In acute hand injury, there are sometimes hattened neglected or overlooked vascular injury by primary operators. The authors evaluated the final results and prognosis after secondary revascularization. In eight cases, the authors performed secondary revascularization after prolonged warm ischemia. Five fingers in five cases among them were successfully survived and three cases finally necrosed. The mean warm ischemic time was 56.1 hours. In revascularization procedures, end-to-end artery anastomosis was possible in six cases. In two cases, vein graft was needed to anastomose digital artery, which resulted in complete survival of the fingers. In all three cases, revision amputation of the fingers was done. In acute complex hand injury, the importance of evaluation of the vascular injury can not be overemphasized. The necessity of the early secondary revascularization as well as serious consequence caused by misdiagnosis of vascular injury should be aware.

From 1994-2001, 25 mutilated digits were reconstructed with immediate toe-to-hand transfer in acute hand injury in 21 patients. There were 15 cases of great toe-to-hand transfer(partial great toe transfer 8 cases, modified wrap-around procedure 2 cases, and trimmed great toe transfer 2 cases) for thumb reconstruction, 2 cases of second toe transfer for index reconstruction, and 4 cases of simultaneous two toe-to-hand transfer(great toe & second toe transfer 1 case, bilateral second-toe transfer 2 cases, combined second & third toe transfer 1 case) for reconstruction of multiple digit amputations. Two cases of emergency exploration(2/25, 8%) were successfully salvaged. The incidence of emergency exploration and postoperative infection was not significantly different from that of the elective toe-to-hand transfer cases. Duration of industrial insurance coverage was 225 days, which is much shorter than that of elective cases. Among 43% of patients maintained their original job even after injury and immediate toe-to-hand transfer. The subjective satisfaction self- assessment scores of aesthetic appearance and function on the new reconstructed thumb were 80 and 88 in average, respectively, over a total score of 100. These were higher than those of reconstruction of other digits, but lower than those of elective reconstruction. The donor site after harvest of the great toe was mostly unsatisfied in a view of appearance. Immediate toe-to-hand transfer provides many advantages over elective procedure in acute hand injuries such as single stage reconstruction, shortened convalescent period, early return to work and efficient socio-economic factor. Furthermore because there were no significant differences in success rate, frequency of complications or ultimate functional result, immediate toe-to-hand transfer is a safe and reliable procedure in case of limited indications for acute digits loss.

Beau first described transverse depressions of the fingernails after an acute febrile illness in 1846. It was the result of the temporary arrest of nail matrix formation. The transient interference of nail growth rate is usually induced by disability caused by severe systemic disease. Such as Raynaud disease, myocardial infarction, pulmonary embolism, acute renal failure, psoriasis and dysmenorrhea were reported to be the cause of Beau's line. The trauma caused either in a hand or in a forearm was also reported to be the cause of Beau's line. We experienced patients with Beau's line, two cases secondary to fingertip injury and one case due to fracture in radius. They had Beau's lines in all fingers of traumatized hand and nails of opposite hand were normal. During the follow-up, the growth rate of traumatized fingernails were normal and there was no complication.

Background The purpose of this study was to identify the epidemiologic characteristics of hand tendon injuries in children and to compare these with those of adults. Methods This retrospective study was conducted on acute traumatic tendon injuries of the hand treated at our institution from 2005 to 2013, based on medical records and X-ray findings. Age, sex, hand injured, mechanism of injury, tendons and zones injured, number of affected digits, and comorbidities and complications were analyzed. Patients were divided into 2 groups: a pediatric group (${\leq}15years$) and an adult group (>15 years). Results Over the 9-year study period, 533 patients were surgically treated for acute traumatic tendon injuries of the hand. In the pediatric group (n=76), being male, the right hand, the extensor tendon, complete rupture, the middle finger, and glass injury predominated in hand tendon injuries. In the adult group (n=457), results were similar, but injury to the index finger and knife injury were the most common. An accompanying fracture was more common in the adult group and complication rates were non-significantly different. Conclusions This comparative analysis revealed no significant epidemiologic intergroup differences. The belief that pediatric tendon injuries tend to be less severe is misplaced, and careful physical examination and exploration should be conducted in pediatric cases of hand injury.

Purpose: This study surveyed how victims with acute traumatic hand injuries received pre-hospital care and how satisfied they were with that care. Method: A total of 100 adults were interviewed using a questionnaire at one microsurgical clinic in Korea. Results: Only 12 patients (12.0%) were transported by the ambulance and the others by private or company's vehicles. Only 9 patients (9.0 %) were able to get appropriate first response from the EMTs or industrial health providers at the scene of the accidents. The mean time required for transportation from the scene of the accident to the operation room of the microsurgical clinic was $372.65{\pm}719.17$ minutes. Most of the patients were satisfied with the pre-hospital care provided by the EMT or industrial health providers but dissatisfied with that provided by lay persons. Conclusion: This study demonstrates that there is a lack in the first response provided at the scene and the activation of EMS (Emergency Medical System) for acute hand injury. It is necessary to educate the public about the appropriate first response and rapid transportation to the appropriate microsurgical clinic.

