METHODS: Resin embedding method and graded facetectomy and discectomy were made to prepare spinal instability models.
方法：利用腰椎后路附件逐级破坏和椎间盘切除制作腰椎不稳模型。

In addition, PLIF was also tested with either a unilateral or bilateral facetectomy to simulate commonly used surgical techniques.
此外，后路椎间融合模型还要通过在外科手术中很常用的单侧或双侧椎骨关节面切除来测试。
