Functional outcome after hand and forearm transplantation: what can be achieved?

Vascularized Composite Allotransplantation of the Hand: A Systematic Review of Eligibility Criteria

BACKGROUND

Hand transplantation (HT) has emerged as an intervention of last resort for those who endured amputation or irreparable loss of upper extremity function. However, because of the considerable effort required for allograft management and the risks of lifelong immunosuppression, patient eligibility is critical to treatment success. Thus, the objective of this article is to investigate the reported eligibility criteria of HT centers globally.

METHODS

A systematic review of the HT literature was conducted according to Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines, using PubMed, Cochrane, Ovid/Medline, and Scopus. Program Web sites and clinicaltrials.gov entries were included where available.

RESULTS

A total of 354 articles were reviewed, 101 of which met inclusion criteria. Furthermore, 10 patient-facing Web sites and 11 clinical trials were included. The most reported criteria related to the capacity to manage the allograft posttransplantation, including access to follow-up, insurance coverage, psychological stability, and history of medical compliance. Other factors related to the impact of immunosuppression, such as active pregnancy and patient immune status, were less emphasized.

CONCLUSIONS

Because of the novelty of the field, eligibility criteria continue to evolve. While there is consensus on certain eligibility factors, other criteria diverge between programs, and very few factors were considered absolute contraindications. As the popularity of the field continues to grow, we encourage the development of consensus evidence-based eligibility criteria.

Hand Transplants, Daily Functioning, and the Human Capacity for Limb Regeneration

Unlike some of our invertebrate and vertebrate cousins with the capacity to regenerate limbs after traumatic loss, humans do not have the ability to regrow arms or legs lost to injury or disease. For the millions of people worldwide who have lost a limb after birth, the primary route to regaining function and minimizing future complications is via rehabilitation, prosthetic devices, assistive aids, health system robustness, and social safety net structures. The majority of limbs lost are lower limbs (legs), with diabetes and vascular disorders being significant causal contributors. Upper limbs (arms) are lost primarily because of trauma; digits and hands are the most common levels of loss. Even if much of the arm remains intact, upper limb amputation significantly impacts function, largely due to the loss of the hand. Human hands are marvels of evolution and permit a dexterity that enables a wide variety of function not readily replaced by devices. It is not surprising, therefore, for some individuals, dissatisfaction with available prosthetic options coupled with remarkable advances in hand surgery techniques is resulting in patients undertaking the rigors of a hand transplantation. While not “regeneration” in the sense of the enviable ability with which Axolotls can replace a lost limb, hand transplants do require significant regeneration of tissues and nerves. Regaining sophisticated hand functions also depends on “reconnecting” the donated hand with the areas of the human brain responsible for the sensory and motor processing required for complex actions. Human hand transplants are not without controversy and raise interesting challenges regarding the human regenerative capacity and the status of transplants for enabling function. More investigation is needed to address medical and ethical questions prior to expansion of hand transplants to a wider patient population.

Addressing common orthopaedic calamities with microsurgical solutions

Reconstructive microsurgery has been an essential aspect of orthopaedic surgery and extremity reconstruction since the introduction of the operating microscope in the mid-20^th century. The reconstructive ladder ranges from simple healing by secondary intention to complex procedures such as free tissue transfer and vascularized composite allotransplantation. As orthopaedic surgery has evolved over the past 60 years, so too have the reconstructive microsurgical skills that are often needed to address common orthopaedic surgery problems. In this article, we will discuss a variety of complex orthopaedic surgery scenarios ranging from trauma to infection to tumor resection as well as the spectrum of microsurgical solutions that can aid in their management.

Hand Transplantation-Risks and Benefits

Composite tissue allotransplantation (CTA) is the culmination of progress in transplantation, allowing the reconstruction of the hand in amputees. Worldwide, more than 100 procedures have been performed. The aim of this work was to understand the hand allotransplantation approach, making known current aspects, risks, and benefits. A PubMed research was realized between October 2018 and March 2019, including terms like "Hand transplantation" AND "Composite tissue allotransplantation," "Hand transplantation" AND "Functional outcomes," "Hand transplantation" AND "Immunosuppression," "Hand prosthetics," "Hand Transplantation" AND "Ethics." There were included papers between 1995 and 2018, with English language, amputee human adults, systematic reviews, and clinical studies. Seventy-two papers were fully evaluated. There are technical aspects that influence the procedure like team coordination or surgical technique. It requires a long-life treatment, which has risks such as toxicity or infections. However, it allows the recovery of fine movements, and independence, to perform detailed tasks. The indications must be carefully considered, because some patients benefit from the use of prosthesis. CTA has become an option for amputees so it is important to do more research, to determine the benefits of this procedure. It is not considered a life-saving procedure, so there is an ethical debate because of the risks.

