Abstract
Background Recipients of Vascularized Composite Allotransplants require effective immunosuppressive therapy to prevent graft rejection. This systematic review summarizes the current body of literature on immunosuppressive regimens used in face and hand transplants while summarizing their outcome in terms of rejection, renal failure, and infections. Methods A systematic search of electronic databases was conducted to identify relevant studies from 1998 until July 1st, 2023. We included all studies that discussed immunosuppressive strategies in face and hand transplant recipients according to PRISMA. Results The standard triple maintenance therapy was mostly adjusted due to nephrotoxicity or high incidence of rejection. The most common alternative treatments utilized were sirolimus (25/91; 27.5%) or everolimus (9/91; 9.9%) following hand- and photophoresis (7/45; 15.6%), sirolimus (5/45; 11.1%) or belatacept (1/45; 2.2%) following face transplantation. Episodes of rejection were reported in 60 (65.9%) of hand- and 33 (73%) of face transplant patients respectively. Graft loss of 12 (13.2%) hand and 4 (8.9%) face transplants was reported. Clinical CMV infection was observed in 6 (6.6%) hand and 7 (15.5%) face transplant recipients. Conclusions Based on the herein presented data, facial grafts exhibited a heightened incidence of rejection episodes and CMV infections. Facial mucosa adds complexity to the immunological graft composition highlighting the need of individualized immunosuppressive regimens and further research.

Abstract
ABSTRACT Hand transplantation for upper extremity amputation provides a unique treatment that restores form and function, which may not be achieved by traditional reconstruction and prosthetics. However, despite enhancing quality of life, hand transplantation remains controversial, because of immunological complications, transplant rejection, and medication effects. This systematic literature review sought to collect information on current experiences and outcomes of hand transplants to determine the efficacy and utility of hand transplants. The databases PubMed, Scopus, and Embase were analyzed with combinations of "hand" or "upper extremity" or "arm" and "transplant" or "allograft," with information collected on recipient characteristics, details of transplant, immunological outcomes, functional outcomes, and complications. Functional outcomes, as measured by Disabilities of Arm, Shoulder and Hand score, were compared between patient groups using Wilcoxon signed-rank test or 1-way analysis of variance test and post hoc Tukey test. Within the 108 articles that fulfilled inclusion and exclusion criteria, there were 96 patients with 148 hand transplants. There were 57 patients who experienced acute rejection and 5 patients with chronic rejection. Disabilities of the Arm, Shoulder and Hand scores significantly decreased after hand transplantation and were significantly lower for distal transplants compared with proximal transplants. There were 3 patients with concurrent face transplantation and 2 patients with simultaneous leg transplants. Sixteen patients experienced amputation of the hand transplant, and there were 5 deaths. This study found that hand transplantation provides significant restoration of function and form, especially for proximal transplants. Reduction in complications, such as rejection and amputation, can be achieved by decreasing medication cost and patient education.

Abstract
Between 2000 and 2014, five patients received bilateral hand (n = 3), bilateral forearm (n = 1), and unilateral hand (n = 1) transplants at the Innsbruck Medical University Hospital. We provide a comprehensive report of the long-term results at 20 years. During the 6-20 years follow-up, 43 rejection episodes were recorded in total. Of these, 27.9% were antibody-related with serum donor-specific alloantibodies (DSA) and skin-infiltrating B-cells. The cell phenotype in rejecting skin biopsies changed and C4d-staining increased with time post-transplantation. In the long-term, a change in hand appearance was observed. The functional outcome was highly depending on the level of amputation. The number and severity of rejections did not correlate with hand function, but negatively impacted on the patients´ well-being and quality of life. Patient satisfaction significantly correlated with upper limb function. One hand allograft eventually developed severe allograft vasculopathy and was amputated at 7 years. The patient later died due to progressive gastric cancer. The other four patients are currently rejection-free with moderate levels of immunosuppression. Hand transplantation remains a therapeutic option for carefully selected patients. A stable immunologic situation with optimized and individually adopted immunosuppression favors good compliance and patient satisfaction and may prevent development of DSA.

Abstract
INTRODUCTION Vascularised composite allotransplantation (VCA) permits like-for-like reconstruction following extensive soft tissue injuries. The initial management of extensive soft tissue injury can lead to the development of anti-HLA antibodies through injury-related factors, transfusion and cadaveric grafting. The role of antibody-mediated rejection, donor-specific antibody formation and graft rejection in the context of VCA remains unclear. This systematic review aimed to determine whether pre-transplant management strategies influence immunological outcome following VCA. METHODS A systematic review of MEDLINE, EMBASE and CINAHL using a PRISMA-compliant methodology up to February 2019 was conducted. Pre-transplant, procedural and long-term outcome data were collected and recorded for all VCA recipients on an individual patient basis. RESULTS The search revealed 3,847 records of which 114 met inclusion criteria and reported clinical data related to 100 patients who underwent 129 VCA transplants. Trauma (50%) and burns (15%) were the most frequent indications for VCA. Of all 114 studies, only one reported acute resuscitative management. Fifteen patients were sensitised prior to reconstructive transplantation with an 80%%incidence of acute rejection in the first post-operative year. Seven patients demonstrated graft vasculopathy, only one of whom had demonstrated panel reactive antibodies. CONCLUSIONS Currently employed acute management strategies may predispose to the development of anti-HLA antibodies, adding to the already complex immunological challenge of VCA. To determine whether association between pre-transplant management and outcomes exists, further refinement of international registries is required.

