Scoliosis distribution
Skevimc
The distribution of Scoliosis fits your hypothesis.
Juvenile Scoliosis occurs in roughly equal numbers among boys and girls. Juvenile boys and girls have roughly the same muscles mass.
Adolescent Scoliosis occurs far more frequently in girls than boys. Adolescent girls have far less muscle mass than boys.

"Something" causes an imbalance in the spinal column. Under normal circumstances, the body can either recruit extra muscle to help stabilize and/or the imbalance is small enough so the muscles are able to 'catch-up' to the imbalance and continue doing their stabilizing thing. In abnormal circumstances, the muscles are not able to stabilize and the imbalance continues. The body will inevitably try to recruit other muscles to improve stability (if the body even senses the imbalance). Failing to correct the imbalance would then result in a spinal curve. At any point prior to permanent disc or vertebral damage/wedging, the body would, in theory, be capable of stabilizing with musculature, i.e. spontaneous correction or curve stability. If the growth is too fast and/or the body can not coordinate or train an effective spinal stability muscle pattern, the imbalance remains giving a progressive curve.

Adolescent Scoliosis occurs far more frequently in girls than boys. Adolescent girls have far less muscle mass than boys.
