  • Correlative Factors for the Efficacy of Surgical Treatment for Single Segment Degenerative Lumbar Spinal Disorders

    ObjectiveTo investigate the correlative factors for the efficacy of surgical treatment for single segment degenerative lumbar spinal disorders. MethodsFrom October 2008 to November 2010, a prospective non-randomized controlled study was carried out on 179 patients who were diagnosed to have L4-5 degenerative lumbar spinal disorders and underwent surgical treatment. Ninety-seven patients were included in our study, including 64 males and 33 females, aged between 21 and 86 years old, averaging 49.0. The follow up lasted for an average of 18.9 (12-27) months. The correlative factors including age, sex, body mass index, preoperative psychological state and degree of low back pain, surgical methods, combination with adjacent segment degeneration and recurrence state were analyzed. Single and multiple-factor Logistic regression analysis was used to determine the relationship between independent factors and surgical results of lumbar degenerative disease. ResultsAt the last follow-up, Japanese Orthopaedic Association scores were improved to 22.40±3.18 with an improving rate of (68.5±15.7)% compared with the preoperative condition (7.61±3.09), and the difference was significant (t=-33.031, P<0.001). Univariate analysis showed that all factors were variables associated with the surgical results excluding sex and age (P<0.05). Multiple-factor logistic regression analysis showed that the preoperative psychological state, combination with adjacent segment degeneration and surgical methods had important impact on the surgical results (P<0.05). ConclusionSurgical treatment of lumbar degenerative disease is effective. The preoperative psychological state, combination with adjacent segment degeneration and surgical methods are important factors associated with the surgical results.
