Randomized Controlled Trial Comparative Study
Allograft versus no graft with a posterior multisegmented hook system for the treatment of idiopathic scoliosis.
A prospective, randomized study. ⋯ Our results suggest that a PSF using newer-generation multisegmented hook-screw and rod systems can be successful with allograft and/or local bonegraft without the use of supplemental autogenous bone graft (from the iliac crest or ribs) in patients with AIS.

Randomized Controlled Trial Comparative Study
Unilateral enucleation affects the laterality but not the incidence of scoliosis in pinealectomized chicken.
Randomized prospective study using an experimental scoliosis model in a pinealectomized chicken. ⋯ Unilateral visual impairment does not have a significant effect on the overall incidence and magnitude of scoliosis in the pinealectomized chicken. It does affect the laterality of the curves though, visually impaired subjects having a significantly higher likelihood of left thoracic curves, regardless of the side of blindness. It may be worthwhile to see if such an association is present in human beings as well.
