Multicenter Study
Functional and radiological outcomes of 360 degrees fusion of three or more motion levels in the lumbar spine for degenerative disc disease.
This is a single-center, multisurgeon, retrospective study of radiologic and functional outcome measures at a minimum 2-year follow-up. ⋯ The surgical treatment of lumbar degenerative disc disease by 360 degrees fusion should be considered for properly selected patients. The goal of surgery is reduction, not elimination of disability.

Comparative Study
Patient-preference disability assessment for disabling chronic low back pain: a cross-sectional survey.
A cross sectional survey. OBJECTIVE.: To assess patient priorities in disability and restriction in participation with disabling chronic low back pain (CLBP) by use of the McMaster-Toronto Arthritis Patient Preference Disability Questionnaire (MACTAR) and to compare this questionnaire with other outcome measures widely used in this situation. ⋯ For assessing priorities in disability and participation restriction among patients with CLBP, the MACTAR has acceptable construct validity. The weak correlation between QUEBEC and MACTAR scores suggests that the latter scale adds useful information for assessing the health priorities of disabled CLBP patients.

Randomized Controlled Trial
Effect of modified techniques in Bryan cervical disc arthroplasty.
A prospective, randomized study of the clinical and radiographic outcomes in patients undergoing single- and 2-level cervical arthroplasty with Bryan cervical disc (Medtronic Sofamor Danek, Memphis, TN). ⋯ The modified techniques can improve the outcomes of the cervical arthroplasty with Bryan disc and prevent the unexpected imbalance and motion of cervical spine.