An Individualized Physiotherapy and Rehabilitation Program for Bilateral Hand Transplantations

METHODS

This article describes a rehabilitation program and the long-term results after its application in 2 double-hand transplantation patients after 9- and 4-year follow-up periods. A personal rehabilitation program was planned to commence as early as possible after postoperative patient stabilization. Splinting, edema, positioning, passive and active joint movements, daily life activity modification and education, and occupational therapy were also emphasized.

RESULTS

Positioning, edema, and passive joint movements were started in the acute phase. Strengthening and exercises were continued for 8 weeks and later for functional gains and adaptation to daily living activities. Subjective and overall results were quite satisfactory. The Hand Transplantation Score System, Disabilities of the Arm Shoulder and Hand, Semmes Weinstein Monofilaments, sensory tests, and modified Kapandji index improvements were all within good acceptable ranges. Although rapid recovery and functional development were observed in the first 4 years, these are still continuing at the time of writing.

DISCUSSION

The most important determining factors in the success of rehabilitation are to return to daily life and the ability to acquire functional skills. Long-term follow-up of the patients in this study showed that they were able to return to their independent daily lives and that external assistance decreased to a minimum.

Long-term outcome after hand and forearm transplantation - a retrospective study

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.

Measuring Functional Outcomes After Bilateral Vascularized Composite Hand Allotransplantation: A Report of 3 Cases

PURPOSE

Currently, numerous assessment tools are available to measure functional outcomes after bilateral hand transplantation. The purpose of this article is to present our experience utilizing quantitative assessment tools for functional evaluation and to describe our results after bilateral hand transplantation.

METHODS

A single surgeon's experience with bilateral hand transplantation from 2011 to 2016 was retrospectively reviewed. Three bilateral hand transplantations were performed in 2 adults and 1 child. A minimum 2-year follow-up evaluation was available. For the adult patients, postoperative outcome measures included patient-reported pain and disability scores, return of sensation, muscle strength, range of motion, and return to work/activities of daily living, the Hand Transplant Scoring System (HTSS), the Sollerman hand function test, and complications. For our pediatric patient, postoperative outcome measures included the Functional Independence Measure for children (WeeFIM) scale, a functional independence measure for children, the 9-Hole Peg Test, the Box and Block test, and complications.

RESULTS

Our 2 adult patients were age 28 and our pediatric patient was age 8 at transplantation. Follow-up ranged from 2 to 7 years. The functional assessments were performed over a period from 11 to 48 months after transplantation. Both adult patients achieved functional independence and the HTSS, Short Form-36 Health Score (SF-36), DASH, and Sollerman tests demonstrated sequential improvement compared with pretransplantation scores assessed with the use of prostheses. Our pediatric patient demonstrated improvement in his Box and Block test score for each hand at sequential visits after transplantation. His 9-Hole Peg Test demonstrated improvement, and his WeeFIM assessment at 20 months indicated a greater level of independence.

CONCLUSIONS

Patient-reported outcomes and the Sollerman test when used in addition to the HTSS appear to reflect functional improvement in adult patients after bilateral hand transplantation. Although children pose a unique challenge with functional assessment, we found the WeeFIM assessment, 9-Hole Peg Test, and the Box and Block test helpful in evaluating functional outcomes in our pediatric patient.

Graft vasculopathy in upper extremity allotransplantation: Results of a retrospective high-resolution ultrasonographic study

Graft vasculopathy (GV) is the most severe pathologic change of chronic rejection in vascularized composite allotransplantation. Since 2012, the intimal media thickness (IMT) of radial and ulnar arteries was annually monitored by high-resolution ultrasonography in seven bilateral upper extremity transplant (UET) patients. We also investigated the IMT of seven matched healthy subjects (controls). No significant difference between IMT values of controls and UET patients was found. The median IMT values of recipient radial and ulnar arteries were 0.23 mm and 0.25 mm, respectively, while the median IMT values of grafted radial and ulnar arteries were 0.27 mm and 0.30 mm, respectively. There was a statistically significant difference in the IMT values of the grafted and recipient ulnar arteries (p = .043), but this difference was no longer significant when patient #2 was excluded. He showed a significant difference between recipient and grafted arteries and significantly higher IMT values (p = .001) of his grafted arteries compared with those of all transplanted patients. This patient developed GV leading to graft loss 11 years after the transplantation. In conclusion, this study showed a significant IMT increase in an UET recipient who developed GV.

