摘要
目的探讨不同壁厚的硅胶薄膜囊预防球囊扩张椎体后凸成形术(BK)并发症的作用。方法4具甲醛固定的老年女性湿润脊柱标本(T12~L5)制成24个单椎体标本,随机分为4组,刮匙在椎体前3/4制成体积约为6ml单侧或双侧的空腔,分别置入壁厚100μm和200μm的硅胶薄膜囊后注入骨水泥。结果壁厚100μm的硅胶薄膜囊包裹骨水泥后能较好控制骨水泥在椎体内分布,可嵌入到周围骨小梁内,不形成界面。而壁厚200μm的硅胶囊则不能。结论在球囊扩张椎体后凸成形术中置入壁厚100μm的硅胶薄膜囊可控制骨水泥在椎体内分布,嵌入骨小梁间隙内而不形成界面,有效预防BK手术并发症。
Objective To investigate the efficacy of silicone membrane vesicle of different thickness in preventing complication of kyphoplasty. Methods Four formalin-fixed old female spines (T12- L5) were disarticulated into 24 vertebral bodies, which were allocated into four groups. Curette was used to create spaces about 6 ml through unipedicular or bipedicular. Bone cement was injected after inserting silicone membrane vesicle of different thickness. Results Silicone membrane vesicle with the thickness of 100μm contained bone cement could manipulate the distribution of bone cement and plug in bone trabecula easily without interface, but the silicone membrane vesicle with the thickness of 200 μm could not.. Conclusion Silicone membrane vesicle of thickness 100μm can manipulate distribution of bone cement and plug in bone trabecula to prevent complication in balloon kyphoplasty.
