Purpose: Treatment options for distal radius malunion with dorsal angulation include open-wedge osteotomy using a volar approach or closed-wedge osteotomy. An advantage of open-wedge osteotomy is that it preserves the length of the radius; however, it often requires bone grafting and presents difficulties in achieving reduction. In contrast, closed-wedge osteotomy makes correction easier, but it requires ulnar shortening osteotomy. Therefore, in this study, we propose an effective surgical method that compensates for the disadvantages of both techniques by using half-wedge osteotomy and rotational placement. Methods: This study presents five cases of distal radius corrective osteotomy and ulnar shortening osteotomy performed at our institution using half-wedge osteotomy and rotational placement for distal radius malunion between 2017 and 2021. Surgical efficacy was evaluated by assessing radiographic changes, visual analog scale scores, and the quick Disability of the Arm, Shoulder, and Hand score postoperatively. Results: The bone union was achieved in all cases, and computed tomography scans performed 6 months postoperatively showed ongoing bone healing. Postoperative dorsal tilt was restored to the normal range, and the clinical scores improved. Conclusion Half-wedge osteotomy and reverse repositioning for dorsal malunion distal radius are effective treatments, as they facilitate the correction of malunion, reduce the need for ulnar shortening length, and eliminate the need for bone grafting from the iliac crest.

Purpose: This study aimed to provide the descriptive statistics regarding the injury epidemiology of Korean professional basketball players. Methods: In this study, athlete exposures (AEs) and time exposures (TEs) were collected from the 38 basketball players (17 women) who participated in the 2019–2020 regular season. Injury rate (IR) and 95% confidence interval (CI) were calculated. Results: A total of 35 injuries were reported. The overall rate of injury was 5.65 per 1,000 AEs and 0.06 per 1,000 TEs. Approximately 65.7% of all the injuries occurred during the official games, with lower limb injuries accounting for about 57.1% of all the injuries. Ankle was the most frequently injured body area (25.7%) with a IR of 1.45 per 1,000 AEs. Sprain accounted for the largest portion with 54.3% overall, followed by strain, contusion and cartilage damage. The most common cause of injuries was contact with another athletes (37.2%), and the recurrence of past injuries (20.0%) also accounted for a high proportion. Conclusion Korean professional basketball players experience a high rate of injuries occurring during official games.Ankle sprains were the most common ones. Contact-caused injuries accounted for the highest portion.

Objective: This study aimed to investigate characteristics of suicide attempters who visited the emergency department to identify physical risk factors and rescue factors, and to assess the impact of social distancing during coronavirus disease-2019 (COVID-19) on suicide attempters. Methods: The study utilized data from the medical records of suicide attempters who visited the Bucheon Regional Emergency Medical Center of Soonchunhyang University Bucheon Hospital for 3 years from 2019 and the consultation records of the Life Love Crisis Response Team. This cross-sectional study analyzed changes in risk and rescue characteristics of suicide attempters before, during, and after the implementation of social distancing policies. The Risk-Rescue Rating Scale (RRRS) was used to assess the risk and rescue of suicide attempters. Results: During the implementation of social distancing, the RRRS for physical risk demonstrated a 1.67-fold increase in low-risk cases, which further escalated to a 2.39-fold increase post-implementation compared to the period prior to social distancing. Additionally, the RRRS indicated that behaviors became 1.44 times less rescued amid social distancing, with increased tendencies to conceal the act to evade detection and a reluctance to seek help (p<0.001). Conclusion Our findings indicate that it is important to develop suicide prevention programs for low-risk suicide attempts and to identify the characteristics of suicide attempts that occur during large-scale social isolation, such as infectious diseases, in order to develop strategies for suicide prevention in the future.

Reconstructive options for multidigit or soft tissue defects of the hand are varied, yet complex hand defects remain particularly challenging. These cases often necessitate microvascular reconstruction using osteocutaneous free flaps to achieve functional limb salvage. This paper presents two cases of osteocutaneous lateral arm free flap surgery performed at our institution, demonstrating the efficacy of this technique in managing complex hand defects. One case involved a severe crushing injury on an index finger with only the ulnar neurovascular bundle remaining, and the other involved a crushing injury on the first web space with severe comminution of the first metacarpal bone. After an emergency simple debridement, reconstructive surgery using the osteocutaneous lateral arm free flap was performed a few days later. Both cases healed without necrosis. Although both patients lost interphalangeal joint function, they were able to maintain grasping function and finger length without amputation. The osteocutaneous lateral arm free flap is an effective reconstruction method for addressing small to moderate-sized segmental bone and soft tissue defects of the hand caused by trauma. This procedure can be conveniently performed in a single session under regional anesthesia.
