AANA25 Hip Access Pass-CONCURRENT SESSION 2F: Residents and Fellows Showcase

Video Transcription

Video Summary

The transcript captures a conference session of orthopedic research paper presentations and audience Q&A. Early talks focused on hip and lower-limb alignment. One team introduced a simple hip-specific MRI grading system for gluteus medius/minimus fatty atrophy, combining muscle thickness, fat percentage, and fat location, supported by an online calculator. In 100 MRIs, greater fat content and posterior/diffuse fat distribution correlated with common hip pathologies (tendon tears/tendonitis, cartilage loss, bursitis, and some labral tear associations). The group aims to establish reliability and future cutoffs to guide who benefits from abductor tendon repair.<br /><br />A second study evaluated full-length standing radiographs in patients with tibial torsional malalignment, comparing “feet forward” versus “knees/patella forward” positioning. Foot position significantly changed multiple alignment measures, including hip-knee-ankle angle and mechanical axis location, suggesting surgeons should consider functional stance and sometimes obtain additional imaging.<br /><br />A third hip arthroscopy study found larger acetabular labral tears (>60°) predicted worse long-term patient-reported outcomes and markedly higher, earlier conversion to total hip arthroplasty (~33% vs 8%), even after adjusting for age and arthritis grade.<br /><br />Later presentations addressed education, safety, and professional issues: fellow involvement modestly increased rotator cuff arthroscopy OR time (~15 minutes) without harming 2-year outcomes; an augmented reality arthroscopy curriculum improved intern simulator performance and confidence in under 5 hours/month; a survey of female orthopedic surgeons showed gaps in radiation-safety knowledge, inconsistent dosimeter/PPE use, and limited access to properly fitting protective gear. Additional work examined AI (ChatGPT/Google) accuracy for patient sports-medicine information (generally good, improving, and best when sources cited), publication fees in orthopedic journals (mean open-access cost ~$2,300; higher with impact factor), and gender diversity at meetings and sports-medicine fellowships, finding female moderators/visible DEI initiatives associated with greater female participation.
