A retrospective clinical and radiological study. ⋯ The results of this study suggest that the CT-based computer-assisted surgical navigation systems are precise, granting an elevated accuracy in pedicle screw positioning.

Randomized Controlled Trial
The McKenzie method compared with manipulation when used adjunctive to information and advice in low back pain patients presenting with centralization or peripheralization: a randomized controlled trial.
Randomized controlled trial. ⋯ In patients with low back pain for more than 6 weeks presenting with centralization or peripheralization of symptoms, we found the McKenzie method to be slightly more effective than manipulation when used adjunctive to information and advice.

A three-dimensional study of the thoracic pedicle (T1-T12) morphometry in Chinese patients with different body height, using reformatted computed tomography (CT). ⋯ Body height is probably one of the main factors that contribute to the variation in pedicle size among different ethnic and sex groups. Transpedicular procedures using a 4.5-mm screw may not be applicable to much of the Chinese population at the upper and middle thoracic segments, especially for patients less than 160 cm in height. A reformatted CT evaluation is routinely recommended not only for choosing the proper screw but also for determining the feasibility of a true transpedicular procedure.

A case report. ⋯ The case report highlights the clinical significance of the atypical posterior SN that could be a channel for large disc extrusion after a traumatic event in Scheuermann's disease and the clinical importance of surgeon's close attention to the possibility of abruptly progressing neurologic compromise in this situation.

Crosscultural adaptation and psychometric measurements of the Functional Rating Index (FRI). ⋯ The Persian version of the FRI seems to have an excellent reliability and validity when applied to patients with LBP.
