Visual Case Report of a Prosthetic Joint Infection and Chronic Dehiscence following a Total Knee Arthroplasty
DOI: https://doi.org/10.5070/M5.52251Radiographs demonstrated intact prosthetic components (blue) without acute fracture, tibial peri-stem lucency (green) concerning for loosening or infection, as well as joint effusion, and soft-tissue swelling.
A Case Report of Rare Bilateral Quadriceps Tendon Rupture Diagnosed by Point of Care Ultrasound (POCUS)
DOI: https://doi.org/10.5070/M5.52334Musculoskeletal assessment with POCUS revealed disruption of the left quadriceps tendon (blue arrows) indicated by a large hypoechoic gap (red arrow) with significant surrounding fluid throughout the quadriceps as well as a sizable left knee effusion (orange highlighting). The right lower extremity had a disrupted and retracted quadriceps tendon (yellow arrow) with associated fluid near the injury site and a small right knee joint effusion (orange highlighting). Therefore, he was diagnosed with bilateral quadriceps tendon ruptures.
Hematoma, Hemarthrosis, and Hemotympanum: A Case Report of Acquired Hemophilia A
DOI: https://doi.org/10.5070/M5.52344Non-contrast computed tomography (CT) scan of the left knee confirmed a small to moderate suprapatellar joint effusion with Hounsfield unit measurements suggestive of blood products (+47 Hounsfield units), consistent with acute hemarthrosis. The hemarthrosis appears as a gray, fluid-density collection slightly darker than the surrounding tissues that conforms to the suprapatellar space anterior to the femur, continuing distally between the femur and the patella.
Low-Cost, Reusable Fracture Reduction Task Trainer for Distal Radius Fractures
DOI: https://doi.org/10.5070/M5.52357Utilizing this task trainer, learners will be able to 1) identify key anatomic structures, 2) distinguish a Colles from a Smith fracture of the radius, 3) understand fracture reduction technique using traction, translation and angulation, 4) appreciate the amount of force required for manipulation of the distal fracture fragment, and 5) gain hands-on practice using a model with similar haptics to bone and soft tissue.
A Case Report on an Open Fracture Dislocation Injury of the Proximal Phalanx of the Thumb Resulting from Playing Cricket
DOI: https://doi.org/10.5070/M5.52278There was an open injury to the volar aspect of the right thumb at the interphalangeal joint, with exposed bone. There was no active bleeding from the wound. He had intact sensation to the entire thumb and hand. His radial pulse was normal with normal capillary refill in all digits of his right hand. He had intact wrist flexion, extension, abduction, and adduction; however, he was unable to flex or extend his thumb secondary to the injury. He had no other injuries to the rest of his right upper extremity. An x-ray was obtained which showed a right thumb proximal phalanx intra-articular fracture (proximal fracture fragment outlined in yellow, distal fracture fragment outlined in pink) at the interphalangeal joint with dorsal dislocation of the distal phalanx (outlined in red). There were no radiopaque foreign bodies.
The EMazing Race: A Novel Gamified Board and Clinical Practice Review for Emergency Medicine Residents
DOI: https://doi.org/10.21980/J8.52075By the end of this 2-hour session, learners will demonstrate their knowledge on the following board-related emergency medicine topics: Ob/GYN – links to 13.7 Complications of Delivery in Core Model of EM 2022, Renal/GU – links to 15.0 Renal and Urogenital Disorders in Core Model of EM 2022 and Splinting – links to 18.1.8.2 Extremity bony trauma, fracture in Core Model of EM 2022.
A Comprehensive and Modality Diverse Cervical Spine and Back Musculoskeletal Physical Exam Curriculum for Medical Students
DOI: https://doi.org/10.21980/J8RQ0NBy the end of this session, students will be able to: 1) demonstrate how to properly perform a cervical spine and back physical exam, 2) understand the reasoning behind cervical spine and back PE maneuvers, 3) identify the proper technique and equipment to use for the cervical spine and back PE, 4) understand normal and abnormal findings in the cervical spine and back PE, 5) accurately record and report exam findings for the cervical spine and back PE.
Orthopaedic Surgery Didactic Session Improves Confidence in Distal Radius Fracture Management by Emergency Medicine Residents
DOI: https://doi.org/10.21980/J8K365By the end of this didactic session, learners should be able to: 1) assess DRF displacement on pre-reduction radiography and formulate reduction strategies, 2) perform a closed reduction of a DRF, 3) apply a safe and appropriate plaster splint to patient with a DRF and assess the patient’s neurovascular status, 4) assess DRF post-reduction radiography for relative fracture alignment, and 5) understand appropriate follow-up and necessary return precautions.
