RESUMO

BACKGROUND: There is significant variability both in how proximal humerus fractures (PHFs) are treated and the ensuing patient outcomes. The purpose of this study was to investigate which surgeon- and patient-specific factors contribute to decision-making in the treatment of adult PHFs. We hypothesized that orthopedic sub-specialty training creates inherent bias and plays an important role in management algorithms for PHFs. METHODS: We performed a prospective cohort investigation in 2 groups of surgeons-traumatologists (N = 25) and shoulder & elbow/sports surgeons (SES) (N = 26)-and asked them to provide treatment recommendations for 30 distinct clinical cases with standardized radiographic and clinical data. This is a population-based sample of surgeons who take trauma call and treat PHFs with different sub-specializations and practice settings including academic, hospital-employed, and private. Surgeons characterized based on subspecialty (trauma vs. SES), experience level (>10 vs. ≤10-years), and employment type (hospital- vs. non-hospital-employed). Chi-square analyses, logistic mixed-effects modeling, and relative importance analysis were used to evaluate the data. RESULTS: Of the patient-specific factors, we found that the management of PHFs is largely dependent on initial radiographs obtained. Traumatologists were more likely to offer open reduction internal fixation (ORIF) and less likely to offer arthroplasty: 69% ORIF (traumatologists) vs. 51% ORIF (SES, P < .001), 8% arthroplasty (traumatologists) vs. 17% (SES, P < .001). Traumatologists were less likely to change from operative (either ORIF or arthroplasty) to non-operative management compared to SES surgeons when presented with additional patient demographic data. Surgeon-specific factors contributed to more than one-half of the variability in decision-making of PHF management while patient-specific factors contributed to about one-third of the variability in decision-making. CONCLUSIONS: As physicians strive to advance the treatment for PHFs and optimize patient outcomes, our findings highlight the complex overlap between surgeon-, fracture-, and patient-specific factors in the final decision-making process.

RESUMO

BACKGROUND: The use of live and cadaveric animal models in surgical training is well established as a means of teaching and improving surgical skill in a controlled setting. We aim to review, evaluate, and summarize the models published in the literature that are applicable to Plastic Surgery training. MATERIALS AND METHODS: A PubMed search for keywords relating to animal models in Plastic Surgery and the associated procedures was conducted. Animal models that had cross over between specialties such as microsurgery with Neurosurgery and pinnaplasty with ear, nose, and throat surgery were included as they were deemed to be relevant to our training curriculum. A level of evidence and recommendation assessment was then given to each surgical model. RESULTS: Our review found animal models applicable to plastic surgery training in four major categories namely-microsurgery training, flap raising, facial surgery, and hand surgery. Twenty-four separate articles described various methods of practicing microsurgical techniques on different types of animals. Fourteen different articles each described various methods of conducting flap-based procedures which consisted of either local or perforator flap dissection. Eight articles described different models for practicing hand surgery techniques. Finally, eight articles described animal models that were used for head and neck procedures. CONCLUSIONS: A comprehensive summary of animal models related to plastic surgery training has been compiled. Cadaveric animal models provide a readily available introduction to many procedures and ought to be used instead of live models when feasible.

