Where is sacrococcygeal junction located?
tailbone
The sacrococcygeal joint is an articulation between the apex of the sacrum and the base of the coccyx (tailbone). This joint is a symphysis, having the two bones lined by hyaline cartilage and connected by an interposed fibrous disc….Sacrococcygeal joint.

What causes sacrococcygeal pain?
The most common cause of coccydynia is trauma, specifically single direct axial trauma such as a fall, or cumulative trauma, which could result from sitting in a suboptimal position on a hard or uncomfortable surface for a prolonged period.
What is the Sacrococcygeal ligament?
The posterior sacrococcygeal ligament or dorsal sacrococcygeal ligament is a ligament which stretches from the sacrum to the coccyx and thus dorsally across the sacrococcygeal symphysis shared by these two bones.
Where is the Sacrococcygeal membrane?
The sacrococcygeal membrane is a tough fibrous membrane about 10mm long which extends from the inferior tip of the sacrum to the body of the coccyx in humans. It covers the inferior limit of the epidural space and is analogous to the ligamentum flavum found at other levels in the spine.
Why does my Coxis hurt when I sit down?
Tailbone pain — pain that occurs in or around the bony structure at the bottom of the spine (coccyx) — can be caused by trauma to the coccyx during a fall, prolonged sitting on a hard or narrow surface, degenerative joint changes, or vaginal childbirth.
What is between sacrum and coccyx?
The sacrococcygeal joint is the joint in the tailbone formed between the sacrum and the coccyx. The coccyx is a small triangular shaped bone made up of 3-5 fused segments. Many ligaments attach to the coccyx helping to provide stability and support for the pelvis, its muscles and contents.
What is sacrococcygeal pain?
Sacrococcygeal pain can arise from the sacrococcygeal joint, from contiguous structures sharing the same innervation, or from distant sites. True coccygodynia consists of pain arising from the sacrococcygeal joint, whereas pseudococcygodynia consists of pain referred to but not arising from the coccyx.
