Apex Of The Coccyx, Lateral View

Description

Coccyx anatomy comes into focus at the coccygeal apex, the rounded distal tip of the terminal vertebral column, presented in lateral profile. Superior to the apex, the coccygeal segments taper toward the base of the coccyx, which articulates with the inferior sacrum at the sacrococcygeal joint. The anterior (pelvic) surface appears concave relative to the posterior surface, reflecting the normal curvature that supports the pelvic outlet. Fine bony contours around the distal coccygeal body and terminal tip are emphasized from this fixed lateral perspective. Small bone, big symptoms. Pain at the coccygeal apex drives a large share of coccydynia cases after a backward fall, childbirth-related strain, or repetitive microtrauma, and a lateral view helps correlate focal tenderness with distal angulation, subluxation at the sacrococcygeal or intercoccygeal joints, and post-fracture callus. Clinicians also reference this region when planning injections aimed at the ganglion impar, where needle trajectory is judged against the anterior contour of the distal coccyx and the adjacent soft-tissue plane. The close, isolated framing makes it easier to teach which surface is anterior versus posterior and to explain why a ventrally curved coccygeal tip can become a contact point during sitting. Use this illustration in gross anatomy and musculoskeletal modules covering the vertebral column, pelvic outlet, and pelvic floor attachments, or in orthopedic, sports medicine, obstetric, and pain medicine materials discussing coccydynia, coccygeal fracture, and coccygectomy landmarks. It also fits radiology teaching files when paired with lateral sacrum and coccyx radiographs for side-by-side interpretation. Anatomical accuracy verified by SciePro's Medical Advisory Board.
