This report describes an entrapment syndrome of the superficial peroneal nerve terminal sensory branches. Two patients presented with numbness and tingling of the foot dorsum. These symptoms increased with activity such as walking, running, and squatting. The signs were 1) a decrease in sensation to light touch and pin prick on the foot dorsum over the cutaneous distribution of the nerve with sparing of the first web space; 2) a soft tissue bulge over the anterolateral aspect of the leg approximately 10 cm above the lateral malleolus; 3) a Tinel sign over the bulge; 4) an increase in the size of the bulge either with resisted ankle dorsiflexion or weight bearing; and 5) tenderness over the bulge or distally over the terminal sensory branches of the superficial peroneal nerve. Electrodiagnostic studies revealed an unrecordable evoked response or a prolonged distal latency of the terminal sensory branches of the superficial peroneal nerve. Treatment consisted of surgical decompression of the nerve at the bulge by fasciotomy. Patients responded with complete symptomatic relief. To provide accurate treatment, the diagnosis of entrapment syndrome of the superficial peroneal nerve terminal sensory branches must be differentiated from other causes of pain and numbness in the ankle area.
本报告描述了一种腓浅神经终末感觉支卡压综合征。两名患者表现为足背麻木和刺痛。这些症状在行走、跑步和蹲坐等活动时会加重。体征为：1）在神经皮支分布的足背区域，轻触觉和针刺觉减退，第一蹼间隙感觉保留；2）在小腿外侧踝关节上方约10厘米处的前外侧有软组织隆起；3）隆起处有Tinel征；4）抗阻踝背屈或负重时隆起增大；5）隆起处或腓浅神经终末感觉支远端有压痛。电诊断研究显示腓浅神经终末感觉支诱发电位无法记录或远端潜伏期延长。治疗方法为通过筋膜切开术在隆起处对神经进行手术减压。患者症状完全缓解。为了提供准确的治疗，腓浅神经终末感觉支卡压综合征的诊断必须与踝关节区域疼痛和麻木的其他原因相鉴别。
