The function of the thumb is critical to overall hand function. The thumb enables motions such as pinch, grip, fine manipulation and allows to circumduction and opposition. It's loss is a serious problem not only from cosmetic point of view but also functional. Therefore, we should make every effort on thumb reconstruction. Many methods of thumb reconstruction from simple osteoplasty to complex microsurgical reconstruction have been reported. We should understand merits and demerits of each method and choose proper method on case by case. When both hands are injured and there is no option but to amputate one hand and the thumb of another hand is lost, spare part flap from the thumb of the amputated hand to another hand can solve cosmetic problem, functional problem and donor morbidity. We report a case of amputated thumb which has been reconstructed with amputated ring finger of the contralateral hand using spare part flap concept.

Purpose : We performed this study in order to analyze the clinical results of functioning gracilis musculocutaneous free flap transplantation for reconstructon of hand function in cases of Volkmann's ischemic contracture and massive soft tissue injury of forearm. Materials and methods : 18 cases were reviewed with 5 yeas of mean follow up period. We evaluated total active motion of the finger joints and wrist, pinch and grip strength. Results : The flap were survived in 17 cases and 1 case was failed due to infection. The sum of active motion of finger joints(TAM) was improved from 0 to $173.8^{\circ}$. The average grip and pinch strength was improved from 0 kg to $2.7{\pm}2.1kg$ and from 0 kg to $2.4{\pm}1.6kg$. Conclusion : The results in most cases were acceptable in relatively long term follow-up. It may be an option for reconstruction of hand function in cases of Volkmann's ischemic contracture and traumatic upper extremity injury.

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.

Recommendable reconstructive surgery in the patient with thumb amputation through base of the first metacarpal bone is pollicization. Some patients who do not agree with harvest sound finger as a new thumb, we can consider other options as toe transplantation or osteoplastic thumb reconstruction for creating thumb. Toe transplantation to the thumb is effective procedure in the amputation of distal to metacarpal shaft, it is rarely indicated in the cases of proximal to base of the first metacarpal bone. We performed three cases of modified osteoplastic thumb reconstruction with free vascularized rib that combined with scapular free flap or radial forearm flap. The length of transplanted rib ranged from 7~11cm, the donor vessels are posterior intercostal artery and vein which anastomosed to radial artery. The grafted rib wrapped with additional free flap for creating new thumb. Result of that procedure was not much encouraging, aesthetic appearance and mobility of thumb were not so satisfactory but reconstructed thumb gave improvement of the hand function without sacrificing toe or other digit. That gave reasonable stability for powerful side pinch and three pod pinch and opposable thumb with normal carpo-metacarpal joint motion that can give much function to the thumb absent hand. In spite of those disadvantages, thumb reconstruction with rib transfer can be useful for patients who do not want to lose another part of the body for creating thumb in basal amputation of the thumb metacarpal.

Purpose: Thumb reconstruction plays most important role in hand injuries because total loss of a thumb constitutes about 40% disability in the hand. The reconstruction can be accomplished by pollicization, free toe-to-thumb transfer, wrap around procedure and lengthening extraction. However, we sometimes need consecutive or double free flaps in the reconstruction of mutilating hand injuries. Methods: We reconstructed a mutilating hand injury in a 54-years old man. Because of severe crushing injury of right thumb and index fingers, we reconstructed a thumb with pollicization using nearly amputated middle finger. Although it survived completely, the adjacent soft tissues which had been covered by fillet flap from the space past was necrosed on 1 month. We debrided the necrotic tissues and covered it with anteromedial thigh perforator free flap consecutively because he had an anatomical variation in branches of lateral femoral circumflex artery. Results: He had an uneventful postoperative course without any complication such as infection, dehiscence and flap necrosis. Three months later, he had undergone tenolysis and defatting procedure of flap site. He recovered the some amount of grip function and was happy with the result. Conclusion: In severe hand trauma including thumb amputation, thumb reconstruction using pollicization and perforator free flap could be an alternative option. It provides minimal donor site morbidity and an acceptable functional result.

An anatomically normal first web space is essential for optimal prehensile movements of the thumb and hand. A 28-year-old woman presented with severe scarring and contractures of the first web space of both hands, following a flame burn injury sustained 25 years prior to presentation. First web space contracture may occur secondary to severe injuries, burns (as observed in our patient), or congenital hand anomalies. A significant amount of additional skin is required to release a severe first web space contracture. Reconstruction of wide areas of contractures using only local flaps is challenging. Among other free flaps used in clinical practice, the thinned lateral arm free flap provides flexible vascularized tissue for reconstruction of the skin after severe first web space contracture release. Reconstruction using lateral arm free flaps facilitated thumb abduction and opposition (which were initially difficult) and improved hand function in our patient.

