Pudendal Nerve Compression Syndrome

The pudendal nerve primarily innervates the perineum. This nerve can be gradually stretched and damaged by vaginal deliveries (esp. traumatic births), prolapse of pelvic organs and by pelvic floor descent. This leads to unior bilateral pudendal nerve damage. A direct lesion of the pudendal nerve is rare as it lies deep in the pelvis and is well protected by the pelvic ring. It can be injured however, by pelvic ring fractures, penetrating injuries, and deep hematomas due to injections as well as by bullet and stab wounds. Moreover, it can be damaged by overstretching, for example with repositioning or reduction of fractures on the orthopedic table or by long-continuous stretching due to sitting for prolonged periods, for example, on a bicycle [1].
