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.

Segmental fractures of the clavicle are very rare. Therefore, to date, there has not been a clear, standardized method of management of segmental clavicle fractures. Herein, two patients with a segmental fracture are described: One patient was treated conservatively, while another patient was treated operatively. Both patients showed excellent results. We discuss the various management options with a literature review.

The extension type locked metacarpophalangeal joint of the little finger is an extremely rare condition characterized by loss of flexion with little or no loss of extension. The most common cause for locking is entrapment of a strap of the ruptured palmar plate. We treated a locked metacarpophalangeal joint of the little finger due to a hyperextension injury. The mechanism of locking was a torn part of the palmar ligament that forcefully rides across the prominence of the radial condyle of the metacarpal bone together with the accessory collateral ligament. These dislocated parts of the ligament formed a constricting bundle that prevented closed reduction. Locking was released successfully by an open reduction using the dorsal approach of the metacarpophalangeal joint without complication.

Lateral eyebrow mass with primary skull lesion are rare in pediatric population. Although epidermoid cyst and dermoid cyst are the most commonly encountered skull lesions in pediatric population, Langerhans cell histiocytosis (LCH) is rarely reported. We report a case of LCH arising from the lateral eyebrow with osteolytic lesion involving the frontal bone. A 5-year-old boy was presented with a hard, fixed mass in his lateral eyebrow. Contrast magnetic resonance imaging revealed inhomogeneous enhancement of the mass with direct invasion of the frontal bone and adjacent dura mater. Under general anesthesia, linear incision at the lateral eyebrow region was made. Intraoperative evaluation revealed hard, fixed and well-defined soft tissue mass. The final extirpated mass was 2.5 x 2.4 cm in size, and was accompanied by a 1 x 1 cm sized defect on the frontal bone with intact dura mater. The surgical wound was closed primarily by a layer-by-layer fashion. Histologic examination was later performed for definite diagnosis. The histologic examination revealed abnormal proliferation of Langerhans cell with granuloma formation. Radionuclide bone scan and positron emission tomography was taken and revealed free of multi-organ involvement. At 3 months after surgery, natural looking contour at the lateral eyebrow region was observed with no tumor recurrence. Differential diagnosis of the hard and fixed mass at the lateral eyebrow region affecting the primary skull lesion from pediatric population includes epidermoid cyst, dermoid cyst and LCH. Generally, brief physical examination with plain X-ray view can be performed for clinical evaluation, but for a definite diagnosis, contrast MRI may be helpful.

Buerger's disease (thromboangiitis obliterans) is known as a segmental inflammatory vasculitis that involves the small-sized and medium-sized arteries, veins, and nerves. Most effective treatment for Buerger's disease is smoking cessation. Except for the cessation of tobacco use, surgical revascularization is available in severe ischemia and a distal target vessel. Amputation has been used as the last treatment option of the disease up to the present. Increasing limb survival and decreasing amputation rate is important. This case describes the use of spinal cord stimulation (SCS) in patient with Buerger's disease and its effect is not only the complete healing of ulcers but also amputation is not performed.

The aim of this project was to use 3D scanning data collected at incident scenes and various evidence to 1) develop surveying methods based on 3D data consisting of overall and detailed scene evidence, captured by long-range and micros-canner, which can be shared by personnel working in different fields such as forensic medicine, video analysis, physical analysis, traffic engineering, and fire investigation; 2) create digital storage for human skeletons and set the foundation for virtual anthropology; and 3) improve the credibility of 3D evidence by virtual remodeling and simulation of incident scenes and evidence to provide a basis for advanced and high-tech scientific investigation. Two complete skeletons of male and female were scanned using 3D micro-scanner. Each bone was successfully reproduced and assembled in virtual space. In addition, recreating evidence scheduled for invasive examination by creating RP (rapid prototype) was possible. These outcomes could play an important role in setting up the new field of virtual anthropology. Case-specific surveying methods were developed through analysis of 3D scanning data collected by long-range surface scanners at the scenes of vehicular accidents, falls, shootings, and violent crimes. A technique and recording method was also developed for detecting forged seals by micro-scanning the pressure exerted on the seal. Appraisal methods developed in this project could be utilized to secure 3D data of human skeletal remains and incident scenes, create a standard for application, and increase objectivity, reproducibility, and accuracy of scanning methods. We plan to develop case-specific 3D data analysis techniques to improve the credibility of analysis at the NFS and to establish a 3D data collection and analysis team.

PURPOSE: Soft tissue defect on posterior side of heel exposing Achilles tendon is vulnerable and require thin flap to improve aesthetic and functional results. Reverse superficial sural artery flap is simple and fast procedure, and it can preserves major arteries, supplies reliable constant blood, causes less donor site complication. Authors reviewed our cases and report the clinical results. MATERIALS AND METHODS: Nine cases of soft tissue defects on the posterior side of heel exposing Achilles tendon were treated with distally based superficial sural artery flap. There were 6 male and 3 female and mean age was 48.4 years. The size of flap was from 4x4 cm to 10x15 cm and mean follow-up period was 23 months. Flap survival, postoperative complications were evaluated. RESULTS: All flaps were survived completely without necrosis. There was one case of partial wound dehiscence that needed debridement and repair, and other one case had recurrent discharge that was healed after removal of calcaneal plate. All patient showed acceptable range of ankle motion. CONCLUSION: Authors suggest that the reverse superficial sural artery flap could be one of the useful treatment options for the soft tissue defect on posterior side of heel exposing Achilles tendon.

OBJECTIVES: Catechol-O-methyltransferase (COMT) plays an important role in metabolizing catecholamines, including dopamine. Also, several single-nucleotide polymorphisms (SNPs) of the COMT gene are associated with schizophrenia. Therefore, this study aimed to find the association between COMT gene SNPs and schizophrenia in Koreans. METHODS: Participants were 366 schizophrenia patients and 359 normal controls. To identify the SNPs, we performed genetic analyses in 4 SNP regions, via SNP-ITTM assays. We compared allele, genotype, and haplotype frequencies between the two groups. Moreover, we built subgroups, based on onset age, and compared individual allele and genotype frequencies among these subgroups. RESULTS: In female patients, genotype frequencies showed a significant difference in rs2020917 among the 4 SNPs (p=0.0224), but haplotype frequencies showed no such difference among the 4 SNPs between patients and controls. We noted a significant difference in rs1544325 allele frequencies according to onset age. Also, in female patients, rs1544325 allele and genotype frequencies varied significantly according to onset age. CONCLUSION: This study found no genetic association between the COMT gene's 4 SNPs and schizophrenia in Koreans. However, our findings suggest genetic components for sex-specificity and onset age in Korean schizophrenics.
