Operation for Recurrent Herniated Intervertebral Disc of Lumbar Spine Twenty-Five Cases Followed 2 Years~ 9 Years

並列摘要


Twenty-five patients who underwent reoperation for new complaints following initial lumbar intervertebral disc surgery were evaluated retrospectively. The pain- free interval ranged from one month to seventeen years, with an average of 44 months. The indications for operation are (1) Failure of conservative treatment and (2) Neurological deficit. Operative methods included minimal laminectomy and diskectomy. Spine fusion was required in six patients who had concomitant instability, or chronic back pain. They were followed up 2 to 9 years with an average of 3 years and 10 months. The evaluation of the post-operative functional results is according to the method suggested by B.O. Jonsson13.There were excellent in 9, good in 14 (total 92%), and fair in 2 patients. We concluded that sudden onset of sciatica after a pain-free interval ins highly suspicious of recurrent disc herniation and operation for recurrent HIVD may have as good result as primary disc surgery. Repeat laminectomy and diskectomy is the treatment of choice for recurrent HIVD without instability. Spine fusion is only indicated when concomitant instability exists.
