Three-dimensional spring model: a new hypothesis of pathogenesis of adolescent idiopathic scoliosis.

Abstract:

:The pathogenesis of adolescent idiopathic scoliosis (AIS) has been the subject of many studies, but remains little understood. Previous work has shown that there is a correlation between the uncoupled spinal neuro-osseous growth and AIS. We believe that this uncoupled spinal neuro-osseous growth may also contribute to formation of normal curvature of the spine in the sagittal plane during the childhood. We speculate a three-dimensional spring model to better understand our hypothesis. The normal curvature of the spine, the uncoupled spinal neuro-osseous growth, and the overgrowth of the spine in the puberty may be the crucial factors in the pathogenesis of AIS.

  • Moderate osteoporosis itself is beneficial for bones.

    abstract::There have been increasing numbers of reports that anti-osteoporosis drugs cause osteonecrosis. A typical example is medication-related osteonecrosis of the jaws (MRONJ) which can cause massive necrosis and defects of the jaws. Thus, the dosage and effects of anti-osteoporosis drugs should be re-examined. Our hypothes...
