Free vascularized joint transfer from the nonreplantable digit as a free flap for primary reconstruction of complex hand injury.

We report our experience in treating a a patient with an electrical saw injury to the right hand that resulted in incomplete amputation of the ring and small fingers at the metacarpophalangeal (MCP) joint with segmental tissue loss. Ray amputation of the small finger was performed because of extensive tissue loss. The proximal interphalangeal joint of the nonreplantable small finger was transferred as a fillet flap for primary reconstruction of the severely damaged MCP joint of the ring finger after revascularization. Two years after surgery active range of motion of the reconstructed MCP joint was 35 degrees extension to 85 degrees flexion with no instability or pain.

Thirty-eight free fasciocutaneous flap transfers in acute burned-hand injuries.

The benefits of free flap transfers in the acute burn injury are early wound closure, early mobility, reduced hospitalization, and possibly limb salvage. This retrospective study will attempt to provide principles to the use of free fasciocutaneous flap for the reconstruction of acute burned-hand injuries. Between 1995 and 2004, 5521 patients were admitted to the burn unit at Linkou Chang Gung Memorial Hospital. Of these, 38 patients (0.7%) patients received free fasciocutaneous flap transfers. Each patient's chart was reviewed the following data: age, gender, burn injury type, percentage of the burned area to total body surface area, flap type, operations prior to free flap coverage, the size and location of recipient area, timing of free flap coverage, operative time, duration of hospital stay, complications, flap survival and returning to work. All 38 free flaps survived and healed well. Three flaps with partial necrosis due to wound infections required subsequent debridement and skin grafting. Arterial thrombosis occurred in one patient and was salvaged successfully. Minimal donor-site morbidity with no intraoperative mortality was observed. Free fasciocutaneous flap transfer is a safe, efficacious one-stage reconstruction for acute burned-hands with satisfactory aesthetic and functional outcomes. Flap survival is not affected neither by the etiologies of burn nor the timing of free flap coverage.

Operant studies of self-injurious hand biting in the Rett syndrome.

Two children with Rett syndrome were treated for their self-injurious hand biting. Results of an operant assessment showed that in both cases the behavior functioned as a self-stimulatory response. Differential reinforcement, combined with a response interruption technique, produced large reductions in the hand biting of both girls and increases in the motor performance (instruction following, toy play) of one girl. These results suggest that further operant investigations may be helpful in the understanding and management of the behavioral symptoms found in Rett syndrome.
