BACKGROUND: @entity2720 is a prevalent cause of chronic, unremitting @entity615 . OBJECTIVE: To concurrently compare outcomes after surgical and nonsurgical treatment for chronic @entity2720 . METHODS: A total of 148 subjects with @entity2720 were randomly assigned to minimally invasive SIJ fusion with triangular @entity702 implants (n = 102) or nonsurgical management (n = 46). @entity158 , disability, and quality-of-life scores were collected at baseline and at 1, 3, 6, and 12 months. Success rates were compared using Bayesian methods. Crossover from nonsurgical to surgical care was allowed after the 6-month study visit was complete. RESULTS: Six-month success rates were higher in the surgical group (81.4% vs 26.1%; posterior probability of superiority > 0.9999). Clinically important (>=  15 point) @entity717 Index improvement at 6 months occurred in 73.3% of the SIJ fusion group vs 13.6% of the nonsurgical management group (P < .001). At 12 months, improvements in @entity158 and @entity717 Index were sustained in the surgical group. Subjects who crossed over had improvements in @entity158 , disability, and quality of life similar to those in the original surgical group. Adverse events were slightly more common in the surgical group (1.3 vs 1.1 events per subject; P = .31). CONCLUSION: This Level 1 study showed that minimally invasive SIJ fusion using triangular @entity702 implants was more effective than nonsurgical management at 1 year in relieving @entity158 , improving function, and improving quality of life in @entity1 with @entity2720 caused by @entity179 or SIJ disruptions. @entity158 , disability, and quality of life also improved after crossover from nonsurgical to surgical treatment.
