  • Look Inside

I investigated the incidence of post-operative residual numbness and the factors which influenced that with lumbar disc herniation and lumbar spinal canal stenosis. In lumbar disc herniation,there were 84% of patients who complained of numbness preoperatively. The incidence of residual numbness was 26% in patients one year after the operation. The factor that influenced residual numbness was the age of the patient at operation. In lumbar spinal canal stenosis,there were 89% of patients who complained of numbness preoperatively. The incidence of residual numbness was 45% in patients 1 year after the operation. The factors that influenced residual numbness were the pre-operative JOA score,muscle weakness and the duration of symptoms. It is speculated that the power of recovery of neural tissues is important when considering residual numbness in lumbar disc herniation,and for lumbar spinal canal stenosis the existence of irreversible change is important.