RESUMO

INTRODUCTION: Accurate prenatal diagnosis of abnormally invasive placenta (AIP) is fundamental because it significantly reduces maternal morbidities. MATERIAL AND METHODS: Medline, Embase, CINAHL and the Cochrane databases were searched. The primary aim of the present review was to elucidate the diagnostic accuracy of prenatal magnetic resonance imaging (MRI) in recognizing the severity of AIP, defined as the depth and topography of invasion. The secondary aim was to ascertain the strength of association between each MRI sign and the depth of placental invasion and to test their individual predictive accuracy in detecting such invasion. Inclusion criteria were studies on women who had prenatal MRI for ultrasound suspicion or the presence of clinical risk factors for AIP. Estimates of sensitivity, specificity, positive and negative likelihood ratios and diagnostic odds ratio were calculated using the hierarchical summary receiver characteristics curve model, and individual data random-effect logistic regression was used to calculate OR. RESULTS: Twenty studies (1080 pregnancies undergoing MRI mainly for the ultrasound suspicion of AIP) were included. MRI showed a sensitivity of 94.4% [95% confidence interval (CI) 15.8-99.9], 100% (95% CI 75.3-100) and 86.5% (95% CI 74.2-94.4) for detection of placenta accreta, increta and percreta, respectively; the corresponding values for specificity were 98.8% (95% CI 70.7-100), 97.3% (95% CI 93.3-99.3), 96.8% (95% CI 93.5-98.7). MRI identified 100% of cases with S1 and 100% of those with S2 invasion confirmed at surgery. Among the different MRI signs, intra-placental dark bands showed the best sensitivity for the detection of placenta accreta, increta and percreta; as well as abnormal intra-placental vascularity, uterine bulging was associated with a higher risk of increta and percreta, exophitic mass and bladder tenting with placenta percreta. CONCLUSION: Prenatal MRI has an excellent diagnostic accuracy in identifying the depth and the topography of placental invasion. However, these findings come mainly from studies in which MRI was performed as a secondary imaging tool in women already screened for AIP on ultrasound and might not reflect its actual diagnostic performance in detecting the severity of these disorders.

RESUMO

Tris(pentafluorophenyl)boron B(C6F5)3 is an effective catalyst for the hydrosilylative reduction of tertiary and N-phenyl secondary amides. It allows for the mild reduction of a variety of these amides in near quantitative yield, with minimal purification, at low temperatures, and with short reaction times. This reduction shows functional group tolerance for alkenes, nitro groups, and aryl halides, including aryl iodides.

RESUMO

Rupture of the rectus abdominis is a rare condition. We describe the case of a young male trainee paratrooper who presented with sudden onset severe lower abdominal pain that occurred during military training. Magnetic resonance imaging revealed full-thickness bilateral rupture of the rectus abdominis. Our management involved injecting botulinum toxin into the rectus muscles preoperatively, reconstructing the rectus muscles, and placing a supportive biosynthetic mesh. Postoperatively, our patient could walk pain-free at 3 weeks, jog pain-free at 10 weeks, and run up to 2 miles at 25 weeks. As there is no consensus on the management of this rare injury, we conducted a literature review on all cases reporting rupture of the rectus abdominis from the year 2000. After comparing the outcomes of conservatively versus surgically managed patients, we can conclude that generally, management of such defects is dependent on size, severity, and patient factors; however, surgical treatment yields comparable results to conservative treatment.

RESUMO

The modern management of open fractures was established after the foundational work of Gustilo and Anderson, but we continue to strive to determine the optimal treatment of open fractures to diminish the risk of infection. The ideal timing of antibiotics, presentation to the operating room, and timing of procedures such as flap coverage continue to be investigated with incremental changes recommended over the years. This article aims to provide the most recent review of the literature regarding the timing and management of both upper and lower extremity open fractures, pediatric open fractures, current topics of controversy, and the data supporting current treatment recommendations.

RESUMO

Introduction: The purpose of this study was to describe the outcomes after operative repair of ballistic femoral neck fractures. To better highlight the devastating nature of these injuries, we compared a cohort of ballistic femoral neck fractures to a cohort of young, closed, blunt-injury femoral neck fractures treated with open reduction and internal fixation (ORIF). Methods: Retrospective chart review identified all patients presenting with ballistic femoral neck fractures treated at three academic trauma centers between January 2016 and December 2021, as well as patients aged ≤50 with closed, blunt-injury femoral neck fractures who received ORIF. The primary outcome was failure of ORIF, which includes the diagnosis of non-union, avascular necrosis, conversion to total hip arthroplasty, and conversion to Girdlestone procedure. Additional outcomes included deep infection, postoperative osteoarthritis, and ambulatory status at last follow-up. Results: Fourteen ballistic femoral neck fractures and 29 closed blunt injury fractures were identified. Of the ballistic fractures, 7 (50%) patients had a minimum of 1-year follow-up or met the failure criteria. Of the closed fractures, 16 (55%) patients had a minimum of 1-year follow-up or met the failure criteria. Median follow-up was 21 months. 58% of patients with ballistic fractures were active tobacco users. Five of 7 (71%) ballistic fractures failed, all of which involved non-union, whereas 8 of 16 (50%) closed fractures failed (p=0.340). No outcomes were significantly different between cohorts. Conclusion: Our results demonstrate that ballistic femoral neck fractures are associated with high rates of non-union. Large-scale multicenter studies are necessary to better determine optimal treatment techniques for these fractures. Level of evidence: Level III. Retrospective cohort study.

