RhBMP-2 use in lumbar fusion surgery is associated with transient immediate post-operative leg pain.
Supra-physiological rhBMP loads during spinal fusion may trigger local inflammation and post-operative radiculitis. MRI is an effective tool to detect nerve root compression in severe post-operative leg pain. The aim of this study was to determine if recombinant bone morphogenic protein 2 (rhBMP-2) is associated with immediate post-operative leg pain without evidence of root compression using MRI. ⋯ III.

Comparative Study
Cross-cultural adaptation and assessment of the reliability and validity of the Core Outcome Measures Index (COMI) for the Brazilian-Portuguese language.
The use of patient-orientated questionnaires is of utmost importance in assessing the outcome of spine surgery. Standardisation, using a common set of outcome measures, is essential to aid comparisons across studies/in registries. The Core Outcome Measures Index (COMI) is a short, multidimensional outcome instrument validated for patients with spinal disorders. This study aimed to produce a Brazilian-Portuguese version of the COMI. ⋯ The reproducibility of the Brazilian-Portuguese version of the COMI was comparable to that of other language versions. The COMI scores correlated in the expected manner with existing but longer symptom-specific questionnaires suggesting good convergent validity for the COMI. The Brazilian-Portuguese COMI represents a valuable tool for Brazilian study-centres in future multicentre clinical studies and surgical registries.

The aim of this study was to investigate the prevalence of acute low back pain (ALBP) and associated factors in high school students from a Southern Brazilian city. ⋯ Further studies with follow-ups to adulthood are needed to investigate whether physical cumulative loads on the lumbar spine (for example, duration/transport, school bags and inadequate school furniture) during adolescence, may influence the development of ALBP later in life.

Reporting financial disclosures has become standard practice in both journal publications and during oral forum at scientific meetings. Despite this, the effect of reporting a financial disclosure of any member of an authorgroup, on the tone of the conclusion of an article has gained little attention. This study was performed to determine what effect reporting a financial disclosure has on the conclusion of an article. ⋯ Reporting a financial disclosure is a potential source of bias. Authors with disclosed financial relationships less often publish articles with a neutral/negative conclusion. This source of bias should certainly be taken into account during the critical appraisal of articles, particularly when the quality of the literature is being assessed.

Anatomical study of the relationship among the cervical nerve roots, intervertebral disc, and lateral mass is important for the neurosurgeon to avoid complications of posterior cervical foraminotomy. ⋯ Anatomic and morphologic study of the cervical nerve roots and their relationships to the lateral mass and the intervertebral disc are useful landmarks to reduce the operative complications of the posterior foraminotomy.
