Study DesignLiterature review with clinical recommendations.ObjectiveTo highlight important studies related to spinopelvic fixation and provide recommendations to practicing clinicians on interpretation and utilization of the evidence included in these studies.MethodsImportant literature related to spinopelvic fixation was reviewed and clinical recommendations were formulated. Recommendations were graded as strong or conditional.ResultsThree articles were selected and reviewed for the strength of methodology and scientific evidence. Article 1: Biomechanical analysis of lumbosacral fixation in Lumbar Fusion and Stabilization was granted conditional recommendation to consider biomechanical factors associated with different pelvic constructs. Article 2: Low profile pelvic fixation: anatomic parameters for sacral alar-iliac fixation vs traditional iliac fixation was granted strong recommendation to consider risk and benefits in choosing S2AI vs traditional iliac screw for pelvic fixation. Article 3: Rates of loosening, failure, and revision of iliac fixation in adult deformity surgery was granted a conditional recommendation, for taking into account different potential failure mechanisms in S2AI vs traditional iliac screws in pelvic fixation.ConclusionsCurrently evolving strategies have included multiple points of pelvic fixation, multiple rods to the pelvis and strategies with concomitant fusion of the sacro-iliac joints. The high mechanical failure rate at the lumbosacral junction indicates that there is still further opportunity for optimization. It is important to consider the risks and benefits of different pelvic fixation methods to optimize the outcomes for individual patients.
研究设计 带有临床建议的文献综述。 目的 强调与脊柱骨盆固定相关的重要研究,并就这些研究中证据的解读和应用向临床医生提供建议。 方法 对与脊柱骨盆固定相关的重要文献进行综述,并制定临床建议。建议分为强烈推荐和有条件推荐。 结果 选取了三篇文章,根据方法学的优势和科学证据进行综述。文章1:《腰椎融合与稳定术中腰骶部固定的生物力学分析》,有条件推荐考虑与不同骨盆结构相关的生物力学因素。文章2:《低轮廓骨盆固定:骶骨翼-髂骨固定与传统髂骨固定的解剖学参数》,强烈推荐在选择骶骨翼-髂骨固定(S2AI)与传统髂骨螺钉进行骨盆固定时考虑风险和益处。文章3:《成人脊柱畸形手术中髂骨固定的松动、失败和翻修率》,有条件推荐,因为要考虑骶骨翼-髂骨固定与传统髂骨螺钉在骨盆固定中不同的潜在失败机制。 结论 目前不断发展的策略包括骨盆固定的多个点、多条连接骨盆的棒以及骶髂关节同时融合的策略。腰骶部交界处较高的机械故障率表明仍有进一步优化的空间。考虑不同骨盆固定方法的风险和益处对于优化个体患者的治疗效果很重要。
