Hand Transplantation: The Benefits, Risks, Outcomes, and Future

Crowdsourcing Attitudes and Beliefs About Upper Extremity Donation in the United States

Introduction To date, upper extremity transplantation (UET) is the most frequently performed vascularized composite allotransplantation (VCA). Perceptions regarding upper extremity donation among Americans, particularly in veterans and service members (VSMs), are largely unknown. Materials and methods We administered a one-time survey to United States (US)-resident Amazon Mechanical Turk (MTurk) workers aged ≥18 years. Descriptive statistics were used to summarize study data; frequencies and percentages were calculated for categorical variables analyzed by Fischer's exact test and using a two-tailed test assessing the statistical significance of p<0.05. Results A total of 860 respondents completed the study survey. Among these, 529 (61.5%) reported willingness to donate an upper extremity, 152 (17.7%) were undecided, and 179 (20.8%) were unwilling. A significantly higher proportion of those willing to donate were female (66.7%, p=0.009), non-Hispanic (63.9%, p=0.000), White (64.0%, p=0.004), non-religious (71.3%, p=0.001), not a VSM (62.8%, p=0.000), or non-amputees (62.9%, p=0.000). Conclusions Our survey found that being female, non-Hispanic, White, non-religious, non-VSM, or non-amputee was significantly associated with donation willingness. These findings may help guide VCA programs, organ procurement organizations, and researchers in efforts to develop targeted educational materials to broaden the public's knowledge and awareness of VCA donation to further benefit all patients in need of or desiring transplantation.

Reaching New Heights: A Comprehensive Study of Hand Transplantations in Korea after Institutionalization of Hand Transplantation Law

PURPOSE

With the revision of the Organ and Transplantation Act in 2018, the hand has become legal as an area of transplantable organs in Korea. In January 2021, the first hand allotransplantation since legalization was successfully performed, and we have performed a total of three successful hand transplantation since then. By comparing and incorporating our experiences, this study aimed to provide a comprehensive reconstructive solution for hand amputation in Korea.

MATERIALS AND METHODS

Recipients were selected through a structured preoperative evaluation, and hand transplantations were performed at the distal forearm level. Postoperatively, patients were treated with three-drug immunosuppressive regimen, and functional outcomes were monitored.

RESULTS

The hand transplantations were performed without intraoperative complications. All patients had partial skin necrosis and underwent additional surgical procedures in 2 months after transplantation. After additional operations, no further severe complications were observed. Also, patients developed acute rejection within 3 months of surgery, but all resolved within 2 weeks after steroid pulse therapy. Motor and sensory function improved dramatically, and patients were very satisfied with the appearance and function of their transplanted hands.

CONCLUSION

Hand transplantation is a viable reconstructive option, and patients have shown positive functional and psychological outcomes. Although this study has limitations, such as the small number of patients and short follow-up period, we should focus on continued recovery of hand function, and be careful not to develop side effects from immunosuppressive drugs. Through the present study, we will continue to strive for a bright future regarding hand transplantation in Korea.
