Lower rotating point nutrient vessels of sural nerve flap with distant pedicled repairing soft tissue defect of foot and ankle

Objective To explore lower rotating potint nutrient vessels of sural nerve flap with distant pedicled repairing the soft tissue defect of foot and ankle. Methods Lay a foundation of anatomic studying from february 2003 to March 2004, using lower rotating point nutrient vessels of sural nerve flap with distant pedicled repairing the soft tissue defect of foot and ankle in 11 cases. Cause of injuring: traffic accident 7 cases, crushing 1 case, saw injuring 1 case, skin cancer 1 case, chronic ulcer 1 case. Areas; foot heel 6 cases, shand lower section 2 cases, heel tendon 2 cases, the distant back of the foot 1 case. Using the flap axis point was 1cm-3cm above the pink of the external heel,average 2cm. The scope of the flap was 6.0cm×8.0cm-12.0cm×18.0cm. Results All sural nerve flap were lively. About all,2 cases have distant part necrosis, accompanying with subcutaneous tissue 1 case heels after change dressings, another heels after skin grating. All case can walk as usal, the flap has wear-resisting and keenly feel. Conclusion Lower rotating point nutrient vessels of sural nerve flap, donner area exiting fine, utlizing scope large, skin nice, grating easy, no hurting important blood vessle,alive rate high,it is an good donner area in repairing around heel, foot and shand lower section.
