Multiple nerve dysfunction after carpal tunnel release.
A case is reported of the delayed onset of multiple nerve dysfunction after simple carpal tunnel release. The patient received a local anesthetic with the use of an arm tourniquet. The multiple dysfunctions included radial sensory and motor dysfunction at 5 days, anterior interosseous nerve syndrome at 33 days, and ulna intrinsic motor loss between 33 and 77 days after operation. There was no recovery in the radial or anterior interosseous nerves after 5 months of conservative management. At operation the radial nerve was compressed by the intermuscular septum, and the anterior interosseous nerve was compressed by the superficialis arcade. Decompression was followed by complete recovery.
