We received THIS ARTICLE from Michael Mullin, ATC, PTA on idiopathic scoliosis. 

“In all children with so-called idiopathic scoliosis limited adduction of the right hip was found, or even abduction contracture of this hip, often connected with flexion and external rotation contracture.” 

This is a great article that discusses the etiology of scoliosis and how it relates to abnormal hip movement.
