Retrograde intramedullary nailing of AO/OTA 33C femur fractures in patients with below-knee amputations: technical note and case series.

PURPOSE: Intra-articular distal femur fractures in patients with a lower extremity amputation can present a technical challenge for the treating surgeon in what may be otherwise considered a routine procedure in non-amputees. Difficulties with positioning, fracture reduction, limb contractures, and stump osteoporosis can present challenges with treatment. Here, we describe the surgical technique and outcome of a case series of amputee patients with AO/OTA 33C femur fractures. METHODS: Retrospective case series of five patients with a comminuted supracondylar distal femur fracture with intercondylar extension proximal to a below-knee amputation treated with retrograde intramedullary nail at a single Level 1 trauma center from January 1, 2021, to January 1, 2023. Baseline demographic and clinical data were recorded. Rate of bony union and complications were documented. RESULTS: Five patients (three females and two males) with a mean age of 48 years who were treated for a comminuted supracondylar distal femur fracture with intercondylar extension proximal to a below-knee amputation were identified. At the time of final follow-up (mean 109.3 days, range 29-183 days), all patients had healed their incisions and were progressing to return of function with their prosthesis. All patients were treated with the surgical technique described in this article, and no postoperative complications were reported. CONCLUSION: This is an effective and safe technique for surgical treatment of comminuted intra-articular distal femur fractures in patients with an ipsilateral below-knee amputation. We believe that this technique can be utilized by any orthopedic surgeon taking trauma call and can avoid unnecessary transfers or delays to care.

Multidimensional Fluoroscopy to Assess Closed Reduction in Displaced Young Femoral Neck Fractures: A Report of 3 Cases.

CASE: The authors present 3 physiologically young patients with displaced femoral neck fractures who underwent initial closed reduction and provisional fixation. Multidimensional fluoroscopy was used to assess fracture reduction before definitive fixation, with 1 patient requiring an open approach because of inadequate fracture reduction after closed attempts. CONCLUSION: Displaced femoral neck fractures in young patients remain difficult injuries to treat. Reduction quality is a significant predictor of patient outcomes. Intraoperative multidimensional fluoroscopy provides treating surgeons with a tool to assess fracture reduction after closed reduction maneuvers and allows for intraoperative treatment adjustment as needed.

Retrograde Intramedullary Nailing Versus Locked Plating for Extreme Distal Periprosthetic Femur Fractures: A Multicenter Retrospective Cohort Study.

OBJECTIVES: To compare clinical and radiographic outcomes after retrograde intramedullary nailing (rIMN) versus locked plating (LP) of "extreme distal" periprosthetic femur fractures, defined as those that contact or extend distal to the anterior flange. DESIGN: Retrospective review. SETTING: Eight academic level I trauma centers. PATIENT SELECTION CRITERIA: Adult patients with periprosthetic distal femur fractures at or distal to the anterior flange (OTA/AO 33B-C[VB1]) treated with rIMN or LP. OUTCOME MEASURES AND COMPARISONS: The primary outcome was reoperation to promote healing or to treat infection (reoperation for elective removal of symptomatic hardware was excluded from this analysis). Secondary outcomes included nonunion, delayed union, fixation failure, infection, overall reoperation rate, distal femoral alignment, and ambulatory status at final follow-up. Outcomes were compared between patients treated with rIMN or LP. RESULTS: Seventy-one patients treated with rIMN and 224 patients treated with LP were included. The rIMN group had fewer points of fixation in the distal segment (rIMN: 3.5 ± 1.1 vs. LP: 6.0 ± 1.1, P < 0.001) and more patients who were allowed to weight-bear as tolerated immediately postoperatively (rIMN: 45%; LP: 9%, P < 0.01). Reoperation to promote union and/or treat infection was 8% in the rIMN group and 16% in the LP group ( P = 0.122). There were no significant differences in nonunion ( P > 0.999), delayed union ( P = 0.079), fixation failure ( P > 0.999), infection ( P = 0.084), or overall reoperation rate ( P > 0.999). Significantly more patients in the rIMN group were ambulatory without assistive devices at final follow-up (rIMN: 35%, LP: 18%, P = 0.008). CONCLUSIONS: rIMN of extreme distal periprosthetic femur fractures has similar complication rates compared with LP, with a possible advantage of earlier return to weight-bearing. Surgeons can consider this treatment strategy in all fractures with stable implants and amenable prosthesis geometry, even extreme distal fractures. LEVEL OF EVIDENCE: Therapeutic Level III.

