The sacrococcygeal symphysis (sacrococcygeal articulation, articulation of the sacrum and coccyx) is an amphiarthrodial joint, formed between the oval surface at the apex of the sacrum, and the base of the coccyx.
- Anterior sacrococcygeal ligament
- Posterior sacrococcygeal ligament
- Lateral sacrococcygeal ligament
- Interposed fibrocartilage ligament
- Interarticular ligament
The movements which take place between the sacrum and coccyx, and between the different pieces of the latter bone, are forward and backward; they are very limited. Their extent increases during pregnancy.
