About
The purpose of this retrospective cohort study was to observe and compare the efficacy of anterior cervical long segment fixation, posterior long segment fixation, and combined anterior and posterior fixation for the treatment of cervical vertebral fracture-dislocations in the lower cervical spine in ankylosing spondylitis.
Full description
This was a retrospective cohort study. Patients operated for fracture-dislocation of the lower cervical vertebrae in ankylosing spondylitis in our hospital from 01/2014 to 01/2024 were retrospectively included as study subjects. Prior to the start of the study, an application will be made for approval through the hospital ethical committee, and the Declaration of Helsinki will be observed during the course of the study. The patients were divided into an anterior group (anterior long-segment cervical fixation), a posterior group (posterior long-segment cervical fixation), and a combined group (combined anterior and posterior fixation) according to the surgical access. The operation time, bleeding, complication occurrence, fracture healing and changes in neurological function of the three groups were compared. In this study, Frankel grading before and after surgery was used as the primary observation index, and operation time, intraoperative bleeding, occurrence of complications, and cervical fracture healing were used as the secondary observation index. SPSS 26.0 (IBM, New York, NY, USA) was applied for statistical analysis in this study.
