隐神经为股神经四个终末枝中最长的一支,起自腹股沟皱襞,下行至足内侧。在股部与股动脉伴行,至小腿则居浅层与大隐静脉同在一鞘膜内,分布于小腿内侧直至踝部。隐神经为单纯的感觉神经。隐神经痛的原因,按其行程由上到下可分为四类:①在腰部为腰椎间盘(2—3或3—4)病变引起。②在股上2/3段为股神经受刺激(腰大肌炎、股三角区肿瘤、手术创伤等)。③在股下1/3段,内收肌管之内隐神经被包缠。④在小腿,因大隐静脉炎刺激隐神经。前二类已为众所周知,不赘述。后二类尚欠认识,其症状类似下肢血管性疾病,表现为假性间歇性跛行。作者就44例的1～6年观察结果报导如下:
The saphenous nerve is the longest of the four terminal branches of the femoral nerve, starting from the folds of the groin and descending to the medial side of the foot. In the femoral and femoral artery accompanying, to the lower leg is located in the superficial and saphenous vein with a sheath, located in the medial calf until the ankle. The saphenous nerve is a simple sensory nerve. The causes of SID can be divided into four categories according to the itinerary: ① the lumbar disc (2-3 or 3-4) lesions caused. ② In the shares on the 2/3 for the stimulation of the femoral nerve (psoas, femoral triangle tumor, surgical trauma, etc.). ③ In the stock 1/3 of the section, the adductor myotis inner concealed nerve is wrapped. ④ in the lower leg, saphenous vein due to saphenous nerve stimulation. The first two categories are well-known, do not go into details. The latter two are still under-recognized, and their symptoms are similar to lower extremity vascular disease, manifested as pseudo-intermittent claudication. The authors report the results of 1 to 6 years in 44 cases as follows:
