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.

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 ( = 374), brace treated ( = 451), or surgically treated ( = 244). Of the individuals with scoliosis, 42% ( = 444) had neck problems compared to 20% ( = 32) of the controls ( = 0.001). The prevalence of neck problems was not affected by the type of treatment ( = 0.67) or onset of scoliosis; juvenile ( = 159) or adolescent ( = 910;  = 0.68). Neck and/or back problems were experienced by 72% of the individuals with scoliosis and 37% of the controls ( < 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 ( < 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.
