Sacroiliac joint (SI) pain is an often-overlooked cause of low back pain due, in part, to lack of specific findings on radiographs and symptoms mimicking other back-related disorders. We report our experience with minimally invasive (MIS) SI joint arthrodesis using a series of triangular, titanium plasma spray (TPS) coated implants in patients refractory to conservative care.
We report outcomes from 18 patients with 12 months of postoperative follow-up.Demographics, complications, and clinical outcomes using visual analog scale (VAS) for pain, Oswestry Disability Index (ODI) for back function and SF-12 for quality of life were collected preoperatively and at 3, 6 and 12 months post-operatively.
Mean age was 64 years and 67% of patients were female. There were no intraoperative complications and one explant at three months for malposition.All patient-reported outcomes showed both clinically and statistically significant improvement at 12 months (p < 0.001 for each of the following): VAS improved by 6.6 points, ODI scores improved by -37.5 points. One year SF-12 physical and mental component (PCS, MCS) scores approximated population normal scores for both physical and mental functioning. Patient satisfaction with outcomes was high at 95%; 89% said would have the same surgery again.
MIS SI joint fusion using a series of triangular porous TPS coated titanium implants is a safe and effective procedure for patients with SI joint disorders who have failed conservative care.
骶髂关节（SI）疼痛是下腰痛一个常被忽视的原因，部分原因是X线片缺乏特异性表现以及症状与其他背部相关疾病相似。我们报告了使用一系列三角形钛等离子喷涂（TPS）涂层植入物对保守治疗无效的患者进行微创（MIS）骶髂关节融合术的经验。
我们报告了18例患者术后12个月的随访结果。术前以及术后3个月、6个月和12个月收集患者的人口统计学资料、并发症情况以及使用视觉模拟量表（VAS）评估疼痛、Oswestry功能障碍指数（ODI）评估背部功能和SF-12评估生活质量的临床结果。
平均年龄为64岁，67%的患者为女性。术中无并发症，1例患者在术后3个月因位置不当进行了植入物取出。所有患者报告的结果在12个月时均显示出临床和统计学上的显著改善（以下各项p均<0.001）：VAS改善了6.6分，ODI评分改善了-37.5分。一年时SF-12身体和心理成分（PCS、MCS）评分接近人群身体和心理功能的正常评分。患者对结果的满意度很高，为95%；89%的患者表示愿意再次接受相同的手术。
对于保守治疗失败的骶髂关节疾病患者，使用一系列三角形多孔TPS涂层钛植入物进行MIS骶髂关节融合术是一种安全有效的手术方法。
