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.

Analysis of patient and surgeon preference between selective and nonselective thoracic spinal fusions. ⋯ The DFQ quantifies the perceived trade off between residual deformity and spared motion segments. Two-year postoperative patient satisfaction, as measured by the Scoliosis Research Society-24 questionnaire, and surgeon preference, in terms of coronal radiographic outcome, correlated significantly with the DFQ.

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.

Comparative Study
Insertion of the artificial disc replacement: a cadaver study comparing the conventional surgical technique and the use of a navigation system.
Comparison of total disc replacement (TDR) with and without computer-assisted surgical navigation. ⋯ Surgical computer-assisted navigation may be a useful tool in the hands of a spine surgeon to achieve more accurate placement of the disc prosthesis. Because of the parallax effect, computer-assisted navigation offers more placement accuracy than stan- dard fluoroscopy. Because the accurate placement of total disc prosthesis has been correlated with better clinical outcome, further study regarding the navigation of the TDR is essential.

Polish adaptation of the original version of Scoliosis Research Society (SRS) instrument. ⋯ The Polish version of SRS-22 is characterized by high internal consistency for all domains and for the overall score, which makes it an evaluation tool after surgical treatment compatible with the original SRS-22.
