Minimally invasive sacroiliac joint (SIJ) fusion has been shown to be safe and effective for the treatment of SIJ dysfunction. Multiple devices are available to perform SIJ fixation or fusion. Surgical revision rates after these procedures have not been directly compared.
We retrospectively identified all patients in our practice who underwent SIJ fixation or fusion between 2003 and 2015. Using both chart review and focused contact with individual patients, we determined the likelihood of surgical revision. Revision rates were compared using Kaplan-Meier survival analysis.
Thirty-eight patients underwent SIJ fixation with screws and 274 patients underwent SIJ fusion using triangular titanium implants. Four-year cumulative revision rates were 30.8% for fixation and 5.7% for fusion.
In our study, SIJ fixation with screws had a much higher revision rate compared to SIJ fusion with triangular titanium implants designed for bone adherence.
微创骶髂关节（SIJ）融合术已被证明在治疗SIJ功能障碍方面是安全有效的。有多种器械可用于进行SIJ固定或融合。这些手术术后的翻修率尚未得到直接比较。
我们回顾性确定了2003年至2015年间在我们诊所接受SIJ固定或融合的所有患者。通过查阅病历和与个体患者进行针对性联系，我们确定了手术翻修的可能性。使用Kaplan-Meier生存分析比较翻修率。
38例患者接受了螺钉固定SIJ，274例患者使用三角形钛植入物进行了SIJ融合。固定的四年累积翻修率为30.8%，融合的为5.7%。
在我们的研究中，与使用为骨附着设计的三角形钛植入物进行SIJ融合相比，螺钉固定SIJ的翻修率要高得多。
