Multicenter Study Clinical Trial
Relationship between preoperative expectations, satisfaction, and functional outcomes in patients undergoing lumbar and cervical spine surgery: a multicenter study.
Analysis of prospectively collected multicenter data. ⋯ This study showed that more than functional outcomes matter; preoperative expectations and fulfillment of expectations influence postoperative satisfaction in patients undergoing lumbar and cervical spine surgery. This underlines the importance of taking preoperative expectations into account to obtain an informed choice on the basis of the patient's preferences.

Intensity of pain and level of disability (Oswestry Disability Index [ODI]) were compared with the relative size of Modic type 1 (M1) and Modic type 2 (M2) lesions. Clinical symptoms of patients having mixed M1-M2 lesion (n = 49) were compared with patients having a "pure" M1 lesion (n = 13). ⋯ We conclude that the size of M1 lesion does not directly correlate with the clinical symptoms but that the type of Modic lesion is more important. This study supports the previous observations that when the inflammatory process turns to the mixed M1-M2 lesions, clinical symptoms decrease.

Reliability study of the computer-assisted SDSG (Spinal Deformity Study Group) classification of lumbosacral spondylolisthesis. ⋯ Substantial intra- and interobserver reliability was found for the computer-assisted SDSG classification, and all 6 types of lumbosacral spondylolisthesis were identified. Refinement of the computer-assisted classification technique is, however, needed to further increase the reliability of the SDSG classification and facilitate its clinical use.

Randomized Controlled Trial Multicenter Study Comparative Study
Who should have surgery for an intervertebral disc herniation? Comparative effectiveness evidence from the spine patient outcomes research trial.
Combined prospective randomized controlled trial and observational cohort study of intervertebral disc herniation (IDH), an as-treated analysis. ⋯ IDH patients who met strict inclusion criteria improved more with surgery than with nonoperative treatment, regardless of specific characteristics. However, being married, without joint problems, and worsening symptom trend at baseline were associated with a greater TE.

Multicenter Study
Impact of direct vertebral body derotation on rib prominence: are preoperative factors predictive of changes in rib prominence?
Multicenter retrospective review of prospectively collected data. ⋯ Utilizing DVBD, the surgeon can expect approximately 50% reduction in the rib deformity as assessed by inclinometer. This is irrespective of preoperative inclinometer measures, thoracic curve flexibility, and vertebral body rotation on standing and bending radiographs.
