Process of Obtaining Social Consensus and 3-Year Functional Outcomes of the First Hand Allotransplantation in Korea.

BACKGROUND: On February 2, 2017, the surgical team of ten board-certified hand specialists of W Hospital in Korea successfully performed the nation's first hand transplantation at Yeungnam University Medical Center (YUMC). This paper reports on the legal, financial, and cultural hurdles that were overcome to open the way for hand transplantation and its functional outcomes at 36 months after the operation. METHODS: W Hospital formed a memorandum of understanding with Daegu city and YUMC to comply with government regulations regarding hand transplantation. Campaigns were initiated in the media to increase public awareness and understanding. With the city's financial and legal support and the university's medical cooperation, a surgical team performed a left distal forearm hand transplantation from a brain-dead 48-year-old man to a 35-year-old left-handed man. RESULTS: With this successful allotransplantation, the Korean Act on Organ Transplantation has now been amended to include hand transplantation. Korean national health insurance has also begun covering hand transplantation. Functional outcome at 36 months after the operation showed satisfactory progress in both motor and sensory functions. The disabilities of the arm, shoulder, and hand score were 23. The final Hand Transplantation Score was 90 points. Functional brain magnetic resonance imaging shows significant cortical reorganization of the corticospinal tract, and reinnervation of intrinsic muscle is observed. CONCLUSIONS: Hand transplantation at the distal forearm shows very satisfactory outcomes in functional, aesthetical, and psychological aspects. Legal and financial barriers against hand transplantation have long been the most burdensome issues. Despite this momentous success, there have been no other clinical applications of vascularized composite allotransplantation due to the limited acceptance by Korean doctors and people. Further public education campaigns for vascularized composite allotransplantation are needed to increase awareness and acceptance.

Delayed and suspended replantation for complete amputation of digits and hands.

PURPOSE: To analyze the clinical outcome for delayed or suspended replantation of complete amputations of digits or hands, or both. METHODS: We analyzed 20 cases involving 28 digital and 4 hand amputations that underwent delayed or suspended replantation. In 15 cases of single-digit amputation, patients underwent delayed replantation the morning following amputation. With amputation of multiple digits, bilateral digits, or the hand, the important digits or dominant hand underwent immediate replantation, and we suspended the surgeries for the residual digits or non-dominant hand, or both, until the next morning. We then evaluated the mean warm and cold ischemic time for the operations, graft survival rates, and clinical outcomes. The mean follow-up period was 26 months. We evaluated the clinical results using the criteria of Chen. RESULTS: The mean warm and cold ischemic times in 15 cases of delayed replantation were 2 hours 4 minutes and 7 hours 21 minutes, respectively. In 8 cases of suspended replantation, the mean warm and cold ischemic times in the first operation were 5 hours 54 minutes and 2 hours 36 minutes, respectively. In the second operation, the cold ischemic time averaged 15 hours 48 minutes. In this series, 24 of 28 digits and all 4 hands survived. Total survival incidence in both delayed and suspended replantation was 88%, not statistically different from the overall survival incidence in 711 cases of immediate replantation during the same period (84%). In delayed replantation, we observed an excellent result with 6 digits and a good result with another 6 digits. In suspended cases, we observed a good result with one multiple-digit and one hand procedure and we obtained a fair result in 3 multiple-digit and 2 hand replantation procedures. CONCLUSIONS: Delayed and suspended replantations demonstrate results comparable to immediate replantation regarding graft survival and clinical outcome. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

The Expanded Application of the Acellular Dermal Matrix: Traumatic Nail Bed Defect of the Digits.

Reconstruction of traumatic nail bed defects in the digits is a frequently encountered procedure, yet often presents many challenges. In such scenarios, staged procedures may be required with significant limitations in shape and increased donor site morbidity, particularly when multiple defects are present. In this study, we introduce a simple method for the reconstruction of nail bed defects using an acellular dermal matrix (ADM). The study involved 19 digits with nail defects, which underwent reconstruction using an ADM graft. The surgical procedure was performed on all patients on the day of injury, after which they were promptly discharged. The dimensions of the defect ranged from 0.5 × 0.5 cm to a maximum of 2 × 3 cm (average, 0.9 × 1.4 cm). Final examinations were performed at postoperative 5-11 months (average, 6.6 months). All ADM grafts were successfully taken. Nail growth was observed at an average of 4 months after surgery in the treated finger. The surgical results were retrospectively evaluated using the Zook criteria. Outcomes were "excellent" in 11 patients (57.9%), "very good" in five patients (26.3%), "good" in two patients (10.5%), and "fair" in one patient (5.2%). The expanded application of ADM explored in this study illustrates a straightforward method for the reconstruction of traumatic nail bed defects, providing effective results in a single stage without incurring donor site morbidity.