Abstract
Amputations have a devastating impact on patients' health with consequent psychological distress, economic loss, difficult reintegration into society, and often low embodiment of standard prosthetic replacement.The main characteristic of bionic limbs is that they establish an interface between the biological residuum and an electronic device, providing not only motor control of prosthesis but also sensitive feedback.Bionic limbs can be classified into three main groups, according to the type of the tissue interfaced: nerve-transferred muscle interfacing (targeted muscular reinnervation), direct muscle interfacing and direct nerve interfacing.Targeted muscular reinnervation (TMR) involves the transfer of the remaining nerves of the amputated stump to the available muscles.With direct muscle interfacing, direct intramuscular implants record muscular contractions which are then wirelessly captured through a coil integrated in the socket to actuate prosthesis movement.The third group is the direct interfacing of the residual nerves using implantable electrodes that enable reception of electric signals from the prosthetic sensors. This can improve sensation in the phantom limb.The surgical procedure for electrode implantation consists of targeting the proximal nerve area, competently introducing, placing, and fixing the electrodes and cables, while retaining movement of the arm/leg and nerve, and avoiding excessive neural damage.Advantages of bionic limbs are: the improvement of sensation, improved reintegration/embodiment of the artificial limb, and better controllability.

Abstract
BACKGROUND Although return of function has been reported in patients undergoing proximal forearm transplantations (PFTs), reports of long-term function are limited. In this study, we evaluated the clinical progress and function 7 years postoperatively in a patient who underwent bilateral PFT. CASE PRESENTATION A 58-year-old man underwent bilateral PFT in May 2012. Transplantation involved all of the flexor and extensor muscles of the forearm. Neurorrhaphies of the median, ulnar, and radial nerves were epineural and 7 cm proximal to the elbow. Immunosuppressive maintenance medications during the first 3 years postoperatively were tacrolimus, mycophenolate, and steroids, and later, tacrolimus, sirolimus, and steroids. Forearm function was evaluated annually using the Disabilities of the Arm, Shoulder, and Hand; Carroll; Hand Transplantation Score System; Short Form-36; and Kapandji scales. We also evaluated his grip and pinch force. RESULTS Postoperatively, the patient developed hypertriglyceridemia and systemic hypertension. He experienced 6 acute rejections, and none were resistant to steroids. Motor function findings in his right/left hand were: grip strength: 10/13 kg; key pinch: 3/3 kg; Kapandji score: 6/9 of 10; Carroll score: 66/80; Hand Transplantation Score System score: 90/94. His preoperative Disabilities of the Arm, Shoulder, and Hand score was 50 versus 18, postoperatively; his Short Form-36 score was 90. This function improved in relation with the function reported in the second year. CONCLUSIONS Seven years following PFT, the patient gained limb strength with a functional elbow and wrist, although with diminished digital dexterity and sensation. Based on data presented by other programs and our own experience, PFT is indicated for select patients.

Abstract
Hand loss is a catastrophic event that generates significant demands for orthopedics and prosthetics. In the course of history, prostheses evolved from passive esthetic replacements to sophisticated robotic hands. Yet, their actuation and particularly, their capacity to provide patients with sensations, remain an unsolved problem. Sensations associated with the hand, such as touch, pain, pressure and temperature detection are very important, since they enable humans to gather information from the environment. Recently, through a synergistic multidisciplinary effort, medical doctors and engineers have attempted to address these issues by developing bionic limbs. The aim of the bionic hands is to replace the amputated hands while restoring sensation and reintroducing hand-motor control. Recently, several different approaches have been made to interface this sophisticated prosthesis with residual neuro-muscular structures. Different types of implants, such as intramuscular, epineural and intraneural, each have their own complementary advantages and disadvantages, which are discussed in this paper. After initial trials with percutaneous leads, present research is aimed at making long-term implantable electrodes that give rich, natural feedback and allow for effortless control. Finally, a pivotal part in the development of this technology is the surgical technique which will be described in this paper. The surgeons' insights into this procedure are given. These kinds of prostheses compared with the classic one, hold a promise of dramatic health and quality of life increase, together with the decrease the rejection rate.

Abstract
Human allografts for life-threatening organ failure have been demonstrated to be lifesaving and are now considered to be standard of care for many conditions. Transplantation of non-vital anatomic body parts has also been accomplished. Hand transplantation after limb loss in adults has been shown to offer some promising benefits in both functional and psychological measures in preliminary studies. It has been suggested to expand eligibility criteria to include minors, with one such operation having already been performed. With this in mind, we examine the current state of hand transplantation research in the context of available alternatives. We examine the ethics of carrying out these operations in minors, including under the protections of clinical research. We argue that children should not be considered for this surgery due to the substantial risks of immunosuppressive medication, the likelihood that the graft will need to be replaced during the patient's lifetime and the lack of significant compensatory advantages over modern prosthetics.

Abstract
BACKGROUND The purpose of this study was to identify which triple immunosuppressive protocols, currently used for vascularized composite allotransplantation in the clinic, will have the best effect on motor function recovery following nerve allograft reconstruction. METHODS Eighty-eight Lewis rats underwent a 1-cm sciatic nerve allograft transplantation and skin graft from 44 Brown-Norway rats. Group I received 0.9% isotonic saline (control); Group II, 2 mg/kg FK506; Group III, 1 mg/kg FK506 with 15 mg/kg mycophenolate mofetil (MMF); and Group IV, 2 mg/kg FK506 with 30 mg/kg MMF and prednisone. Each group consisted of 11 rats. After 12 weeks, motor function recovery was evaluated with isometric tetanic force, muscle mass, ankle contracture angle, electrophysiology, and nerve histomorphometry. Adequacy of immunosuppression was monitored with the transplanted skin graft. All data are expressed as a percentage of the contralateral side. RESULTS Isometric tetanic force showed significantly better functional recovery in all groups treated with immunosuppression compared to control. Within the immunosuppression groups no significant difference was found: 42.1 ± 6.4% (Group I), 56.1 ± 12.4% (Group II), 58.4 ± 10.7% (Group III), and 61.3 ± 11.2% (Group IV). Group IV was superior to all other groups regarding ankle contracture (P < .05) and electrophysiology (P < .001). Skin graft rejection occurred in 41 and 0% (Groups III and IV, respectively). CONCLUSIONS FK506 significantly enhanced motor recovery after allograft reconstruction. This effect was comparable between combination treatment (low-dose FK506 and MMF) and triple therapy (high-dose FK506 and MMF plus prednisolone). However, triple therapy was more effective in suppressing skin rejection.

Abstract
The idea of head transplantation appears at first as unrealistic, unethical, and futile. Here we discuss immunological considerations in human head transplantation. In a separate accompanying article we discuss surgical, ethical, and psychosocial issues concerned in body-to-head transplantation (BHT) [1]. The success of such an unusual allograft, where the donor and the recipient can reject each other, depends on prevention of complex immunologic reactions, especially rejection of the head by the body (graft-vs-host) or probably less likely, the possibility of the head rejecting the total body allograft (host-vs-graft). The technical and immunologic difficulties are enormous, especially since rapid nerve and cord connections and regeneration have not yet been possible to achieve. In this article we begin by briefly reviewing neuro-immunologic issues that may favor BHT such as the blood brain barrier (BBB) and point out its shortcomings. And we touch on the cellular and humoral elements in the brain proper that differ in some respects from those in other organs and in the periphery. Based on recent successes in vascular composite allografts (VCAs), we will elaborate on potential specific advantages and difficulties in BHT of various available immunosuppressive medications already utilized in VCAs. The risk/benefit ratio of these drugs will be emphasized in relation to direct brain toxicity such as seizure disorders, interference, or promotion of nerve regeneration, and potentiation of cerebral viral infections. The final portion of this article will focus on pre-transplant immunologic manipulation of the deceased donor body along with pretreatment of the recipient.

Abstract
BACKGROUND Hand allotransplantation was initially criticized as unethical and unlikely to succeed. The results proved to be better than anticipated, now raising the issue of whether hand transplantation is the standard of care. The purpose of this article is to outline a reasonable methodology for determining whether a surgical procedure is the standard of care, and then to apply that methodology to hand transplantation. METHODS Publications on ethics and definitions of medical (not legal) standard of care were reviewed. All hand transplantations completed in the United States were evaluated regarding their status as experimental, standard of care, or both. Then, the stakeholders, physicians, public insurers, and regulators were examined to determine whether they accepted hand transplantation as the standard of care. Utility and incremental cost-utility ratio were determined. Hand transplantation was considered the standard of care when stakeholders were using, insuring, and regulating the procedure. RESULTS The public expresses a desire for hand transplantation. A minority of surgeons consider the procedure the standard of care. Ethical committees, institutional review boards, and scholarly articles deem the procedure ethical. A series of institutions have carried out the procedure with a record of successes. Some institutions perform the surgical procedure as the standard of care. Scholarly work demonstrates beneficial outcomes. Some commercial and federal government insurers are willing to cover the cost of the procedure. Utility determination justifies the procedure. There are no incremental cost-utility ratio analysis studies that justify the procedure. CONCLUSION Hand transplantation is moving from acceptance as an ethical surgical experiment to the standard of care.

Abstract
The purpose of this study is to present the long-term outcomes of allogenic hand transplantations performed at our centre. Between January 2001 and October 2002, five allogeneic limb transplantations were performed in three patients (two bilateral forearm and one left hand transplantation). Donors and recipients were matched for blood types (ABO/Rh) and had at least two human leukocyte antigen (HLA) matches. A comprehensive rehabilitation plan integrating preoperative, intraoperative and postoperative management was developed for each patient. After 10 years, all transplantations were performed successfully without complications. As of 2014, all grafts were viable. The transplanted hands showed palmate morphology, perceived superficial pain and tactile sensations, and the static two-point discrimination ranged from 2·5 to 4·0 mm. Chronic rejection at 4 years after surgery reduced hand function in case 2. Grip strength ranged from 3 kg (case 2) to 16-18 kg (case 1) to 41-43 kg for case 3. Lifting strength ranged from 3 kg (case 2) to 21-23 kg (case 1) to 47-51 kg for case 3. They lead a completely independent life. In summary, hand function following allogeneic limb transplantation allows the ability to perform tasks of daily living.

