title: Acute carpal tunnel syndrome caused by anomalous muscle bellies: a case report.
abstract: We reported on an acute carpal tunnel syndrome that occurred two hours after the internal fixation of scaphoid. Operative exploration showed median nerve compression caused by flexor digitorum superficialis muscle bellies within the carpal tunnel. Symptoms were relieved immediately after the carpal tunnel release. This case was very rare because acute carpal tunnel syndrome was caused by swollen muscle bellies within the carpal tunnel after the initial operation for the trans-scaphoid perilunate dislocation. This clinical situation should be distinguished from compartment syndrome of forearm.
