ISG (sacroiliac joint) syndrome describes a condition of the lower spine and pelvis. The sacroiliac joint connects the spine to the pelvis. Signs of wear and tear, incorrect stress or accidents can be the cause of ISG syndrome and lead to pain.
Affected persons with ISG syndrome mainly have pain in the sacroiliac joint. Sitting in particular is difficult. Often, one half of the buttocks is raised. ISG pain usually occurs in attacks and when bending or twisting the trunk. Those affected also suffer from the typical complaints when walking, after long periods of physical exertion or when turning in bed.
One possible treatment approach is infiltration therapy, in which the physician injects numbing drugs (local anesthetics) directly into the site of the pain. Either the local anesthetics are injected into the ligamentous apparatus of the sacroiliac joint or directly into the joint space. It is often sufficient to shut down the pain receptors in the ligaments in this way; otherwise, the physician injects the medication directly into the joint under X-ray control.
In addition to local anesthetics, anti-inflammatory and pain-relieving substances, such as cortisone or homeopathic remedies, can also be injected. A new method helps when all other methods fail, endoscopic ISG denervation. Here, a deneration of the ISG is performed via small stab incisions of less than 1 cm.
