Extraforaminal Lumbar Disc Herniations – A Report of Four Cases

脊間孔外腰椎間盤突出病的外科治療 - 四病例報告

摘要


民國七十四年七月到七十八年十二月,共有204位病人在長庚醫院接受腰椎間盤切除術。其中四位為脊間孔外椎間盤突出病,其發生率為1.9%。診斷上,電腦斷層可以精確的顯示病狀,同時提供醫師較佳的手術途徑。臨床上,這些病例表現的症狀與傳統的病例並無多大差別。平均年齡(48.5)歲顯示略為偏高。手術方法建議採經橫突間韌帶途徑,其優點是不會破壞脊椎關節或峽部,避免日後脊椎不穩定的發生。

From July 1985 to December 1989, 204 patients were operated on for lumbar disc herniations at chang Gung Memorial Hospital. Four of them were diagnosed as extraforaminal disc herniations and the diagnosis was verified by operation. The incidence was 1.9%. Computed tomographic (CT) scanning can demonstrate the lesions precisely and can direct the surgeon in approaching the lesion sites. The clinical findings wer not much different from those of classic disc herniation. A little older population was noted with an average age of 48.5 years (46 to 52 years). Surgical approach via the intertransverse ligament is recommemded for extraforaminal disc herniations. It causes less trauma to the facet joint and isthmus. Late spinal instability might be prevented.
