMARY: Limb reconstruction in patients with critical-sized bone defects remains a challenge due to the availability of various technically demanding treatment options and a lack of standardized decision algorithms. Although no consensus exists, it is apparent from the literature that the combination of patient, surgeon, and institutional collaborations is effective in providing the most efficient care pathway for these patients. Success relies on choosing a particular surgical approach that manages infection, soft tissue defects, stability, and alignment. Recent systematic reviews demonstrate high success rates with the following management options: Ilizarov bone transport, Masquelet (induced membrane) technique, cancellous bone grafting, and vascularized bone grafts.

Racial/Ethnic and Gender Diversity of Orthopaedic Journal Editorial Boards.

BACKGROUND: In the current era of evidence-based medicine, scientific publications play a crucial role in guiding patient care. While the lack of diversity among orthopaedic surgeons has been well documented, little is known about the diversity of orthopaedic journal editorial boards. The purpose of this study was to assess the racial/ethnic and gender diversity of U.S. orthopaedic journal editorial boards. METHODS: The editorial boards of 13 orthopaedic journals were examined, including 10 subspecialty and 3 general orthopaedic journals. Race/ethnicity and gender were determined for each editorial board member. The representation observed on orthopaedic journal editorial boards was compared with representation at other phases of the orthopaedic pipeline, as well as within the various subspecialty fields of orthopaedics. Logistic regression and t tests were used to evaluate these comparisons. RESULTS: We identified 876 editorial board members of the 13 journals; 14.0% were Asian, 1.9% were Black, 1.9% were Hispanic, 2.4% were multiracial/other, and 79.7% were White. Racial/ethnic representation was similar across the subspecialty fields of orthopaedics (p > 0.05). The representation of women on orthopaedic editorial boards was 7.9%, with differences in gender diversity observed across subspecialty fields (p < 0.05). Among journals in the subspecialty fields of spine and trauma, female editorial board representation was lower than expected, even after taking into account the representation of women in these subspecialty fields (2.0% versus 9.0% [p = 0.002] and 3.8% versus 10.0% [p = 0.03], respectively). CONCLUSIONS: In this study of 13 subspecialty and general orthopaedic journals, the representation of racial/ethnic minorities and women on editorial boards was similar to their representation in academic orthopaedics. However, these values remain low in comparison with the population of patients treated by orthopaedic surgeons. Given the importance of scientific publications in the current era of evidence-based medicine, orthopaedic journals should continue working to diversify the membership of their editorial boards.

Axial Plane Deformity: How to Avoid It and How to Correct It.

Malreductions in the axial plane (ie, length and rotation) are common when managing long bone fractures. Careful attention to detail during the initial treatment can prevent these malreductions. Various fluoroscopy-based techniques exist for the prevention of malrotation and limb-length discrepancy during surgery for fracture. If malreductions do occur, a systematic clinical and radiographic evaluation can provide the necessary information to correct rotational malreduction and limb-length discrepancy.

Expedited surgery does not increase transfusion rates for patients with geriatric hip fracture taking factor Xa inhibitors.

Objectives: Geriatric patients who sustain hip fractures and are taking factor Xa inhibitors (Xa-I) experience surgical delay. Our institution developed a pharmacokinetic protocol to formally guide and expedite surgical timing for these patients. The protocol is based on the patient's renal function and timing of last Xa-I dose. For patients with impaired renal function, longer wait times are recommended. The purpose of this study was to determine the effects of this protocol for patients with geriatric hip fracture taking Xa-I. Design: Retrospective cohort study. Setting: Level 1 trauma center. Patients/Participants: A total of 164 patients aged 65 and older who were taking Xa-I before admission and underwent hip fracture surgery; 68 patients in the Standard group (2014-2018) and 96 patients in the Expedited group (2020-2022, after protocol implementation). Intervention: Hip fracture surgery. Main Outcome Measurements: Time to surgery (TTS), transfusion rate, blood loss, 90-day complication rates. Results: The median TTS was significantly shorter in the Expedited group (28.6 hours, interquartile range 21.3 hours) than in the Standard group (44.8 hours, interquartile range 21.1 hours) (P < .001). There were no differences in overall transfusion rates. Multivariable regression analysis demonstrated that time to surgery was not predictive of transfusion rate in all patients (OR 1.00, 95% CI 0.99-1.02, P = .652). There were no differences in blood loss or rates of 90-day complications. Conclusion: Geriatric patients with hip fractures and taking factor Xa inhibitors may warrant earlier surgery without an increased risk of transfusion or bleeding. Level of Evidence: Therapeutic Level III.

