• 胫神经在腘窝及小腿还发出肌 支支配小腿肌后群
• 胫神经发出腓肠内侧皮神经, 在小腿下部与腓肠外侧皮神经 (发自腓总神经)吻合成腓肠 神经,经外踝后方弓形向前, 分布于足背和小趾外侧缘的皮 肤。

In this repor(, we describe the feasibility of l‹x:ating the sacral plexus nerve using a parasacral approach and an ultrasound-guided technique. The parasacral region using a curved probe (2—SMHz) was scanned in 17 patients iii search of the medial border of the ischial bone and the lateral border of the sacrtim, which represent the limit of the greater sciatic foremen. In addition, attempts were made to identify the pirikirrriis muscles and the gluteal arteries. Tue sacral plexus was identified at the level of tire sciatir fnramen as a round hyperechoic structure. The gluteal arteries were identified in 10 of 17 patients, but we faded to positively identify the pirif-oriiiis