Abstract
Transplantation of solid organs and bone marrow has become a highly acceptable and often the only available clinical solution in many situations. It has been practiced across the globe for quite a long time since the first kidney transplant in 1954. Transplantation of tissues other than these, which was termed composite tissue allotransplantation and currently as vascularised composite allotransplantation (VCA) is gaining acceptance as a solution for complex reconstructive problems. This involves the transfer of multiple types of tissue such as bone, muscle, nerve, skin and blood vessels. The advantage of these over the conventional reconstructive methods is its ability to give aesthetically and functionally superior equal composite substitute to the missing or deformed part. The composite tissues transplanted commonly include the upper extremities, face and abdominal wall. Among these, hand transplants were the first to be done and have been carried out more than any other VCA. This article reviews the current scenario of VCA especially of the hand and face, in the light of experience of the two bilateral hand transplants done recently in India.

Initial experience of dual maintenance immunosuppression with steroid withdrawal in vascular composite tissue allotransplantation. Am J Transplant 2015; 15:1421-31.

Abstract
Current immunosuppression in VCA is largely based on the experience in solid organ transplantation. It remains unclear if steroids can be reduced safely in VCA recipients. We report on five VCA recipients who were weaned off maintenance steroids after a median of 2 months (mean: 4.8 months, range 2-12 months). Patients were kept subsequently on a low dose, dual maintenance consisting of tacrolimus and mycophenolate mofetil/mycophenloic acid with a mean follow-up of 43.6 months (median = 40 months, range 34-64 months). Early and late acute rejections responded well to temporarily augmented maintenance, topical immunosuppression, and/or steroid bolus treatment. One late steroid-resistant acute rejection required treatment with thymoglobulin. All patients have been gradually weaned off steroids subsequent to the treatment of acute rejections. Low levels of tacrolimus (<5 ng/mL) appeared as a risk for acute rejections. Although further experience and a cautious approach are warranted, dual-steroid free maintenance immunosuppression appears feasible in a series of five VCA recipients.

Abstract
PURPOSE OF REVIEW Acute rejection is the most common complication after vascularized composite allotransplantation (VCA). This review provides a state-of-the-art analysis of prevention, diagnosis and treatment of acute rejection episodes and highlights recent findings with the potential to improve patient care and enhance understanding of the underlying biologic processes. RECENT FINDINGS Recent reports suggest that maintenance immunosuppression dose reduction and steroid withdrawal are realistic goals in VCA, despite the known high immunogenicity of the skin component. It appears that utilization of sentinel flaps, in-depth histological analyses and application of novel biomarkers have facilitated early diagnosis and characterization of acute rejection episodes, leading to timely institution of appropriate therapy. The successful management of the first highly sensitized face transplant recipient suggests the possibility of carefully considering these high-risk VCA candidates for transplantation. SUMMARY Acute rejection is higher in VCA than in any other organ in the field of transplantation, although most episodes are controlled by high-dose steroids and optimization of maintenance immunosuppression. Because of limitations in patient number and the duration of follow-up, the long-term safety and effectiveness of VCA remain unclear. Moreover, the tests currently used to diagnose acute rejection are of limited value. Better diagnostic tools and a better understanding of the immunologic events during acute rejection are therefore needed to improve diagnosis, treatment and outcomes of this life-changing restorative surgery.

Abstract
For several decades, prosthetic use was the only option to restore function after upper extremity amputation. Recent years have seen advances in the field of prosthetics. Such advances include prosthetic design and function, activity-specific devices, improved aesthetics, and adjunctive surgical procedures to improve both form and function. Targeted reinnervation is one exciting advance that allows for more facile and more intuitive function with prosthetics following proximal amputation. Another remarkable advance that holds great promise in nearly all fields of medicine is the transplantation of composite tissue, such as hand and face transplantation. Hand transplantation holds promise as the ultimate restorative procedure that can provide form, function, and sensation. However, this procedure still comes with a substantial cost in terms of the rehabilitation and toxic immunosuppression and should be limited to carefully selected patients who have failed prosthetic reconstruction. Hand transplantation and prosthetic reconstruction should not be viewed as competing options. Rather, they are two treatment options with different risk/benefit profiles and different indications and, hence vastly different implications.

Abstract
In September 1998 the world's first hand transplant was performed in Lyon, France. A new era in reconstructive surgery had begun. This case highlighted the potential for composite tissue allotransplantation (CTA). While CTA is not a new technique, it unifies the principles of reconstructive microsurgery and transplant surgery, achieving the goals of absolute correction of a defect with anatomically and physiologically identical tissue with none of the issues of donor site morbidity associated with autologous tissue transfer. The adoption of this technique for non-life threatening conditions to improve quality of life has generated a number of new ethical considerations. Additionally, the prominence of transplanted hands has led to much discussion around the issue of body identity and psychological assessment of potential recipients. This is fundamental to any hand transplantation programme. With the advent of hand transplantation dawning in the UK, we review the many ethical considerations that contribute to this new frontier.

