Abstract

STUDY DESIGN: Prospective population-based birth cohort study OBJECTIVE:: To identify whether there is any hidden burden of disease associated with smaller spinal curves.

SUMMARY OF BACKGROUND DATA: Adolescent idiopathic scoliosis is present in 3-5% of the general population. Large curves are associated with increased pain and reduced quality of life. However, no information is available on the impact of smaller curves, many of which do not reach secondary care.

METHODS: The Avon Longitudinal Study of Parents and Children (ALSPAC) recruited over 14,000 pregnant women from the Bristol area of South-West England between 1991-1992 and has followed up their offspring regularly. At aged 15 presence or absence of spinal curvature ≥6 in the offspring was identified using the validated DXA Scoliosis Measure on 5299 participants. At aged 18 a structured pain questionnaire was administered to 4083 participants. Logistic regression was used to investigate any association between presence of a spinal curve at aged 15 and self-reported outcomes at aged 18 years.

RESULTS: Full data were available for 3184 participants. 202 (6.3%) had a spinal curve ≥6 and 125 (3.9%) had a curve ≥10 (median curve size of 11). 46.3% reported aches and pains that lasted for a day or longer in the previous month. 16.3% reported back pain. Those with spinal curves were 42% more likely to report back pain than those without (OR 1.42, 95%CI 1.00 to 2.02, P = 0.047). Those with spinal curves had more days off school and were more likely to avoid activities that caused their pain.

CONCLUSIONS: Our results highlight that small scoliotic curves may be less benign than previously thought. Teenagers with small curves may not present to secondary care, but are nonetheless reporting increased pain, more days off school and avoidance of activities. These data suggest we should reconsider current scoliosis screening and treatment practices.
