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.

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.

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.

Comparative Study
Comparison of loop-tendon versus end-weave methods for tendon transfer or grafting in rabbits.
The loop-tendon method for the stabilization of tendon transfers or grafts has been demonstrated previously to have greater initial tensile strength than that of the end-weave method. To our knowledge, a comparison of the mechanical strengths of these methods over the early postoperative period has not been made. The purpose of this study was to compare the mechanical strengths of loop-tendon and end-weave methods of repair during the early postoperative period in rabbit hind limb tendons. ⋯ The loop-tendon method provided greater strength than that of the end-weave method during the early postoperative period in rabbit tendons. The loop-tendon method may provide greater surgical repair strength during the early postoperative rehabilitation period than the end-weave method.
