Despite appropriate physiotherapy management, a small percentage of patients with sacroiliac joint dysfunction fail to improve and may require other intervention. This may include pharmaceutical intervention, investigations such as an X-ray, bone scan, CT scan or MRI, blood tests or assessment from a specialist. A corticosteroid injection into the sacroiliac joint may sometimes be used to help alleviate symptoms. In those patients with poor foot biomechanics, review with a podiatrist may be indicated for potential orthotics. The treating physiotherapist can advise on appropriate management and can refer to the appropriate medical authority if it is warranted clinically.
