Essentials of Musculoskeletal Imaging (2026)-MSES331922-2026

Video Transcription

Video Summary

The transcript is a series of orthopedic imaging lectures focused on postoperative and trauma radiology.<br /><br />First, Dr. Janelle Thomas reviews shoulder arthroplasty, especially reverse total shoulder arthroplasty (RTSA). She explains RTSA components, common reporting mistakes, and key complications: scapular notching, coracoid and scapular spine/acromion fractures, instability, infection, and hardware malposition. She emphasizes careful review of all films, correct positioning, and the roles of CT and ultrasound. She also discusses preoperative CT planning and imaging findings in anatomic total shoulder and hemiarthroplasty, including subscapularis tears, supraspinatus tears, glenoid loosening, and joint narrowing.<br /><br />The lecture then shifts to MRI in acute lower extremity trauma. The speaker explains how MRI detects occult fractures, bone contusions, cartilage injuries, muscle strains and contusions, tendon tears and lacerations, and Lisfranc ligament injury. Examples include occult hip fractures, intertrochanteric extension of greater trochanter fractures, chondral fractures, growth plate injuries, hamstring strains, Achilles tears, and Lisfranc sprains/ruptures. MRI is highlighted as especially valuable when radiographs are negative but suspicion remains high.<br /><br />Next is a detailed talk on wrist and hand trauma imaging. It covers standard radiographic views, CT and MRI techniques, and common injuries such as distal radius fractures, scaphoid fractures, triquetral fractures, mallet finger, hook of hamate fractures, CMC fracture-dislocations, PIP dislocations, and trauma mimickers such as cosmetic calcium injections and epiphyseal scars.<br /><br />Finally, the speaker reviews orthopedic hardware basics: cortical vs cancellous screws, locking screws, LCDC plates, locking plates, combi plates, LISS plates, arthrodesis plates, tightrope syndesmotic fixation, clavicle constructs, and synthetic cartilage implants. The overarching theme is to stay curious, recognize modern implants, and carefully inspect postoperative imaging to avoid missed complications.
