Aberrant lumbrical muscles causing carpal tunnel syndrome.
Two cases of carpal tunnel syndrome secondary to an abnormally proximal origin of the lumbrical muscles are presented. Division of the transverse carpal ligament and neurolysis of the median nerve was performed in both cases, resulting in complete relief of symptoms. The anomalous lumbrical muscle bellies were not resected.