Use of 3D Fluoroscopy to Assist in the Reduction and Fixation of Pelvic and Acetabular Fractures: A Safety and Quality Case Series.

SUMMARY: Multidimensional fluoroscopy has been increasingly used in orthopaedic trauma to improve the intraoperative assessment of articular reductions and implant placement. Owing to the complex osteology of the pelvis, cross-sectional imaging is imperative for accurate evaluation of pelvic ring and acetabular injuries both preoperatively and intraoperatively. The continued development of fluoroscopic technology over the past decade has resulted in improved ease of intraoperative multidimensional fluoroscopy use in pelvic and acetabular surgery. This has provided orthopaedic trauma surgeons with a valuable tool to better evaluate reduction and fixation at different stages during operative treatment of these injuries. Specifically, intraoperative 3D fluoroscopy during treatment of acetabulum and pelvis injuries assists with guiding intraoperative decisions, assessing reductions, ensuring implant safety, and confirming appropriate fixation. We outline the useful aspects of this technology during pelvic and acetabular surgery and report its utility with a consecutive case series at a single institution. The added benefits of this technology have improved the ability to effectively manage patients with pelvis and acetabulum injuries.

High Nonunion and Amputations Rates With Either Early Intramedullary Nail Removal or Retention for Tibial Shaft Fracture-Related Infections.

OBJECTIVES: To compare debridement, antibiotics, and implant retention (DAIR) and intramedullary nail (IMN) removal with subsequent strategy for fracture stabilization in the treatment of tibia fracture-related infections (FRIs) occurring within 90 days of initial IMN placement. DESIGN: Retrospective case-control. SETTING: Four academic, Level 1 trauma centers. PATIENTS: Sixty-six patients who subsequently received unplanned operative treatment for FRI diagnosed within 90 days of initial tibia IMN. INTERVENTION: DAIR versus IMN removal pathways. MAIN OUTCOME MEASUREMENTS: Fracture union. RESULTS: Twenty-eight patients (42.4%) were treated with DAIR and 38 (57.6%) via IMN removal with subsequent strategy for fracture stabilization. Mean follow-up was 16.3 months. At final follow-up, ultimate bone healing was achieved in 75.8% (47/62), whereas 24.2% (15/62) had persistent nonunion or amputation. No significant difference was observed in ultimate bone healing ( P = 0.216) comparing DAIR and IMN removal. Factors associated with persistent nonunion or amputation were time from injury to initial IMN ( P < 0.001), McPherson systemic host grade B ( P = 0.046), and increasing open-fracture grade, with Gustilo-Anderson IIIB/IIIC fractures being the worst ( P = 0.009). Fewer surgeries after initial FRI treatment were positively associated with ultimate bone healing ( P = 0.029). CONCLUSIONS: Treatment of FRI within 90 days of tibial IMN with DAIR or IMN removal with subsequent strategy for fracture stabilization results in a high rate, nearly 1 in 4, of persistent nonunion or amputation, with neither appearing superior for improving bone healing outcomes. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Medialized Trochanteric Entry Nailing Is a Safe and Effective Method for High-Energy Subtrochanteric Femur Fracture Treatment.

