Percutaneous sacroiliac joint arthrodesis: a novel technique

Area of Science:

• Orthopedic surgery
• Spinal fusion techniques
• Minimally invasive procedures

Background:

• Intractable sacroiliac joint (SIJ) pain is a significant clinical challenge.
• Existing SIJ arthrodesis techniques often involve extensive surgical exposure and may not integrate fixation with bone grafting.
• There is a need for innovative SIJ fusion methods combining minimal invasiveness, stable fixation, and bone regeneration.

Purpose of the Study:

• To introduce and evaluate a novel percutaneous sacroiliac joint (SIJ) arthrodesis technique.
• The technique utilizes a Hollow Modular Anchorage screw for instrumented fixation.
• This study aims to assess the efficacy and safety of this new approach for treating chronic SIJ pain.

Main Methods:

• A consecutive case series design was employed.
• Nine patients with intractable SIJ pain underwent the new percutaneous SIJ arthrodesis.
• Outcomes were assessed using the Oswestry Disability Index (ODI) and Visual Analog Scale (VAS) for pain, with a minimum 2-year follow-up.

Main Results:

• The mean ODI score significantly decreased from 59 to 45 post-procedure (P
• Mean VAS pain scores substantially reduced from 8.1 to 4.6 (P
• Average patient satisfaction was reported as 6.8 out of 8.

Conclusions:

• The novel percutaneous SIJ arthrodesis technique shows promise as a safe and effective treatment option.
• This minimally invasive approach may provide significant relief for patients suffering from intractable SIJ pain.
• Further research can validate these findings in larger patient cohorts.
