To investigate retrospectively the clinical effects and recurrence rate of 143 cases who underwent one level discectomy and followed up more than 10 years. To evaluate the outcome of patients in groups of different operating age and extents of disc herniation, and analyse whether difference exists in each group. ⋯ (1) Long-term followed-up of 143 cases prove mono-level lumbar discectomy is an option for disc herniation with good curative effect and lower recurrent rate, the technique should be the prior selection in dealing with patients with lumbar disc herniation. (2) 51% patients (19/37) in group under 30 years old endure persistent low back pain.
