The feasibility and radiological features of sacral alar iliac fixation in an adult population: a 3D imaging study.

ABSTRACT:

Background

Surgical treatments for adult spinal deformities often include pelvic fixation, and the feasibility of sacral-2 alar iliac (S2AI) screw fixation has been shown previously. However, sometimes S2AI screw fixation cannot be applied due to the presence of an osteolytic lesion or trauma or because the biomechanical properties of only an S2AI screw is insufficient. Therefore, we questioned the feasibility of using sacral AI screws in other segments and determined whether S3AI and S4AI screws have the potential to be used for sacral fractures. The aim of this study was to investigate the feasibility and radiological features of sacral AI fixation in S1-S4 in an adult population using 3D imaging techniques.

Methods

Computed tomography (CT) scans were taken of 45 patients
