Triangular fibrocartilage complex (TFCC) insertion into the fovea of the distal ulna plays a crucial role in stabilizing the distal radioulnar joint. Consequently, surgical reattachment against avulsion of the foveal TFCC insertion is required to stabilize the distal radioulnar joint. However, because of technical difficulties, no arthroscopic procedure for such a lesion has currently been established. ⋯ The avulsed portion of the TFCC is anchored to the fovea by means of a repair suture passed through the TFCC. To achieve normal tension of the TFCC, the suture is tied onto the periosteum around the proximal entrance of the osseous tunnel. Our arthroscopic technique is relatively simple and has great advantages for progressive healing at the attachment site between the TFCC and the fovea.

Fracture-dislocations in the small joints of the fingers are challenging injuries. The surgeon must choose an appropriate treatment based on fracture pattern, joint stability, and injury chronicity. ⋯ Similar injuries in the distal interphalangeal joint are more tolerant of fracture displacement and even joint subluxation. Dorsal dislocations of the metacarpophalangeal joint may be associated with shearing fractures of the metacarpal head but are most notable for the volar plate interposition that may block closed reduction.

There are a number of insults that can compromise the soft tissue envelope of the hand. Soft tissue reconstruction seeks to restore both the aesthetic appearance and the function of the hand. The purpose of this review is to describe recent advances in hand soft tissue reconstruction. ⋯ Flaps based on donor sites from the dorsal metacarpal artery system are finding continually expanding uses in hand reconstruction. Traditional notions of forearm-based donor tissue are being challenged, leading to better hand reconstructions with less donor morbidity. Finally, improvements in free tissue transfer enable the expansion of reconstructive possibilities available for hand coverage.

To investigate the long-term functional and clinical outcomes of a tendon transfer during basal joint interposition arthroplasty for osteoarthritis of the basal joint of the thumb, in which the origin of the abductor pollicis brevis (APB) and opponens pollicis is transferred to the flexor carpi radialis tendon, in order to increase the abduction moment arm of the thumb and provide dynamic stabilization of the base of the first metacarpal. ⋯ Therapeutic IV.

Trapezium excision with ligament reconstruction and tendon interposition has proved to be highly effective in the treatment of thumb carpometacarpal joint arthritis. Donor-site morbidity from autograft harvest can be avoided by using an allograft. We report the outcomes after suspension and interposition arthroplasty using an acellular dermal allograft (GraftJacket; Wright Medical Technology, Inc., Arlington, TN) for thumb carpometacarpal arthritis. ⋯ Therapeutic IV.
