The lumbar disc herniations were located at L(3,4). in one patient, L(4,5) in 10 cases and L5S1 in 5 cases.</p><p><b>RESULTS</b>All the patients were followed up, and the duration ranged from 20 to 48 months, with a mean period of 36 months. According to Macnab evaluation, 12 cases got an excellent result, 4 good. No apparent complications related to the technique occurred.
