Lesser sciatic notch
|Bone: Lesser sciatic notch|
|Right hip bone, external surface, showing greater sciatic notch and lesser sciatic notch, separated by the spine of ischium.|
|Latin||incisura ischiadica minor|
|Gray's||subject #57 235|
Below the ischial spine is a smaller notch, the lesser sciatic notch; it is smooth, coated in the recent state with cartilage, the surface of which presents two or three ridges corresponding to the subdivisions of the tendon of the Obturator internus, which winds over it. It is converted into a foramen by the sacrotuberous and sacrospinous ligaments, and transmits the tendon of the Obturator internus, the nerve which supplies that muscle, and the internal pudendal vessels and nerve.
