Saphenous nerve, a pure sensory nerve, may compromise as a result or complication of a surgical procedure or secondary to trauma or insidiously. We present a male patient with low back pain concomitant with pain in medial portion of left thigh in addition to pain and numbness in medial part of leg and inferior part of patella after a strenuous activity. Preliminary diagnosis suggested that the patient had radiculopathy but electrodiagnostic tests revealed the absence of left saphenous response both in medial leg and infrapatellar region, while normal findings were recorded from right side. Needle electromyography in L4 innervated muscles were normal. The patient had saphenous nerve entrapment in left thigh. Two months later symptoms relieved with conservative therapy.
隐神经是一种纯感觉神经，可能因外科手术的结果或并发症、外伤继发或不知不觉地受到损害。我们报告一名男性患者，在剧烈活动后出现下背部疼痛，同时左大腿内侧疼痛，以及小腿内侧和髌骨下部疼痛和麻木。初步诊断提示该患者患有神经根病，但电诊断测试显示，在小腿内侧和髌下区域均未引出左侧隐神经反应，而右侧记录结果正常。L4支配肌肉的针极肌电图检查结果正常。该患者存在左侧大腿隐神经卡压。两个月后，经保守治疗症状缓解。
