Spina ischiadica

spina ischiadica --> ischial spine

A pointed process from the posterior border of the ischium on a level with the lower border of the acetabulum; gives attachment to the sacrospinous ligament; the pudendal nerve passes dorsal to the ischial spine, which is palpable per vagina or rectum, and thus is used as a target for the needle-tip in administering a pudendal nerve block.

Synonym: spina ischiadica, ischiadic spine, sciatic spine.
