Coccygeal Foveola, Gross Anatomy

Description

Posterior surface anatomy of the lower trunk is rendered in a neutral standing black adult male, centering on the coccygeal foveola (sacrococcygeal dimple) within the intergluteal cleft. The depression lies in the midline over the distal sacrum and coccyx, inferior to the sacral triangle and superior to the coccygeal tip, with the paired gluteal regions forming symmetric lateral contours. Subtle surface landmarks of the sacral and gluteal areas are visible, including the superior gluteal slope overlying gluteus maximus and the narrowing of the cleft as it approaches the coccyx. Small landmark. Clear midline. Clinically, a coccygeal foveola helps orient examinations and procedures around the sacrococcygeal junction, where pain localization can differentiate coccygodynia from sacroiliac referral and soft tissue pathology. The midline dimple also sits in the same corridor where pilonidal disease tends to present, typically cephalad to the coccyx in the natal cleft, and where congenital dermal sinus tracts or atypical pits (high, deep, or with drainage) raise concern for occult spinal dysraphism. Surface relationships matter in coccygeal injections, incision planning for pilonidal excision, and documenting skin findings during newborn and adult physical exams. Use this asset for teaching posterior trunk landmarks in gross anatomy and physical diagnosis courses, for dermatology or colorectal surgery materials discussing the natal cleft and pilonidal sinus, and for patient education on coccyx-region symptoms and skin changes. It also suits atlas-style plates requiring accurate skin tone representation and realistic 3D topography of the sacral and gluteal midline.