Bilateral Proximal Forearm Transplantation: Case Report at 7 Years

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.

Functional Outcome Scores With Standard Myoelectric Prostheses in Below-Elbow Amputees

OBJECTIVE

The aim of the study was to report normative outcome data of prosthetic hand function in below-elbow amputees using four different objective measurements closely related to activities of daily living.

DESIGN

Seventeen patients who underwent prosthetic fitting after unilateral below-elbow amputation were enrolled in this study. Global upper extremity function was evaluated using the Action Research Arm Test, Southampton Hand Assessment Procedure, the Clothespin-Relocation Test, and the Box and Block Test, which monitor hand and extremity function.

RESULTS

The patients achieved a mean ± SD Action Research Arm Test score of 35.06 ± 4.42 of 57. The mean ± SD Southampton Hand Assessment Procedure score was 65.12 ± 13.95 points. The mean ± SD time for the Clothespin-Relocation Test was 22.57 ± 7.50 secs, and the mean ± SD score in the Box and Block Test was 20.90 ± 5.74.

CONCLUSIONS

In the current economic situation of health care systems, demonstrating the effectiveness and necessity of rehabilitation interventions is of major importance. This study reports outcome data of below-elbow amputees and provides a useful guide for expected prosthetic user performance.

The functional assessment and rehabilitation programme of the UK hand and upper limb transplant service

Introduction

Hand and upper limb transplants are becoming internationally recognised as an effective treatment to improve function and quality of life in carefully selected patients. A comprehensive functional assessment and rehabilitation programme are an essential component of the multi-disciplinary assessment and treatment approach. Although there is an increasing body of published data on the surgical techniques and outcomes following hand transplant, little exists in the literature to guide the hand therapist.

Method

The pre-transplant functional assessments and rehabilitation programme provided for patients undergoing hand transplantation in the UK are described and critically analysed. The UK programme is based on that provided in Lyon, France, but adapted to suit the resources and structure of the UK National Health Service.

Results

Twelve patients have received a functional assessment as part of the multi-disciplinary hand transplant assessment process, with the loss of autonomy a key reason for patients seeking hand transplant. Six of these patients have received hand transplants, with patients more than one year post-transplant having achieved good and fair outcomes according to the Hand Transplantation Score System.

Conclusions

Although hand and upper limb transplant surgery is innovative, the therapy provided is based on the fundamental principles of good communication, accurate assessment and delivery of a bespoke rehabilitation programme; values which are common to all areas of hand therapy practice. A future study reporting the long-term outcomes of patients following hand transplant in the UK is needed to allow the effectiveness of the programme to be evaluated.

Evolving ethics, policy and reimbursement issues of vascularized composite allotransplantation: Symposium summary

In this article, we present a report from a national meeting titled, “Evolving Issues of Vascularized Composite Allotransplantation—A Symposium on Ethics, Policy, and Reimbursement Issues,” which convened in September 2017. We discuss the maturation of vascularized composite allotransplantation from an emerging technology to becoming an extension of clinical practice for select patients with complex reconstructive needs. Viewpoints and action items were presented by and discussed among the 70+ clinicians, researchers, policymakers, ethicists, healthcare administrators, and third-party payers who attended the symposium with the goals of implementing a collaborative roadmap for vascularized composite allotransplantation growth, evaluation, and sustainability by establishing a unified plan to help address concerns of the public, policymakers, and healthcare finance. We review the current status of vascularized composite allotransplantation in clinical practice and summarize symposium discussions regarding ethical considerations, reimbursement, payer strategies, and standardization of data collection.

Prosthetic Rehabilitation and Vascularized Composite Allotransplantation following Upper Limb Loss

BACKGROUND

Upper limb loss is a devastating condition with dramatic physical, psychological, financial, and social consequences. Improvements in the fields of prosthetics and vascularized composite allotransplantation have opened exciting new frontiers for treatment and rehabilitation following upper limb loss. Each modality offers a unique set of advantages and limitations with regard to the restoration of hand function following amputation.

METHODS

Presented in this article is a discussion outlining the complex considerations and decisions encountered when determining patient appropriateness for either prosthetic rehabilitation or vascularized composite allotransplantation following upper limb loss. In this review, the authors examine how psychosocial factors, nature of injury, rehabilitation course, functional outcomes, and risks and benefits may affect overall patient selection for either rehabilitative approach.

RESULTS

This review summarizes the current state of the literature. Advancements in both prosthetic and biological strategies demonstrate promise with regard to facilitating rehabilitation following upper limb loss. However, there remains a dearth of research directly comparing outcomes in prosthetic rehabilitation to that following upper extremity transplantation.

