Objective To summarize the cl inical experience of repairing soft tissue defect in dorsal pedis with reversed fascia pedicled peroneal perforating branch sural neurofasciocutaneous flap, and to explore surgery matters needingattention and measures to prevent flap necrosis. Methods Between August 2000 and April 2009, 31 patients with soft tissue defects in dorsal pedis were treated with reversed fascia pedicled peroneal perforating branch sural neurofasciocutaneous flaps. There were 23 males and 8 females with a median age of 34 years (range, 3-65 years). Defects were caused by traffic accident in 20 cases, by machine in 2 cases, and by crush in 2 cases. The time from injury to admission was 1-32 days (mean, 15 days). And 6 cases had chronic ulcer or unstable scar excision with disease duration of 6 months to 10 years, and 1 case had squamous carcinoma with disease duration of 5 months. The wounds were located in medial dorsal pedis in 12 cases and lateral dorsal pedis in 19 cases; including 14 wounds near the middle metatarsal and 17 wounds beyond the middle metatarsal (up to the metatarsophalangeal joint in 10 cases). All cases accompanied with bone or tendon exposure. Five cases accompanied with long extensor muscle digits tendon rupture and defect, 1 case accompanied with talus fracture, 1 case accompanied with talus fracture and third metatarsal fracture. The size of the wounds ranged from 6.0 cm × 4.5 cm to 17.0 cm × 10.0 cm. The size of the flaps ranged from 8.0 cm × 5.5 cm to 20.0 cm × 12.0 cm. The donor sites were resurfaced by skin graft. Results Seventeen flaps survived uneventfully, wounds healed by first intention. Distal epidermal or superficial necrosis occurred in 6 flaps at 5-12 daysafter operation, wounds healed by dressing change or skin graft. Distal partial necrosis occurred in 8 flaps (7 in medial dorsal pedis and 1 in lateral dorsal pedis) at 7-14 days after operation, wounds healed by skin graft in 3 cases, by secondary suture in 3 cases, by local flap rotation in 1 case, and by cross leg flap in 1 case. All skin grafts at donor sites survived uneventfully, wounds healed by first intention. Twenty-nine patients were followed up 6-29 months (mean, 19 months). The appearance was sl ightly overstaffed, but wearing shoe function and gait were normal. The texture and color of the flaps in all cases were good. There was no pigmentation and suppuration relapse. There was neither ankle plantar flexion deformity nor hammer toe deformity in 5 cases accompanied with long extensor muscle digits tendon rupture and defect. All fractures healed at 3 months after operation in 2 cases. Conclusion The reversed fascia pedicled peroneal perforating branch sural neurofasciocutaneous flaps are suitable to repair most soft tissue defects in lateral dorsal pedis. When the flaps are used to repair soft tissue defects in medial dorsal pedis, avoiding tension in flaps and fascia pedicles should be noted so as to improve flap survival.
Eight patients with macromastia were treated with spoialy designed dermis preserved crossingmammary pedicle flap. A crossed curved scar situated below the edge of the breast was left behind andwas covered by the breast ofter operation. The breast had a good appearlance, mammary mecrosisdidn t occur in any cases. In four patients who had been followed up for six months of longer, thesensation of the nipple and areola had completely recovered in two patients, partially recovered in oneand h...
