Neck and back problems in adults with idiopathic scoliosis diagnosed in youth: An observational study of prevalence, change over a mean four year time period and comparison with a control group

Abstract

Background: The knowledge is sparse concerning neck problems in patients with idiopathic scoliosis. This is an observational study including a control group which aims to describe the prevalence of neck problems and the association with back problems among adult individuals with and without idiopathic scoliosis. Methods: One thousand sixty-nine adults with a mean age of 40 years, diagnosed with idiopathic scoliosis in youth, answered a questionnaire on neck and back problems. Eight hundred seventy of these answered the same questionnaire at a second occasion in a mean of 4 years later. Comparisons were made with a cross-sectional population-based survey of 158 individuals. Statistical analyses were made with logistic regression or analysis of variance, adjusted for age, smoking status, and sex. Results: Individuals with scoliosis were previously untreated (n = 374), brace treated (n = 451), or surgically treated (n = 244). Of the individuals with scoliosis, 42% (n = 444) had neck problems compared to 20% (n = 32) of the controls (p = 0.001). The prevalence of neck problems was not affected by the type of treatment (p = 0.67) or onset of scoliosis; juvenile (n = 159) or adolescent (n = 910; p = 0.68). Neck and/or back problems were experienced by 72% of the individuals with scoliosis and 37% of the controls (p < 0.001). Of the individuals with scoliosis having neck problems, 81% also reported back problems, compared to 59% of the individuals in the control group (p < 0.001). The prevalence of neck and back problems was similar at the second survey. Conclusions: Neck problems are more prevalent and more often coexist with back problems in individuals with idiopathic scoliosis than in controls. The majority of individuals have persisting problems over time.
