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.

Retrospective radiographic review. ⋯ The mandibular angle was shown to be the most consistently palpable landmark. Further, the distance from the mandible, measured on preoperative plain lateral cervical spine radiographs, is an accurate template to determine cervical spine levels during anterior cervical spine surgery.

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.

Practice Guideline
Interventional therapies, surgery, and interdisciplinary rehabilitation for low back pain: an evidence-based clinical practice guideline from the American Pain Society.
Clinical practice guideline. ⋯ Recommendations on use of interventional diagnostic tests and therapies, surgery, and interdisciplinary rehabilitation are presented. Due to important trade-offs between potential benefits, harms, costs, and burdens of alternative therapies, shared decision-making is an important component of a number of the recommendations.

Case report and clinical discussion. ⋯ This report documents a rare case of air passage into multiple body compartments after thoracoscopic-assisted treatment of a spinal fracture, which has not yet been described previously. After exclusion of a tracheo-bronchial and hollow organ injury the process was self-limiting. To avoid this complication, special care should be taken to evacuate all intrathoracal air at the end of the endoscopic procedure.
