To evaluate the location and depth of placement of sacral sutures in a cadaveric sacrocolpopexy model. Following a 1-hour instructional session, trainees performed an open sacrocolpopexy on unembalmed cadavers under guidance by a Female Pelvic Medicine & Reconstructive Surgery board-certified surgeon. At completion of the session, the presacral tissues were dissected and the location and depth of each sacral suture was identified. A total of 19 sutures were placed by 9 trainees into 8 cadavers. The majority of sutures (14/19, 74%) were placed between L5 and S1. Three sutures (16%) were placed at L5 and 2 (11%) were placed at the S1 vertebral body. The mean depth of the anterior longitudinal ligament (ALL) was 1.4 mm. When assessing depth of suture placement, 13 of 19 (68%) were placed into the ALL without penetrating the disc space. Two sutures (11%) were placed in the tissues superficial to the ALL and 4 (22%) were placed deep to the ALL into the periosteum or disc. This study of cadaveric simulation of open sacrocolpopexy finds that location of sacral suture placement is most commonly at the level of the L5-S1 disc space and that placement of sutures into the underlying disc occurs about 1 in 5 times.
