Triangular titanium implants for sacroiliac joint fusion

Area of Science:

• Orthopedic Surgery
• Spine Surgery
• Pain Management

Background:

• Sacroiliac joint (SIJ) dysfunction is often underdiagnosed.
• Previous studies show positive midterm outcomes for SIJ fusion with titanium implants.
• This study evaluates 12-month outcomes of SIJ fusion in a clinical setting.

Purpose of the Study:

• To assess the 12-month efficacy and safety of SIJ fusion using triangular titanium implants.
• To evaluate improvements in pain and disability for patients with SIJ dysfunction.
• To report on perioperative adverse events and implant integrity.

Main Methods:

• 160 patients with SIJ dysfunction underwent unilateral or bilateral SIJ fusion with titanium implants.
• Patients were followed for 12 months, reporting pain (VAS) and disability (ODI) scores.
• CT scans were performed at 1 year to assess implant status.

Main Results:

• Significant reductions in SIJ pain (8.0 to 2.5) and disability (45.3 to 16.4) were observed by month 12 (p<0.0001).
• Over 95% of patients achieved clinically significant improvements in pain and ODI.
• Mild adverse events decreased with experience; 16% showed implant reabsorption without breakage.

Conclusions:

• SIJ fusion with triangular titanium implants effectively improves pain and disability in clinical practice.
• The procedure demonstrates a high success rate with acceptable safety.
• Long-term implant integrity is supported by 1-year follow-up data.
