| Anatomical terms of bone | |
The ischial spine is part of the posterior border of the body of the ischium bone of the pelvis. It is a thin and pointed triangular eminence, more or less elongated in different subjects.
Structure
| Part | Attachment |
|---|---|
| external surface | gemellus superior muscle[1] |
| internal surface | coccygeus muscle,[2] levator ani muscle, pelvic fascia |
| pointed extremity | sacrospinous ligament |
The pudendal nerve travels close to the ischial spine.[3]
Clinical significance
The ischial spine can serve as a landmark in pudendal anesthesia, as the pudendal nerve lies close to the ischial spine.[3][4]
