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.

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.

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.

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.

Manual Stress Ankle Radiography Has Poor Ability to Predict Deep Deltoid Ligament Integrity in a Supination External Rotation Fracture Cohort.

Stress ankle radiographs are routinely performed to determine deep deltoid ligament integrity in supination external rotation (SER) ankle fractures. However, variability is present in the published data regarding what medial clear space (MCS) value constitutes a positive result. The purposes of the present study were to evaluate the diagnostic accuracy of different MCS cutoff values and determine whether this clinical test could accurately discriminate between patients with and without a deep deltoid ligament disruption. MCS measurements were recorded for stress ankle injury radiographs in an SER ankle fracture cohort. Preoperative ankle magnetic resonance imaging studies, obtained for all patients, were then read independently by 2 musculoskeletal attending radiologists to determine deep deltoid ligament integrity. The MCS measurements were compared with the magnetic resonance imaging diagnosis using receiver operating characteristic analyses to determine the sensitivity, specificity, and optimal data-driven cutoff values. SER II-III patients demonstrated a mean stress MCS distance of 4.3 ± 0.98 mm compared with 5.8 ± 1.76 mm in the SER IV cohort (p < .001). An analysis of differing MCS positive cutoff thresholds revealed that a stress MCS of 5.0 mm maximized the combined sensitivity and specificity of the external rotation test: 65.8% sensitive and 76.5% specific. Using the receiver operating characteristic curve analysis of the MCS measurement, the calculated area under the curve was 0.77, indicating inadequate discriminative ability for diagnosing SER pattern fractures with or without a deep deltoid ligament tear. Judicious use of additional diagnostic testing in patients with a stress MCS result between 4.0 mm and 5.5 mm is warranted.

Evaluation of Lauge-Hansen designation of Weber C fractures.

Associations between Weber C ankle fractures and pronation external rotation (PER) injuries of the Lauge-Hansen classification have often been incorrectly correlated. The purpose of the present study was to evaluate the Lauge-Hansen designation of Weber C fractures by establishing the proportion of Weber C fractures that are supination external rotation (SER), supination adduction (SA), pronation abduction (PA), PER, and hyperplantarflexion variant fractures. A clinical database of operative ankle fractures treated by the senior author (D.G.L.) was reviewed. The inclusion criteria were patient age older than 16 years, preoperative ankle radiographs, and Weber C fracture designation. A total of 132 patients met the inclusion criteria, and the proportion of PA, PER, SER, SA, and variant fractures among the Weber C fractures was analyzed. PA fractures accounted for 0.8% (n = 1), PER fractures 56.8% (n = 75), SER fractures 35.6% (n = 47), and hyperplantarflexion variant fractures 6.8% (n = 9) of the 132 Weber C fractures. Patients with Weber C-PER fractures were more commonly male (p = .005) and younger (p = .003) and demonstrated a greater fibular fracture height (p < .001) than those with Weber C-SER and Weber C-variant fractures. Our study quantitatively demonstrated that not all Weber C fractures occur secondary to pronation injuries. This distinction is important, because all pronation injuries will demonstrate medial ankle injury, but SER and variant fractures might not. We therefore recommend careful evaluation of the fibular fracture characteristics, including the direction of fracture propagation and the distance from the tibial plafond, when classifying Weber C fractures using the Lauge-Hansen system, because correct classification is vital in preparation for appropriate operative treatment.

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.

Complications following treatment of supination external rotation ankle fractures through the posterolateral approach.

