The sacro-iliac joint is a joint at the back of the pelvis between the two pelvic bones. Excessive movement in this joint can stress the ligaments and soft tissues that support the joint. Traumatic incidents in sport, falls, hormonal changes in pregnancy and inflammatory joint diseases can cause pain in this area.

Sacro-iliac joint dysfunction usually gives rise to pain on one side of the low back, butttock, groin and thigh pain.

Osteopathy is very effective in the treatment of sacro-iliac joint pain. Treatment may involve activity modification, soft tissue treatment such as massage and stretching, joint mobilisation of surrounding joints that may be stiff and progression to strengthening exercises to improve the stability of the joint.
