This black-and-white engraved illustration depicts the posterior view of the human sacrococcygeal junction, highlighting the articulation between the sacrum and the coccyx. Key anatomical features are labeled: IV denotes the fourth sacral vertebra, P marks the posterior sacrococcygeal ligament, G indicates the gluteus maximus attachment near the ischial tuberosity (Is), and Kn refers to the coccygeal ligaments. The fine cross-hatching technique emphasizes bone texture and spatial relationships critical for clinical understanding.

Used in medical textbooks, anatomy courses, and orthopedic or physiotherapy resources to teach pelvic anatomy, coccydynia causes, or surgical approaches to the tailbone region; matches user intent for academic study or clinical reference.