BACKGROUND: The posterolateral approach to the ankle is a valuable approach for the treatment of ankle fractures (SER) ankle fractures. The purpose of this study was to determine the complication rate for ankle fractures treated through the posterolateral approach. We hypothesized that this approach would be associated with a low incidence of complications and good clinical outcomes. METHODS: A total of 112 patients with SER ankle fractures treated through a posterolateral approach met inclusion criteria. Prospectively collected data were examined retrospectively from chart review, preoperative plain radiographs, and MRI as well as postoperative radiographs. The mean age was 51.5 (range, 18 to 86) years. The primary outcome of the study was major (surgical debridement, flap, or split thickness skin graft) and minor (epidermolysis requiring local wound care) wound complications. The secondary outcomes included infection, symptomatic hardware, reoperation, loss of reduction, malreduction, nonunion, Foot and Ankle Outcome Scores, range of motion, and other perioperative complications. RESULTS: There were 11 minor wound related complications (9.8%) and 3 major wound complications (2.7%), 1 of which required a split thickness skin graft. The overall postoperative wound infection rate was 4.4% (5 of 112); 2 patients required hardware removal due to deep infection. Of patients, 7% (8 of 112) reported symptomatic lateral sided hardware and thus underwent removal of implants. The overall reoperation rate was 12.5%. The complication rate was 23%. No patients experienced loss of reduction. CONCLUSIONS: The posterolateral approach to the ankle was a valuable approach for SER ankle fractures. This series demonstrated many key aspects of this approach including access to the apex of the fibula fracture for posterior antiglide plating, access to the posterior malleolus for fixation, access to the posterior inferior tibiofibular ligament for repair, minimal major wound complications, good functional outcomes, and minimal need for reoperation.

Comparison of supination external rotation type IV ankle fractures in geriatric versus nongeriatric populations.

BACKGROUND: Geriatric patients' (defined as those older than 65 years old) inherent comorbidities, functional limitations, and bone quality present obstacles to successful clinical outcomes for operatively treated supination external rotation (SER) ankle fractures. We retrospectively reviewed a prospectively collected series of SER injuries between 2004 and 2010. This is a comparison of the radiographic and clinical outcomes of our geriatric (27 patients) and nongeriatric (81 patients) populations. We hypothesized that geriatric patients would have worse outcomes when compared to nongeriatric patients. METHODS: All SER ankle fractures (176) treated by a single surgeon were enrolled in a prospective database. All patients fulfilled inclusion criteria (108) consisting of 1 year of having clinical follow-up, postoperative radiographs, and Foot & Ankle Outcome Scores (FAOS). The primary outcome evaluated was functional outcome as exhibited by the FAOS. The secondary outcomes included adequacy of reduction, loss of reduction, postoperative complications (wound complications, infection, pain-driven hardware removal), and range of motion. RESULTS: Despite significantly higher rates of diabetes (P < .001) and peripheral vascular disease (P < .001), there were statistically significantly better FAOS outcomes in the symptoms subcategory among the geriatric population. There was no significant difference in the articular reduction, syndesmotic reduction, wound complications, postoperative infections, or range of motion between these groups. CONCLUSION: Geriatric patients exhibited equivalent complication rates, radiographic outcomes, and functional outcomes compared to nongeriatric patients in this series. Anatomic fixation and soft tissue management counter the inherent risks of operative intervention in geriatric populations that report higher rates of comorbidities. This study supports aggressive fracture- and ligament-specific operative intervention in geriatric patients presenting with unstable SER injuries.

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.

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.

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 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.

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.

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.].

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.

Patella Fractures: Approach to Treatment.

Patellar fracture morphology varies based on the mechanism of injury. Most fractures are either a result of direct impact or through an indirect eccentric extensor contraction injury. Each fracture pattern requires appropriate preoperative planning and individualization of the fixation method. Displaced fractures affect the extension apparatus, and often require surgical fixation. Surgical treatment is recommended in fractures with any of the following features: articular step-off > 2 mm, > 3 mm of fracture displacement, open fractures, and displaced fractures affecting the extensor mechanism. Meticulous handling of the soft-tissue envelope is of the utmost importance, given the patella's tenuous blood supply and limited soft-tissue envelope. Incongruent articular surface can result in detrimental long-term effects; therefore, surgical treatment is directed toward anatomic reduction and fixation. The evolution of patellar fracture fixation continues to maximize options to balance rigid fixation with low-profile fixation constructs. Improving functional outcomes, minimizing soft-tissue irritation, and limiting postoperative complications are possible by using the therapeutic principles of rigid anatomical fixation and meticulous soft-tissue handling.

COVID-19 Shelter-In-Place Orders Associated With Delayed Presentation and Deep Venous Thrombosis in Geriatric Hip Fractures.

