Radioscapholunate arthrodesis using low-profile dorsal pi plate.
Radioscapholunate arthrodesis is a desirable method to treat isolated radiolunate arthritis or ulnar translocation of the carpal bones. An intact midcarpal joint is a prerequisite for functional range of motion. Previously, high rates of nonunion were observed with these procedures, as rigid fixation was difficult to obtain with simple Kirschner wires and screws. ⋯ Rectangular retinacular flaps were used under and over the extensor tendons. We performed these arthrodeses in patients with lunate fossa arthritis after a distal radius fracture, and with ulnar translocation of the carpus. We have observed excellent clinical results with about 50% of wrist motion preserved and no cases of nonunion or delayed union.

Treatment of intra-articular distal radius fractures by the volar intrafocal Kapandji method: a case series.
At present, the most common treatment for intra-articular fractures with a volar fragment is open reduction and internal fixation with a volar locking plate. This manuscript describes and evaluates the safety and efficacy of a modified Kapandji technique with insertion of a volar Kirschner wire for osteosynthesis of intra-articular distal radius fractures with a volar fragment. Four patients treated with the "volar Kapandji technique" completed follow-up of at least 12 (12 to 54) months. ⋯ The mean loss of flexion was 13.7 (0 to 30) degrees, the mean loss of extension was 10 (0 to 30) degrees, the mean loss of supination was 0 degrees, and the mean loss of pronation was 10 (0 to 20) degrees. There was no loss in dorsal angulation, radial inclination, or radial length compared with the other hand. No early or late complications were recorded.

2,3 intercompartmental supraretinacular artery pedicled vascularized bone graft for scaphoid nonunions.
Scaphoid nonunion is a complex problem that may continue to exist despite conventional methods of bone grafting and internal fixation. Vascularized bone grafting has been proposed as a treatment option for scaphoid nonunions with or without avascular necrosis of the proximal pole. Zaidemberg and colleagues first introduced the dorsal distal radius graft that has gained considerable popularity in the past 2 decades. ⋯ The use of rigid internal fixation with screws also permitted early wrist range of motion and shorter periods of immobilization. In this article, we describe our surgical technique of harvesting the 2,3 intercompartmental supraretinacular artery pedicled vascularized bone graft. The anatomy, indications, contraindications, and complications of treatment are also detailed.

A groin flap is an axial-patterned cutaneous flap based on the superficial circumflex iliac arteriovenous system, which can provide soft-tissue coverage to defects on any aspect of the hand and the distal two thirds of the forearm. One of the presumed disadvantages of the pedicled groin flap is the discomfort experienced by the patient during the time required before flap division. ⋯ This technique avoids a lengthy flap and tubing, increases the patients comfort, and also makes the division and inset of the flap easier. As described, we have found this method simple and easy to duplicate.
