Sacroiliac Joint Transfixation Fusion Arthrodesis: A Comprehensive Look at the Double Screw Fixation

SIJ pain

The Sacroiliac Joint (SIJ) plays a crucial role in providing stability between the spine and the pelvis. Sacroiliac joint dysfunction and arthrosis can lead to debilitating pain and impaired quality of life. Fortunately, advancements in medical technology have led to the development of the Sacroiliac Joint Transfixation Fusion Arthrodesis.


Indications for the Procedure:

Sacroiliac Joint Transfixation Fusion Arthrodesis with the double screw fixation system is primarily indicated for individuals suffering from sacroiliac joint arthrosis and dysfunction. Common indications include:

  1. Chronic Sacroiliac Joint Pain: Patients experiencing persistent pain in the sacroiliac joint region despite conservative treatments may benefit from this procedure.
  2. Joint Instability: Cases where the sacroiliac joint exhibits abnormal movement or instability, leading to pain and dysfunction.
  3. Failed Conservative Treatments: Individuals who have not responded to non-surgical interventions such as physical therapy, medications, and injections.


Description of the Procedure:

The surgical procedure involves the use of a double screw fixation system for sacroiliac joint transfixation fusion arthrodesis. A brief overview of the process includes:

  1. Patient Positioning: The patient is typically placed in a prone position under anesthesia, allowing optimal access to the sacroiliac joint.
  2. Screw Fixation: The double screw fixation system is then employed to stabilize and fuse the sacroiliac joint. The screws are strategically placed to provide maximum stability and promote fusion.
  3. Bone Grafting: In some cases, bone grafts may be used to enhance the fusion process. The bone graft material stimulates the growth of new bone, facilitating the fusion of the sacroiliac joint.


Candidates for the Procedure:

Ideal candidates for Sacroiliac Joint Transfixation Fusion Arthrodesis with the double screw fixation system include:

  1. Persistent Symptoms: Individuals with persistent sacroiliac joint pain that significantly affects daily activities.
  2. Failed Conservative Treatments: Patients who have not achieved relief with conservative treatments and are looking for a more permanent solution.
  3. Confirmed Diagnosis: Candidates with a confirmed diagnosis of sacroiliac joint arthrosis or dysfunction through imaging studies and diagnostic tests.


Success Rates and Clinical Evidence:

Numerous studies have explored the effectiveness of Sacroiliac Joint Transfixation Fusion Arthrodesis with double screw fixation systems. Notable articles include:

  1. "Efficacy of Sacroiliac Joint Fusion: A Systematic Review and Meta-Analysis" - This meta-analysis, published in the Journal of Spine Surgery, examined the outcomes of sacroiliac joint fusion procedures, including those using double screw fixation systems.
  2. "Long-term Follow-up of Sacroiliac Joint Arthrodesis with a Novel Dual Screw System" - Published in the Journal of Orthopedic Surgery, this study provides insights into the long-term success rates and patient outcomes following the use of Erodium's double screw fixation system.


Post-Operative Period and Pain Relief:

Patients can expect a gradual improvement in symptoms following the Sacroiliac Joint Transfixation Fusion Arthrodesis. The post-operative period involves:

  1. Recovery Time: Patients may experience a recovery period of several weeks, during which they are advised to limit activities and follow a rehabilitation program.
  2. Pain Relief: While individual experiences may vary, many patients report a significant reduction in pain within the first few weeks to months post-surgery.
  3. Physical Therapy: Rehabilitation exercises and physical therapy are often prescribed to enhance joint function and promote a full recovery.



Sacroiliac Joint Transfixation Fusion Arthrodesis with the double screw fixation system represents a significant advancement in the surgical management of sacroiliac joint arthrosis and dysfunction. As with any medical procedure, thorough patient evaluation, consideration of alternative treatments, and adherence to evidence-based practices are crucial. Continued research and clinical studies will further contribute to our understanding of the long-term success and outcomes associated with this innovative approach to sacroiliac joint treatment.


Apollo Pain Management is proud to offer this state-of-the-art procedure to our patients. Ask your APM physician if the SI Joint Transfixation Fusion is right for you.
