PMMA填充在髂后上棘取骨后的止血效果探讨

Hemostasis effects of using PMMA to reconstruct iliac bone defect after iliac bone harvesting

目的探讨聚甲基丙烯酸甲酯(PMMA)填充髂后上棘取骨区的止血效果。方法对14例使用PMMA填塞髂后上棘取骨区与64例髂后上棘取骨后使用骨蜡封闭创面患者进行回顾性分析,比较术后引流量变化情况、术后疼痛评分、引流管拔管时间。结果 PMMA填塞与骨蜡封闭比较,引流量以及拔管时间均显著降低(P<0.05)。术后第1天两者疼痛评分差异无统计学意义(P>0.05),术后第2、3、5、7 d疼痛评分PMMA组较骨蜡封闭组均显著下降(P<0.05)。PMMA并发症发生率为7.14%,较骨蜡封闭的37.5%低(P<0.05)。结论使用PMMA填充取骨区骨缺损能有效减少术后渗出,减轻术后疼痛以及降低术后并发症的发生几率,可在临床髂后上棘取骨中广泛应用并加以推广。

Objective To evaluate hemostasis effect by using PMMA to reconstruct iliac bone defect after iliac bone harvesting. Methods 78 patients were divided into two groups. 14 patients were accepted by using PMMA to fill the bone defect. 64 patients were accepted bone wax. The doctor was required to record pain degree and the drainage volume during postoperative first, second ,third, fifth, seventh day re- spectively and the drainage tube removal time. Results The results showed that the first day after surgery,the pain scale was no significant difference between two groups （P 〈 0. 05 ）. On the second, third, fifth, seventh day, respectively, the PMMA group was significantly lower than that in the control group （P 〈0.05）. The drainage of PMMA group were significantly lesser than were in the control group （P 〈0.05）. The removal time of the PMMA group was also shorter than was in the control group. Conclusion Using PMMA to reconstruct the bone defect of donor sites can be concerned a new method.