Increased Duration and Frequency of Lateral C-Arm Draping Does Not Increase Contamination Rates.

This study sought to quantify the rate of culture-positive drape contamination with varying degrees of drape manipulation for intra-operative fluoroscopic imaging. In this prospective cohort study, 30 patients with operatively closed lower extremity fractures were evaluated. The clip-drape technique was employed to cover the emitter. Swab samples were collected for bacterial growth. A t-test was applied for statistical comparison. Three of 30 cases (10% of operations) showed evidence of contamination. There was no statistically significant difference between duration of drape use or the amount of drape manipulations. None of the 30 patients in this study developed surgical site infection 90-days post-surgery. The clip drape technique for lateral fluoroscopy appears to be effective in maintaining surgical field sterility. Moreover, the number of drape manipulations and length of time the drape was in use was not related to drape contamination. Level of Evidence: Therapeutic Level II. (Journal of Surgical Orthopaedic Advances 32(2):107-110, 2023).

Orthopaedic Advances: Use of Three-Dimensional Metallic Implants for Reconstruction of Critical Bone Defects After Trauma.

Multiple successful strategies exist for the management of critical-sized bone defects. Depending on the location and etiology of an osseous defect, there are nuances that must be considered by the treating surgeon. The induced membrane technique and various modifications of the Ilizarov method (bone transport by distraction osteogenesis) have been the most common methods for biologic reconstruction. Despite the versatility and high union rates reported, they may not be practical for every patient. The rapid expansion of three-dimensional printing of medical devices has led to an increase in their use within orthopaedic surgery, specifically in the definitive treatment of critical bone defects. This article proposes indications and contraindications for implementation of this technology and reviews the available clinical evidence on the use of custom nonresorbable implants for the treatment of traumatic bone loss. Clinical cases are presented to illustrate the scenarios in which this approach is viable.

How do surgeons decide when to treat proximal humerus fractures with operative versus nonoperative management?

PURPOSE: The objective of this study was to determine the underlying factors that drive the decision for surgeons to pursue operative versus nonoperative management for proximal humerus fractures (PHF) and if fellowship training had an impact on these decisions. METHODS: An electronic survey was distributed to members of the Orthopaedic Trauma Association and the American Shoulder and Elbow Surgeons Society to assess differences in patient selection for operative versus nonoperative management of PHF. Descriptive statistics were reported for all respondents. RESULTS: A total of 250 fellowship trained Orthopaedic Surgeons responded to the online survey. A greater proportion of trauma surgeons preferred nonoperative management for displaced PHF fractures in patients over the age of 70. Operative management was preferred for older patients with fracture dislocations (98%), limited humeral head bone subchondral bone (78%), and intraarticular head split (79%). Similar proportions of trauma surgeons and shoulder surgeons cited that acquiring a CT was crucial to distinguish between operative and nonoperative management. CONCLUSION: We found that surgeons base their decisions on when to operate primarily on patient's comorbidities, age, and the amount of fracture displacement when treating younger patients. Further, we found a greater proportion of trauma surgeons elected to proceed with nonoperative management in patients older than the age of 70 years old as compared to shoulder surgeons.

Racial and Sex Disparities in Resident Attrition in Orthopaedic Surgery.

