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.

Clinical guidelines provide similar recommendations for the management of new neck pain and low back pain (LBP) but it is unclear if general practitioner's (GP) care is similar. While GP's management of LBP is well documented, little is known about GP's management of neck pain. We aimed to describe GP's management of new neck pain and compare this to GP's management of new LBP in Australia between April 2000 and March 2010. ⋯ This is the first time GP management of a new episode of neck pain has been documented using a nationally representative sample and it is also the first time that the management of back and neck pain has been compared. Despite guidelines endorsing a similar approach for the management of new neck pain and LBP, in actual clinical practice Australian GPs manage these two conditions differently.

To analyze the three-dimensional distribution of high-intensity zone (HIZ) in lumbar disks and to assess the correlation between low back pain (LBP) and spatial distribution of HIZs. ⋯ High-intensity zones occurred frequently at lower segments, inferior part of annulus fibrosus, and single disk.

Cognitive behavioral interventions are recommended as non-invasive treatment options for patients with chronic low back pain (CLBP). However, most treatment effects are small and short-lived. Although a 2-week intensive pain management program for patients with CLBP seems to be effective, the long-term results are not known. The purpose of this study is to evaluate the stability of the 2-year follow-up results and whether this is reflected in the use of health-care services. ⋯ The gained results from selected and motivated patients with longstanding CLBP at 1-year follow-up are stable at 2-year follow-up. Above all, most of the participants are at work and results indicate that the use of both pain medication and health care have decreased substantially.

Clinical outcomes of the stand-alone cage have been encouraging when used in anterior cervical discectomy and fusion (ACDF), but concerns remain regarding its complications, especially cage subsidence. This retrospective study was undertaken to investigate the long-term radiological and clinical outcomes of the stand-alone titanium cage and to evaluate the incidence of cage subsidence in relation to the clinical outcome in the surgical treatment of degenerative cervical disc disease. ⋯ The results suggest that the clinical and radiological outcomes of the stand-alone titanium box cage for the surgical treatment of one- or two-level degenerative cervical disc disease are satisfactory. Cage subsidence does not exert significant impact upon the long-term clinical outcome although it is common for the stand-alone cages. The cervical lordosis may be more important for the long-term clinical outcome than cage subsidence.
