Sacropelvic Fixation Using Iliac Screws: Evaluation of Technique and Complications

Abstract

Sacropelvic fixation arose from the need to protect the sacral instrumentation in long constructions, due to failures in the implant-bone interface and the treatment of diseases in which there is no possibilities of sacral fixation such as infections and tumors. Due to anatomic difficulties and the complex spinopelvic biomechanics several techniques were developed. The fixation with iliac screws has become according to multiple studies, a well-established technique that minimizes frequent complications such as pseudoarthrosis and implant failure. However, it has disadvantages such as iliac wing fracture and skin lesions due to the protrusion of materials. The present study aims to comprehensively review the literature on the technique taking into account relevant aspects to its better knowledge and application. Level of evidence III; Therapeutic Study.
