Bilateral Proximal Radial Shaft Fracture Dislocations Resulting from 2 Separate Injuries with the Same Mechanism, Each Associated with Median Nerve Entrapment: A Case Report in a Gymnast Performing Back Hand Springs

Abstract

We report a rare case of entrapment of the median nerve following a closed fracture of the proximal one-fourth of the radius in an adolescent in failure of back hand spring. We proposed that the forearm pronation and the wrist extension in, “the Back Handspring position” made the median nerve close to the radius at one-fourth proximal radius, played an important role in this complication.