As many people keep small dogs as pets, dog bites are common injuries, accounting for approximately 80%-90% of all animal bite injuries. These injuries usually occur on the upper extremities, most commonly on the fingers. Most of these injuries appear as simple lacerations or abrasions of the skin. Common symptoms include inflammatory reactions of the soft tissue, such as pain, swelling, erythema, and cellulitis. However, the complications of small dog bites may include joint or cartilage injuries, including acute osteomyelitis. Once osteomyelitis develops, it is difficult to diagnose since it has a latency period of approximately 2 weeks. Plain radiography, magnetic resonance imaging, and 3-phase bone scans should be performed when acute osteomyelitis is suspected, and broad-spectrum empiric antibiotic treatment should be administered for approximately 8-12 weeks. We report 3 very rare cases of acute osteomyelitis that occurred after a dog bite injury.

Purpose: The evaluation and management of a completely transected tendon of the hand is relatively clear. In most cases, the integrity is assessed by physical examination(eg, broken normal cascade, motion loss) but occasionally, It happens in troubles. because of pain, limited patient cooperation(eg, child, unconscious patient), and other associated injuries(eg, fractures, foreign bodies). Methods: From september 2006 to August 2007, 28 patients were evaluated with real time ultrasonography preoperatively and postoperatively. Twenty eight patients with injured tendon were evaluated using an HDI 5000 Sono CT(Philips Medical Systems, Bothell, WA) machine with a high resolution, 7.5MHz hockey stick linear probe. Dynamic evaluation was performed in real time. Results: Surgery was performed after the ultrasonographic evaluation. Sonographic diagnosis and intraoperative findings were correlated. Ultrasonographic findings show tendon discontinuity, gaps, and fluid collection. Conclusion: We conclude that ultrasonography is helpful in evaluating and managing acute tendon injury. Especially, in cases of completely lacerated tendon, ultrasonography can identify the location of the proximal tendon stump and partial lacerated tendon, ultrasonographic diagnostic tool can decrease misdiagnosis.

The revision of the Korea Organ Transplantation Act (KOTA) in 2018 included hand/arm among the organs that can be transplanted. The first hand transplantation since the revision of KOTA took place in January 2021. A 62-year-old male patient experienced hand amputation on July 13, 2018, by a catapult injury. The patient first visited our institute 3 months after the injury. After serial interviews and an overall evaluation, the patient was registered on the hand transplantation waiting list in January 2020. On January 9, 2021, the patient underwent hand transplantation at the right distal forearm level. The total operation time was 17 hours 15 minutes, and the cold ischemic time was 4 hours 9 minutes. Postoperative immunosuppression was administered based on the protocol used for kidney transplantation. Two acute rejection episodes occurred, on postoperative days 33 and 41. Both rejection episodes were reversible with rescue therapy of a higher tacrolimus trough level, steroid pulse therapy, and topical immunosuppressants. Controlled passive range of motion exercise was started on postoperative day 10. Dynamic splint was applied on postoperative day 18. At 1 year, graft maintenance and functional improvement were satisfactory, and the patient showed a Disabilities of Arm, Shoulder and Hand score of 25.8. We successfully performed the first hand transplantation surgery under the KOTA amendment. It came from the organic and effective cooperation of plastic, orthopaedic, and transplantation departments and we believe it will guarantee the future ongoing success.

PURPOSE: This study investigated the protective role of high-intensity interval training against acute liver injury induced by D-galactosamine (D-Gal)/lipopolysaccharide (LPS). METHODS: A total of 30 male BALB/c mice aged 5-week were randomly assigned to high-intensity, interval training group (EX, n=10) or control group in cage (Non-EX, n=20) for 10 weeks. Peritoneal injection of D-Gal (700 mg/kg body weight) and LPS ($10{\mu}g/kg$ body weight) was applied to induce acute liver injury, and liver tissue was harvested 6 hours after the injection. Hematoxylin and Eosin (H&E) staining was used for liver histology. Real-time PCR was used to quantify expression of pro-inflammatory and anti-inflammatory genes in the liver. RESULTS: The liver histology showed that D-Gal/LPS treatment resulted in hepatic damage and increased number of neutrophils in conjunction with upregulation of hepatic IL-6 and $TNF-{\alpha}$ mRNAs and downregulation of hepatic $PPAR{\alpha}$ and SIRT1 mRNAs. On the other hand, the 10-week interval training resulted in a significant improvement in cardiorespiratory fitness assessed as run time to exhaustion on a treadmill. In addition, the interval training attenuated the D-Gal/LPS-induced liver damage and increased number of neutrophil in conjunction with downregulation of hepatic IL-6 and $TNF-{\alpha}$ mRNAs and upregulation of hepatic $PPAR{\alpha}$ and SIRT1 mRNAs. CONCLUSIONS: This study suggests that high-intensity interval training suppresses the D-Gal and LPS-induced acute liver damage and inflammatory responses.