Abstract
Vascularized composite allotransplantation (VCA) is a novel therapeutic option for treatment of patients suffering from limb loss or severe facial disfigurement. To date, 72 hand and 19 facial transplantations have been performed worldwide. VCA in hand and facial transplantation is a complex procedure requiring a multidisciplinary team approach and extensive surgical planning. Despite good functional outcome, courses after hand and facial transplantation have been complicated by skin rejection. Long-term immunosuppression remains a necessity in VCA for allograft survival. To widen the scope of these quality-of-life-improving procedures, minimization of immunosuppression to limit risks and side effects is needed.

Abstract
BACKGROUND Hand allotransplantation can restore motor, sensory and cosmetic functions to upper extremity amputees. Over 70 hand transplant operations have been performed worldwide, but there is little published regarding post-hand transplant rehabilitation. METHODS The Brigham and Women's Hospital (BWH) Hand Transplantation Team's post-hand transplant rehabilitation protocol is presented here. The protocol must be modified to address each transplant recipient's unique needs. It builds on universally used modalities of hand rehabilitation such as splinting, edema and scar management, range of motion exercises, activities of daily living training, electrical stimulation, cognitive training and strengthening. RESULTS The BWH hand transplant rehabilitation protocol consists of four phases with distinct goals, frequency, and modalities. (1) Pre-operative: functional assessments are completed and goals and expectations of transplantation are established. (2) Initial post-operative (post-operative weeks 1-2): hand protection, minimization of swelling, education, and discharge. (3) Intermediate (post-operative weeks 2-8): therapy aims to prevent and/or decrease scar adhesion, increase tensile strength, flexibility and function, and prevent joint contractures. (4) Late (from 8 weeks forward): maximization of function and strength, and transition to routine activities. The frequency of rehabilitation therapy decreases gradually from the initial to late phases. CONCLUSIONS Rehabilitation therapy after hand transplantation follows a progressive increase in activity in parallel with wound healing and nerve regeneration. Careful documentation of progress and outcomes is essential to demonstrate the utility of interventions and to optimize therapy protocols.

Abstract
Loss of an isolated upper limb is an emotionally and physically devastating event that results in significant impairment. Patients who lose both upper extremities experience profound disability that affects nearly every aspect of their lives. While prosthetics and surgery can eventually provide the single limb amputee with a suitable assisting hand, limited utility, minimal haptic feedback, weight, and discomfort are persistent problems with these techniques that contribute to high rates of prosthetic rejection. Moreover, despite ongoing advances in prosthetic technology, bilateral amputees continue to experience high levels of dependency, disability, and distress. Hand and upper extremity transplantation holds several advantages over prosthetic rehabilitation. The missing limb is replaced with one of similar skin color and size. Sensibility, voluntary motor control, and proprioception are restored to a greater degree, and afford better dexterity and function than prosthetics. The main shortcomings of transplantation include the hazards of immunosuppression, the complications of rejection and its treatment, and high cost. Hand and upper limb transplantation represents the most commonly performed surgery in the growing field of Vascularized Composite Allotransplantation (VCA). As upper limb transplantation and VCA have become more widespread, several important challenges and controversies have emerged. These include: refining indications for transplantation, optimizing immunosuppression, establishing reliable criteria for monitoring, diagnosing, and treating rejection, and standardizing outcome measures. This article will summarize the historical background of hand transplantation and review the current literature and concepts surrounding it.

Abstract
BACKGROUND In vascularized composite allotransplantation, multiple types of tissue are transferred from donor to recipient as a single functional unit. This technique has been performed for upper extremity, face, and abdominal wall transplants, among many others. OBJECTIVE To review the existing cases of face and upper extremity vascularized composite allotransplantation performed to date and to describe the functional outcomes and challenges associated with this new procedure. We also review the immune suppression protocols required for these procedures. METHODS A literature review was performed using PubMed and online registries where available to identify patients who have undergone upper extremity and face transplant procedures. These were compiled and cross-referenced to abstracts, conference presentations, and press releases in the media to create a list of procedures performed to date. RESULTS More than seventy patients have undergone upper extremity transplantation with very good functional outcomes routinely achieved. Twenty-five face transplants were identified that have been completed to date and details regarding patient outcome are included. One cases of human face allotransplantation with pre- and post-operative images is included as an example of what can be achieved with this technique. CONCLUSIONS Vascularized composite allotransplantation is an emerging field that provides an exciting new avenue for reconstructive procedures and achieves functional and cosmetic outcomes not previously possible with existing techniques. However, it is not without its challenges and considerable work is still required prior to widespread adoption of these new reconstructive techniques.

Abstract
BACKGROUND Limb allotransplantation is emerging as a promising solution to the loss of a limb with the development of advanced surgical techniques and new, highly effective immunosuppressive agents. METHODS We retrospectively reviewed the records of 15 hand allotransplantations in 12 patients in China which were performed from September 1999 to May 2008. RESULTS In total, there were 1 bilateral and 5 unilateral hand transplantations, 3 unilateral and 2 bilateral forearm transplantations, and 1 palm and 1 thumb transplantation. The average age of recipients was 34 ± 11.3 years (range, 19-52 years). At 1-year follow-up, all grafts were viable and with good function. Of the 15 hands transplanted, 8 are currently viable (mean follow-up, 52 ± 36.3 months; range, 16-112 months), including all 3 bilateral cases. Reasons for graft failure were rejection and failure of compliance with immunosuppressive therapy. CONCLUSIONS Long-term survival of hand transplantation with appropriate immunosuppression is feasible, and satisfactory functional results have been achieved. Careful pretransplant psychologic and social evaluation, consideration of the financial burden of long-term immunosuppressive medications, and close multispecialty collaboration is critical for good outcomes. Limb rejection was related with immunosuppression use. Further study and experience is required before hand allotransplantation can become a generally recommended treatment.