The fate of delayed revascularization for neglected vascular injury of incompletely amputated digits and hands.

We report the fate of neglected vascular injury in cases of incomplete amputation of the digits and hand after delayed revascularization. Twelve patients underwent primary bone fixation, tendon or skin repair for hand injuries without vessel repair despite ischaemic findings. There was discoloration or necrosis of the fingertips during follow-up examination and the patients were referred to us for treatment. The mean warm ischaemic time was 53 hours (range 17-120). Delayed revascularization was performed with end-to-end anastomosis of the digital arteries in eight and vein graft in four cases. Digital nerves were repaired in four cases and flexor tendons in two cases. Of the 12 cases, eight cases showed complete survival. However, in four patients, complete necrosis of the fingers occurred, with one finger surviving partially. Revision amputation was performed in the four cases where necrosis occurred. We conclude that neglected vascular injury associated with incomplete amputation of digits and hands can be overcome in some patients by delayed revascularization even after prolonged warm ischaemic time. Level of evidence: IV.

Hand and Wrist Injuries in Golfers and Their Treatment.

A thorough understanding of the swing phases and mechanisms of injury in golf allows accurate diagnosis, treatment, and future prevention of injuries. Recommended initial treatment starts with cessation of practice to rest the wrist, a splint or orthotic brace, and nonsteroidal antiinflammatory drug medication with corticosteroid injection and swing modification. Pisiform excision is the best treatment of the most severe chronic cases of pisiform ligament complex syndrome. Delayed diagnosis of hook of hamate fracture may lead to complications, including flexor tendon rupture. Prompt surgical resection is recommended to hasten return to sport and to prevent further complications.

Management of complications relating to finger amputation and replantation.

There are many options in the management of fingertip or finger amputations. Injudicious revision amputation may cause complications. These complications can be prevented by tension-free closure of the amputation stump or primary coverage with appropriate flap. Replantation is the best way to keep the original length and maintain digital function. Patent vein repair or venous drainage with bleeding until neovascularization to the replanted part is the key to successful replantation. Prevention and management of complications in replantation and revision amputation increase patients' satisfaction and decrease costs. Research is needed to define new indications of replantation for digital amputation.

Protective effect of a mixture of Aloe vera and Silybum marianum against carbon tetrachloride-induced acute hepatotoxicity and liver fibrosis.

The hepatoprotective effects of ACTIValoe N-931 complex, a mixture of Aloe vera and Silybum marianum, against acute and chronic carbon tetrachloride (CCl(4))-induced liver injuries were investigated. Acute hepatotoxicity was induced by intraperitoneal injection of CCl(4) (50 microl/kg), and ACTIValoe N-931 complex at 85, 170, and 340 mg/kg was administered orally 48, 24, and 2 h before and 6 h after injection of CCl(4). Hepatotoxicity was assessed 24 h after CCl(4) treatment. Liver fibrosis was induced by intraperitoneal injection of CCl(4) for 8 weeks (0.5 ml/kg, twice per week), and mice were treated with ACTIValoe N-931 complex at 85, 170, or 340 mg/kg once a day (p.o.). In both acute hepatotoxicity and liver fibrosis, serum aminotransferase levels and lipid peroxidation were increased and the hepatic glutathione content was decreased. These changes were prevented by ACTIValoe N-931 complex. The ACTIValoe N-931 complex attenuated the increase in tumor necrosis factor-alpha (TNF-alpha), and inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2), mRNA expressions in acute hepatotoxicity. In antifibrotic experiments, tissue inhibitor of metalloprotease-1 (TIMP-1) mRNA expression was attenuated by treatment with ACTIValoe N-931 complex. The ACTIValoe N-931 complex decreased the hepatic hydroxyproline content and the transforming growth factor-beta1 levels. Our results suggest that the ACTIValoe N-931 complex has hepatoprotective effects in both acute and chronic liver injuries induced by CCl(4).
