目的 评价不同皮瓣、肌皮瓣修复小腿及足踝部皮肤软组织缺损的效果，探讨小腿及足踝部皮肤软组织缺损的理想修复方法。 方法 2002年6月－2010年1月，应用15种皮瓣、肌皮瓣修复128例（138处）小腿及足踝部皮肤软组织缺损。其中小腿中上段21处，小腿中下段45处，内外踝及足跟部43处，足背及前足29处。主要应用最多的皮瓣有腓肠神经营养血管皮瓣、腓肠肌内外侧头肌皮瓣、腓浅神经营养血管皮瓣和足底内侧皮瓣。修复软组织缺损范围5 cm×4 cm～23 cm×14 cm。 结果 术后135处创面Ⅰ期愈合，皮瓣完全成活；2处皮瓣部分坏死，经二次手术植皮修复；1例游离股前外侧皮瓣修复小腿中下段软组织缺损，皮瓣完全坏死，后改取对侧腓肠神经营养血管交腿皮瓣修复成活。腓肠神经营养血管皮瓣应用例数最多，成活率高，吻合血管的游离皮瓣坏死率较高。术后患者均获随访1～10年，平均23个月，皮瓣均成活良好, 无溃疡、渗液等。 结论 正确认识并选择皮瓣、肌皮瓣修复小腿及足踝部皮肤软组织缺损可提高皮瓣成活率，恢复肢体良好功能，腓肠神经营养血管皮瓣是一种修复小腿及足踝部软组织缺损的理想皮瓣。
Objective To report the methods and clinical effect of the lateral crural flaps in repairing anterior tibal, dorsal and calcaneal softtissue defects. Methods From August 1999 to December 2004, 18cases of defects were repaired with lateral crural flap, including 15 cases of anterior tibal, dorsal and calcaneal softtissue defects with vascular pedicled island lateral crural flaps and 3 cases of dorsal pedal soft-tissue defects with free vascular lateral crural flaps.〖WTHZ〗Results All flaps survived after operation.Insufficient arterial supply of the flap occurred in 2 cases after operation, the pedicled incision sewing thread was removed and lidocain was injected around vascular pedicle, then the flap ischemia was released. Inadequate venous return and venous hyperemia occurred in 1 case because peroneal vein was injured duringoperation.The flap edge skin was cut and heparin was locally dripped for one week, the flap vascular cycle was resumed. All patients were followed up two months to one year, the flaps were not fat, and the elasticity was good. Conclusion It is safe and reliable to use lateral crural flap to repair anterior tibial, dorsal pedal and calcaneal soft-tissue defects.
ObjectiveTo investigate the effectiveness of wide fascial and doubly vascularized pedicle posterior cnemis flap in repair of the soft tissue defect of forefoot.MethodsBetween March 2011 and March 2017, 18 cases with severe soft tissue defects of forefeet were repaired with the wide fascial and doubly vascularized pedicle posterior cnemis flaps. There were 13 males and 5 females with an average age of 33 years (range, 11-49 years). Of 18 cases, the defects were caused by trauma in 16 cases with an average disease duration of 15 hours (range, 3-72 hours), by infection after correction of spastic clubfoot in 1 case, and by infection after open fracture fixation in 1 case. The defects were on the planta of forefoot in 11 cases and on the dorsum of forefoot in 7 cases. The size of soft tissue defects ranged from 6 cm×4 cm to 15 cm×9 cm. All defects combined with the bone, joint, and tendon exposures and 4 defects combined with fractures. The size of flaps ranged from 8 cm×5 cm to 17 cm×10 cm. All wounds of donor sites were repaired by skin grafting.ResultsThe operation time was 100-190 minutes (mean, 140 minutes). Seventeen flaps survived and wounds healed by first intention. One flap had partial necrosis and cured after dressing change. Seventeen cases were followed up 5-24 months (mean, 16 months). Both the color and texture of the flaps were satisfactory. But the pedicles of flaps were swollen. The functions of foot and ankle returned to normal.ConclusionThe wide fascial and doubly vascularized pedicle posterior cnemis flap has reliable blood supply and sufficient venous reflux to ensure its survive, which can be used to repair severe soft tissue defect of forefoot.