ObjectiveTo investigate the clinical characteristics of motorcycle spoke heel injury and the effectiveness of sequential therapy of vacuum sealing drainage (VSD) and pedicled flap transplantation for treating motorcycle spoke heel injury in children. MethodsBetween January 2010 and January 2014, 15 children (aged from 3 to 8 years, 5.7 years on average) with motorcycle spoke heel injury received sequential therapy of VSD and pedicled flap transplantation. The interval from injury to admission was 3-7 days, with an average of 4.9 days. The locations were the heel in 8 cases, the heel and lateral malleolus in 2 cases, and the medial malleolus and medial heel in 4 cases, and the medial and lateral malleolus and heel in 1 case. The patients had different degrees of defects of the skin, tendon, and bone. The skin defect size ranged from 3 cm×3 cm to 13 cm×6 cm. VSD was applied for twice in 13 cases and three times in 2 cases. Reversed flow sural flap was applied in 8 cases, lateral supramalleolar flap in 2 cases, medial supramalleolar perforator-based flaps in 4 cases, and posterior tibial artery flap in 1 case. Eight pedicled flaps with neuroanastomosis were selected according to the wound characteristics. The flap size ranged from 4 cm×4 cm to 14 cm×7 cm. ResultsOf 15 cases, 13 flaps survived well except that two had partial skin necrosis at the distal site. Primary healing was obtained, and skin graft at donor site survived. The patients were followed up 9-21 months (mean, 13 months). Mild and moderate bulky flaps were observed in 9 cases and 6 cases respectively. Of 15 cases, 13 could walk with weight loading, and 2 had slight limping. Superficial sensation recovered to S3 in 8 patients undergoing neuroanastomosis, and recovered to S2 in 7 patients not undergoing neuroanastomosis at 6 months after operation. According to AOFAS evaluation system for Ankle-Hindfoot, the results were excellent in 13 cases and good in 2 cases, with an excellent and good rate of 100% at 8 months after operation. ConclusionThe main characteristic of motorcycle spoke heel injury lies in a combination of high energy damage and thermal damage. Sequential therapy of VSD and pedicled flap transplantation can be regarded as a reliable option to obtain good outcome of wound healing and satisfactory functional recovery for the management of motorcycle spoke heel injury.
ObjectiveTo evaluate the effectiveness of different flaps for repair of severe palm scar contracture deformity. MethodsBetween February 2013 and March 2015, thirteen cases of severe palm scar contracture deformity were included in the retrospective review. There were 10 males and 3 females, aged from 14 to 54 years (mean, 39 years). The causes included burn in 9 cases, hot-crush injury in 2 cases, chemical burn in 1 case, and electric burn in 1 case. The disease duration was 6 months to 6 years (mean, 2.3 years). After excising scar, releasing contracture and interrupting adherent muscle and tendon, the soft tissues and skin defects ranged from 6.0 cm×4.5 cm to 17.0 cm×7.5 cm. The radial artery retrograde island flap was used in 2 cases, the pedicled abdominal flaps in 4 cases, the thoracodorsal artery perforator flap in 2 cases, the anterolateral thigh flap in 1 case, and the scapular free flap in 4 cases. The size of flap ranged from 6.0 cm×4.5 cm to 17.0 cm×7.5 cm. ResultsAll flaps survived well. Venous thrombosis of the pedicled abdominal flaps occurred in 1 case, which was cured after dressing change, and healing by first intention was obtained in the others. The mean follow-up time was 8 months (range, 6-14 months). Eight cases underwent operation for 1-3 times to make the flap thinner. At last follow-up, the flaps had good color, and the results of appearance and function were satisfactory. ConclusionSevere palm scar contracture deformity can be effectively repaired by proper application of different flaps.
Objective To summarize the current status of pedicled flaps for defect repair and reconstruction after head and neck tumor resection, and to present its application prospects. Methods Related literature was reviewed, and the role evolution of pedicled flaps in the reconstruction of head and neck defects were discussed. The advance, anatomical basis, indications, advantages, disadvantages, and modification of several frequently used pedicled flaps were summarized. Results The evolution of pedicled flaps application showed a resurgence trend in recent years. Some new pedicled flaps, e.g., submental artery island flap, supraclavicular artery island flap, submandibular gland flap, and facial artery musculomucosal flap, can acquire equivalent or even superior outcome to free flaps in certain cases. Technological modification of some traditional pedicled flaps, e.g., nasolabial flap, pectoralis major myocutaneous flap, latissimus dorsi musculocutaneous flap, temporalis myofascial flap, and temporoparietal fascial flap, can further broaden their indications. These traditional flaps still occupy an irreplaceable role, especially in patients with poor condition and institution with immature microsurgical techniques. Conclusion The pedicled flaps still plays an important role in head and neck reconstruction after tumor resection. In certain cases, they demonstrate some advantages over free flaps, e.g., more convenient harvest, more rapid recovery, less expenditure, and better functional and aesthetic effect.
