Ulnar neuropathy at the wrist associated with aberrant flexor carpi ulnaris insertion.
A 36-year-old man who sustained an industrial hyperextension injury of the wrist complained of dysesthesia and pain in the ulnar nerve distribution, aggravated for months by wrist movement until exploration. The operation revealed an anomalous insertion of the flexor carpi ulnaris tendon disrupting a major portion of the ulnar nerve proximal to the pisiform. the symptoms were relieved completely after neurolysis and modification of the insertion of the tendon.
