Abstract: Objective To investigate the influencing factors of degenerative lumbar scoliosis (DLS) in elderly patients with lumbar spinal stenosis (LSCS), and to provide reference for clinical prevention and treatment of DLS. Methods A total of 296 elderly patients with LSCS admitted to our hospital from January 2017 to January 2022 were retrospectively selected and divided into DLS group (74 cases) and non-DLS group (222 cases). Demographic, clinical and imaging data of the patients were collected, and multivariate Logistic regression was used to analyze the risk factors for DLS in elderly LSCS patients. Results The proportions of age ≥70 years old, female, body mass index ≥25, osteoporosis, sarcopenia in DLS group were higher than those in non-DLS group (P<0.05), Pfirrmann grade 4-5, scoliosis Cobb angle, L3 tilt angle, pelvic incidence(PI), pelvic tilt(PT), sagittal vertical axis(SVA) in DLS group were larger than those in non-DLS group, and lumbar lordosis(LL)and sacral slope(SS)in DLS group were less than those in non-DLS group (P<0.05). Logistic regression showed that age ≥70 years, osteoporosis, sarcopenia, Pfirrmann grade 4-5, PI and SVA were risk factors for DLS in elderly LSCS patients (P<0.05), and LL was a protective factor (P<0.05). Conclusions Age, osteoporosis, sarcopenia, Pfirrmann grade 4-5, LL, PI and SVA are related to the occurrence of DLS in elderly LSCS patients. Clinical intervention and treatment for high-risk patients should be strengthened to prevent and reduce the occurrence of DLS.
