Genetic predisposition seems to be necessary, but there remains an elusive environmental trigger. It could be increased Osteopontin levels, decreased melatonin levels, CNS infection (viral), trauma, or a little bit of all o them and some we haven't even discovered yet....and the search continues...

Study Design. The report of 2 cases and review of the literature.
Objective. To report the cases of a pair of female monozygotic
(high-class athletes) twins discordant for adolescent idiopathic
Summary of Background Data. The relation between scoliosis and
exercising is rather unclear. The latter has often been considered both
as a therapeutic means and a causative factor of the former. The
existence of genetic predisposition in the development of adolescent
idiopathic scoliosis is commonly accepted. According to the best of our
knowledge, this is the first report of a pair of female monozygotic
(high-class athletes) twins, discordant for adolescent idiopathic
Methods. A pair of 13.5-year-old female monozygotic twins, high-class
level athletes of synchronized swimming, was clinically examined during
a school screening program. Both girls were observed in the standing
erect position for asymmetries of the lateral contours of the trunk,
shoulders, and scapulas and their limb's length was measured. The
"forward bending test" was performed to determine the existence of rib
Results. One of the sisters was considered to be suspicious of
suffering from scoliosis. The radiologic evaluation that followed
confirmed the existence of adolescent idiopathic scoliosis (left
thoracolumbar curve of 32 as measured by the Cobb angle). The clinical
and radiologic evaluation of her sibling failed to reveal the existence
of any spinal deformity.
CONCLUSION. Adolescent idiopathic scoliosis seems to be a
multifactorial skeletal disorder. The role of exercising and heredity in its development remain controversial.