Fixation of subtrochanteric femur fractures using intramedullary nails can provide high rates of osseous union. However, a lateral starting point or a medial trajectory can result in varus alignment, typically seen with trochanteric entry nails. Even with piriformis nails, medial comminution can result in secondary malalignment and varus. Varus can predictably result in nonunion and need for repeat operations. Medialized trochanteric entry nailing has been reported previously as a method to prevent varus alignment in low-energy, atypical subtrochanteric femur fractures in association with bisphosphonate use. We present a surgical technique using a medialized trochanteric nail entry point to provide proper alignment and avoidance of varus malreduction in 24 patients with a subtrochanteric femur fracture after a high-energy traumatic event.

The injury characteristics of open pilon fractures predictive of complications.

OBJECTIVE: Determine predictive injury factors for wound complications in open pilon fractures (OTA/AO 43B and 43C). DESIGN: Retrospective Case Series. SETTING: Level I Trauma Center. PATIENTS/PARTICIPANTS: A total of 61 open pilon fractures in 60 patients were evaluated after meeting inclusion and exclusion criteria. INTERVENTION: The majority of injuries underwent a staged protocol with immediate antibiotics, debridement, irrigation and external fixation. Following soft tissue stabilization, internal fixation was performed and wound closure achieved in a coordinated fashion depending on the type of closure required. MAIN OUTCOME MEASUREMENTS: Early amputation rate, 90-day major (wound dehiscence or deep infection requiring operative intervention) and minor (superficial infection) wound complications. RESULTS: Four patients incurred early amputations, 11 had major wound complications and 5 had minor wound complications. An early amputation was more likely if they presented with an OTA Open Fracture Classification (OTA-OFC) Bone Loss Grade 3. A major wound complication was more likely if they presented with a fall from > 3 m, a multifragmentary articular surface, a segmental fibula fracture, or an OTA-OFC Contamination Grade 3. A multifragmentary articular surface was also predictive of developing any wound complication. CONCLUSIONS: Open pilon fractures are severe, limb-threatening injuries and are at risk for wound complications. Patients presenting with these injuries and a predictive factor should be counseled regarding the possibility of early limb loss or experiencing a wound complication that will require additional treatment. LEVEL OF EVIDENCE: Level III.

The Impact of Magnetic Resonance Imaging on the Diagnosis of High-Energy Ipsilateral Femoral Neck and Shaft Fractures.

OBJECTIVE: To evaluate the most common femoral shaft fracture morphology associated with an ipsilateral femoral neck fracture in high-energy blunt trauma using magnetic resonance imaging (MRI). DESIGN: Retrospective review. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: 219 consecutive patients sustaining 228 femoral shaft fractures from high-energy blunt trauma. MAIN OUTCOME MEASUREMENTS: Fracture patterns were analyzed using the OTA/AO classification system. In addition, location of the fracture was measured as the distance from the distal aspect of the lesser trochanter to the center of the femoral shaft fracture. RESULTS: An OTA/AO 31 type fracture was seen in 16.5% (20/121) of patients presenting with OTA/AO 32-A type fractures, 12% (6/50) of patients with OTA/AO 32-B type fractures, and 26.3% (15/57) of patients with OTA/AO 32-C type fractures. The fractures that occurred in the middle or distal third of the femur shaft constituted 95.1% (39/41). CONCLUSIONS: In this cohort, patients with middle and distal third OTA/AO 32-C type fractures had the highest association with an ipsilateral OTA/AO 31 type fracture. OTA/AO 32-A2 and 32-A3 type fractures had the highest association with femoral neck fractures seen only on MRI. The data presented suggest continued usage of the rapid sequence pelvic MRI for all patients with high-energy femoral shaft fractures in whom a femoral neck fracture was not seen on an x-ray or a computed tomography scan. LEVEL OF EVIDENCE: Diagnostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Is retrograde nailing superior to lateral locked plating for complete articular distal femur fractures?