Abstract
Kv1.3-channels are critically involved in activation and function of effector memory T cells. Blocking Kv1.3-channels was investigated for its effect on skin rejection in a rat limb-transplantation-model. Animals received the Kv1.3-blocker correolide C systemically or locally as intra-graft-treatment in combination with tacrolimus. Systemic (intraperitoneal) administration of correolide C resulted in slight, but significant prolongation of allograft survival compared with untreated and placebo treated controls. In 4/6 correolide C treated animals, histology showed an intact epidermis and a mild infiltrate by day 10. High correolide C plasma trough levels correlated with prolonged allograft survival. A decrease in CD4+ and CD8+ effector memory T cells was observed in allograft skin, peripheral blood and the spleen on day 5. When applied subcutaneously in combination with systemic tacrolimus (30 days+/-anti-lymphocyte serum) detectable, but insignificant prolongation of graft survival was achieved. 2/5 animals showed an intact epidermis and a mild infiltrate until day 45. Tapering systemic tacrolimus and weaning on day 50 resulted in rejection by day 55, regardless of local correolide C treatment. Subcutaneous injection did not lead to systemic plasma levels. The Kv1.3-channel is a potential drug target worth exploring in more detail for immunosuppression in vascularized composite allotransplantation.

Abstract
PURPOSE As reconstructive transplantation emerges as an increasingly viable option for upper limb amputees, a better understanding of quality of life (QOL) outcomes is needed to evaluate the benefits and risks of the procedure from the patient perspective. METHODS To address this need, we searched PubMed (1998-2011) to characterize QOL outcomes among upper limb transplant recipients. We identified 27 articles reporting on QOL outcomes in hand transplantation. Common instruments to assess domains of QOL in hand transplantation include the Disabilities of the Arm, Shoulder, and Hand questionnaire, the Medical Outcomes Study Short Form-36, and the International Registry on Hand and Composite Tissue Transplantation's Hand Transplantation Score System. RESULTS Preliminary reports using standardized measures indicate that most hand transplant recipients described improved QOL. Several studies also qualitatively reported that recipients expressed satisfaction with cosmetic, sensory, functional, and social outcomes after transplantation. However, our review suggests that the measurement of QOL in hand transplantation is limited, although it is largely driven by QOL considerations. CONCLUSIONS This review highlights the need for improved measurement of QOL in hand transplantation. The preliminary QOL findings across published hand transplantation articles will aid in improving the future assessment of QOL in hand transplantation.

Abstract
Standardized psychological assessment of candidates for reconstructive hand transplantation (RHT) is a new approach in transplantation medicine. Currently, international guidelines and standardized criteria for the evaluation are not established. Patients suffering from the loss of a hand or an upper extremity have to cope with multiple challenges. For a selected group of patients, RHT represents an option for restoring natural function and for regaining daily living independence. The identification of at-risk patients and those requiring ongoing counseling due to poor coping or limited psychological resources are the primary focus of the psychological assessment. We have developed the 'Innsbruck Psychological Screening Program for Reconstructive Transplantation (iRT-PSP)' which utilizes a semi-structured interview and standardized psychological screening procedures and continuous follow-up ratings. Between January 2011 and October 2011, four candidates were evaluated using the iRT-PSP. Psychological impairments including social withdrawal, embarrassment, reduced self-esteem, and a depressive coping style were identified and poor quality of life was reported. The motivation for transplantation was diverse, depending on many factors such as bi- or unilateral impairment, native or accidental loss of hand, and social integration.

Abstract
BACKGROUND Mixed donor-host chimerism, established through hematopoietic cell transplantation (HCT), is a reproducible strategy for the induction of tolerance toward solid organs. Here, we ask whether a nonmyeloablative conditioning regimen establishing mixed donor-host chimerism leads to tolerance of antigenic vascularized composite allografts. METHODS Stable mixed chimerism was established in dogs given a sublethal dose (1-2 Gy) total body irradiation before and a short course of immunosuppression after dog leukocyte antigen-identical marrow transplantation. Vascularized composite allografts from marrow donors were performed after a median of 36 months (range, 4-54 months) after HCT. RESULTS All marrow recipients maintained mixed donor-host hematopoietic chimerism and accepted vascularized composite allografts for periods ranging between 52 and 90 weeks; in turn, marrow donors rejected vascularized composite allografts from their respective marrow recipients within 18 to 29 days. Biopsies of muscle and skin of vascularized composite allografts from mixed chimeras showed few infiltrating cells compared with extensive infiltrates in biopsies of vascularized composite allografts from marrow donors. Elevated levels of CD3+ FoxP3+ T-regulatory cells were found in skin and muscle of vascularized composite allografts of mixed chimeras compared with normal tissues. In mixed chimeras, increased numbers of T-regulatory cells were found in draining compared with nondraining lymph nodes of vascularized composite allografts. CONCLUSIONS These data suggest that nonmyeloablative HCT may form the basis for future clinical applications of solid organ transplantation and that T-regulatory cells may function toward maintenance of the vascularized composite allograft.

