Organ transplantation has become the treatment of choice for most patients suffering end stage diseases of the kidney, pancreas, liver, heart or lung. Vascularized Composite Allotransplantation (VCA) {a.k.a. composite tissue allotransplantation} is the term used to describe transplantation of multiple tissues (skin, muscle, bone, cartilage, nerve, tendon, vessel) as a functional unit (e.g. hand). Several recent advances in clinical organ transplant immunosuppression and experimental limb VCA have now made it feasible to consider clinical VCA for the functional restoration of patients with loss of one or both hands. This protocol facilitates the development of limb VCA at the Atlanta Veterans Affairs Medical Center (VAMC) and at Emory University for patients with below the elbow amputations. It will evaluate the patients' use of transplanted limb(s) in activities of daily living and compare the function of the transplanted hand to the function with their previous prosthesis. Patients with below the elbow amputations will be enrolled. Donor tissue will be recovered from deceased donors following the guidelines of and in cooperation with the regional Organ Procurement Organization. The transplantation procedure and postoperative care will be performed using the standard technique for limb replantation. Patients will receive standard immunosuppressive regimen. Rejections will be treated in keeping with experience from the solid organ transplant experience. Graft failure will be treated with allograft amputation.
This protocol will study patients with below the elbow amputations who are selected to undergo limb allotransplantation. We will study patients after they have been trained on the use of a prosthetic limb device prior to transplantation. We will treat them with immunosuppression known to prevent the rejection of other allografted tissues and designed to minimize their dependence on chronic maintenance immunosuppression. These patients will be studied to determine whether the transplanted limb functions better, worse or the same as a prosthetic hand, and to quantify those differences