INTRODUCTION: Nonunion rates for distal femur fractures treated with lateral locked plating (LLP) remains as high as 18-22% despite significant advances with implant design and construct modulation. However, whether treatment of distal femur fractures with rIMN has improved outcomes compared to LLP has not been well characterized. The purpose of this study was to compare outcomes of complete articular distal femur fractures (AO/OTA 33-C) treated with either LLP or rIMN. METHODS: 106 distal femur fractures in 106 patients between January 2014 and January 2018 were identified. Medical records were reviewed to collect patient age, gender, body mass index, sagittal and coronal plane alignment on immediate postoperative radiographs, time to union, incidence of nonunion, and incidence of secondary operative procedures for repair of a nonunion. RESULTS: Of 106 patients, 50 underwent rIMN and 56 underwent LLP. The mean age at the time of injury was 51 years (21 to 86 years) and there were 55 males. Average coronal alignment of 83.7° of anatomic lateral distal femoral angle (aLDFA) and sagittal alignment of <1° of apex anterior angulation in the rIMN group. In the LLP group there was an average of 87.9° of aLDFA and 1.9° of apex anterior angulation (p = .005 and p = .36). Average time to union in the rIMN group was 6 months and 6.6 months in the LLP group (p = .52). Incidence of nonunion in the rIMN group was 11.8% and 27.5% in the LLP group (p = .008). There were 8 secondary procedures for nonunion in the rIMN group and 18 in the LLP group (p = .43). CONCLUSIONS: Our results demonstrated a higher nonunion rate and coronal plane malalignment with LLP compared to rIMN. While prospective data is required, rIMN does appear to be an appropriate treatment for complete articular distal femur fractures with a potentially decreased rate of nonunion .

The effects of locking inserts and overtorque on the mechanical properties of a large fragment locking compression plate.

PURPOSE: The study was to determine the effect of locking hole inserts and their insertion torque on the fatigue life of a large fragment Locking Compression Plate (LCP) under bending forces. METHODS: Fatigue strength of the LCP was examined using cyclic three-point bend testing at 80% yield strength of the construct. Locking hole inserts were used in 2, 4, and 6-hole of a 12-hole plate to simulate three different working lengths. Within each working length, plates were tested without locking inserts serving as the control group. In the experimental groups, inserts were tightened to manufacturer recommendations (4 Nm) and using overtorque (8 Nm). RESULTS: Significantly fewer cycles to failure were observed in control groups versus the locking hole insert groups for all working lengths (2-hole: 4 Nm p = 0.003, 8 Nm p = 0.003; 4-hole: 4 Nm p = 0.02, 8 Nm p < 0.001; 6-hole: 4 Nm p = 0.004, 8 Nm p < 0.001). There was a statistically significant increase in fatigue strength when using overtorque in the 4-hole (p = 0.04) and 6-hole (p = 0.01) defect groups. This was not shown in the 2-hole defect group (p = 0.99). CONCLUSIONS: By placing locking inserts in the empty locking regions of Combi holes along the working length, the number of cycles to failure was increased. Tightening inserts to twice the recommended insertion torque further increased cycles to failure in longer working length models. A longer fatigue life has the potential to decease the incidence of plate failure especially in the setting of delayed union due to poor intrinsic healing capacity, fractures in the geriatric population, osteoporosis and periprosthetic fractures.

Implementation of a novel MRI protocol for diagnosing femoral neck fractures in high energy femoral shaft fractures: One year results.

INTRODUCTION: Preliminary results using a novel rapid-sequence MRI to diagnose ipsilateral femoral neck fractures in patients sustaining high-energy femoral shaft fractures have been favorable compared to radiographic and CT imaging alone. To evaluate and optimize this new institutional imaging protocol further, we reviewed our results one year after implementation. METHODS: Rapid-sequence MRI was added to the imaging evaluation of patients with high-energy femoral shaft fractures without femoral neck fractures identified on radiographs or CT imaging. Data was retrospectively reviewed from a consecutive series of patients who met inclusion criteria. RESULTS: From September 2018 through September 2019, 114 patients sustained 121 high-energy femoral shaft fractures. The average patient age was 29.9 years, 73.7% (84/114) of patients were male, and 16.5% (20/121) were open fractures. Of patients indicated for a rapid-sequence MRI, 86% (92/107) underwent MR imaging. 5% (6/121) of patients had an ipsilateral femoral neck fracture identified on radiographs alone. Three additional femoral neck fractures were identified with CT imaging for an initial incidence of 7.4% (9/121). MRI identified 10 additional non-displaced femoral neck fractures, three complete and seven incomplete fractures, for an incidence of 15.7% (19/121). All identified femoral neck fractures were stabilized. DISCUSSION/CONCLUSION: The addition of rapid-sequence MRI of the pelvis in patients with high-energy femoral shaft fractures reliably increases the diagnosis of ipsilateral femoral neck fractures not identified with standard imaging. There were no cases of missed/delayed femoral neck fractures in patients with a negative MRI. This new imaging protocol effectively and safely improves the diagnosis of this injury pattern.