Abstract
The aim of this work is to compare disabilities of the upper limb before and after hand allograft transplantation (HAT), and to describe the side effects of immunosuppressive (IS) agents given to recipients of hand allografts. Clinical cases of HAT published between 1999 and 2011 in English, French, or German were reviewed systematically, with emphasis on comparing disabilities of the arm, shoulder and hand (DASH) scores before and after transplantation. Duration of ischemia, extent of amputation, and time since amputation were evaluated for their effect on intrinsic musculature function. Infectious, metabolic, and oncological complications because of IS therapy were recorded. Twenty-eight patients were reported in 56 clinical manuscripts. Among these patients, disabilities of the upper limb dropped by a mean of 27.6 (±19.04) points on the DASH score after HAT (P = 0.005). Lower DASH scores (P = 0.036) were recorded after secondary surgery on hand allografts. The presence of intrinsic muscle function was observed in 57% of the recipients. Duration of ischemia, extent of transplantation, and time since amputation were not associated statistically with the return of intrinsic musculature function. Three grafts were lost to follow-up because of noncompliance with immunosuppression, rejection, and arterial thrombosis, respectively. Fifty-two complications caused by IS agents were reported, and they were successfully managed medically or surgically. HAT recipients showed notable functional gains, but most complications resulted from the IS protocols.

Abstract
It has been demonstrated over the past decade that the generally achieved functional outcomes of patients after hand transplantation (HTx) are better than those of equivalent replantations. However, HTx should be performed in specialized centers with Institutional Review Board-approved transplantation programs. In Poland such requirements are fulfilled by The Subdepartment of Replantation of Limbs of St. Jadwiga Hospital in Trzebnica. A main emphasis of this subdepartment is to make the very involved process of donor recruitment, recipient screening, surgery, and postoperative treatment fully transparent. This article summarizes the experience of this center with HTx over the past 5 years.

Abstract
Hand transplantation is the most common form of modern composite tissue allotransplantation. Successful application of this technology requires a multidisciplinary approach incorporating not only skilled hand surgeons, transplant surgeons, and transplant immunologists, but also hand therapists, psychiatrists, medical specialists, anesthesiologists, and others. Functional outcomes can be life changing for properly selected candidates. Hand transplantation is becoming more common, with more centers offering this relatively new reconstructive modality. Its success depends on proper patient selection, a technically successful operation, postoperative rehabilitation, and an immunotherapy protocol that prevents rejection but has minimal or acceptable morbidity.

Abstract
Currently, more than 65 hand transplants have been performed with studies demonstrating favorable cosmetic and functional outcomes and cortical reintegration of the transplanted hand. Due to such favorable outcomes, many view hand transplant as a potential gold standard for treatment of a double amputee. However, ethical debate continues regarding risks and benefits of this nonlifesaving procedure. Clinicians, patients, and society must agree on whether hand transplantation is ethical and affordable. If a decision is made to transplant a hand, this must be performed in a dedicated center that facilitates integration of multiple specialists, ethicists, pharmacists, and rehabilitationists.

Abstract
There are many immunological challenges related to hand transplantation. Curbing the immune system's ability to effectively mount an immune response against the graft is the goal. As the various components of the immune response are defined and their mechanisms of action delineated, more specific immunosuppressive agents and protocols have been developed. Complications related to immunosuppression in hand transplant recipients are similar to incidences among solid organ recipients. With longer follow-up, the increased cardiovascular risk factors or the development of a neoplasm will likely cause mortality. Standardizing immunosuppression in hand transplantation with the long-term goal of minimization is critically needed.

Abstract
The first successful hand transplant in the modern era of reconstructive transplantation was performed in 1998. Since then, more than 65 hand and upper limb transplantations have been performed around the globe, with encouraging results. The main goal of all upper limb transplantations is to enhance the patient's quality of life. The transplant must be successfully integrated into the patient's body and self-image and the recipient should be satisfied with the recovery of sensitivity and muscle function of the new limb. To achieve these goals, a proper and thorough design of the rehabilitation regimen is of critical importance.

Abstract
Patients who have lost a hand or upper extremity face many challenges in everyday life. For some patients, reconstructive hand transplantation represents a reasonable option for anatomic reconstruction, restoring prehensile function with sensation and allowing them to regain daily living independence. The first clinical case of bilateral hand transplantation at University Hospital Innsbruck was realized on March 17th, 2000. A decade later, a total of 7 hands and forearms were transplanted in 4 patients. This article review the clinical courses of 3 bilateral hand transplant recipients and highlights psychological aspects on reconstructive hand transplantation with special regard to unilateral/bilateral transplantation.

Abstract
Hand transplantation is an elective non-life saving but quality of life-giving surgery for good candidates that is not without risk. Patient screening and selection is the most critical element to successful transplantation outcomes and cannot be overemphasized in terms of importance in the overall scheme of an active composite tissue allotransplantation (CTA) program. This article discusses the various criteria that are important in the selection of patients for CTA.

