摘要

Ankylosing spondylitis is a genetic condition [1] that frequently results in spinal sagittal plane deformity of thoracolumbar or cervicothoracic junction. Generally, a combination of osteotomy and spinal fixation is used to treat severe cases of ankylosing spondylitis to restore spinal balance and horizontal gaze [2]. This study investigates the biomechanics of opening wedge osteotomy at the cervicothoracic junction. Although surgical techniques for traumatic injury across the cervicothoracic junction have been well characterized in the clinical and biomechanical literature, the specific model of instrumented opening wedge ostetomy in autofused ankylosing spondylitis has not been studied biomechanically. The goal of this study is to characterize the structural stability of various posterior fusion techniques across the cervicothoracic junction in spines with ankylosing spondylitis by comparing the multi-directional bending rigidity of different cervicothoracic fusion constructs as a function of 1) rod diameter and 2) rod material.
