Preference Signaling in the Orthopaedic Surgery Match: Applicant and Residency Program Attitudes, Behaviors, and Outcomes.

Introduction: The orthopaedic surgery match has experienced a consistent increase in both the number of applicants and applications submitted per applicant. Preference signaling was implemented during the 2022 to 2023 application cycle in part to curtail the rising application burden on both applicants and residency programs. Our aim was to explore the impact of the preference signaling system on applicant and residency program leader attitudes, behaviors, and outcomes. Methods: We distributed surveys to American Orthopaedic Association/Council of Orthopaedic Residency Directors member program leaders (program directors, assistant program directors, and program coordinators) and applicants registered for the Electronic Standardized Letter of Recommendation after Universal Interview Offer Day 2022 (Fall Survey) and Match Day 2023 (Spring Survey). The surveys contained multiple-choice and numeric response questions on attitudes, behaviors, and outcomes that were analyzed and reported as percentages and medians, respectively. Open-text responses were reviewed for dominant themes. Results: One hundred program leaders and 378 applicants (47%) completed the Fall Survey, and 146 program leaders and 290 applicants (36%) completed the Spring Survey. A majority of applicants (71%) and program leadership (91%) support the continued use of signaling. Applicants reported a 16% reduction in the number of programs to which they applied. Program directors largely used signaling as a tool for screening applications (75%), with few programs using signaling in the ranking process (20%). Applicants reported that 81% of their interviews were from programs they signaled. Slightly more than half of programs (53%) reported filling their last slot at a higher rank order position than the average of the previous 5 years. Qualitative analysis suggests a need for more transparency in the use of signals, consideration of application and/or interview caps, and reconsideration of the other components of the application. Conclusion: Preference signaling in the orthopaedic surgery match was met with positive feedback and led to a reduction in the number of applications. Future research will examine the continued impact of preference signaling and assess alterations for optimizing the match process.

Perceived effectiveness of video interviews for orthopaedic surgery residency during COVID-19.

BACKGROUND: During the 2020-21 residency interview season, interviews were conducted through virtual platforms due to the COVID-19 pandemic. The purpose of this study is to assess the general perceptions of applicants, residents and attendings at a single, large, metropolitan orthopaedic residency with regards to the video interview process before and after the interview season. METHODS: Surveys were sent to all orthopaedic applicants, residents, and attendings before the interview season. Applicants who received interviews and responded to the first survey (46) and faculty who responded to the first survey (28) were sent a second survey after interviews to assess how their perceptions of video interviews changed. RESULTS: Initially, 50% of applicants (360/722) and 50% of faculty and residents (28/56) responded before interview season. After interviews, 55% of interviewees (25/46) and 64% of faculty and residents (18/28) responded. Before interviews, 91% of applicants stated they would prefer in-person interviews and 71% were worried that video interviews would prevent them from finding the best program fit. Before interviews, 100% of faculty and residents stated they would rather conduct in-person interviews and 86% felt that residencies would be less likely to find applicants who best fit the program. Comparing responses before and after interviews, 16% fewer applicants (p = 0.01) perceived that in-person interviews provide a better sense of a residency program and faculty and residents' perceived ability to build rapport with interviewees improved in 11% of respondents (p = 0.01). However, in-person interviews were still heavily favored by interviewees (84%) and faculty and residents (88%) after the interview season. CONCLUSIONS: In-person interviews for Orthopaedic Surgery Residency are perceived as superior and are preferred among the overwhelming majority of applicants, residents, and interviewers. Nevertheless, perceptions toward video interviews improved in certain domains after interview season, identifying potential areas of improvement and alternative interview options for future applicants.

Use of the Behavior Assessment Tool in 18 Pilot Residency Programs.