Studies have suggested that female individuals and individuals from backgrounds under-represented in medicine (URiM) are at increased risk of attrition during residency. This likely exacerbates the lack of diversity in our field. The aims of this study were to (1) characterize demographic composition in orthopaedic residency from 2001 to 2018 and (2) determine the race/ethnicity and identify any disparities. Methods: Demographic and attrition data from 2001 to 2018 were obtained from the Association of American Medical Colleges. Attrition data comprised the following categories: withdrawals, dismissals, and transfers to another specialty. Analysis compared demographic composition and determined attrition rates with subgroup analysis by race/ethnicity and sex. Results: From 2001 to 2018, female orthopaedic residents increased from 8.77% to 15.54% and URiM residents from 9.49% to 11.32%. The overall and unintended attrition rates in orthopaedic surgery were 3.20% and 1.15%, respectively. Among female residents, the overall and unintended attrition rates were 5.96% and 2.09% compared with 2.79% and 1.01%, respectively, in male residents. URiM residents had overall and unintended attrition rates of 6.16% and 3.11% compared with 2.71% and 0.83%, respectively, for their White counterparts. Black/African American residents had an attrition rate of nearly 10%. Female residents averaged 12.9% of all residents but 24% of those leaving orthopaedics. URiM residents were 10.14% of all residents but 19.51% of those experiencing attrition. In logistic regression models, female residents had a relative risk (RR) of 2.20 (p < 0.001) for experiencing all-cause attrition and 2.09 (p < 0.001) for unintended attrition compared with male residents. Compared with their White male counterparts, URiM residents had a RR for overall and unintended attrition of 2.36 and 3.84 (p < 0.001), respectively; Black/African American residents had a RR for the same of 3.80 and 7.20 (p < 0.001), respectively. Conclusion: Although female resident percentage has increased, orthopaedics continues to train fewer female surgeons than all other fields. Female and URiM residents in orthopaedic surgery are disproportionately affected by attrition. While recruitment has been the primary focus of diversity, equity, and inclusion efforts, this study suggests that resident retention through appropriately supporting residents during training is equally critical.

Optimizing the Entry Point for Reconstruction Nailing of the Femur.

INTRODUCTION: Varus after antegrade medullary nailing of the proximal femur is associated with worse outcomes. Anecdotally, a more medialized "trochiformis" entry is beneficial to avoid varus with valgus-bend (greater trochanteric entry) femoral nails. However, the optimal entry point remains unknown. The purpose of this study was to define the optimal entry point for reconstruction nailing. METHODS: Using standing alignment radiographs from 51 patients, we templated the ideal entry point for straight and valgus-bend nails from three major manufacturers using TraumaCad software. We measured the distance from the tip of the trochanter to the ideal entry site for each nail. We compared piriformis (PF) with trochanteric (GT) entry for each company and across manufacturers. RESULTS: The mean greater trochanter offset from the femoral axis was 15.2 mm. The mean PF entry was 5.9 to 6.7 mm medial to the mean GT entry for each company's nail and was statistically distinct. No differences were observed in GT and PF entry points across manufacturers. Only 2 of 153 ideal GT entry points were lateral to the tip of the trochanter. An increased neck-shaft angle (NSA) and increased GT offset were correlated with a more medial ideal entry point. DISCUSSION: The ideal entry point for GT nails is similar across manufacturers and is medial to the tip of the greater trochanter; however, PF and GT entry sites remain distinct. During preoperative planning and when executing femoral nailing intraoperatively, it may also be important to consider the NSA and GT offset of a patient before committing to a certain entry point.

Racial and Sex Disparities in Resident Attrition Among Surgical Subspecialties.

