Abstract

Abstract:

Objective　To observe the applied anatomy of the rectosacral fasia (RSF) for axial lumbar interbody fusion(Axial LIF).　Methods　The pelvic region of 10 human specimens were divided into 20 halves in the median sagittal plane. Related anatomical data of the RSF were collected from all specimens.　Results　(1) The RSF mostly originated from the level of the S2 in 44.4% which divided the presacral space into superior and inferior portions. (2) The RSF of men were across both sides of the rectum and connected to the parietal peritoneum of the pelvic, and the RSF of women were connected to the rectouterine fold. (3) The average length of the RSF was (23.14±1.41) mm, the average thickness was (1.25±0.13) mm, the average distance to surgical incision (66.10±7.03) mm, the average distance to the midpoint of S1/S2 cable(23.09±1.87) mm.　Conclusion　(1) The RSF existed universally in the presacral space which should be dissected sharply in surgery to avoid the injury to the presacral venous plexus. (2)The RSF of women may be a part of the uterosacral ligament.

Key words: Axial lumbar interbody fusion, The rectosacral fasia, The presacral venous plexus, Uterosacral ligament
