为髋关节直接外侧入路确定臀上神经的体表投影和手术安全区 ,在 44侧的成人尸体标本上 ,解剖观测了与该入路关系紧密的臀上神经最下支分支的分布。结果手术入路的安全区为①在经大转子尖分别作与髂后上棘连线、髂嵴垂直连线、髂前上棘上方 3cm和髂前上棘连线 ,在这些连线上 ,最下支距大转子尖的距离分别为 5 5± 0 6、 4 8± 0 6、 4 3± 0 6、 6 4± 0 8cm ;②在经大转子外侧最凸点分别作与髂后上棘连线、髂嵴垂直连线、髂前上棘上方 6cm和 3cm的髂嵴连线 ,最下支距大转子外侧最凸点的距离分别为 1 0 0± 0 8、 9 0± 0 8、 7 5± 0 6、 8 9± 0 7cm。上述两组数值所在点作连线即分别为最下支神经的体表投影。结果表明 :投影以下至大转子尖或大转子外侧最凸点之间无明显血管神经分布 ,在此区内撑开臀中、小肌肌纤维显露髋臼均不会损伤臀上神经
In order to determine the projection of the superior gluteal nerve and the operative safe zone for the direct lateral hip approach, the distribution of the inferior branch of the superior gluteal nerve, which is closely related to this approach, was dissected and observed on 44 adult cadaver specimens. Results Surgical approach to the safe area for the greater trochanter were connected with the posterior superior iliac spine, iliac crest vertical connection, 3cm above the anterior superior iliac spine and the anterior superior iliac spine in the connection, in these connections, The distance from the greater trochanter to the lowermost trochanter was respectively 55 ± 0 6, 48 ± 0 6, 43 ± 0 6, 64 ± 0 8cm; Spine connection, the iliac crest vertical connection, the iliac crest 6 cm and 3 cm above the anterior superior iliac spine, the most distance from the most bulge point outside the greater trochanter were 100 ± 0 8, 90 ± 0 8 , 7 5 ± 0 6, 8 9 ± 0 7cm. The point where the above two numbers are connected is the body surface projection of the lowest branch of the nerve, respectively. The results show that there is no obvious vascular nerve distribution between the projection below the bulge of the greater trochanter and the bulge of the greater trochanter. In this region, the gluteal nerve
