title: Aberrant position of the ulnar nerve and artery overlying the carpal canal.
abstract: Many anomalies of the ulnar nerve and artery within the wrist have been described. We report the first known case of the ulnar nerve and artery overlying the midportion of the transverse carpal canal, leaving Guyon's canal empty. This anomaly has considerable consequences for surgeons considering endoscopic carpal release, because the ulnar nerve and artery are at significant risk of injury.
