Open versus minimally invasive fixation of thoracic and lumbar spine fractures in patients with ankylosing spinal diseases.

Purpose: Posterior multilevel fixation of traumatic instability in ankylosing spinal disease (ASD) can be performed by open surgery (OS) or minimally invasive surgery (MIS). We investigated whether both methods differ based on the reduction results and perioperative parameters.

Methods: In this retrospective cohort study, OS and MIS groups were investigated.