Importance: Racial and sex disparities are prevalent in surgical trainees. Although retrospective studies on resident attrition have been conducted for individual specialties, this study analyzes racial and sex differences in resident attrition among all surgical subspecialties over an 18-year period. Objective: To evaluate the racial and sex differences in resident attrition among surgical specialties over an 18-year period. Design, Setting, and Participants: This was a large, cross-sectional, database study that analyzed program-reported resident censuses (program information, resident demographics, and attrition status) obtained by the Association of American Medical Colleges from 2001 to 2018 for trainees in surgical residency programs. Data were analyzed from March 20, 2021, to June 8, 2022. Main Outcomes and Measures: Demographic trends (including race and ethnicity and sex) for all surgical subspecialty training programs over an 18-year period. Resident attrition includes all-cause withdrawals, dismissals, and transfers to another specialty. Unintended attrition encompasses all withdrawals, dismissals, and transfers except for changing career plans. Results: This study included 407 461 program-reported resident years collected from 112 205 individual surgical residents (67 351 male individuals [60.0%]). The mean percentage of female trainees was 40.0% (44 835) and increased over the study period. Sex disparity remained greatest in orthopedic surgery. Residents who were underrepresented in medicine (URiM) comprised 14.9% (16 695) of all surgical trainees but demonstrated a 2.1% decrease over the study period. Overall attrition rate among all specialties was 6.9% (7759), with an unintended attrition rate of 2.3% (2556). Female residents had a significantly higher relative risk (RR) of attrition (RR, 1.16; 95% CI, 1.11-1.22; P < .001) and unintended attrition (RR, 1.17; 95% CI, 1.08-1.26; P < .001) compared with their male counterparts. URiM residents were at significantly higher RR for attrition (RR, 1.40; 95% CI, 1.32-1.48; P < .001) and unintended attrition (RR, 1.92; 95% CI, 1.75-2.11; P < .001) compared with non-URiM residents. The highest attrition (10.6% [746 of 7043]) and unintended attrition (5.2% [367 of 7043]) rates were in Black/African American residents. The lowest attrition and unintended attrition rates were seen in White residents at 6.2% (4300 of 69 323) and 1.8% (1234 of 69 323), respectively. Black/African American residents were at disproportionate risk for attrition (RR, 1.66; 95% CI, 1.53-1.80; P < .001) and unintended attrition (RR, 2.59; 95% CI, 2.31-2.90; P < .001) compared with all other residents. Orthopedic surgery had the highest attrition (RR, 3.80; 95% CI, 2.84-5.09; P < .001) and unintended attrition (RR, 7.20; 95% CI, 4.84-10.71; P < .001) for Black/African American residents. Conclusions and Relevance: Results of this cross-sectional study suggest that the percentage of female residents in surgical specialties has improved over the last 18 years, and the percentage of URiM residents has remained relatively unchanged. Risk for attrition and unintended attrition was significantly elevated for female and URiM residents, specifically Black/African Americans. These results highlight current racial and sex disparities in resident attrition and demonstrate the importance of developing strategies to recruit, retain, and support residents.

Characterizing Single-star Negative Online Reviews of Orthopaedic Trauma Association Members.

INTRODUCTION: The purpose of this study was to characterize factors that contribute to 1-star negative reviews regarding orthopaedic trauma surgeons. METHODS: A search was done for Orthopaedic Trauma Association members on Yelp.com , Healthgrade.com , and Vitals.com in New York, Boston, San Francisco, Los Angeles, Dallas, Phoenix, Seattle, Baltimore, Denver, Houston, Philadelphia, and Washington, DC. All single-star reviews (out of a possible 5 stars) were included in this study. Reviews were categorized as either clinical or nonclinical and then further subcategorized. Categorical variables were analyzed using a chi-square test. The rate ratio (the ratio of the rate for nonsurgical divided by surgical reviews) was determined for each category. RESULTS: Two hundred eighty-eight single-star reviews were included in the study, comprising 655 total complaints. Of all complaints, 274 (41.8%) were clinically related and 381 (58.2%) were nonclinical. Of the 288 single-star reviews, 96 (33.3%) were from surgically treated patients and 192 (66.7%) were from nonsurgical patients. Most complaints were in reference to nonclinical aspects of care such as physician bedside manner (173 reviews, 60%), not enough time spent with provider (58 reviews, 20%), and wait time (42 complaints, 15%). The most common clinical complaints were for complication (61 reviews, 21%), disagree with decision/plan (49 reviews, 17%), and uncontrolled pain (45 reviews, 16%). Surgical patients had a significantly higher rate of clinical complaints than nonsurgical patients (1.57 vs. 0.64 clinical complaints per review, P < 0.001). Nonsurgical patients had a significantly higher rate of nonclinical complaints than surgical patients (1.43 vs. 1.10 nonclinical complaints per review, P < 0.001). DISCUSSION: Most 1-star reviews referenced a nonclinical aspect of care with a physician's bedside manner being the most common complaint. Surgical patients were markedly more likely to reference a clinical aspect of care, such as complications or misdiagnosis compared with nonsurgical patients, who more commonly referenced nonclinical aspects of care.

