Sacrococcygeal symphysis

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.
It is a slightly moveable joint〔Morris (2005), p 59〕 which is frequently, partially or completely, obliterated in old age,〔Palastanga (2006), p 334〕 homologous with the joints between the bodies of the vertebrae.
== Disc ==
The sacrococcygeal disc or interosseus ligament〔Huijbregts (2001), p 13〕 is similar to the intervertebral discs〔 but thinner, thicker in front and behind than at the sides, and with a firmer texture. The articular surfaces are elliptical with longer transversal axes. The surface on the sacrum is convex and that on the coccyx concave.〔 Occasionally the coccyx is freely movable on the sacrum, most notably during pregnancy; in such cases a synovial membrane is present.
