RESUMO
In cases of replantation, accurate closure of all structures, including bone, tendons, arteries, nerves, and veins is essential. Among these, the vein is a weaker structure and is damaged severely in most amputation cases. After fixation of bone, repair of tendons, nerves, and arteries, surgeons often experience difficulty in performing venous anastomoses. We found that in such cases, venous anastomosis is easy to perform using an additional incision after closure of the original wound. In a 33-year-old male patient with amputation of all four fingers at the metacarpophalangeal joint level, venous anastomoses were performed with dorsal veins using additional incisions after completion of the fixation of bones and repair of all other structures and closure of the skin due to surgical site tension.

PURPOSE: We reported results of percutaneous multiple K-wire fixation technique without passing through the joint in patients with a hand fracture. METHODS: We evaluated a total of 116 cases in 94 patients who underwent percutaneous multiple K-wire fixation on dorsal cortex over a 10-year period between 2001 and 2010. The treatment outcomes were evaluated based on total active motion (TAM), as proposed by Widegrow. RESULTS: Our clinical series of patients achieved good functional outcomes. Of total patients, 89% (84/94) had excellent TAM, 2% (2/94) did good TAM and 9% (8/94) did poor TAM. Postoperatively, our clinical series of patients had such a good compliance as to achieve a TAM of >181degrees when performing the early active movement. There were no notable postoperative complications during the follow-up period. CONCLUSION: Our results indicate that percutaneous multiple K-wire fixation technique without passing through the joint from normal bone density patients is effective in providing the rigid fixation. Thus, our patients could perform the early movement as promptly as possible and maintaining the full mobility of the rest of the hand.

PURPOSE: The recent advances in microsurgical techniques and their refinement over the past decade have greatly expanded the indications for digital replantations and have enabled us to salvage severed fingers more often. Many studies have reported greater than 80% viability rates in replantation surgery with functional results. However, replantation of multi-level amputations still remain a challenging problem and the decision of whether or not to replant an amputated part is difficult even for an experienced reconstructive surgeon because the ultimate functional result is unpredictable. METHODS: Between January of 2002 and May of 2008, we treated 10 multi-level amputated digits of 7 patients. After brachial plexus block, meticulous replantation procedure was performed under microscopic magnification. Postoperatively, hand elevation, heat lamp, drug therapy and hyperbaric oxygen therapy were applied with careful observation of digital circulation. Early rehabilitation protocol was performed for functional improvement. RESULTS: Among the 19 amputated segments of 10 digits, 16 segments survived completely without any complications. Overall survival rate was 84%. Complete necrosis of one finger tip segment and partial necrosis of two distal amputated segments developed and subsequent surgical interventions such as groin flap, local advancement flap and skin graft were performed. The overall result was functionally and aesthetically satisfactory. CONCLUSION: We experienced successful replantations of multi-level amputated digits. When we encounter a multi-level amputation, the key question is whether or not it is a contraindication to replantation. Despite the demand for skillful microsurgical technique and longer operative time, the authors' results prove it is worth attempting replantations in multi-level amputation because of the superiority in aesthetic and functional results.
