RESUMEN
BACKGROUND: Traditional skin grafts for syndactyly often cause color mismatches and unsightly donor sites, whereas no-skin-graft methods leave noticeable dorsal hand scars. This study presents plantar full-thickness skin graft (FTSG) from the weight-bearing midline area for syndactyly repair, a novel approach not previously reported in the literature. METHODS: The study included three groups of patients with congenital syndactyly of the hand who underwent primary operations with plantar FTSG (n=70), groin FTSG (n=20), and no-skin-graft techniques (n=22). Postoperative outcomes were evaluated by an assessment panel, and guardians' satisfaction scores were measured. Color similarity between the graft and surrounding skin was assessed using a three-dimensional color space. RESULTS: The plantar FTSG group demonstrated a significantly higher likelihood of receiving an 'excellent' rating compared to the groin FTSG group, with an odds ratio of 6.30 (p<0.001). Color difference analysis showed that plantar FTSG more closely matched surrounding skin color than groin FTSG (6.33 vs. 22.57, p<0.001). Guardians reported greater satisfaction with outcomes on the hand in the plantar FTSG group compared to the groin FTSG and no-skin-graft groups (7.16 vs. 5.05 and 4.36, p<0.001). Satisfaction with donor sites was also significantly higher in the plantar FTSG group than in the groin FTSG group (8.23 vs. 6.30, p<0.001). CONCLUSION: Correction of congenital hand syndactyly using midline plantar FTSG from the weight-bearing area can reduce scarring on the hand dorsum, ensure superior color similarity with surrounding skin, and offer inconspicuous donor sites compared to no-skin-graft or groin FTSG techniques.
RESUMEN
In hand and upper extremity replantation surgery, simultaneous free flap reconstruction restores the physiologic circulation to the amputated part, ensuring its survival, and promotes wound healing through anatomic restoration. Especially in digit replantation, an arterialized venous flap serves to reconstruct both vessel and soft tissue defects simultaneously. Delayed free flap reconstruction aims to enhance both functional improvement and cosmetic acceptance in a successfully replanted part using flaps that include functioning muscle, bone, joint, nerve, and soft tissue.

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 0.5â ×â 0.5 cm to a maximum of 2â ×â 3 cm (average, 0.9â ×â 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.
RESUMEN
Keloid formation after syndactyly division is a stressful situation for patients. In our experience, digital enlargement may be involved in keloid formation following syndactyly divisions. Therefore, we aimed to identify predictive factors and reference values for keloid formation. METHODS: In this retrospective study, 11 keloid patients (seven children, four adults) and 11 nonkeloid patients after syndactyly division (control group) with the same sex, age, webspace division site, and operation were enrolled between 2008 and 2020. Using preoperative x-ray images, we compared bony width, length, area, and protruding index relative to the great toe between keloid and control groups. Additionally, reference values for keloid formation were obtained using receiver operating characteristic curves. Statistical analysis was performed using Spearman's correlation test. RESULTS: When compared with the same digit in the normal foot, distal phalanx (P3) bony base width, area, and protruding index on keloid foot were significantly different between keloid group and control group. The reference values for keloid formation after syndactyly release were 1.34 for the P3 area ratio and 1.61 for the P3 triangular area ratio (using the horizontal length of the P3 base and P3 vertical length). The reliability of reference values for the P3 area ratio and P3 triangular area ratio was excellent for all patients. CONCLUSIONS: If digital enlargement in distal phalanx is present when compared with adjacent toe in patients who had undergone primary foot syndactyly divisions, risk of keloid development should be communicated preoperatively, and preventive strategies for keloid development and close observations are required.
RESUMEN
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.

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.

Wide-awake local anesthesia no tourniquet (WALANT) is a promising development for surgeons and patients through improved operation outcomes in hand and wrist surgery. The authors have mostly used WALANT for flexor and extensor tendon repair, tenolysis, and tendon transfer. Its application at W Hospital in korea has bolstered surgeon confidence in tendon repair integrity, gliding ability, and transfer tension via direct observation and patient feedback. The authors do not use WALANT in complicated tenolysis or in secondary surgeries in previous severe injury situations. The procedure has proven similarly unsuitable in incomplete or complete digit replantation.

The purpose of this study is to analyze the clinical results of patients with scaphoid nonunion treated with arthroscopic bone grafting and K (Kirschner)-wires fixation.We retrospectively reviewed the records of 27 patients with scaphoid nonunion who had been treated with arthroscopic bone grafting and K-wires fixation method from November 2008 to February 2014. The average patient age was 35 years. The time from injury to treatment averaged 45 months. The average follow-up period was 18 months. Bone union was assessed using serial plain radiographs. The functional outcome was evaluated by comparing the modified Mayo wrist score with the visual analog scale (VAS) for pain, which were measured at the time of preoperation and at final follow-up.Union was achieved in 26 of the 27 nonunions (96.29%). The average radiologic union time was 10 weeks. The average VAS score decreased from 6.38 (range, 3-10) preoperatively to 1.59 (range, 0-3) at the final follow-up. The average modified Mayo wrist score improved from 60.19 preoperatively to 83.46 at the final follow-up. According to this score, there were 12 excellent, 6 good, and 9 fair results at the final follow-up.Arthroscopic bone grafting and percutaneous K-wires fixation is an effective treatment method for a scaphoid nonunion and has the advantages of allowing thorough assessment, enabling a comprehensive management approach for scaphoid nonunion in a minimally invasive manner, and this method can also be used for the scaphoid nonunion with SNAC stage I.

