Acetabular Fracture

Chad Correa* and Sari Lahham, MD^

DOI: https://doi.org/10.21980/J8BK8K Issue 2:4[mrp_rating_result]
The non-contrast CT images show a minimally displaced comminuted fracture of the right acetabulum involving the acetabular roof, medial and anterior walls (red arrows), with associated obturator muscle hematoma (blue oval).

A Simulation Model for Extensor Tendon Repair

Elizabeth Aronstam, DO* and David T Overton, MD*

DOI: https://doi.org/10.21980/J8VS7X Issue 2:3[mrp_rating_result]
By the end of this educational session, the learner will be able to: 1) List the indications for extensor tendon repair in the emergency department, 2) recognize the indications for referral to orthopedic or hand surgery, 3) list the risks and benefits of emergency department extensor tendon repair, 4) perform an appropriate physical examination for a patient with a potential extensor tendon laceration, 5) list the maximum time limit of tourniquet application for this procedure, 6) list the materials needed for extensor tendon repair in the emergency department, 7) successfully repair a completely severed extensor tendon using four different techniques: horizontal mattress, figure of eight, modified Kessler and modified Bunnell, and 8) describe the appropriate splinting of a repaired extensor tendon.

Supracondylar Fracture

Jessica Andrusaitis, BS, MS* and Ben Feldman, MD*

DOI: https://doi.org/10.21980/J8492P Issue 2:3[mrp_rating_result]
History of present illness: A 15-year-old male presented to the emergency department with right elbow pain after falling off a skateboard.  The patient denied a decrease in strength or sensation but did endorse paresthesias to his hand.  On exam, the patient had an obvious deformity of his right elbow with tenderness to palpation and decreased range of motion at the

Galeazzi Fracture

Reid Honda, MD*

DOI: https://doi.org/10.21980/J8HS39 Issue 2:2[mrp_rating_result]
The X-ray showed an acute comminuted fracture of the distal diaphysis of the radius with disruption of the distal radioulnar joint, consistent with a Galeazzi fracture. The patient was then splinted and taken for operative reduction and internal fixation the following day.

Irreducible Traumatic Posterior Shoulder Dislocation

Blake Collier, DO* and Christopher Trigger, MD*

DOI: https://doi.org/10.21980/J8V884Issue 2:1[mrp_rating_result]
Radiographs demonstrated posterior displacement of the humeral head on the “Y” view (see white arrow) and widening of the glenohumeral joint space on anterior-posterior view (see red arrow). The findings were consistent with posterior dislocation and a Hill-Sachs type deformity. Sedation was performed and reduction was attempted using external rotation, traction counter-traction. An immediate “pop” was felt during the procedure. Post-procedure radiographs revealed a persistent posterior subluxation with interlocking at posterior glenoid. CT revealed posterior dislocation with acute depressed impaction deformity medial to the biceps groove with the humeral head perched on the posterior glenoid, interlocked at reverse Hill-Sachs deformity (see blue arrow).

Pseudogout and Calcium Pyrophosphate Disease

Andrew Williamson, MD*

DOI: https://doi.org/10.21980/J8QG66Issue 2:1[mrp_rating_result]
Radiographs of the knee showed multiple radio-dense lines paralleling the articular surface (see red arrows) consistent with calcium pyrophosphate crystal deposition within the joint often seen in calcium pyrophosphate disease (CPPD) also known as pseudogout.