Outcomes of periprosthetic distal femur fractures following total knee arthroplasty: Intramedullary nailing versus plating.

BACKGROUND: Periprosthetic distal femur fractures (PPDFFs) present a challenge in terms of optimizing fixation in patients with poor bone quality and limited bone stock. The main treatment options include laterally based plating and intramedullary nailing. We hypothesized that treatment of PPDFFs with intramedullary nails would result in improved union rate, fewer complications, and an equivalent rate of malalignment compared to plating. MATERIALS AND METHODS: Cases of PPDFFs were identified through a query of our institutional trauma database between 2011-2018. Adult patients (>18 years) were included if they sustained a fracture of the distal femur around a total knee arthroplasty (TKA) that was not initially treated at another institution. The anatomic lateral distal femoral angle (aLDFA) and the anatomic posterior distal femoral angle (aPDFA) were measured on the follow-up radiographs. RESULTS: Ninety-seven PPDFFs in 97 patients, with a mean age of 76 years and 74% female were identified. Plating was used in 74 patients (76%) and 23 patients (24%) were treated with intramedullary nailing. Extension deformity in the sagittal plane was more common following intramedullary nailing compared to plating (10/23 nailing versus 10/74 plating) (p=0.002). There were 12 reoperations (12/75, 16%), and the method of fixation was not associated with rate of reoperation (p=0.9). CONCLUSION: Intramedullary nailing was associated with an increased risk of malalignment, most commonly an extension deformity, in this series. However, malalignment was not associated with worse outcomes.

The Competitive Orthopaedic Trauma Fellowship Applicant: A Program Director's Perspective.

INTRODUCTION: In 2018, orthopaedic trauma had the lowest match rate among orthopaedic subspecialties. The purpose of this study was to determine the importance of factors evaluated by orthopaedic trauma fellowship directors when ranking applicants after the interview. METHODS: An electronic survey was submitted to fellowship directors and consisted of 16 factors included in a fellowship application. Respondents were asked to rate the importance of these factors for applicants they interviewed on a 1 to 5 Likert scale, with 1 being not at all important and 5 being critical. RESULTS: Thirty-seven fellowship directors responded (63.8%). The highest-rated factor was the applicant interview (mean score 4.82), followed by the quality of letters of recommendation (4.69), personal connections made to the applicant (3.89), and potential to be leader (3.86). Fellowship directors at academic programs rated interest in an academic career (P = 0.003), research experience (P = 0.023), and exposure to well-known orthopaedic traumatologists (P = 0.003) higher than their counterparts at private institutions. Programs with more than one fellow rated potential to be a leader higher than programs with one fellow (P = 0.02). DISCUSSION: Trainees may use this study when compiling an application to optimize their chances of matching at the program of their choice.

Effect of Intrawound Vancomycin Powder in Operatively Treated High-risk Tibia Fractures: A Randomized Clinical Trial.

