Sacroiliac joint failure is the disease most commonly misdiagnosed as a lumbar disc herniation. Joint failure means that the joint between the sacrum and the pelvis bone is moving more than necessary. The majority of patients who have not benefited from surgery done without necessary investigations unfortunately have this disease; since the surgeon can diagnose this disease only with a detailed examination. If the operation decision is made before a thorough examination, it is inevitable that the aforementioned sacroiliac joint failure has been missed.
Unfortunately, there is no general test that the surgeon can do to confirm this diagnosis; it is necessary to inject a painkiller into the joint, which is a special sacroiliac block. If this test is positive, the surgery to be performed is sacroiliac joint fusion; that is, immobilizing the joint using special instruments. Nowadays, this procedure can be done by experienced neurosurgeons in the form of a bloodless operation.
