Abstract:

Objective To study anatomy of the gluteal slings and their relationship to adjacent structures,in order to provide the anatomical basis of gluteal sling to avoid its compression on the sciatic nerve. Methods The gluteal sling was examined in 24 sides of 12 adult cadavers. Its relation with the sciatic nerve, first perforating artery, the tip of greater trochanter and the ischial tuberosity were evaluated. Results The mean length of the gluteal sling was measured as（8.68±0.80）cm. The mean distance of the tip of the greater trochanter to the proximal edge of the gluteal sling was（6.57±0.92）cm。The distance between the fibers of the gluteus maximus which passed just inferior to the distal tip of the ischial tuberosity and the proximal edge of the gluteal sling was measured as（5.56±0.71）cm. The angle between the sciatic nerve and the line that intersected the IT and the distal aspect of the proximal 2/3 of the gluteal sling was (42.2±5.4)°。The distance of the sciatic nerve to the proximal edge of the gluteal sling was measured as（2.93±0.56）cm and to the distal edge of the gluteal sling was (2.30±0.42)cm. The mean distance between the tip of the greater trochanter and first perforating artery was (10.84±0.54)cm. The ascending branch of the first perforating artery was closer to the tip of the greater trochanter being (8.77±0.58)cm. The distance of the proximal edge of the gluteal sling to the first perforating artery was (3.84±0.53)cm. The corresponding distance to its ascending branch was closer, being(1.78±0.93) cm. Conclusion Theoretically, it is enough to release about 6cm of the gluteal sling from the proximal to avoid its compression on the sciatic nerve. The first perforating artery，particularly, the ascending branch of the first perforating artery was under risk of injury if it is not dissected carefully from the surrounding structures.