Abstract
Mild skin rejection is a common observation in reconstructive transplantation. To enlighten the role of this inflammatory reaction we investigated markers for cellular and antibody mediated rejection, adhesion molecules and tolerance markers. Forty-seven skin biopsies (rejection grade I) of human hand allografts were investigated by immunohistochemistry (CD3, CD4, CD8, CD20, CD68, C4d, LFA-1, ICAM-1, E-selectin, P-selectin, VE-cadherin, HLA-DR, IDO, and Foxp3). Expression was read with respect to time after transplant. The infiltrate was mainly comprised of CD3+T-lymphocytes. Among these, CD8+cells were more prominent than CD4+cells. CD20+B-lymphocytes were sparse and CD68+macrophages were found in some, but not all samples (approximately 10% of the infiltrate). The CD4/CD8-ratio was increased after the first year. C4d staining was mainly positive in samples at time-points later than 1 year. Adhesion molecules LFA-1, ICAM-1, E-selectin, P-selectin, and VE-cadherin were found upregulated, and for P-selectin, expression increased with time after transplant. IDO expression was strongest at 3 months-1 year post-transplant and a tendency toward more Foxp3+ cells at later time points was observed. Mild skin rejection after hand transplantation presents with a T-cell dominated dermal cell infiltrate and upregulation of adhesion molecules. The role of C4d expression after year one remains to be elucidated.

Abstract
In the past decade, more than 100 different composite tissue allotransplantation (CTA) procedures have been performed around the world including more than 50 hand and 8 facial transplants with encouraging graft survival and excellent functional outcomes. Broader clinical application of CTA, however, continues to be hampered by requirement for long-term, high-dose, multidrug maintenance immunosuppression to prevent graft rejection mediated particularly by composite tissue allograft's highly immunogenic skin component. Medication toxicity could result in severe adverse events including metabolic and infectious complications or malignancy. Notably, unlike in solid organs, clinical success is dictated not only by graft acceptance and survival but also by nerve regeneration, which determines ultimate functional outcomes. Novel strategies such as cellular and biologic therapies that integrate the concepts of immune regulation with those of nerve regeneration have shown promising results in small and large animal models. Clinical translation of these insights to reconstructive transplantation and CTA could further minimize the need of immunosuppression and optimize functional outcomes. This will enable wider application of such treatment options for patients in need of complex reconstructive surgery for congenital deformities or devastating injuries that are not amenable to standard methods of repair.

Abstract
BACKGROUND Bionic prosthetic hands are rapidly evolving. An in-depth knowledge of this field of medicine is currently only required by a small number of individuals working in highly specialist units. However, with improving technology it is likely that the demand for and application of bionic hands will continue to increase and a wider understanding will be necessary. METHODS We review the literature and summarise the important advances in medicine, computing and engineering that have led to the development of currently available bionic hand prostheses. FINDINGS The bionic limb of today has progressed greatly since the hook prostheses that were introduced centuries ago. We discuss the ways that major functions of the human hand are being replicated artificially in modern bionic hands. Despite the impressive advances bionic prostheses remain an inferior replacement to their biological counterparts. Finally we discuss some of the key areas of research that could lead to vast improvements in bionic limb functionality that may one day be able to fully replicate the biological hand or perhaps even surpass its innate capabilities. CONCLUSION It is important for the healthcare community to have an understanding of the development of bionic hands and the technology underpinning them as this area of medicine will expand.

Abstract
Overall, more than 60 hand/forearm/arm transplantations and 16 face transplantations have been performed in the past 12 years. In the European experience summarized here, three grafts have been lost in response to a vascular thrombosis (n = 1), rejection and incompliance with immunosuppression (n = 1) and death (n = 1). The overall functional and esthetic outcome is very satisfactory, but serious side effects and complications related to immunosuppression are challenges hindering progress in this field. The high levels of immunosuppression, skin rejection, nerve regeneration, donor legislation and the acceptance level need to be addressed to promote growth of this promising new field in transplantation and reconstructive surgery.

Abstract
Unilateral and bilateral hand transplantations have been performed worldwide with good mid-term functional results. An above-elbow bilateral transplantation was performed in a 29-year-old male patient from a fully HLA-mismatched donor. Alemtuzumab induction and steroid-free maintenance immunosuppression with tacrolimus and mycophenolate was used. Due to acute rejection, steroids were introduced at 6 months. Three acute rejection episodes occurred, one treated with alemtuzumab. New-onset diabetes after transplant, dyslipemia and worsening of previous high blood pressure required treatment. At 26 months post-transplantation, the patient has excellent elbow active movement, active flexion and extension of the thumb and fingers, useful sensation and a gainful job. Based on the functional results of the case reported, bilateral trans-humeral transplantation could be a viable treatment for selected bilateral above-elbow amputees.

Abstract
The immunosuppressive medications developed over the past 3 decades have paved the way for solid organ transplantation to become the treatment of choice for end-stage organ failure. At the end of the century, composite tissue transplantation in humans was performed with success using the same immunosuppressive medications and therapeutic principles. A decade later, experience from >100 cases of reconstructive transplantation have increased the knowledge, changed the view, and affected the therapeutic principles in this novel field. We herein portray the evolution of this novel type of transplant with particular reference to immunologic aspects, particularly differences between reconstructive and solid organ transplantation.
