반월상 연골판의 뿌리파열의 심각성이 인식되면서 이에 대한 적극적인 봉합이 필요하게 되었다. 특히 후각부 뿌리 파열에 대한 봉합 방법과 결과가 최근에 많이 보고되고 있다. 그러나 전각부 뿌리 파열에 대한보고는 아직 보고된 바 없으며 이에 저자들은 과거에 시행했던 원판형 연골의 부분 절제 후 발생한 의인성 뿌리 파열과 이로 인한 아탈구를 경험하였고 이를 봉합나사를 이용하여 정복하여 좋은 결과를 얻었기에 보고하는 바이다.

Objective : We investigated the clinical and radiological advantages of unilateral laminectomy in posterior lumbar interbody fusion (PLIF) procedure comparing with bilateral laminectomy, under the same procedural condition including bilateral instrumentation and insertion of two cages, in patients with degenerative lumbar disease with unilateral leg symptoms. Methods : We retrospectively reviewed 124 consecutive cases of PLIF via unilateral or bilateral approach between January 2006 and April 2010. In 80 cases (bilateral group), two cages were inserted via bilateral laminectomy, and in 44 cases (unilateral group), via unilateral laminectomy. The average follow-up duration was 29.5 months. The clinical outcomes were evaluated with the Visual Analogue Scale (VAS) and the Oswestry disability index (ODI). The fusion rates and disc space heights were determined by dynamic standing radiographs and/or computed tomography. Operative times, intra-operative and post-operative blood losses and hospitalization periods were also evaluated. Results : In clinical evaluation, the VAS and ODI scores showed excellent outcomes in both groups. There were no significant differences in term of fusion rate, but the perioperative blood loss and the operative time of the unilateral group were lower than that of the bilateral group. Conclusion : Unilateral laminectomy can minimize the operative time and perioperative blood loss in PLIF procedure. However, the different preoperative disc height between two groups is a limitation of this study. Despite this limitation, solid fusion and satisfactory symptomatic improvement could be achieved uniquely by our surgical method. This surgical method can be an alternative surgical technique in patients with unilateral leg pain.
