'''Lesser Sciatic Notch'''

[[File:Gray242.png|thumb|right|300px|The lesser sciatic notch of the human hip bone, shown in red.]]

The '''Lesser Sciatic Notch''' is a notable anatomical feature of the [[human skeleton]]. It is a small, curved depression located on the posterior side of the [[Ischium]], one of the three bones that make up the [[Hip bone|hip bone]].

==Anatomy==

The lesser sciatic notch is situated inferior to the [[Ischial spine]] and superior to the [[Ischial tuberosity]]. It is smaller and less pronounced than the [[Greater sciatic notch]], which is located superior to the ischial spine. The lesser sciatic notch is converted into a foramen (opening) by the [[sacrospinous ligament]] and the [[sacrotuberous ligament]], which cross the notch.

==Function==

The lesser sciatic notch allows passage for several important structures in the human body. These include the [[tendon]] of the [[Obturator internus muscle]], the [[Nerve to obturator internus|nerve to the obturator internus]], and the [[Internal pudendal vessels]].

==Clinical Significance==

The size and shape of the lesser sciatic notch can vary among individuals. In some cases, a narrow or irregularly shaped notch can lead to compression of the structures that pass through it, potentially causing pain or other symptoms. This condition is known as [[Pudendal nerve entrapment]].
