Abstract Allografts of the forearm are still uncommon in the field of composite tissue allograft transplantation. In November 2007, a right-hand allograft and a left-hand/full-length forearm allograft were transplanted in a 30-year-old man who lost both hands and the vision in his left eye due to an explosion. The patient underwent alemtuzumab and steroid induction therapy. Tacrolimus, mycophenolate mofetil, and low doses of steroids were given to prevent rejection. The allografts were rejected 3 times, but these episodes were controlled successfully. The immunosuppressive regimen was switched from tacrolimus to sirolimus because of increased serum creatinine. The left allograft showed a flexion contracture due to muscle fibrosis that was conjectured to be associated with a perioperative ischemic injury and permitted only a Moberg-type key pinch. In contrast, an excellent grade of function was observed in the right allograft. The Disabilities of the Shoulder, Arm, and Hand score improved from 70.83 to 36.6 and intrinsic musculature returned to both allografts. The patient was able to work 2 years after transplantation. This is the first report of an ischemic injury related to the successful allotransplantation of a composite tissue.