BACKGROUND: The purpose of this study was to determine the feasibility and evaluate the effectiveness of the American Board of Orthopaedic Surgery Behavior Tool (ABOSBT) for measuring professionalism. METHODS: Through collaboration between the American Board of Orthopaedic Surgery and American Orthopaedic Association's Council of Residency Directors, 18 residency programs piloted the use of the ABOSBT. Residents requested assessments from faculty at the end of their clinical rotations, and a 360° request was performed near the end of the academic year. Program Directors (PDs) rated individual resident professionalism (based on historical observation) at the outset of the study, for comparison to the ABOSBT results. RESULTS: Nine thousand eight hundred ninety-two evaluations were completed using the ABOSBT for 449 different residents by 1,012 evaluators. 97.6% of all evaluations were scored level 4 or 5 (high levels of professional behavior) across all of the 5 domains. In total, 2.4% of all evaluations scored level 3 or below reflecting poorer performance. Of 431 residents, the ABOSBT identified 26 of 32 residents who were low performers (2 or more < level 3 scores in a domain) and who also scored "below expectations" by the PD at the start of the pilot project (81% sensitivity and 57% specificity), including 13 of these residents scoring poorly in all 5 domains. Evaluators found the ABOSBT was easy to use (96%) and that it was an effective tool to assess resident professional behavior (81%). CONCLUSIONS: The ABOSBT was able to identify 2.4% low score evaluations (

Radiographic Predictors of Screw Cutout for Intertrochanteric Fractures Treated With Cephalomedullary Nails.

The objective of this study was to determine the predictive value of tip-apex distance (TAD) and Parker's ratio for screw cutout after treatment of intertrochanteric hip fractures with a long cephalomedullary nail. A total of 97 patients with AO/OTA 31-A1-A3 intertrochanteric fractures and a minimum follow-up of 8 weeks were included. Increased Parker's ratio on the anteroposterior radiograph (OR = 1.386, p < .003) and lateral radiograph (OR = 1.138, p < .028) was significantly associated with screw cutout. In a multivariable regression analysis, only the Parker's anteroposterior ratio was significantly associated with risk of screw cutout (OR = 1.393, p = .004), but TAD (OR = 0.977, p = .764) and Parker's lateral ratio (OR 1.032, p = .710) were not independent predictors of cutout. The study concluded that Parker's anteroposterior ratio is the most helpful measurement in predicting screw cutout. (Journal of Surgical Orthopaedic Advances 28(2):115-120, 2019).

Assessing the accuracy of intracameral phenylephrine preparation in cataract surgery.

PURPOSE: Unpreserved phenylephrine is often used as an off-licence intracameral surgical adjunct during cataract surgery to assist with pupil dilation and/or stabilise the iris in floppy iris syndrome. It can be delivered as a neat 0.2 ml bolus of either 2.5 or 10% strength, or in a range of ad-hoc dilutions. We wished to assess the accuracy of intracameral phenylephrine preparation in clinical practice. METHODS: Phenylephrine 0.2 ml was analysed both neat (2.5 and 10%) and in diluted form (ratio of 1:1 and 1:3). Samples were analysed using the validated spectrophotometric method. RESULTS: A total of 36 samples were analysed. The standard curve showed linearity for phenylephrine (R2 = 0.99). Wide variability was observed across all dilution groups. There was evidence of significant differences in the percentage deviations from intended results between dilutions (p < 0.001). Mean percentage deviation for 1:3 dilution was significantly greater than neat (p = 0.003) and 1:1 dilution (p = 0.001). There was no evidence of a significant difference between 1:1 and neat (p = 0.827). CONCLUSIONS: Current ad-hoc dilution methods used to prepare intracameral phenylephrine are inaccurate and highly variable. Small volume 1 ml syringes should not be used for mixing or dilution of drug. Commercial intracameral phenylephrine products would address dosage concerns and could improve surgical outcomes in cases of poor pupil dilation and/or floppy iris syndrome.

Proximal Tibiofibular Dislocation Repaired with Syndesmotic Suture Buttons: A Case Report.