CONCLUSIONS

Few studies have performed a direct comparison between patients undergoing vascularized composite allotransplantation and those undergoing prosthetic rehabilitation. Upper extremity transplantation and prosthetic reconstruction should not be viewed as competing options, but rather as two treatment modalities with different risk-to-benefit profiles and indications.

First two bilateral hand transplantations in India (Part 3): Rehabilitation and immediate outcome

Introduction

This report covers the strategies adopted for rehabilitation for the first and second dual hand transplants performed in India.

Materials and Methods

The team, under a trained physiatrist, including physiotherapy and occupational therapy personnel, was involved in the management of both these patients. The management protocol was developed considering previous reports as well as our management strategies in the rehabilitation of the replanted hands. The involvement of the team with the patients started in the 1st week itself and continued on a daily basis for the entire year.

Results

Outcome analysis was performed at 6 months and 1 year using the disability of shoulder and hand evaluation and hand transplant scoring system. Functional magnetic resonance imaging was done at the end of 1 year to assess the cortical integration of the transplanted hand.

Conclusion

Despite more than 110 hands being transplanted worldwide, hand transplant remains an experimental procedure. It is still not considered the "standard of care" for hand amputees. Outcome analyses performed worldwide do indicate that the procedure can provide a substantial improvement in the quality of life for the hand amputee, especially the bilateral amputees.

Outcomes after hand and upper extremity transplantation

Hand and upper extremity transplantation (HUET) has emerged as the most frequently performed reconstructive procedure in the burgeoning field of vascularized composite allotransplantation (VCA). VCA refers to a form of transplant with multiple tissue types that represents a viable treatment option for devastating injuries where conventional reconstruction would be unable to restore form and function. As hand transplantation becomes increasingly more common, discussions on advantages and disadvantages of the procedure seem to intensify. Despite encouraging functional outcomes, current immunosuppressive regimens with their deleterious side-effect profile remain a major concern for a life-changing but not life-saving type of transplant. In addition, a growing number of recipients with progressively longer follow-up prompt the need to investigate potential long-term sequelae, such as chronic rejection. This review will discuss the current state of HUET, summarizing outcome data on graft survival, motor and sensory function, as well as immunosuppressive treatment. The implications of these findings for VCA in terms of achievements and challenges ahead will then be discussed.

Functional and Psychosocial Outcomes of Hand Transplantation Compared with Prosthetic Fitting in Below-Elbow Amputees: A Multicenter Cohort Study

Background

Hand-transplantation and improvements in the field of prostheses opened new frontiers in restoring hand function in below-elbow amputees. Both concepts aim at restoring reliable hand function, however, the indications, advantages and limitations for each treatment must be carefully considered depending on level and extent of amputation. Here we report our findings of a multi-center cohort study comparing hand function and quality-of-life of people with transplanted versus prosthetic hands.

Methods

Hand function in amputees with either transplant or prostheses was tested with Action Research Arm Test (ARAT), Southampton Hand Assessment Procedure (SHAP) and the Disabilities of the Arm, Shoulder and Hand measure (DASH). Quality-of-life was compared with the Short-Form 36 (SF-36).

Results

Transplanted patients (n = 5) achieved a mean ARAT score of 40.86 ± 8.07 and an average SHAP score of 75.00 ± 11.06. Prosthetic patients (n = 7) achieved a mean ARAT score of 39.00 ± 3.61 and an average SHAP score of 75.43 ± 10.81. There was no significant difference between transplanted and prosthetic hands in ARAT, SHAP or DASH. While quality-of-life metrics were equivocal for four scales of the SF-36, transplanted patients reported significantly higher scores in “role-physical” (p = 0.006), “vitality” (p = 0.008), “role-emotional” (p = 0.035) and “mental-health” (p = 0.003).

Conclusions

The indications for hand transplantation or prosthetic fitting in below-elbow amputees require careful consideration. As functional outcomes were not significantly different between groups, patient’s best interests and the route of least harm should guide treatment. Due to the immunosuppressive side-effects, the indication for allotransplantation must still be restrictive, the best being bilateral amputees.

