The authors describe a technique whereby a portion of the lamina removed during exposure of an intervertebral lumbar disc protrusion is implanted in the intervertebral disc space following disc excision. An analysis of 456 consecutive cases operated on by this technique and followed from 1 to 10 years is presented. Of the 418 patients followed, 92 per cent indicated they were able to return to their normal activities and were satisfied with the result. Thirty percent of the patients indicated they had required some conservative treatment for recurrent episodes of back or leg pain. Ten patients had subsequent back surgery; only one implant has dislocated.
作者描述了一种技术，即在腰椎间盘突出症暴露过程中切除的部分椎板，在椎间盘切除后植入椎间盘间隙。本文对连续456例采用该技术手术并随访1至10年的病例进行了分析。在随访的418例患者中，92%表示能够恢复正常活动并对结果满意。30%的患者表示因背部或腿部疼痛复发需要一些保守治疗。10例患者随后接受了背部手术；只有1枚植入物发生了移位。
