Results of a clinical trial show encouraging results from a minimally invasive implant procedure for the treatment of pain and disability associated with sacroiliac joint dysfunction (SJI) according to SI-BONE, the manufacturer of the SIJ implants. The randomized controlled trial compared outcomes in patients who received minimally invasive SIJ fusion using triangular titanium implants to patients who received nonsurgical treatment. The results are reported in the November issue of Neurosurgery.
The SIJ connects the central (sacrum) and lateral (ilium) bones of the pelvis. SIJ disruption or osteoarthritis is a common pain condition, estimated to cause 15% to 23% of cases of chronic low back pain. In the trial, 48 patients with low back pain caused by confirmed SIJ dysfunction were studied. 2/3 were randomly assigned to receive the surgical procedure, involving placement of triangular titanium implants through a small incision to stabilize and fuse the SIJ. Nonsurgical management was administered to the remaining subjects, including physical therapy, steroid injections and/or radiofrequency ablation of sacral nerve root lateral branches. Based on reduction in pain and absence of complications at 6 months, treatment was rated successful in 81% of subjects assigned to the SIJ implant procedure, compared to 26% with nonsurgical treatment.