Importance: Despite the widespread use of systemic antibiotics to prevent infections in surgically treated patients with fracture, high rates of surgical site infection persist. Objective: To examine the effect of intrawound vancomycin powder in reducing deep surgical site infections. Design, Setting, and Participants: This open-label randomized clinical trial enrolled adult patients with an operatively treated tibial plateau or pilon fracture who met the criteria for a high risk of infection from January 1, 2015, through June 30, 2017, with 12 months of follow-up (final follow-up assessments completed in April 2018) at 36 US trauma centers. Interventions: A standard infection prevention protocol with (n = 481) or without (n = 499) 1000 mg of intrawound vancomycin powder. Main Outcomes and Measures: The primary outcome was a deep surgical site infection within 182 days of definitive fracture fixation. A post hoc comparison assessed the treatment effect on gram-positive and gram-negative-only infections. Other secondary outcomes included superficial surgical site infection, nonunion, and wound dehiscence. Results: The analysis included 980 patients (mean [SD] age, 45.7 [13.7] years; 617 [63.0%] male) with 91% of the expected person-time of follow-up for the primary outcome. Within 182 days, deep surgical site infection was observed in 29 of 481 patients in the treatment group and 46 of 499 patients in the control group. The time-to-event estimated probability of deep infection by 182 days was 6.4% in the treatment group and 9.8% in the control group (risk difference, -3.4%; 95% CI, -6.9% to 0.1%; P = .06). A post hoc analysis of the effect of treatment on gram-positive (risk difference, -3.7%; 95% CI, -6.7% to -0.8%; P = .02) and gram-negative-only (risk difference, 0.3%; 95% CI, -1.6% to 2.1%; P = .78) infections found that the effect of vancomycin powder was a result of its reduction in gram-positive infections. Conclusions and Relevance: Among patients with operatively treated tibial articular fractures at a high risk of infection, intrawound vancomycin powder at the time of definitive fracture fixation reduced the risk of a gram-positive deep surgical site infection, consistent with the activity of vancomycin. Trial Registration: ClinicalTrials.gov Identifier: NCT02227446.

Effect of Intraoperative Multidimensional Fluoroscopy Versus Conventional Fluoroscopy on Syndesmotic Reduction.

BACKGROUND: Despite multiple techniques to improve syndesmotic reduction accuracy, syndesmotic malreduction in unstable ankle fractures remains prevalent. We performed a prospective, observational study to assess the ability of intraoperative multidimensional fluoroscopy to lead a surgeon to change the syndesmotic reduction obtained by conventional fluoroscopic techniques with the goal of achieving an accurate reduction. METHODS: Thirty patients with unilateral malleolar ankle fractures and syndesmotic instability were enrolled. Following fixation of the malleollar fractures, the syndesmosis was provisionally reduced. Once the surgeon believed acceptable reduction was obtained by comparison with the contralateral, uninjured ankle mortise and lateral fluoroscopic images, provisional fixation was used to maintain reduction. Intraoperative, multidimensional fluoroscopy was used to generate cross-sectional images to assess the reduction. The surgeon then decided if a change in the reduction was needed, and fixation proceeded per surgeon preference. Postoperative bilateral computed tomography (CT) scans of the ankles were used to assess the reduction. RESULTS: The main outcome recorded was syndesmotic reduction change by the attending surgeon following 3-dimensional (3D) fluoroscopic imaging. The secondary outcome was syndesmotic reduction accuracy on postoperative CT scan. Fourteen of 30 patients had intraoperative reduction change following 3D fluoroscopic imaging. Three of 30 patients had residual malreduction compared with the contralateral ankle on bilateral postoperative CT scan. CONCLUSION: Intraoperative 3D fluoroscopy frequently led the surgeon to change the syndesmotic reduction obtained by conventional techniques and provided additional information not available with 2-dimensional fluoroscopy. A 10% syndesmotic malreduction rate was obtained with this technique. LEVEL OF EVIDENCE: Diagnostic level II, prospective comparative study.

Complication Rates after Lateral Plate Fixation of Periprosthetic Distal Femur Fractures: A Multicenter Study.