Chronic Warfarin Anticoagulation in Hip Fracture Patients Delays Surgery and Is Associated With Increased Risk of Postoperative Complications: A Multicenter Propensity-Score-Matched Analysis.

OBJECTIVE: To evaluate the effect of warfarin on blood transfusion and postoperative complications in a low-energy hip fracture population compared with a non-anticoagulated comparison group. DESIGN: Multicenter Retrospective Cohort. SETTING: Three Urban Level I Academic Trauma Centers. PATIENTS: Acute, low-energy, native hip fractures in patients 55 years of age or older on chronic warfarin anticoagulation, propensity score matched 1:2 to non-anticoagulated hip fracture patients meeting all other inclusion criteria. MAIN OUTCOME MEASUREMENTS: Transfusion and postoperative complication rates. RESULTS: Two hundred ten anticoagulated hip fracture patients were matched to 420 nonanticoagulated patients. A higher proportion of patients required blood transfusion in the warfarin cohort (52.4% vs. 43.3%, P < 0.001), attributable mostly to the subgroup of patients undergoing arthroplasty. Warfarin patients had higher incidence of overall 90-day complications (47% vs. 38%, P = 0.039) and readmissions (31.4% vs. 8.9%, P < 0.001). Day of surgery international normalized ratio (INR) did not influence transfusions or complications among warfarin patients. Warfarin patients undergoing surgery within 24 hours had no difference in transfusions and had fewer complications compared with those undergoing surgery after 24 hours. On multivariable logistic regression analysis, warfarin use and day of surgery INR were not predictors of transfusion or complications. CONCLUSIONS: Patients on warfarin experienced longer time to surgery and higher incidence of overall transfusion and postoperative complications within 90 days of surgery. However, warfarin use and day of surgery INR was not independently associated with transfusions or complications. The reason for poorer outcomes in warfarin patients remains a topic of further investigation. LEVEL OF EVIDENCE: Therapeutic Level III.

Trust but Verify: Discordance in Opioid Reporting Between the Electronic Medical Record and a Statewide Database.

INTRODUCTION: The electronic medical record (EMR) is often used as the primary source for patient medication lists and history. We sought to determine the accuracy of the EMR in documenting opioid prescriptions in patients undergoing fracture repair compared to a statewide database. METHODS: This retrospective study was conducted at an urban level 1 trauma center. Patients > 18 years old were included if they were admitted directly through the emergency room with isolated single orthopedic injuries. Opioid use and prescription data prior to admission and three months following surgery were collected through the EMR and a California statewide database of controlled substance prescriptions. A 2 x 2 McNemar's test was used to identify discordance between the EMR and Controlled Substance Utilization Review and Evaluation System (CURES). RESULTS: A total of 369 patients were included. The EMR reported that 143 patients had an opioid prescription within 30 days prior to admission compared to 75 patients reported by CURES (discordance rate [DR]: 34.7%) (p < 0.001). Between postoperative days (POD) 0-30, the EMR reported that 367 patients had an opioid prescription compared to 285 reported by CURES (DR: 22.8%) (p < 0.001). Between POD 30-60, the EMR reported that 142 patients had an opioid prescription compared to 84 reported by CURES (DR: 34.7%) (p < 0.001). Between POD 60-90, the EMR reported that 83 patients had an active opioid prescription compared to 60 patients reported by CURES (DR: 41.0%) (p = 0.10). CONCLUSION: There is a significant discordance between the databases in documenting opioid use. Physicians should check multiple sources to best assess active opioid prescriptions.

