Surgery for DCM leads to significant functional improvement. However, better outcome was observed in younger individuals with lower CCI and absence of radiographic myelopathy signs. Therefore, DCM surgery, particularly before occurrence of high SI on MRI, seems to be essential for postoperative functional improvement regardless the above-mentioned confounders.Level of Evidence 3. Retrospective study. A retrospective study was conducted to clarify the prognostic factors of postoperative for cervical spine fractures patients with ankylosing spondylitis (AS). Now the high probability of cervical fractures in patients with AS is unanimously recognized. Fractures mostly occur in the lower cervical spine and two-thirds of patients are accompanied by spinal cord injury. But there are few studies on treatment of AS patients with cervical fracture and it is unclear whether the surgical method, timing of surgery, basic treatment of AS, and different doses of steroids therapy have an impact on the prognosis. Thus, this study aims to evaluate the impact of perioperative factors on the prognosis of traumatic cervical fractures in surgical patients with AS. Preoperative and postoperative spinal cord function were assessed according to the Japanese Orthopaedic Association (JOA) Scores and Improvement rate were calculated. The neck pain severity were rated using a visual analogue scale (VAS) reoperative steroid application as soon as possible. 3. 3. Retrospective cohort study. The purpose of this study was to utilize the National Readmission Database to determine the national estimates of complication and 90-day readmission rates associated with cervical spinal fusion in adult patients with rheumatoid arthritis (RA). RA patients who undergo cervical spine surgery are known to be
