Comparative Study
Does obesity affect outcomes of treatment for lumbar stenosis and degenerative spondylolisthesis? Analysis of the Spine Patient Outcomes Research Trial (SPORT).
Retrospective subgroup analysis of prospectively collected data according to treatment received. ⋯ Obesity does not affect the clinical outcome of operative treatment of SpS. There are higher rates of infection and reoperation and less improvement from baseline in the SF-36 physical function score in obese patients after surgery for DS. Nonoperative treatment may not be as effective in obese patients with SpS or DS.

A case report. ⋯ Delayed anterior spinal artery syndrome after aortic coarctation repair because of anterior spinal artery thrombosis can manifest even 6 months postoperatively. Careful analysis of pre- and postoperative cross-sectional imaging should provide the correct diagnosis. Spinal digital subtraction angiography is probably unnecessary and must be interpreted with caution.

A retrospective study of modic changes (MCs) in degenerative lumbar scoliosis (DLS). ⋯ The prevalence of MCs in patients with DLS was significantly higher than that of patients without DLS. Most of them were type 2 and usually located on the concave side of apex vertebrae. MCs were significantly associated with intervertebral disc degeneration and lumbar scoliosis.

Analysis of a case series of 24 patients with Lenke 1C adolescent idiopathic scoliosis (AIS) receiving selective thoracoscopic anterior scoliosis correction. ⋯ Selective thoracoscopic anterior fusion allows spontaneous lumbar curve correction and achieves coronal balance of main thoracic and compensatory lumbar curves, good cosmesis, and patient satisfaction. Correction and balance are maintained 24 months after surgery.
