Sacroiliac (SI) joint fusion

Sacroiliac joint fusion is a surgical procedure designed to stabilize the sacroiliac joint, which is located at the junction of the sacrum (the triangular bone at the base of the spine) and the iliac bones of the pelvis. This joint plays a crucial role in transferring weight between the upper body and lower limbs while allowing for minimal movement necessary for walking and bending. However, when the SI joint becomes unstable or undergoes degeneration due to factors such as arthritis, trauma, or injury, it can lead to chronic pain and discomfort. Sacroiliac joint fusion aims to address this pain and restore stability to the affected joint.

The procedure involves fusing the two bones of the sacroiliac joint together, which effectively eliminates motion at the joint. We typically use implants such as screws, plates, or rods, or by incorporating bone grafts to encourage natural bone growth between the sacrum and iliac bones. These implants and grafts promote healing and eventually result in a solid fusion, providing long-term stability to the joint. The goal is to reduce the abnormal motion that causes pain and to improve function. This allows the patient to resume normal activities with less discomfort.

We often use Sacroiliac joint fusion when more conservative treatments, such as physical therapy, medications, or injections fail to provide adequate relief. We may recommend this for patients suffering from chronic sacroiliac joint pain due to instability, arthritis, or degeneration. Symptoms such as leg, buttocks, or low back pain may be relieved as the fusion addresses the underlying cause.

We can perform the procedure using various techniques. A minimally invasive approach is often available and uses smaller incisions and typically offer a quicker recovery time.