Because traumatic tissue damage on hands and feet often lead to loss of function, permanent deformity, prompt and adequate reconstruction is essential. For children, future growth, as well as function and esthetics, must be taken into account. Several techniques have been employed to reconstruct hand and foot dorsum defects of children. However, skin graft and muscle free flap with skin graft cannot prevent contracture and will interfere with normal growth. Fasciocutaneous free flap reduces contracture and enables early physical therapy, decreasing the need for additional surgical intervention. Parascapular flap is particularly suitable because it has reliable pedicle and is relatively thin. There is little functional loss in the donor site, and also simultaneous extensor tendon reconstruction of hand and foot is possible. The disadvantage of this technique is that postoperative defatting is needed to adjust volume. Our department has achieved satisfactory results using this approach, and would like to report 13 cases of hand and foot reconstruction using parascapular flap in patients under the age of 15 (from March, 1998 to May, 2003).

Purpose: The hand is frequently affected area in high voltage electrical burn injury as an input or output sites. Electrical burn affecting the hand may produce full thickness necrosis of the skin and damage deep structures beneath the eschar, affecting the tendon, nerve, vessel, even bone which result in serious dysfunction of the hand. As promising methods for the reconstruction of the hand defects in electrical burn patients, we have used the peroneal perforator free flaps. Methods: From March 2005 to June 2006, we applied peroneal perforator free flap to five patients with high tension electrical burn in the hand. Vascular pedicle ranged from 4cm to 5cm and flap size was from $4{\times}2.5cm$ to $7{\times}4cm$. Donor site was closed primarily.Results: All flaps survived completely. There was no need to sacrifice any main artery in the lower leg, and there was minimal morbidity at donor site. During the follow-ups, we got satisfactory results both in hand function and in aesthetic aspects.Conclusion: The peroneal perforator flap is a very thin, pliable flap with minimal donor site morbidity and is suitable for the reconstruction of small and medium sized wound defect, especially hand with electrical burn injury.

Background Primary malignant tumors of the hand, although unusual, may present varied and often complex clinical problems. The main treatment modality of skin cancer of the hand has changed. Methods We retrospectively reviewed the medical records of 43 patients who underwent surgery for malignant skin tumors of the hand during an 18-year period, from September 1994 to February 2012. The characteristics of the tumor, methods of reconstruction, and long-term results were reviewed. Results We had 43 patients with 27 melanomas, 14 squamous cell carcinomas, and 2 sarcomas. Their ages ranged from 19 to 74 years (mean, $53.4{\pm}14.5$ years), from 46 to 79 years (mean, $59.7{\pm}9.6$ years), and from 15 to 43 years (mean, $29{\pm}19.8$ years), respectively. Thirty-four cases occurred on the fingertip (16 of those cases on the thumb), 5 cases occurred on the palm, and 4 cases on the dorsum of the hand. Amputation was most frequently used in early cases, but recently, tissue-sparing excision has been performed frequently. The incidence of local recurrence was 3 cases and distant metastasis was 1 case, and the 5-year survival rate was 100%, except in 4 cases due to follow-up loss. Conclusions The principles of treatment-to be curative and to preserve function and appearance-are important points. "Preservative surgery" preserves function and cosmesis of the involved finger or hand dorsum or palm. Preservative surgery not only emphasizes less resection and surgery of a smaller scale, but also optimal reconstruction of the soft tissue defect of the digit.

Background Digital amputation is a common upper extremity injury and can cause significant impairment in hand function, as well as psychosocial stigma. Currently, the gold standard for the reconstruction of such injuries involves autologous reconstruction. However, when this or other autologous options are not available, prosthetic reconstruction can provide a functionally and aesthetically viable alternative. This study describes a novel technique, known as a tripod titanium mini-plate, for osseointegrated digit prostheses, and reviews the outcomes in a set of consecutive patients. Methods A retrospective review of patients who underwent 2-stage prosthetic reconstruction of digit amputations was performed. Demographic information, occupation, mechanism of injury, number of amputated fingers, and level of amputation were reviewed. Functional and aesthetic outcomes were assessed using the quick disabilities of the arm, shoulder, and hand (Q-DASH) scale and a visual analog scale (VAS) score, respectively. In addition, complications during the postoperative period were recorded. Results Seven patients were included in this study. Their average age was 29 years. Five patients had single-digit amputations and 2 patients had multiple-digit amputations. Functional and aesthetic outcomes were assessed using the Q-DASH score (average, 10.4) and VAS score (average, 9.1), respectively. One episode of mild cellulitis was seen at 24 months of follow-up. However, it was treated successfully with oral antibiotics. No other complications were reported. Conclusions When autologous reconstruction is not suitable for digit reconstruction, prosthetic osseointegrated reconstruction can provide good aesthetic and functional results. However, larger series with longer-term follow-up are required in order to rule out the possibility of other complications.