RESUMO

BACKGROUND: The aim of the study is to investigate the differences between the extensile lateral (EL) and sinus tarsi (ST) approaches for the treatment of displaced intra-articular calcaneus fractures as treated by a single surgeon. METHODS: A retrospective cohort study performed at a Level 1 trauma center. One hundred twenty-nine consecutive intra-articular calcaneus fractures from 2011 to 2018 that were surgically treated by a single surgeon. Primary outcomes were time to surgery, operative time, postoperative restoration of the critical angle of Gissane, postoperative wound complications, and need for unplanned re-operation. RESULTS: Patient characteristics, including demographics, mechanism of injury, and fracture patterns were similar between the EL and ST approach groups. There was a significant decrease in unplanned secondary procedures (P = .008), shorter time to definitive fixation (P = .00001), and shorter average operative time in the ST group (P = .00001). Postoperative measurement of the critical angle of Gissane between the two groups was significantly different, but minute with an average difference of approximately 3 degrees (P = .025). Measurements in both groups were within the expected range of normal. CONCLUSIONS: For displaced intra-articular calcaneus fractures, a limited open ST approach is associated with a significant reduction in the time to definitive fixation and decreased operative time. The EL approach was associated with a small, but significant improvement in the restoration of the critical angle of Gissane compared with the ST approach. Therefore, an ST approach may allow for earlier surgical intervention and result in equivalent quality of reduction compared with an EL approach. LEVEL OF EVIDENCE: Level III.

RESUMO

OBJECTIVE: To correlate patient-specific and surgeon-specific factors with outcomes after operative management of distal intra-articular tibia fractures. DESIGN: Retrospective cohort study. SETTING: 3 Level 1 tertiary academic trauma centers. PATIENTS/PARTICIPANTS: The study included a consecutive series of 175 patients with OTA/AO 43-C pilon fractures. MAIN OUTCOME MEASUREMENTS: Primary outcomes included superficial and deep infection. Secondary outcomes included nonunion, loss of articular reduction, and implant removal. RESULTS: The following patient-specific factors correlated with poor surgical outcomes: increased age with superficial infection rate ( P < 0.05), smoking with rate of nonunion ( P < 0.05), and Charlson Comorbidity Index with loss of articular reduction ( P < 0.05). Each additional 10 minutes of operative time over 120 minutes was associated with increased odds of requiring I&D and any treatment for infection. The same linear effect was seen with the addition of each fibular plate. The number of approaches, type of approach, use of bone graft, and staging were not associated with infection outcomes. Each additional 10 minutes of operative time over 120 minutes was associated with an increased rate of implant removal, as did fibular plating. CONCLUSIONS: While many of the patient-specific factors that negatively affect surgical outcomes for pilon fractures may not be modifiable, surgeon-specific factors need to be carefully examined because these may be addressed. Pilon fracture fixation has evolved to increasingly use fragment-specific approaches applied with a staged approach. Although the number and type of approaches did not affect outcomes, longer operative time was associated with increased odds of infection, while additional fibular plate fixation was associated with higher odds of both infection and implant removal. Potential benefits of additional fixation should be weighed against operative time and associated risk of complications. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

