Background: Idiopathic scoliosis is a pathological entity of unknown etiology, characterized by a three-dimensional deformity of the spine and a low bone mass. The exact mechanism of bone loss in idiopathic scoliosis is unknown yet. However is well known that RANKL is a potent stimulator of bone resorption by binding receptor activator of nuclear factor-kB (RANK) in the osteoclasts cell membrane. OPG is a decoy receptor for RANKL, which interferes with RANKL/RANK binding and i...

Adolescent idiopathic scoliosis (IS) represents an evolutive disease that occurs in puberty and progresses till the skeletal maturation. The neuroendocrine hypothesis involving a melatonin deficiency as the source for IS is one of the proposed causes of this plurifactorial disease.Objective: To investigate the hormonal changes of both the gonadal and growth axis and circadian rhythmicity in subjects with adolescent idiopathic scoliosis compared to age ma...
