Objective: to discuss the relationship between the slide distance of the dorsal digital aponeurosis and the flexion of the PIP and provide anatomic basis for clinical repair.
目的：探讨指背腱膜滑动距离与近侧指间关节(PIP)屈曲关系，为临床修复提供解剖学基础。
Normal gait was restored in all cases. Flexion deformity of toes disappeared in neutral position of ankle joint, and mild flexion deformity of toes existed in dorsal expansion position of ankle joint.
术后患者中立位足趾屈曲畸形消失，步态均恢复正常，踝关节背伸时足趾轻度屈曲畸形。
Conclusions: the decrease of the slide distance of the dorsal digital aponeurosis will influence flexion function of fingers.
结论：指背腱膜滑动距离减少，严重影响手指的屈曲功能。
Follow-up 8 to 24 months, no significant flap bloated appearance, good texture, good ankle flexion and extension, walking normal, and only the lateral dorsal sense of numbness.
随访8 ~24个月，皮瓣外观无明显臃肿，质地良好，踝关节屈伸运动良好，行走正常，仅感足背外侧麻木。
