摘　　要：极外型腰椎间盘突出症是指神经根受压于神经根管外侧的椎间管腰椎间盘突出症。临床少见，本组共３例。１例为椎间管外，２例为椎间管内。由于症状与普通根型腰椎间盘突出症相似，术前难以鉴别。具有典型腰椎间盘突出症状。手术探查阴性或突出物不能解释临床症状时，要考虑本症。注意观察神经根走向、敏感度及张力，发现异常则扩大探查。该症要求手术暴露广，椎弓切除范围大，术后是否会出现椎体间不稳，尚待继续观察。Extremely lateral lumbar intervertebral disc protrusion(ELLIDP) is uncommon, in which condition,the nerve root is pressed by the nucleus pulposus situated outside of radicular canal. There are 3 cases in our series. One of them has extraforaminal lumbar disc protrusion, and the other two have intraforminal lumbar protrusion, It is difficult to recognize ELLIDP because the clinical signs is similar to general lateral lumbar intervertebral disc protrusion.If a patient has typical sign of lumbar intervertebral disc protrusion and the operative exploration shows a negative result or the protrusion can not explain the clinical sign,ELLIDP should be considered.During the operation,it is necessary to observe the trend,sensitivity and tension of the root carefully,When there is some abnormal condition,the exploration should be extended.ELLIDP requires a wide-exposed operation and the vertebral arch should be resected widely.Whether the spine would be unstable after the operation need further observation.