Survey Analysis of Orthopedic Call Compensation.

We sought to determine the type, frequency, and compensation details of orthopedic call for orthopedic traumatologists. We administered a 24-question survey to all members of the Orthopaedic Trauma Association regarding the number and type of orthopedic surgeons within the call pool, frequency of call, number of hospitals covered, and compensation for weekday, weekend, holiday, and pediatric calls. A total of 105 orthopedic surgeons replied. The most common number of physicians in the call pool was 6 to 10 (42.9%), whereas the most common number of traumatologists was 0 to 5 (90.5%), with 71.4% taking call at 1 hospital. Further, 56.7% were paid separately for weekday trauma call, with the most common number of call days per week being 2. The most common compensation was $1001 to $1500 (31.6%). For weekend call, 49.5% of physicians were paid separately, with the most common number of weekends on call per year being 11 to 15 (34.3% of replies). For pediatric call, 54.3% of physicians took call, with 28.6% paid separately and 33.3% receiving $0 to $500. For holiday call, 40.2% of physicians were paid separately, with 30.8% receiving $1001 to $1500. We describe the characteristics of traumatology call. Approximately 50% of physicians (range, 28.6%-56.3%) are compensated separately for taking different forms of call (ie, weekday, weekend, holiday). [Orthopedics. 2022;45(5):293-296.].

Understanding postoperative rehabilitation preferences in operatively managed proximal humerus fractures: do trauma and shoulder surgeons differ?

BACKGROUND: Proximal humerus fractures (PHFs) are common, and their incidence is increasing as the population ages. Despite this, postoperative rehabilitation remains unstandardized and little is known about surgeon preferences. The aim of this study was to assess differences in postoperative rehabilitation preferences and patient education between orthopedic trauma and shoulder surgeons. METHODS: An electronic survey was distributed to members of the Orthopaedic Trauma Association and the American Shoulder and Elbow Surgeons to assess differences in postoperative rehabilitation preferences and patient counseling. Descriptive statistics were reported for all respondents, trauma surgeons, and shoulder surgeons. Chi-square and unpaired 2-sample t tests were used to compare responses. Multinomial regression was used to further elucidate the influence of fellowship training independent of confounding characteristics. RESULTS: A total of 293 surgeons completed the survey, including 172 shoulder and 78 trauma surgeons. A greater proportion of trauma surgeons preferred an immediate weightbearing status after arthroplasty compared to shoulder surgeons (45% vs. 19%, P = .003), but not after open reduction and internal fixation (ORIF) (62% vs. 75%, P = .412). A greater proportion of shoulder surgeons preferred home exercise therapy taught by the physician or using a handout following reverse shoulder arthroplasty (RSA) (21% vs. 2%, P = .009). A greater proportion of trauma surgeons began passive range of motion (ROM) <2 weeks after 2-part fractures (70% vs. 41%, P < .001). Conversely, a greater proportion of shoulder surgeons began passive ROM between 2 and 6 weeks for 2-part (57% vs. 24%, P < .001) and 4-part fractures (65% vs. 43%, P = .020). On multinomial regression analysis, fellowship training in shoulder surgery was associated with preference for a nonweightbearing duration of >12 weeks vs. 6-12 weeks after ORIF. Similarly, fellowship training in shoulder surgery was associated with increased odds of preferring a nonweightbearing duration of <6 weeks vs. no restrictions and >12 weeks vs. 6-12 weeks after arthroplasty. Training in shoulder surgery was associated with greater odds of preferring a nonweightbearing duration prior to beginning passive ROM of 2-6 weeks vs. <2 weeks or >6 weeks for 2-part fractures, but not 4-part fractures. CONCLUSION: Trauma surgeons have a more aggressive approach to rehabilitation following operative PHF repair compared to shoulder surgeons regarding time to weightbearing status and passive ROM. Given the increasing incidence of PHFs and substantial variations in reported treatment outcomes, differences in rehabilitation after PHF treatment should be further evaluated to determine the role it may play in the outcomes of treatment studies.

