Complications of surgical release for carpal tunnel syndrome.
Review of a series of 186 operative cases of carpal tunnel release revealed 34 complications in 22 patients, for an incidence of 12%. Complications were grouped into seven categories: (1) inadequate section of the transverse carpal ligament (associated with both transverse and curved incisions), (2) symptoms related to damage to the palmar cutaneous branch of the median nerve, (3) reflex sympathetic dystrophy, (4) unsightly hypertrophic scar due to inappropriate incision, (5) damage to the superficial palmar arch following blind sectioning of the transverse carpal ligament, (6) bowstringing of the flexor tendons after excision of the transverse carpal ligament, and (7) adherence of the flexor tendons following excision of the mesotenon. Except for four of the complications, two each of bowstringing and reflex sympathetic dystrophy which occurred in our own practice, all of the complications were seen in patients referred for care. Most complications can be prevented by proper operative technique.