INTRODUCTION: It is our hypothesis that physician-specific variables affect the management of distal radius (DR) fractures in addition to patient-specific factors. METHODS: A prospective cohort study was conducted evaluating treatment differences between Certificate of Additional Qualification hand surgeons (CAQh) and board-certified orthopaedic surgeons who treat patients at level 1 or level 2 trauma centers (non-CAQh). After institutional review board approval, 30 DR fractures were selected and classified (15 AO/OTA type A and B and 15 AO/OTA type C) to create a standardized patient data set. The patient-specific demographics and surgeon's information regarding the volume of DR fractures treated per year, practice setting, and years posttraining were obtained. Statistical analysis was done using chi-square analysis with a postanalysis regression model. RESULTS: A notable difference was observed between CAQh and non-CAQh surgeons. Surgeons in practice longer than 10 years or who treat >100 DR fractures/year were more likely to choose surgical intervention and obtain a preoperative CT scan. The two most influential factors in decision making were the patients' age and medical comorbidities, with physician-specific factors being the third most influential in medical decision making. DISCUSSION: Physician-specific variables have a notable effect on decision making and are critical for the development of consistent treatment algorithms for DR fractures.

RESUMO

Cannabinoid compounds are being increasingly used as an analgesic adjuvant in the orthopedic population, but little data exist to either support or oppose this practice pattern. A review of all contemporary (2000-2020) studies on the use of cannabinoids in orthopedics is presented. Physicians and patients are optimistic that cannabinoids can decrease pain scores and perhaps opioid use; however, their application in orthopedics is not well characterized. In addition to the social stigma regarding the use of cannabis, there is limited high-quality evidence of the efficacy of cannabinoids in treating orthopedic-related pain. As cannabis becomes more accessible, well-designed trials are needed to better understand cannabinoids and guide orthopedic practice. [Orthopedics. 2022;45(6):e295-e302.].

RESUMO

INTRODUCTION: CT and three-dimensional (3D) CT reconstructions have been shown to improve the understanding of acetabular fractures. With the increased availability of 3D pelvic CT reconstructions, our goal for this study was to develop an algorithm to aid residents in the classification of acetabular fractures. We hypothesized that the use of a stepwise algorithm will markedly enhance the trainees' ability to correctly identify acetabular fracture patterns. METHODS: This was a multicenter study that included 33 residents. Residents reviewed 15 sets of 3D reconstructions of the 10 acetabular fracture patterns. Residents completed the first round, and the results were collected electronically. Three weeks later, they were asked to classify the fractures a second time with the use of the algorithm. The number of correct responses from the two sessions was analyzed to determine if the algorithm improved residents' ability to correctly classify fracture patterns. RESULTS: Thirty-three residents classified 15 fractures which yielded 495 unique responses. Residents correctly classified 52.5% (260/495) of fractures without the algorithm, which significantly increased to 77.5% (384/495) (P = 0.001) with the algorithm. When stratified by year in residency, all residents were able to correctly classify markedly more fractures with the algorithm. DISCUSSION: Overall, we believe this method is a reproducible diagnostic tool that will assist residents in classifying acetabular fractures. We were able to demonstrate that with the use of this algorithm, residents' ability to correctly classify acetabular fractures is markedly enhanced, regardless of year in training. This algorithm will be a useful adjunct to assist and advance trainees' education and understanding of a complex topic.

RESUMO

BACKGROUND: It is unclear which pharmacological agents, and at what dosage and timing, are most effective for venous thromboembolism (VTE) prophylaxis in patients with pelvic/acetabular fractures. METHODS: We searched the Cochrane Database of Systematic Reviews, Embase, Web of Science, EBSCO, and PubMed on October 3, 2020, for English-language studies of VTE prophylaxis in patients with pelvic/acetabular fractures. We applied no date limits. We included studies that compared efficacy of pharmacological agents for VTE prophylaxis, timing of administration of such agents, and/or dosage of such agents. We recorded interventions, sample sizes, and VTE incidence, including deep vein thrombosis (DVT) and pulmonary embolism. RESULTS: Two studies (3604 patients) compared pharmacological agents, reporting that patients who received direct oral anticoagulants (DOACs) were less likely to develop DVT than those who received low molecular weight heparin (LMWH) (p < 0.01). Compared with unfractionated heparin (UH), LMWH was associated with lower odds of VTE (odds ratio [OR] = 0.37, 95% confidence interval [CI]: 0.22-0.63) and death (OR = 0.27, 95% CI: 0.10-0.72). Three studies (3107 patients) compared timing of VTE prophylaxis, reporting that late prophylaxis was associated with higher odds of VTE (OR = 1.9, 95% CI: 1.2-3.2) and death (OR = 4.0, 95% CI: 1.5-11) and higher rates of symptomatic DVT (9.2% vs. 2.5%, p = 0.03; and 22% vs. 3.1%, p = 0.01). One study (31 patients) investigated dosage of VTE prophylaxis, reporting that a higher proportion of patients with acetabular fractures were underdosed (23% of patients below range of anti-Factor Xa [aFXa] had acetabular fractures vs. 4.8% of patients within adequate range of aFXa, p<0.01). CONCLUSIONS: Early VTE chemoprophylaxis (within 24 or 48 h after injury) was better than late administration in terms of VTE and death. Many patients with acetabular fractures are underdosed with LMWH, with inadequate aFXa levels. Compared with UH, LMWH was associated with lower odds of VTE and death. DOACs were associated with lower risk of DVT compared with LMWH. LEVEL OF EVIDENCE: III, systematic review of retrospective cohort studies.

