Abstract
Purpose. To evaluate outcome measures and the factors affecting them in patients treated between 1962 and 2000 at Loewenstein Rehabilitation Hospital, Israel.
Method. This retrospective cohort study included 262 patients with spinal neurological lesions (spinal cord or cauda equina lesions) following degenerative spinal stenosis. Data were collected retrospectively. Survival was assessed using the Kaplan-Meier method and the relative mortality risk by the Cox model. Neurological recovery was evaluated by the change in Frankel grades, and factors that affect it were assessed by logistic regression. Associations of length of stay in rehabilitation were analyzed with ANOVA.
Results. Median age at lesion onset was 61 years and median survival 17.6 years. Age at spinal neurological lesion onset was found to be the only factor with a significant effect on survival. Of the 148 patients who had Frankel grades A, B, or C on admission, 58% achieved recovery to grades D and E. Frankel grade at admission, age, and spinal neurological level had a significant effect on recovery. The mean length of stay was 99.7 days, and only Frankel grade had a significant effect on length of stay.
Conclusions. Patients with spinal stenosis and disabling spinal neurological lesions can achieve significant neurological recovery and survive for many years. They require adequate care in a specialist rehabilitation system.
