Learning about Sacroiliac (SI) Joint Fusion
Sacroiliac (SI) joint fusion is a surgical procedure aimed at relieving pain caused by dysfunction or degeneration of the sacroiliac joint, which connects the base of the spine to the pelvis. This joint can become a source of pain due to conditions like arthritis, trauma, or other degenerative disorders.
Here's an overview of how a sacroiliac joint fusion is typically performed:
1. Preoperative Preparation: Before the surgery, patients undergo imaging studies, such as X-rays or MRI scans, to assess the condition of the SI joint and plan the procedure. Patients are usually given anesthesia, which can be either general (making them unconscious) or spinal (numbing the lower half of the body), depending on the approach and patient needs.
2. Positioning and Incision: The patient is positioned face-down on the operating table. A small incision is made over the SI joint, which is located in the lower back where the sacrum meets the iliac bone of the pelvis. The exact location of the incision may vary based on the surgical technique and the surgeon’s preference.
3. Accessing the SI Joint: Through the incision, the surgeon carefully places a series of small dilators to expose the joint surface.
4. Placing the Fusion Device: The surgeon prepares the joint surfaces by cleaning and smoothing them to promote effective fusion. Then, a bone graft or a synthetic fusion device, such as screws or a plate, is placed across the joint to stabilize it. The choice of device depends on the specific needs of the patient and the surgeon’s recommendation.
5. Fusion and Stabilization: The goal of the fusion device is to hold the joint in a stable position to encourage bone growth and fusion. Over time, the joint surfaces will fuse together with new bone growth, effectively eliminating movement and reducing pain.
6. Closure: After placing the fusion device, the surgeon closes the incision with sutures or staples. Sterile dressings are applied to the wound, and the patient is monitored as they wake up from anesthesia.
7. Recovery and Rehabilitation: The procedure is typically performed on an outpatient basis, meaning the patient will go home after surgery. Recovery involves pain management, physical therapy, and gradual resumption of activities. The fusion process can take several months, during which the patient will follow specific guidelines to ensure proper healing and avoid complications.
SI joint fusion aims to provide long-term relief from pain and improve function for patients with SI joint dysfunction. Call us at 281-868-PAIN (7246) or email info@advspine.org to schedule your consultation with Dr. Khoury today.
