Sacroiliac Joint Arthrodesis-MIS Technique with Titanium Implants: Report of the First 50 Patients
Rudolf L*. The Open Orthopaedics Journal. 2012;6:495-502.
This retrospective study of 50 consecutive patients treated by a single orthopedic spine surgeon in private practice was conducted to evaluate the safety and efficacy of minimally invasive sacroiliac joint fusion using a series of triangular, porous plasma spray coated titanium implants.
Medical charts were reviewed for perioperative metrics, complications, pain, quality of life and satisfaction with surgery. All patients were contacted at a 24 months post-op to assess SI joint pain, satisfaction with surgery and work status.
An early and sustained statistically significant improvement in pain function was identified at all post-operative time points (ANOVA, p<0.000). A clinically significant improvement (>2 point change from baseline) was observed in 7 out of 9 domains of daily living. The complication rate was low and more than 80% of patients would have the same surgery again.
MIS SI joint fusion appears to be a safe and effective procedure for the treatment of sacroiliac joint disruption or degenerative sacroiliitis.