Preoperative Transcutaneous Oxygen Perfusion Measurements in Predicting Atraumatic Wound Healing After Major Lower Extremity Amputation.

This study examined the correlation between preoperative transcutaneous oxygen perfusion (TcPO2) measurement and the success of wound healing after major lower extremity amputation. There is no validated consensus on how to accurately determine appropriate amputation levels. A TcPO2 greater than 30 to 40 mm Hg is widely cited as a positive predictor of postoperative wound healing, but its validity has not been well defined. A retrospective chart review was performed for patients who underwent above-knee amputation (AKA), through-knee amputation, or below-knee amputation (BKA) at a single institution from 2012 to 2018 with preoperative TcPO2 values and a minimum 30-day postoperative clinical follow-up. This review yielded 141 total amputations: 93 BKAs, 6 through-knee amputations, and 42 AKAs. Fifty-five amputations were unsuccessful, defined by postoperative wound dehiscence or infection. Of these, 37 were BKAs, 4 were through-knee amputations, and 14 were AKAs. There was a significant difference in preoperative TcPO2 between the successful and unsuccessful amputations, at 46.2 and 38.3 mm Hg, respectively (P=.02). A TcPO2 of 30 to 40 mm Hg showed a 68.8% success rate, and a TcPO2 of less than 20 mm Hg showed an 18.2% success rate. A receiver operating characteristic curve for TcPO2 predicting amputation success had an area under the curve of 0.53 for AKAs and 0.61 for BKAs; the diagnostic ability is far from prognostic. There is no linear association between TcPO2 and success rate. A TcPO2 of less than 20 mm Hg has a high positive predictive value for failure, but higher levels are not 100% predictive of wound healing success after amputation, as previously reported. [Orthopedics. 2022;45(3):174-180.].

Factors influencing surgical management of proximal humerus fractures: do shoulder and trauma surgeons differ?

BACKGROUND: Proximal humerus fractures (PHFs) are managed with open reduction and internal fixation (ORIF), hemiarthroplasty (HA), reverse shoulder arthroplasty (RSA), or nonoperatively. Given the mixed results in the literature, the optimal treatment is unclear to surgeons. The purpose of this study was to survey orthopedic shoulder and trauma surgeons to identify the patient- and fracture-related characteristics that influence surgical decision-making. METHODS: We distributed a 23-question closed-response email survey to members of the American Shoulder and Elbow Surgeons and Orthopaedic Trauma Association. Questions posed to respondents included demographics, surgical planning, indications for ORIF and arthroplasty, and the use of surgical augmentation with ORIF. Numerical and multiple-choice responses were compared between shoulder and trauma surgeons using unpaired t-tests and χ2 tests, respectively. RESULTS: Respondents included 172 shoulder and 78 trauma surgeons. When surgery is indicated, most shoulder and trauma surgeons treat 2-part (69%) and 3-part (53%) PHFs with ORIF. Indications for managing PHFs with arthroplasty instead of ORIF include an intra-articular fracture (82%), bone quality (76%), age (72%), and previous rotator cuff dysfunction (70%). In patients older than 50 years, 90% of respondents cited a head-split fracture as an indication for arthroplasty. Both shoulder and trauma surgeons preferred RSA for treating PHFs presenting with a head-split fracture in an elderly patient (94%), pre-existing rotator cuff tear (84%), and pre-existing glenohumeral arthritis with an intact cuff (75%). Similarly, both groups preferred ORIF for PHFs in young patients with a fracture dislocation (94%). In contrast, although most trauma surgeons preferred to manage PHFs in low functioning patients with a significantly displaced fracture or nonreconstructable injury nonoperatively (84% and 86%, respectively), shoulder surgeons preferred either RSA (44% and 46%, respectively) or nonoperative treatment (54% and 49%, respectively) (P < .001). Similarly, although trauma surgeons preferred to manage PHFs in young patients with a head-split fracture or limited humeral head subchondral bone with ORIF (98% and 87%, respectively), shoulder surgeons preferred either ORIF (54% and 62%, respectively) or HA (43% and 34%, respectively) (P < .001). CONCLUSIONS: ORIF and HA are preferred for treating simple PHFs in young patients with good bone quality or fracture dislocations, whereas RSA and nonoperative management are preferred for complex fractures in elderly patients with poor bone quality, rotator cuff dysfunction, or osteoarthritis. The preferred management differed between shoulder and trauma surgeons for half of the common PHF presentations, highlighting the need for future research.

