Determination of the relationship between radiographic parameters and patient-reported outcomes in Lenke type-1 adolescent idiopathic scoliosis

Abstract

Purpose: This study aims to examine sagittal alignment and spinopelvic parameters in patients with surgically treated Lenke type-1 AIS and to determine the relationship between radiographic outcomes and body image, self-esteem, disability and anxiety. Materials and methods: Twenty-five patients who underwent posterior spinal fusion surgery and followed up for more than 1 years were eveluated (mean age 14.20±1.63 years). Radiographic analysis of A/P and lateral full spine standing radiographs was carried out with the Surgimap software. The patient-reported outcomes were evaluated with Walter Reed Visual Assessment Scale, Rosenberg Self-Esteem Scale, Oswestry Disability Index and Beck Anxiety Inventory. Correlations between deformity measures and patient-reported outcomes were evaluated by the Pearson’s correlation test. Results: There was a significant decrease in Cobb angle, AVT, trunk shift, T1 tilt and pelvic incidence at early postoperative and final follow up compared with the preoperative measurement (p<0.005). Oswestry disability index was moderately negatively correlated with major curve Cobb angle (r=-0.545, p=0.007), and moderately positively correlated with pelvic tilt (r=0.478, p=0.021). There was no significant correlation between all other radiographic and patient reported outcomes (p>0.05). Conclusion: Patient-reported outcomes are important in terms of evaluating the physical and psychosocial effects of scoliosis-related deformity from the patient's perspective. However, low or no correlation was found between radiographic evaluation and patient-reported outcomes. This result indicates that objective and patient-reported results should be interpreted separately. © 2023, Pamukkale University. All rights reserved.