INTRODUCTION: Dislocations of the proximal tibiofibular joint (PTFJ) are a relatively rare orthopedic injury. They are often repaired with open reduction internal fixation utilizing a transfixation screw. Limited data are available concerning alternative repair methods. CASE REPORT: This report details a 46-year-old male who presented with an open Type IIIA comminuted mid-shaft tibia and segmental fibula fractures after being struck by a car traveling 70mph. Computed tomography confirmed comminuted and displaced tibia and fibula fractures with PTFJ dislocation as well as air tracking through the anterior compartment of the leg communicating with the knee joint. He underwent open reduction internal fixation with intramedullary nailing of his tibial shaft fracture and PTFJ syndesmosis repair with two suture buttons. X-ray at post-operative follow-up 2 years later showed complete healing without evidence of failure or hardware loosening. CONCLUSION: This case illustrates a patient treated with suture buttons, which provides an alternative option in treating PTFJ dislocations with a reported decreased likelihood of hardware removal and faster return to work.

Short Versus Long Cephalomedullary Nails for Pertrochanteric Hip Fracture.

This study compared patients who underwent treatment with short or long cephalomedullary nails with integrated cephalocervical screws and linear compression. Patients with AO/OTA 31-A2 or A3 pertrochanteric fractures treated with either short (n=72) or long (n=97) InterTAN (Smith & Nephew, Memphis, Tennessee) cephalomedullary nails were reviewed. Information on perioperative measures (estimated blood loss, surgical time, and fluoroscopy time) and postoperative orthopedic complications (infection, implant failure, screw cutout, and periprosthetic femur fracture) was included. Estimated blood loss (short nail, 161 mL; long nail, 208 mL; P=.002) and surgical time (short nail, 64 minutes; long nail, 83 minutes; P=.001) were lower in the short nail group. There were no differences in fluoroscopy time (short nail, 90 seconds; long nail, 142 seconds; P=.071) or rates of infection (short nail, 1.4%; long nail, 3.1%; P=.637) or overall orthopedic complications (short nail, 11.1%; long nail, 9.3%; P=.798) between the 2 groups. The long nail group had a trend toward more screw cutouts (long nail, 5.2%; short nail, 0.0%; P=.134) but fewer periprosthetic femur fractures (short nail, 8.3%; long nail, 0.0%; P=.013). This study found a similar overall rate of orthopedic complications between short and long nails with integrated cephalocervical screws and linear compression. These results confirm the suspected advantages of short nails, including faster surgery and less blood loss; however, the rate of periprosthetic femur fracture remains high, despite changes to implant design.

Extraocular muscle atrophy and central nervous system involvement in chronic progressive external ophthalmoplegia.

BACKGROUND: Chronic progressive external ophthalmoplegia (CPEO) is a classical mitochondrial ocular disorder characterised by bilateral progressive ptosis and ophthalmoplegia. These ocular features can develop either in isolation or in association with other prominent neurological deficits (CPEO+). Molecularly, CPEO can be classified into two distinct genetic subgroups depending on whether patients harbour single, large-scale mitochondrial DNA (mtDNA) deletions or multiple mtDNA deletions secondary to a nuclear mutation disrupting mtDNA replication or repair. The aim of this magnetic resonance imaging (MRI) study was to investigate whether the ophthalmoplegia in CPEO is primarily myopathic in origin or whether there is evidence of contributory supranuclear pathway dysfunction. METHODS: Ten age-matched normal controls and twenty patients with CPEO were recruited nine patients with single, large-scale mtDNA deletions and eleven patients with multiple mtDNA deletions secondary to mutations in POLG, PEO1, OPA1, and RRM2B. All subjects underwent a standardised brain and orbital MRI protocol, together with proton magnetic resonance spectroscopy in two voxels located within the parietal white matter and the brainstem. RESULTS: There was evidence of significant extraocular muscle atrophy in patients with single or multiple mtDNA deletions compared with controls. There was no significant difference in metabolite concentrations between the patient and control groups in both the parietal white matter and brainstem voxels. Volumetric brain measurements revealed marked cortical and cerebellar atrophy among patients with CPEO+ phenotypes. CONCLUSION: The results of this study support a primary myopathic aetiology for the progressive limitation of eye movements that develops in CPEO.
