A Case of Short Radiolunate Avulsion Injury: Magnetic Resonance Diagnosis and Surgical Reconstruction

Injury to the volar wrist capsule with short radiolunate ligament avulsion is uncommon and is often difficult to discern on advanced imaging, which can lead to a delay in diagnosis and the development of chronic wrist instability. We report a case of a short radiolunate ligament avulsion injury and a volar wrist capsular injury that went unrecognized for an extended period and led to chronic wrist pain and instability. We describe the magnetic resonance imaging findings of the injury and detail a successful surgical reconstruction technique.
