ObjectiveTo investigate the factors associated with the recovery process of elderly patients after degenerative lumbar scoliosis surgery.MethodsA 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.ResultsAmong 213 eligible patients, 77 (38.5%) were classified as being in the excellent group, 70 (35%) as showing improvement, 24 (12%) as showing no change, and 29 (14.5%) as having deteriorated. At baseline, patients differed significantly from matched normative data in all Scoliosis Research Society 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 (odds ratio [OR], 2.431; 95% confidence interval [CI], 1.143-5.174), and American Society of Anesthesiologists grade <3 (OR, 2.987; 95% CI, 1.519-5.874) may be predictive factors for a satisfying recovery, whereas presence of complications (OR, 0.342; 95% CI, 0.153-0.765), fusion to the sacrum (OR, 0.200; 95% CI, 0.076-0.523), and more osteotomies (OR, 0.360; 95% CI, 0.132-0.985) have negative effects on the recovery process.ConclusionsThe factors that affect postoperative recovery in elderly patients with degenerative lumbar scoliosis are age, American Society of Anesthesiologists grade, distal fusion level, presence of complications, and number of osteotomies.Copyright © 2017 Elsevier Inc.
