Spine
-
Prospective nonscoliotic cohort evaluation of the effects of various positions for obtaining standing lateral thoracolumbar radiographs. ⋯ Standing with the hands supported while flexing the shoulders 30 degrees during positioning for lateral spinopelvic radiographic acquisition resulted in an SVA and measures of sagittal plane curvature that were comparable with a functional standing position with arms at the side. This seems to be the best way to move the arms anterior to the spine with the least effect on overall sagittal balance.

Clinical Trial
Motor control patterns during an active straight leg raise in chronic pelvic girdle pain subjects.
Repeated measures. ⋯ This MC pattern, identified during an ASLR on the affected side of the body, has the potential to be a primary mechanism driving ongoing pain and disability in chronic PGP subjects.
-
A descriptive study of the association between Schmorl nodes (SNs) and gender, ethnic origin, and age in a normal skeletal population. ⋯ SNs are a common phenomenon in the normal adult populations with almost half of the individuals in our sample manifesting at least 1 vertebra with SN. Its demographic characteristics suggest that the phenomenon is not of occupational origin, promoting the notion of genetic background.

Review Meta Analysis
Spinal mechanical load as a risk factor for low back pain: a systematic review of prospective cohort studies.
Systematic review. ⋯ We found strong evidence that leisure time sport or exercises, sitting, and prolonged standing/walking are not associated with LBP. Evidence for associations in leisure time activities (e.g., do-it-yourself home repair, gardening), whole-body vibration, nursing tasks, heavy physical work, and working with ones trunk in a bent and/or twisted position and LBP was conflicting. We found no studies, thus no evidence, for an association between sleeping or sporting on a professional level and LBP.

Multicenter Study
Treatment of thoracic scoliosis: are monoaxial thoracic pedicle screws the best form of fixation for correction?
Multicenter retrospective cohort study of 100 consecutive patients. ⋯ Similar coronal and sagittal plane correction was achieved in thoracic adolescent idiopathic scoliosis with 3 different constructs. There was a trend toward improved correction of clinical rib hump deformity with MONO screw constructs compared with POLY screw constructs.
