| ABSTRACT |
|
Nine patients, who had once low back operation due to herniated lumbar disc, underwent repeated low back surgery at the same level because of persistent or recurred symptoms. All patients were proved to have no psychological or compensative problems. Seven of them had satisfactory results but two, one who had no definite symptom free interval and had surgically proven epidural fibrosis only and another who underwent reoperation as early as 45 days after the first operation had persistent previous symptoms.
After review of these cases we obtained several favorable factors which influence the post-operative results. When a patient had a definite symptoms free interval longer than 2 years or the main offending lesion was proved to be a disc herniation or spinal stenosis, satisfactory results could be anticipated. |
