This study investigated the clinical and radiographic features associated with lumbar canal stenosis in patients over 70 years of age (group A) and compared them with patients under 60 years of age (group B).
Clinical results were evaluated using JOA score and recovery rate using Hirabayashi's method. In group A, the preoperative mean score was 12.4 points and the mean recovery rate was 70.9%. In comparison, in group B, they were 15.3 points and 85.4% respectively. The degree of leg pain, disturbance of gait and ADL in group A was significantly more severe than that in group B.
According to radiographic findings in group A, degenerative lumbar scoliosis which may aggravate symptoms was often found.
