The procedure takes no more than 15 to 20 minutes under CT guidance. It may take longer if X-ray is used. The time taken for full recovery, leg function, bladder function and blood pressure normalisation is approximately 30 minutes to an hour. Some patients require upwards of 2 hours. With preparation time, you should allow 4 hours between entering the radiology practice or hospital and leaving again. You will not be allowed to leave until your legs and bladder function are normal, your blood pressure is normal, and you are able to sit up and walk normally without feeling dizzy.
The prognosis of sacroiliac joint dysfunction varies depending on the cause of the dysfunction. When the problem is caused by pregnancy, the prognosis is excellent, as the condition usually improves after pregnancy during the postpartum period. Conditions affecting the sacroiliac joints such as ankylosing spondylitis and psoriatic arthritis are chronic, but excellent treatments are available. These treatments can minimize the SI joint pain and prevent destruction of the joints. Degenerative arthritis affecting the SI joint is also a chronic condition and cannot be reversed, but treatments are generally very effective in improving symptoms.
