  • Abstract
  • Look Inside

 Microendocopic discectomy was performed for lumbar disc herniatoin in 402 consecutive patients between September 1998 and December 2003. There were 262 men and 140 women, and the patients' average age was 37.9±14.9. There were 386 cases of lumbar disc herniation, and 16 cases of posterior endoplate lesions. The surgical outcomes showed an improvement in JOA score for lumbar disc herniation from 13.4±5.1 to 26.3±3.1 postoperatively;moving to 27.6±2.2 in the final follow up. Complications occurred in 16 cases (4.0%). Specifically, there were dural tears, (6 cases), misjudgment of the operative site, (3 cases), post-operative hematoma, (4 cases), pyogenic osteomyelitis, (1 case), and transient motor weakness, (2 cases). The re-operation rate was 3%, 12 cases. These consisted of recurrence of disc herniation (9 cases), postoperative hematoma (2 cases) and insufficient decompression (1 case). MED affords not only less invasive surgery, but also offers the advantages of endoscopic surgery. Therefore, MED can be indicated for all types of lumbar disc herniation and may produce good clinical outcomes, if sufficient endoscopic surgical skill is attained.
