Acute Brachialis Tear and Hematoma Caused by Closed Acute Elbow Posterior Dislocation / 대한스포츠의학회지

ABSTRACT

This report was designed to investigate a rare case that brachialis tear and hematoma caused by acute elbow posterior dislocation. We studied a 20-year-old male patient with right elbow joint pain after outstretched injury. Physical examination showed instability of hright elbow joint and simple radiography indicated a posterolateral dislocation of right elbow joint. Computed tomography taken after closed reduction using Parvin technique revealed a few small bone fragment located on posterior humerus capitulum. Magnetic resonance imaging showed complete tear of brachialis and anterior articular capsule with hematoma. The patient was managed with long arm splint and hinge brace for an elbow dislocation with brachialis rupture and hematoma. The elbow joint range of motion was recovered to be in a normal range, and pain was diminished. There are few reported cases of acute elbow posterior dislocation combined with brachialis rupture and hematoma. The patient showed good clinical outcome after conservative treatment.
