Cadaveric Insights into Pudendal Nerve Variations for Sacrospinous Ligament Fixation: A Case Series.

We identified significant variations in the number of trunks and branching patterns of the pudendal nerve around the SSL and the course of the IRN caudal to the SSL. We documented IRNs or nerves joining the IRNs piercing the SSL. Identifying these variations is crucial for surgeons to minimize the risk of pudendal nerve injury during SSLF.
