Abstract

To investigate the factors associated with the recovery process of elderly patients following degenerative lumbar scoliosis surgery.A total of 213 elderly patients who had undergone surgical treatment for degenerative lumbar scoliosis from 2011 to 2015 were included retrospectively in this study. Clinical data and demographics were collected for logistic regression analysis.Among 213 eligible patients, 77(38.5%) were classified as being in the excellent group, 70(35%) as improvement, 24(12%) as no change, and 29(14.5%) as deteriorate. At baseline, patients differed significantly from matched normative data in all SRS domains. Larger differences from normative values were found for Pain and Activity domains. After surgery, each domain improved significantly. In the multivariate logistic regression, age 60-70 years old (odds ratio=2.431, 95% confidence interval 1.143-5.174), ASA grade <3 (odds ratio= 2.987, 95% confidence interval 1.519-5.874) may be predictive factors for a satisfying recovery. While presence of complications (odds ratio= 0.342, 95% confidence interval 0.153-0.765), fusion to the sacrum (odds ratio= 0.200, 95% confidence interval 0.076-0.523) and more numbers of osteotomies (odds ratio= 0.360, 95% confidence interval 0.132-0.985) pose negative effects on the recovery process.The factors which affect postoperative recovery in elderly patients with degenerative lumbar scoliosis are age, ASA grade, distal fusion level, presence of complications and numbers of osteotomies.