OBJECTIVE: Periprosthetic fractures of the distal femur can be challenging injuries to treat; nonunion rates of up to 22% have been reported. The purpose of this study was to determine the rate of complications and nonunion in a multicenter series, and to identify patient or surgical factors that were associated with nonunion. DESIGN: Retrospective comparative study SETTING: Three Level 1 trauma centers PATIENTS: Fifty-five patients with a periprosthetic distal femur fracture proximal to a total knee arthroplasty. Minimum follow up for inclusion was six months or until union or failure. INTERVENTION: Surgical fixation using a precontoured lateral locking plate MAIN OUTCOME MEASUREMENT: Fracture union was the primary outcome. Patient demographic and injury variables (age, comorbidities, fracture classification and characteristics) and surgical technique factors (mode of plate fixation, plate material, working length, screw density, and proximal screw type) were identified and compared between patients who developed a nonunion and those who did not. Regression analysis was performed to identify independent risk factors for nonunion. RESULTS: The overall rate of nonunion was 18% and the total complication rate was 24%. After additional surgery, 49 of 55 patients went on to heal (89%). There were no statistical differences in patient demographic or injury variables between the union and nonunion groups, and none of the variables studied were independent risk factors for nonunion in the regression analysis. CONCLUSIONS: In this series of 55 patients with periprosthetic distal femur fractures treated with precontoured lateral locking plates, 18% developed nonunion and the overall complication rate was 24%. No patient or surgical variables were identified as risk factors. Future research should seek to identify patients at high risk for complication and nonunion who could benefit from alternative fixation strategies or distal femoral replacement.

Increasing Fellow Recruitment: How Can Fellowship Program Websites Be Optimized?

BACKGROUND: The purpose of this study was to determine the importance of factors considered by orthopaedic trauma fellowship applicants when evaluating programs. We hypothesized that applicants will prioritize consistent factors when applying to programs. In addition, we assessed how the applicants use the Internet to research potential fellowships. Our goal is to provide fellowships with information to optimize both their fellowship and online contents. METHODS: At the 2018 and 2019 Orthopaedic Trauma Association meetings, a paper survey was given to each attendee of multiple fellowships' informational sessions. The survey consisted of 25 factors that applicants may consider when evaluating fellowships ranked on a 1-to-5 Likert scale. Additional questions were asked to determine how applicants use the Internet and social media when researching fellowships. RESULTS: We received 111 surveys (roughly a 56% response rate). Ninety-eight applicants (88%) indicated that they use fellowship websites to research fellowships. The utilization of fellowship websites was markedly greater than the use of other online resources. The highest rated factors surveyed were surgical experience (mean 4.95; SD 0.26), pelvic and acetabular experience (4.80; 0.52), lower extremity fracture experience (4.75; 0.58), and current faculty at the fellowship (4.55; 0.78). The lowest rated factors were the ability to moonlight (2.04; 1.08), salary (1.88; 1.12), and spine trauma experience (1.45; 0.87). Surgical experience and pelvic/acetabular experience were rated markedly higher than every other factor surveyed. DISCUSSION: To our knowledge, this is the first study to demonstrate that most orthopaedic trauma fellowship applicants use fellowship websites when researching programs. Programs may use this study to optimize their fellowship experience to reflect what the applicants value. In addition, programs may use this study as a guide when updating their websites. Fellowships with informative websites that meaningfully highlight their fellowship experience may have a competitive edge in attracting applicants to their programs.

Improving the Diagnosis of Ipsilateral Femoral Neck and Shaft Fractures: A New Imaging Protocol.

