Sacroiliac joint fusion surgery may be recommended to treat sacroiliac joint pain when nonsurgical treatments are ineffective. In a fusion surgery, a bone graft and/or instruments are used to encourage bone growth over the sacroiliac joint and create one immobile unit. Joint fusion can effectively reduce pain and instability caused by sacroiliac joint dysfunction or inflammation (sacroiliitis).
Most cases of sacroiliac joint pain can be treated using pain medication, injection treatments, chiropractic manipulation, and/or physical therapy, and surgery is usually not necessary.