Marjolin's ulcer is the malignant transformation of chronic nonhealing ulcers that have developed in burn scars or in any other chronic wound. Development of this malignancy tends to be slow and insidious, but it becomes more aggressive when the Marjolin's ulcer breaks free of the scar. We reviewed 24 cases of patients who complained of chronic burn wounds suspected to be Marjolin's ulcers. Histologically, chronic ulcer and pseudoepitheliomatous hyperplasia were 21%, respectively, and malignancy, including squamous cell carcinoma and leiomyosarcoma, were 58%. The mean latency period was 31.6 ± 13.0 years, and the majority of lesions occurred in the extremities. Pseudoepitheliomatous hyperplasia in chronic burn wounds, which is difficult to distinguish from squamous cell carcinoma and considered as a transitional state to becoming a malignant tumor, should be treated as a malignancy. An aggressive excision and reconstruction with free tissue transfer or regional flap transposition should be adopted for adequate ablation and definitive coverage, rather than skin graft and regular surveillance.

We present 12 cases in which palmaris longus tendocutaneous arterialized venous free flaps were used for the reconstruction of the collateral ligament in compound defects of digits. There were nine cases involving the interphalangeal joint of the fingers and three of the interphalangeal joints of the thumb. The venous flaps survived completely in 10 of the 12 cases. In 11 cases, there were excellent functional results for joint stability, pain, total active motion and pinch power. In all 12 cases, a pain-free joint with excellent stability was achieved after surgery. The palmaris longus tendocutaneous arterialized venous free flap is a good option for reconstruction of composite defects of the collateral ligament of the interphalangeal joint. LEVEL OF EVIDENCE: IV.

In this article, we review microsurgical reconstructive techniques available to treat thumb amputation at different levels based on our experience. We reference techniques used by other surgeons and identify the most suitable technique for different clinical situations. Indications and techniques for microsurgical partial or composite transfer of the great or second toe for thumb reconstruction are summarized. Different microsurgical transfer techniques suggest a great freedom of surgical choices. However, the choices are considerably restricted if all functional and cosmetic requirements are to be met. We recommend individualized surgical design and reconstruction because each case of thumb amputation is unique.

BACKGROUND: We present a one-stage procedure for lengthening the fourth brachymetatarsia with autogenous iliac bone and cartilage cap grafting for the anatomical reconstruction of the metatarsophalangeal (MTP) joint METHODS: During the last 8 years, 56 feet in 41 patients with congenital brachymetatarsia of the fourth toe were corrected with a one-stage operation to reposition the articular cartilage cap to the distal part of interpositional iliac bone graft at the metatarsal epiphysis. RESULTS: The length of the harvested iliac bone graft was 22.9 mm on average. The mean fixation period was 58.5 days, and the mean gain in length and percentage increase was 20.9 mm and 39%, respectively. MRI showed a stable MTP joint over viable cartilage cap in 83.3% of the cases. Mean postoperative American Orthopedic Foot and Ankle Society lesser MTP-interphalangeal score was 82.0. Neither neurovascular impairment nor recurrence of brachymetatarsia occurred in the mean follow-up period of 43.6 months. All patients were satisfied with the postoperative cosmetic results. Thirteen patients (23.2%) complained of limited active dorsiflexion of the fourth toe, and extensor adhesion was released by extensor tenolysis in only one patient. In a single case of nonunion at the bone graft site, additional surgery was not necessary. CONCLUSIONS: Anatomical reconstruction of the fourth brachymetatarsia with one-stage interpositional iliac bone and cartilage cap grafting resulted in excellent cosmetic results and a physiologic MTP joint, providing the benefits of one-stage lengthening with a low complication rate. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

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.

Toe-to-hand transfer is the last option for definitive reconstruction of the hand when digits have been lost as a result of traumatic amputations, congenital anomalies, or tumor ablation. Immediate toe-to-hand transfer for the treatment of acute hand injuries is defined as an emergency operation performed when replantation is impossible or failed. The aim of this article is to propose the indications, advantages and disadvantages of immediate toe to hand transfer as well as to compare the overall results with elective cases.

BACKGROUND: Members of the Maasai tribe spend their days either barefoot or wearing traditional shoes made from recycled car tires. Although they walk long distances (up to 60 km) daily, they do not generally experience foot ailments. Here, we compared parameters associated with the feet, ankles, and gait of middle-aged women in Korea and the Maasai tribe. METHODS: Foot length, calf circumference, hindfoot alignment, step length, cadence, and walking velocity were compared among 20 middle-aged Korean and bush-living Maasai women. Static and dynamic Harris mat footprints were taken to determine the distribution of forefoot pressure patterns during walking. We also compared several radiographic parameters with standing foot and ankle radiographs. RESULTS: The mean foot length and width were significantly longer in Maasai women. Interestingly, 38 ft (96 %) in the Maasai group showed a claw deformity of the toe (s). There were no statistically significant differences in gait-related indices and Harris mat findings between the two groups. On radiographic analysis, tibial anterior surface angle, tibial lateral surface angle, talonavicular coverage angle, talo-first metatarsal angle, Meary angle, and naviculo-cuboidal overlap were significantly greater in the Maasai group, whereas hallux valgus angle and the first and second intermetatarsal angle were greater in the Korean group. CONCLUSIONS: Middle-aged women from the Maasai tribe showed a higher prevalence of abducted forefeet, everted hindfeet, and fallen medial longitudinal arches than did Korean women, while Korean women showed a higher prevalence of hallux valgus, a preserved medial longitudinal arch, and toes that are free from claw deformity.
RESUMEN
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.

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.
