Abstract：
Dysfunction of the common peroneal nerve is the most common mononeuropathy in the lower limb and a source of significant disability for patients. The nerve can be damaged at various levels for various reasons (direct or indirect trauma, extrinsic compression, anatomical variant, endocrine, rheumatological, or neurological disease). Clinical evidence of foot drop with steppage gait is very typical. Conservative treatment should be considered as a first step (avoidance of the contributing factors, functional rehabilitation, foot drop brace ± injection). If properly conducted conservative treatment is not successful, palliative surgery is indicated: either tendon transfer using the posterior tibial tendon or ankle arthrodesis.
摘要：
腓总神经的功能障碍是下肢最常见的单神经病，也是患者严重残疾的原因。由于各种原因（直接或间接创伤，外在压缩，解剖变异，内分泌，风湿病,或神经系统疾病）。脚踏步态的临床证据非常典型。保守治疗应被视为第一步（避免影响因素，功能康复,脚下垂支架±注射)。如果正确进行保守治疗不成功，姑息性手术适用于：使用胫骨后肌腱进行肌腱转移或踝关节固定术。
