SRS-22r Self-Image After Surgery for Adolescent Idiopathic Scoliosis at 10 Year Follow-up

Abstract

Study Design. Retrospective cohort Objective. To examine SRS-Self Image scores at up to 10 years after surgery for adolescent idiopathic scoliosis (AIS). Summary of Background Data. Self-image is complex with implications for surgical and patient-reported outcomes after AIS surgery. Surgically modifiable factors that impact self-image are inconsistently reported in the literature with few longer-term reports. We examined the rate and durability of self-image improvement. Materials and Methods. An AIS registry was queried for patients with up to 10 years of follow-up after AIS surgery. A mixed effects model estimated change in SRS-22 Self Image from baseline to 6 weeks, 1 year, 2 years, 5 years, and 10 years. All enrolled patients contributed data to the mixed effects models. A sub-analysis of patients with 1-year and 10-year follow-up evaluated worsening/static/improved SRS-22 Self Image scores examined stability of scores over that timeline. Baseline demographic data and 1-year deformity magnitude data were compared between groups using parametric and nonparametric tests as appropriate. Results. Data from 4608 patients contributed data to the longitudinal model; 162 had 1-year and 10-year data. Mean SRS-Self Image improvement at 10-year follow-up was 1.0 (95% CI: 0.9–1.1) point. No significant changes in Self-Image domain scores were estimated from 1-year to 10-year (all P>0.05) postoperative. Forty (25%) patients had SRS-Self Image worsening from 1 year to 10 years, 36 (22%) improved, and 86 (53%) were unchanged. Patients who worsened over 10 years had lower SRS-Self Image at baseline than those unchanged at enrollment (3.3 vs. 3.7, P=0.007). Neither radiographic parameters nor SRS-Mental Health were different at baseline for the enrolled patients. Conclusion. Ten years after surgery, 75% of patients reported similar or better SRS-Self Image scores than one year after surgery. Nearly 25% of patients reported worsening self-image at 10 years. Patients who worsened had lower baseline SRS-Self Image scores, without radiographic or mental health differences at baseline or follow-up.

Cosmetic evaluation in type II congenital scoliosis with long-spanned curve: a case-matched comparison with adolescent idiopathic scoliosis

“…Thus, gathering patient input in the surgical planning phase is critical to ensuring a favorable postoperative outcome ( 21 - 23 ). The SRS-22 questionnaire, currently the most widely used tool for assessing health measures across different clinical domains, has been validated among different types of patients with scoliosis ( 24 , 25 ). In this study, we found that patients with CS exhibited significantly lower scores in self-image and mental health domains than those in patients with AIS.…”
