Abstract

Objective　To study the characteristics of the sacrospinal ligament （SSL） and its adjacent vessels and nerves, and to provide anatomical basis for the sacrospinal ligament fixation (SSLF).　Methods 24 female cadavers were dissected to measure the relevant anatomic parameters.　Results　The length of left was (5.10±0.36) cm, the right was (5.11±0.30) cm. There was no statistical difference between the length of left and the right SSL length. The inmost part of the pudendal canal was the pudendal nerve, The horizontal distance between the right pudendal nerve and the sciatic spine was (1.51±0.35) cm, the left side was (1.61 ±0.31) cm. SSL was thin but tough, the average thickness in all samples was about 0.2 cm. Coccygeus was located in the lateral side of SSL pelvic cavity. The thickness of the coccygeus was much larger than SSL with a wider cover. The inferior gluteal artery travelled dorsally through the SSL and leave of the pelvis, but 7 of them travelled through the sciatic spine. The sciatic nerve kept away from the SSL. There is no vessel and nerve traveling on the pelvic surface of SSL.　Conclusions 1.51 cm away from the right sciatic spine and 1.61cm away from the left sciatic spine may be the best suspension point for SSLF.