Geriatric hip fractures benefit from timely surgery. At the onset of the corona-virus disease 2019 (COVID-19) pandemic, shelter-in-place (SIP) orders were mandated in high-risk cities. The authors hypothesized that geriatric patients with hip fractures were more likely to present to the hospital greater than 24 hours after injury during SIP orders. They retrospectively reviewed patients 65 years or older who presented with hip fractures between March 20, 2020, and May 24, 2020 (SIP group), and between March 20, 2019, and May 24, 2019 (historical group). Primary outcomes were incidence of presentation greater than 24 hours after injury and mean number of days between injury and presentation. Secondary outcomes were incidence of preoperative deep venous thrombosis (DVT) and 30- and 90-day mortality rates. Thirty-three patients comprised the SIP group, and 50 patients comprised the historical group. There were no significant differences in their demographics or medical comorbidities. The SIP group was more likely to present greater than 24 hours after injury (P=.05) and presented a greater number of days after injury (P=.02). There was a significant difference in the incidence of preoperative DVT (P=.03). There were no significant differences in 30- and 90-day mortality rates. Geriatric patients who sustained hip fractures during SIP restrictions for COVID-19 were more likely to present greater than 24 hours after injury, have a greater number of days between injury and presentation, and be diagnosed with a preoperative DVT.

Characterization of Infraspinatus Tendon Anatomy: The Soft-Tissue Portion of Remplissage.

PURPOSE: To characterize the morphology of the infraspinatus (IS) tendon and evaluate the bony anatomy of the humeral head (HH) to determine if there is a correlation between HH measurements and the amount of available IS tendon. METHODS: The superior-inferior width as well as the medial-lateral (M-L) length of the inferior and superior portions of the IS tendon were measured in 15 human cadaveric shoulders. Three measurements were then obtained for each corresponding humeral head: (1) anterior to posterior (A-P) distance, (2) midcoronal humeral head distance (MCHH), and (3) M-L distance. Pearson correlation coefficients (R) of tendon measurements relative to HH measurements were determined. RESULTS: The mean ± SD HH measurements were 44.3 ± 3.3 mm for A-P, 49.3 ± 3.4 mm at the MCHH, and 52.2 ± 3.4 mm in the M-L plane. The mean M-L length of the superior portion of the IS tendon was significantly different from the inferior portion (42.4 vs 31.0 mm, P < .0001). The mean ± SD width of the IS tendon was 19.4 ± 3.0mm. There was a statistically significant correlation (R = 0.58) between the M-L length of the superior IS tendon relative to the M-L HH distance (P < .05) and the A-P HH distance (P < .05). CONCLUSIONS: The superior M-L IS tendon length was significantly greater than the inferior M-L length. The M-L HH and the AP HH distances were significantly correlated to the M-L length of the superior portion of the IS tendon. These relationships may provide an estimation of the length of available IS tendon to help guide the management of Hill-Sachs lesions (HSLs). CLINICAL RELEVANCE: Knowledge of the available IS length can help optimize the management of HSLs following anterior shoulder dislocation. If IS tendon M-L length is less than HSL M-L length, then remplissage may result in capsulomyodesis rather than tenodesis. Placement of the superior anchor in a position that is as superior as possible within the HSL defect will maximize the opportunity for IS tenodesis.

Infraspinatus Tenotomy Improves Glenoid Visualization With the Modified Judet Approach.

OBJECTIVES: To determine if the addition of an infraspinatus tenotomy to the modified Judet approach (MJA) improves glenoid visualization. METHODS: We performed an MJA on 14 human cadaveric shoulders. After exposing the glenoid, the boundary of the visualized glenoid surface was marked with a 1.8- and 2.0-mm drill bit before and after performing an infraspinatus tenotomy, respectively. The humerus was disarticulated, and the pre- and post-tenotomy drill marks were verified. The area of the entire glenoid, and each of the 4 quadrants [anterior-superior (AS), anterior-inferior (AI), posterior-superior (PS), and posterior-inferior (PI)] were analyzed using a custom image-processing program. The amount of glenoid exposure and percentage of area visualized before and after the tenotomy were compared. RESULTS: Adding an infraspinatus tenotomy to the MJA significantly increased total glenoid area (cm) exposure by 33%, P < 0.0001. Three of 4 glenoid quadrants (PS, AS, and AI) had a significant increase in glenoid visualization, with the AS quadrant having the most substantial improvement after the tenotomy (+67%), P < 0.0001. CONCLUSIONS: The results provide the percentage of glenoid fossa that can be seen using an MJA and demonstrate that visualization significantly improves after adding an infraspinatus tenotomy.
