Abstract

Background

Prospective data on health-related quality of life in patients with idiopathic scoliosis treated surgically as adults is needed. We compared preoperative and 1- and 2-year follow-up data in surgically treated adults with idiopathic scoliosis with juvenile or adolescent onset. Results were compared to untreated adults with scoliosis and population normative data.

Methods

A comparison of preoperative and 1- and 2-year follow-up data of 75 adults surgically treated for idiopathic scoliosis at a mean age of 28 years (range 18 to 69) from a prospective national register study, as well as a comparison with age- and sex-matched data from 75 untreated adults with less severe scoliosis and 75 adults without scoliosis, was made. Outcome measures were EuroQol-5 dimensions (EQ-5D) and Scoliosis Research Society (SRS)-22r questionnaire.

Results

In the surgically treated, EQ-5D and SRS-22r scores had statistically significant improvements at both 1- and 2-year follow-ups (all p  < 0.015). The effect size of surgery on EQ-5D at 1-year follow-up was large (r = −0.54) and small-medium (r = −0.20) at 2-year follow-up. The effect size of surgery on SRS-22r outcomes was medium-large at 1- and 2-year follow-ups (r = −0.43 and r = −0.42 respectively). At the 2-year follow-up, the EQ-5D score and the SRS-22r subscore were similar to the untreated scoliosis group (p = 0.56 and p = 0.91 respectively), but lower than those in the adults without scoliosis (p < 0.001 for both comparisons).

Conclusions

Adults with idiopathic scoliosis experience an increase in health-related quality of life following surgery at 2-year follow-up, approaching the health-related quality of life of untreated individuals with less severe scoliosis, but remain lower than normative population data.
