Multicenter Study Comparative Study
Prospective pulmonary function comparison of open versus endoscopic anterior fusion combined with posterior fusion in adolescent idiopathic scoliosis.
Prospective clinical study. ⋯ VAT versus Open release/anterior fusion in association with a PSF for select AIS curves requiring circumferential treatment both demonstrated similar radiographic and pulmonary function test improvement at 2 years postoperative, with no significant differences seen between the groups.

Multicenter Study
Spondylolisthesis, pelvic incidence, and spinopelvic balance: a correlation study.
A retrospective study of the sagittal alignment in developmental spondylolisthesis. ⋯ Since PI is a constant anatomic pelvic variable specific to each individual and strongly determines SS, PT, and LL, which are position-dependent variables, this study suggests that pelvic anatomy has a direct influence on the development of a spondylolisthesis.Study participants with an increased pelvic incidence appear to be at higher risk of presenting a spondylolisthesis, and an increased PI may be an important factor predisposing to progression in developmental spondylolisthesis.

Experimental spinal cord injury using a rat model. ⋯ Transplanted MSCs injected into the subarachnoid space of the lumbar spine can migrate to injured thoracic spinal cord tissue. The ratio of MSCs observed at the injury site was significantly higher than in the intact spinal cord, and also infiltrated into the deeper spinal cord parenchyma by the perivascular spaces. Lastly, some MSCs differentiated into Nestin-positive, immature neurons or glial cells.

Review Comparative Study
Long adult deformity fusions to L5 and the sacrum. A matched cohort analysis.
A matched cohort analysis of long adult deformity fusions according to distal fusion level (L5 vs. S1). OBJECTIVE.: To compare the results of long adult deformity fusions to either L5 or the sacrum in the presence of a "healthy" 5-1 disc using a matched cohort analysis. ⋯ At 3 to 5 years' mean follow-up, long adult fusions to the sacrum required more procedures and had a higher frequency of complications than similar fusions to L5. For fusions to L5, subsequent subjacent disc degeneration is common and may be associated with a forward shift in sagittal balance. The ultimate influence of these factors on long-term outcomes remains to be seen.