RESUMO

OBJECTIVE: The purpose of this study was to evaluate transabdominal pelvic ultrasound and MRI for the prenatal diagnosis of placenta accreta. MATERIALS AND METHODS: A historical cohort pilot study was performed at our institution to identify women at risk of placenta accreta who had undergone both prenatal ultrasound and MRI. Findings at ultrasound and MRI were compared with the final diagnosis, which was established with clinical findings at delivery and pathologic examination of specimens. Volume measurements were made of low-signal-intensity intraplacental bands on T2-weighted MR images. Risk factors for placental insufficiency were recorded. RESULTS: Thirteen patients at risk of placenta accreta underwent both sonography and MRI. Nine of these patients had abnormal placentation. With ultrasound, abnormal placentation was correctly identified in six of nine patients (67%) and the absence of accreta in two of four patients (50%). With MRI, abnormal placentation was correctly identified in seven of nine patients (78%) and the absence of accreta in three of four patients (75%). The volumes of low-signal-intensity bands were significantly different in the patients with abnormal placentation and those without placenta accreta (p = 0.047), and band volumes were significantly different among patients with accreta, increta, and percreta (p < 0.0005). CONCLUSION: The accuracy of MRI may improve if volumes of low-signal-intensity bands are calculated, MRI is performed before 30 weeks' gestation, and risk factors for placental insufficiency are recognized.

RESUMO

INTRODUCTION: Cannabinoids are an increasingly popular therapy among orthopaedic patients for musculoskeletal conditions. A paucity of evidence to support their use in orthopaedics exists, likely because of the incongruence of federal and state legalization and the stigma surrounding cannabis. The purpose of this study is to elucidate sentiments and knowledge base of the orthopaedic trauma community with regard to cannabinoid-containing compounds. METHODS: A 21-question online survey was distributed to the members of the Orthopaedic Trauma Association with a response window of 3 months. RESULTS: We evaluated 251 responses. Most (88%) of the respondents did not believe that they were knowledgeable about the mechanism of action of cannabis/cannabidiol (CBD) but did feel that cannabis or CBD products play a role in managing postoperative pain (73%). Most respondents did not believe that they would be stigmatized if they suggested CBD (83%) or cannabis (67%) to patients. Despite this, fewer respondents have suggested CBD (38%) or cannabis (29%) to their patients. CONCLUSIONS: Sentiment toward cannabinoids among orthopaedic traumatologists is remarkably favorable; however, in-depth understanding is admittedly poor and routine use is uncommon. More clinical research for cannabinoids is needed to help orthopaedic traumatologists provide guidance for patients seeking advice for this recently popular therapeutic.

RESUMO

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.