BACKGROUND: Despite increased awareness of ipsilateral femoral neck fractures in patients with high-energy femoral shaft fractures and advanced imaging with thin-cut high-resolution computed tomography (CT), failure of diagnosis remains problematic. The purpose of the present study was to determine if the preoperative diagnosis of ipsilateral femoral neck fractures in patients with high-energy femoral shaft fractures can be improved with magnetic resonance imaging (MRI) compared with radiographic and CT imaging. METHODS: In response to delayed diagnoses of femoral neck fractures despite thin-cut high-resolution CT, our institutional imaging protocol for acute, high-energy femoral shaft fractures was altered to include rapid limited-sequence MRI to evaluate for occult femoral neck fractures. All patients received standard radiographic imaging as well as thin-cut high-resolution pelvic CT imaging upon presentation. Rapid limited-sequence MRI of the pelvis was obtained to evaluate for an occult femoral neck fracture. RESULTS: Thirty-seven consecutive patients with 39 acute, high-energy femoral shaft fractures resulting from blunt trauma were included. The average age of the patients was 29.1 years (range, 14 to 82 years). Ten (25.6%) of the 39 femoral shaft fractures were open. Two femoral shaft fractures (5.1%) were associated with ipsilateral femoral neck fractures that were detected on radiographs, and no MRI was performed. None of the remaining 37 femoral shaft fractures were associated with a femoral neck fracture that was identified on CT imaging. Thirty-three (89.2%) of 37 patients underwent pelvic MRI to evaluate the ipsilateral femoral neck. Four (12.1%) of those 33 patients were diagnosed with a femoral neck fracture (2 complete, 2 incomplete) that was not identified on thin-cut high-resolution CT or radiographic imaging. CONCLUSIONS: Rapid limited-sequence MRI of the pelvis for patients with femoral shaft fractures identified femoral neck fractures that were not diagnosed on thin-cut high-resolution CT in 12% of our patients. Our results suggest that the frequency of femoral neck fractures may be underrepresented on CT imaging; rapid limited-sequence MRI was feasible without delaying definitive treatment even in polytraumatized patients.

Medialized Trochanteric Starting Point and Focused Lateral Endosteal Beak Reaming to Optimize Success of Intramedullary Nailing in Atypical Femur Fractures: A Technical Trick and Case Series.

Optimal intramedullary treatment of atypical femur fractures associated with bisphosphonate use requires avoidance of postoperative malreduction, particularly varus. This can be difficult to achieve, given the fracture location, errors with nail entry point, endosteal beaking, and underlying patient osteology, all of which can contribute to postoperative varus and predispose the patient to treatment failure. We present a surgical technique and clinical series of 10 patients emphasizing a medialized trochanteric nail entry point and preferential lateral endosteal reaming to secure a biologically and biomechanically favorable reduction and fixation.

Ninety-Five Degree Angled Blade Plate Fixation of High-Energy Unstable Proximal Femur Fractures Results in High Rates of Union and Minimal Complications.

OBJECTIVES: To describe the surgical technique and clinical outcomes of high-energy proximal femur fractures treated with a 95-degree angled blade plate. DESIGN: Retrospective case series. SETTING: Single academic Level I trauma center. PATIENT/PARTICIPANTS: Forty-five consecutive patients from March 2012 to April 2017 who sustained a high-energy, unstable proximal femur fracture including (OTA/AO 31-A1, 31-A2, 31-A3, 31-B3, 32-A1a, and 32-C3i). INTERVENTION: Open reduction internal fixation with a 95-degree angled blade plate used in conjunction with an articulated tensioning device. MAIN OUTCOME MEASUREMENTS: Nonunion, malunion, secondary operations, and postoperative infection. RESULTS: Twenty six patients were available for follow-up. The mean age was 43.8 (range 22-86) years, and 81% (21/26) were men. The most common fracture pattern was OTA/AO 31-A3.3. Two fractures were open. The articulated tensioner was used in 100% of cases. Average clinical follow-up was 19.2 (range 7-40) months. Twenty-four of 26 patients (92%) achieved osseous union after the index procedure. One patient underwent nonunion repair, and 2 patients had the blade plate removed as it was symptomatic laterally. No other secondary procedures were performed, and no instances of implant failure were seen. No patients had evidence of a superficial or deep infection. CONCLUSIONS: We found that high-energy proximal femur fractures treated with a 95-degree condylar blade plate and articulated tensioning device had a high rate of union with minimal postoperative complications. Although intramedullary nailing of these fractures remains a preferred treatment modality, the angled blade plate with articulated tensioning device is an excellent option to restore anatomical alignment and obtain bony union in certain highly comminuted fracture patterns.