Hand Transplantation Versus Hand Prosthetics: Pros and Cons

Composite tissue transplantation and new developments in the field of prosthetics have opened new frontiers in the restoration of function among upper limb amputees. It is now possible to restore hand function in affected patients; however, the indications, advantages, and limitations for either hand transplantation or prosthetic fitting must be carefully considered depending on the level and extent of the limb loss. Hand transplantation allows comprehensive hand function to be restored, yet composite tissue transplantation comes with disadvantages, making this method a controversial topic in the hand surgical community. Alternatively, prosthetic limb replacement represents the standard of care for upper limb amputees, but results in the known limitations of function, sensation, and usage. The indication for hand transplantation or prosthetic fitting strongly depends on the level of amputation, as well as on the extent (unilateral/bilateral) of the amputation. In this review, we discuss the advantages and disadvantages of hand transplantation and prosthetic replacement for upper limb amputees in general, as well as in regard to the different levels of amputation.

Use of Video Clips to Assess the Outcomes of Bilateral Hand Transplantation

Supplemental Digital Content is available in the text.

Given the initial success of hand transplantation, there has been increased interest in determining functional independence and activities of daily living after hand transplantation. However, the metrics and methodologies used to study these outcomes have not yet been standardized. The goal of this article was to assess the role of video clips in assessing the outcomes of bilateral hand transplantation. We have performed 3 bilateral hand transplantations at our institution. Video clips were taken at standardized time points on our index bilateral hand transplantation patient, and the patient sent multiple home-video clips demonstrating new aspects of function when these improvements have occurred. The index patient demonstrated functional independence and activity of daily living performance without assistance in video clips ranging from 9 months to 2.5 years posttransplantation. He completed the 9-hole peg test with his left hand at 9 months follow-up and with both the hands by 1.5 years. His own video clips demonstrated his ability to perform spontaneous tasks including lawn mowing, driving and swimming. In our experience, the video tools aid in assessing outcomes of hand transplantation and may be incorporated along with multiple objective scoring tests. They can also be used to generate additional standardized tests for functional assessment and may allow retrospective grading as new scoring systems are developed.

The health technology assessment of the compulsory accident insurance scheme of hand transplantation in Switzerland

Recently the decision-making committee of the compulsory Swiss accident insurance scheme needed to make a basic decision as to whether to fund hand transplantation under that scheme or not. A Health Technology Assessment was commissioned to inform decision-making and gain experience with applicability of the method. The following were main findings from various domains. Compared with prosthesis fitting, the outcome of hand transplantation is satisfactory for function and sensibility. Complications due to immunosuppression are frequent, sometimes severe and potentially life-shortening. The direct medical costs over the entire life span calculated for a 35-year-old unilaterally amputated base case patient were CHF 528,600 (EUR 438,500) higher than for a prosthesis. There are challenging ethical, legal and organizational issues. The committee decided not to reimburse hand transplantation for ethical reasons. The Health Technology Assessment has been shown to be a useful tool for decision-making in the context of Swiss accident insurance.

Allogeneic hand transplantation and rehabilitation of hand function: a 10-year follow-up study

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.

A new hand enhances life for quadruple amputee: A single case study

This single case study discusses the various challenges and rehabilitation of Australia’s first hand transplant from the hand therapy perspective. The recipient was a 65-year-old quadrimembral amputee male following overwhelming pneumococcal sepsis. Key issues included cognitive relearning following the four-year loss of cortical feedback, extrinsic muscle retraining, poor coordination and functional limitations as a result of intrinsic dennervation, and an insensate hand. Distinct clinical differences from total hand replantation included consideration of immunosuppression drugs and potential rejection episodes. Although the patient was highly motivated, a client-centred approach was critical for ongoing commitment to the intensive long-term rehabilitation programme. The recipient’s progress in the first two and a half years has been impressive with achievement of many personal goals including eating, drinking, writing, driving and lawn bowls. His results, recorded on the International Hand Transplant Registry, showed superior measurements in areas of the DASH, grip strength, and TAM of forearm, wrist, and fingers.

Composite tissue transplantation

Composite tissue transplantation is an emerging new era in transplant medicine and has become a viable reconstructive option for patients with large and devastating tissue defects. Advances in microsurgical techniques, transplant immunology and the development of potent immunosuppressive agents have enabled the realization of such types of transplants. Over the past decade, a rapidly growing number of face and upper extremity transplantations have been performed worldwide with highly encouraging outcomes. However, despite the fact that surgical, immunological and functional results are highly encouraging, the need for long-term and high-dose immunosuppression to enable graft survival and to treat/reverse acute skin rejection episodes remains a pace-limiting obstacle towards wide spread application. In this chapter we review the history and development of this novel field, the functional and immunological outcomes based on the world experience, unique biological features of such transplants, mechanisms and treatment protocols for acute skin rejection, as well as novel concepts for immune modulation and tolerance induction.

Quality of life considerations in upper limb transplantation: review and future directions

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.
