The traditional midline posterior approach for lumbar decompression and fusion traumatizes some paraspinous tissue. 传统后方中线入路进行腰椎减压融合使一些棘突旁组织受到损伤。
To offer the basis for the posterior approach with spinous process osteotomy through observing the different pathological changes of the supraspinous ligaments being undergone unilateral or bilateral stripped paraspinous muscles. 观察一侧与两侧剥离骶棘肌对棘上韧带组织结构影响的差异,为棘突截骨入路提供病理学依据。
In the fundamental research, the specimens from the supraspinous ligaments undergone bilateral stripped paraspinous muscles shown that the collagen fibers arranging disorderly were denaturated, inflammatory cells infiltrated, and density were uneven. 基础研究显示,两侧切开剥离骶棘肌术后的棘上韧带标本均表现出胶原纤维排列紊乱、变性,炎细胞浸润,密度不均,细胞明显变性;
