Sacropelvic fixation: An overview and update on current techniques

The lumbosacral junction presents several unique challenges for spine surgeons. Of the many techniques developed to meet the anatomic and biomechanical challenges the lumbosacral junction presents and to address historically high complication rates, only a handful are commonly used today. Originally described 10 years ago, the S2-alar-iliac technique is the newest of these techniques, and evidence supports its simplicity, efficacy, lower complication rates, and other advantages compared with other methods. This article discusses the general principles underlying sacropelvic fixation and summarizes the recent literature regarding current techniques.
