P51. Which subscales of Oswestry Disability Index and Short Form 36 are related with sagittal and coronal parameters in degenerative lumbar scoliosis patients: a prospective study
The Spine Journal(2022)
Abstract
BACKGROUND CONTEXT
Degenerative lumbar scoliosis (DLS) patients had various degrees of disability. Previous studies have been inconclusive as to the correlation between radiographic and clinical parameters in DLS.PURPOSE
The aim of this study was to identify the relationship between Oswestry Disability Index (ODI) and Short Form 36 (SF-36) total and subscale scores and global spinal parameters in DLS patients.STUDY DESIGN/SETTING
A prospective study.PATIENT SAMPLE
We enrolled 126 consecutive patients with degenerative de novo lumbar or thoracolumbar scoliosis patients who were referred to a tertiary hospital between August 2018 and December 2019.OUTCOME MEASURES
ODI and SF-36 total and subscale scores.METHODS
Sagittal (sagittal vertical axis; thoracic kyphosis; lumbar lordosis [LL]; pelvic tilt; pelvic incidence [PI]; PI-LL) and coronal (Cobb angle [CA]; coronal C7 plumb line; pelvic obliquity) parameters were measured on whole spinal radiographs. Pearson's correlation analysis was performed to reveal the relationship between parameters.RESULTS
There were 76 female and 15 male patients with an average age of 70.2±8.4 years. The CA averaged 18.9±8.0°. ODI total score and SF-36 PCS had correlations with only coronal spinal parameters. ODI walking, standing, social life, and traveling domains were correlated with both coronal and sagittal parameters. Pain intensity, personal care, lifting, sitting and sex life domains were correlated with only coronal parameters. SF-36 physical function (PF) domain had correlations with both coronal and sagittal parameters. Bodily pain and vitality domains had correlations with only coronal parameters.CONCLUSIONS
Only coronal parameters were correlated with ODI total score and SF-36 PCS in DLS patients. Coronal parameters were also correlated with most ODI subscales and SF-36 PF, BP and VT subscales. Although sagittal parameters were not correlated with ODI total score and SF-36 PCS, those were correlated with some subscale scores of ODI (walking, standing, social life and traveling) and SF-36 PF subscale. Analysis using subscale scores of ODI and SF-36 is helpful to understand and treat various degree of disability in DLS patients.FDA DEVICE/DRUG STATUS
