Selective screening for scoliosis

Scoliosis screening has been practiced for nearly 50 years and has provided valuable knowledge about the prevalence and natural history of scoliosis. Early diagnosis allows for nonoperative treatment, like wearing an orthosis that has been shown to be effective by numerous outcome studies. Challenges in scoliosis screening include the low prevalence rate of clinically significant scoliosis, the inverse relationship of sensitivity and specificity in the screening process because of the poor correlation of clinical deformity and radiographic abnormality, and the inflated cost of these programs because of overreferral. Recommendations for improvement include redefinition of what actually constitutes a "significant" scoliosis for screening, diagnostic, and outcome purposes; selective screening of only immature females; the use of objective referral criteria; and re-screening patients rather than referring those who have borderline cases.