Phosphaturic Mesenchymal Tumor-induced Osteomalacia Masquerading as an Orthopedic Polytrauma Patient: A Case Report and Review of the Literature.

Introduction: Phosphaturic mesenchymal tumor (PMT) is a rare benign tumor (500 cases to date) that can present in combination with a paraneoplastic syndrome called tumor-induced osteomalacia (TIO). To the best of our knowledge, it is the first case to date that presented as an orthopedic trauma patient. Case Report: This is a case of a 61-year-old male who initially presented as a polytrauma patient, but further investigation revealed a PMT causing TIO. This report describes his initial diagnosis and management from 2015 to 2021. Conclusion: TIO resultant of PMT may lead to severe bone pain, impending fractures, and delayed or misdiagnosis. This case demonstrates the importance of careful diagnosis and a team-based approach to managing PMT and its sequelae.

Delayed Surgery Does Not Reduce Transfusion Rates in Low-Energy Hip Fractures on Direct Oral Anticoagulants.

OBJECTIVES: To compare transfusion rates in patients on direct oral anticoagulants (DOACs) with nonanticoagulated patients undergoing hip fracture surgery and, secondarily, to determine whether time to surgery or complications differ between these groups. DESIGN: Multicenter retrospective cohort. SETTING: Three tertiary care, academic, Level I trauma centers. PATIENTS: Acute, operatively treated, low-energy hip fracture patients 55 years of age and older were included. Anticoagulated patients were matched in a 1:2 ratio to "control" nonanticoagulated hip fracture patients using propensity score matching. MAIN OUTCOME MEASUREMENTS: The primary outcome was incidence of perioperative transfusion. The secondary outcomes included time to surgery, length of stay, and 90-day complications, readmissions, reoperations, and mortality. RESULTS: One hundred thirty-two patients with hip fracture admitted on DOACs were identified (107 factor Xa inhibitors, 25 dabigatran) and were matched to 262 "control" nonanticoagulated patients. There was no difference in overall transfusion rates between anticoagulation and control groups (43.2%; n = 57 DOAC vs. 39.7%; n = 104 control; P = 0.517). The median time from admission to surgery was 41.7 hours in the DOAC group and 26.0 hours in the control group (P < 0.001). There were no differences in 90-day complication, readmission, reoperation, or mortality rates between DOAC and control groups. Comparing DOAC patients undergoing surgery within 24 hours and after 24 hours, there were no differences in transfusion rates (P = 0.558) or overall complication rates (P = 0.179). CONCLUSIONS: This study supports growing evidence that DOAC use should not be a determining factor in delaying surgery for patients with hip fracture who are otherwise medically optimized.
