Older adult idiopathic scoliosis patients have greater improvement in self-image compared to younger adult and adolescent idiopathic scoliosis patients following posterior spinal fusion
摘要
The complex relationship between spine deformity and self-image is incompletely understood. This study aims to evaluate how age affects self-image in idiopathic scoliosis.
MethodsSingle-center study of adult (AdIS) and adolescent (AIS) idiopathic scoliosis patients treated with posterior spinal fusion (PSF). Preoperative and two-year postoperative patient-reported, radiographic, and perioperative outcomes were compared. Patients were grouped according to age, AIS (< 1 8 years), young adults (yAdIS, 18–40 years) and older adults (oAdIS, > 40 years).
Results176 patients were included, 54 AIS (ave. 15.8 years), 47 yAdIS (mean 25.2 years), and 74 oAdIS (mean 56.5 years). Preoperative curve magnitude was similar between groups (p = 0.0863). Postoperative, AIS and yAdIS had similar curves, but smaller than oAdIS (p = 0.0104) with similar corrections (p = 0.6476). AIS had lower EBL (p < 0.0001), shorter OR times (p < 0.0001), fewer levels (p < 0.0001) and pelvic instrumentation (p < 0.0001). AIS had greater preoperative self-image scores (3.5 vs. 3.1 vs. 2.5, p < 0.0001) with no difference seen postoperative (4.4 vs. 4.3 vs. 4.2, p = 0.1230). However, the greatest improvement was observed in oAdIS patients (p < 0.0001). Independent predictors of self-image scores varied by age and included anxiety/depression (β = − 1.057), BMI (β = 0.033), and postoperative CVA (β = − 0.021) for AIS; anxiety/depression (β = − 0.513) and curve correction (β = 0.0143) in yAdIS; and postoperative pelvic tilt (β = − 0.028, p = 0.0037) for oAdIS.
ConclusionAIS patients had the highest preoperative self-image scores, followed by yAdIS and then oAdIS. However, the greatest improvement was observed in the older patients, despite more surgical morbidity. Mental health diagnoses were associated with worse self-image scores in AIS and yAdIS, though not oAdIS.
