Posterior Sacroiliac Fixation Posterior sacroiliac fixation restores spinopelvic stability in sacroiliac pathology and long spinal constructs. It is technically demanding due to complex pelvic anatomy, variable patient morphology, and the need for precise implant placement to ensure secure fixation while minimizing risks to surrounding neurovascular structures.
The Medacta Spine solution provides a patient-matched platform for precise, reproducible posterior sacroiliac fusion. Dedicated implants and technologies enable accurate positioning and robust fixation tailored to anatomy. By integrating seamlessly into complex spine constructs, the platform is designed to support construct stability, and reproducible outcomes — while respecting established surgical techniques.
