Multicenter Study
Predictors of change in postoperative pulmonary function in adolescent idiopathic scoliosis: a prospective study of 254 patients.
A multicenter study of prospectively collected pulmonary function testing and radiographic measures in patients surgically treated for adolescent idiopathic scoliosis (AIS). ⋯ Aside from preoperative PFT values, open anterior approaches predict the largest percent of variance in 2-year PFT. Additionally, a clinically significant reduction in the predicted 2-year pulmonary function is more likely when performing a thoracoplasty. The magnitude of the effects for both these variables, however, is modest. This may facilitate the decision-making process as regards to operative intervention.

Comparative Study
Psychiatric comorbidity in chronic disabling occupational spinal disorders has minimal impact on functional restoration socioeconomic outcomes.
A prospective study conducted at a tertiary functional restoration center for patients with chronic disabling occupational spinal disorders (CDOSDs), comparing treatment outcome status 1-year posttreatment of patients with specific diagnosed psychiatric disorders to those without. ⋯ Despite intensive management of psychiatric disorders during interdisciplinary functional restoration for CDOSD, several disorders were found to be associated with less successful outcomes. Poorer work outcomes were more common with specific (and comorbid) Axis I psychiatric disorders. Opioid dependence was the single disorder associated most often with less successful outcomes. Despite these findings, the large majority of patients demonstrated successful outcomes. Depression did not independently link to less successful outcomes.

Multicenter Study Comparative Study
Construct validity of the physical function scale of the Swiss Spinal Stenosis Questionnaire for the measurement of walking capacity.
Measurement (validity) study using data from a prospective longitudinal study of lumbar spinal stenosis. ⋯ Results support construct validity of the Physical Function Scale for the measurement of walking in an lumbar spinal stenosis population. However, it cannot be ascertained from the current study that the construct being measured is, indeed, walking capacity. Further research is warranted to investigate criterion validity evidence for the use of the Physical Function Scale in the measurement of walking capacity in lumbar spinal stenosis, by examining the relationships between self-report and observational measures of walking.

Randomized Controlled Trial
Efficacy of epidural perineural injections with autologous conditioned serum for lumbar radicular compression: an investigator-initiated, prospective, double-blind, reference-controlled study.
Prospective, double-blind, reference-controlled, investigator-initiated, single center. ⋯ ACS is an encouraging treatment option for patients with unilateral lumbar radicular compression. The decrease in pain was pronounced, clinically remarkable, and potentially superior to steroid injection.

Translation, cross-cultural adaptation and psychometric testing of self-report outcome measurements. ⋯ The results of this study indicate that the Brazilian-Portuguese versions of the FRI and RMDQ are reliable and valid instruments for the measurement of disability in Brazilian-Portuguese-speaking patients with LBP presenting for physiotherapy treatment. Both instruments are suitable for use in clinical practice and research studies.
