The intergluteal cleft is a surface anatomy landmark of the pelvis and lower limb. It is the deep furrow or groove that lies between the two gluteal regions (commonly known as the buttocks). It extends from sacral level S3 or S4 and ends just inferior to the apex of the sacrum, at the level of the anus.
The superior tip of the intergluteal cleft forms the apex of the sacral triangle, another cutaneous surface anatomy landmark. The cleft also forms the posterior boundary of the perineum. The sacrum, sacral hiatus and the coccyx can all be palpated in the intergluteal cleft. The region is innervated with cutaneous sensation by the medial cluneal nerves (S1-S3 spinal levels).
English: Intergluteal cleft
Latin: Crena intergluteal