RESUMO

INTRODUCTION: The goal of this study was to identify the current practices and rationale of orthopaedic surgeons regarding venous thromboembolism (VTE) prophylaxis for pelvic and acetabular (P&A) fractures. METHODS: A 25-item web-based questionnaire was made available to all Orthopaedic Trauma Association (OTA) members on the OTA website. Analysis of data was performed after the three-month study period. RESULTS: One hundred three active OTA members completed the survey. Most respondents practiced at an academic level I trauma centers. The most important factor in selecting a VTE regimen was its effectiveness, whereas cost was the least important. Low-molecular-weight heparin (LMWH) remains the preferred agent for VTE prophylaxis after P&A trauma. Factors such as surgical intervention and weight-bearing had a variable effect on surgeons' opinions regarding the type and duration of VTE prophylaxis. CONCLUSION: Most surgeons treating P&A fractures use LMWH for VTE prophylaxis, but the decision on which agent to use and duration of treatment is multifactorial. Published VTE prophylaxis literature and guidelines provide some guidance, but there is no consensus. Overall, LMWH appears to be the VTE prophylaxis agent of choice for most orthopaedic trauma surgeons, irrespective of nonsurgical or surgical management of these fractures.

RESUMO

INTRODUCTION: Obesity is an epidemic facing the United States affecting nearly 40% of the population (93.3 million adults). The objective of this study was to compare early perioperative complications in patients with a normal BMI to patients who are pre-obese, obese, and morbidly obese. MATERIALS AND METHODS: The study was conducted at a Level-I trauma center. Patients were separated into 4 groups based on their BMI. Group 1 had a BMI < 25 (normal), Group 2 had a BMI between 25-29.9 (pre-obesity), Group 3 had a BMI between 30-39.9 (obese), and Group 4 had a BMI ≥40 (morbidly obese). Outcome variables included total operative time (OT), estimated blood loss (EBL), length of stay (LOS), and early medical and surgical complications. A comparison between groups was performed for each outcome variable and surgical complication. RESULTS: We identified 333 patients and the number of patients in Groups 1-4 were 86, 96, 121, and 30, respectively. The average BMI for Groups 1-4 was 22.3, 27.3, 35.9, and 44.9, respectively (p < 0.001). OT, EBL, and LOS did not differ between groups or between the surgical approach utilized. There were no significant relationships when comparing complication rates between groups. Patients in Group 4 experienced significantly more PE compared to patients in Group 2 (p=0.01). Additionally, patients in Group 4 experienced a significantly more PE than patients in Groups 1 and 2 combined (p<.01). The relative risk of having a PE if BMI is ≥40, compared to a BMI <30 is 18.40 (95% CI = 1.98 - 171.13). The PEs were not fatal in all cases. CONCLUSIONS: In the treatment of the obese and morbidly obese with acetabular fractures, we find that these cohorts are not at a greater risk of wound complications or infection. The higher rate of pulmonary embolism seen in the morbidly obese should be considered when evaluating these patients for appropriate thromboembolic prophylaxis.

RESUMO

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.

RESUMO

OBJECTIVE: To determine whether intramedullary nail (IMN) size and its relation to the canal diameter [nail-canal (NC) diameter] impacts the union rate or time to union in the treatment of femoral shaft fractures. DESIGN: Retrospective review. SETTING: Two Level 1 and 1 Level 2 trauma centers. PATIENTS: Two hundred eighty-seven patients met the criteria and were included in the study. INTERVENTION: Patients were treated with either an antegrade or retrograde IMN. Comparisons were first performed comparing 10- versus 11- versus 13-mm nails. Patients were then divided into 3 groups based on the difference between the size of the femoral canal at the isthmus and the IMN (NC diameter). Group 1: <1.0 mm, group 2: >1.0 and <2.0 mm, and group 3: >2.0 mm. MAIN OUTCOME MEASUREMENTS: Nonunion rates, mean time to union. RESULTS: Two hundred eighty-seven patients with a minimum of 12-month follow-up, who were treated with size with IMN for femoral shaft fractures, were assessed for fracture characteristics, time to union, and union rate. When comparing IMN size, no statistical difference was found when comparing time to union or overall union rate. When comparing NC diameter, no significant difference was found in union rate and time to union when comparing between the groups. CONCLUSION: Similar rate of union and time to union were exhibited regardless of nail size or NC diameter. This can correlate to the standard utilization of a reamed, titanium 10-mm IMN with 5.0-mm interlocking screws in the treatment of femoral shaft fractures, offering potentially less reaming, shorter operative times, and removing unnecessary stock from inventory. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
