Abstract

In 68 rabbits, osteotomies of the femoral medial condyle were fixed with either liquid n-buty-2-cyanoacrylate, bone cement and biodegradable polyglycolic acid (PGA) thread, or PGA thread only. Follow-up times were 1, 3, 6, 12, 24, and 48 weeks. Macroscopic, radiographic, histologic, microradiographic, and oxytetracycline labeling studies were performed. Microscopically, the medial condyles fixed with the combined materials healed in 8 of 34 rabbits and with PGA threads in 22 of 34.

摘要

在68只兔子身上，股骨内侧髁截骨术分别用液态正丁基 - 2 - 氰基丙烯酸酯、骨水泥和可生物降解的聚乙醇酸（PGA）线，或仅用PGA线进行固定。随访时间分别为1、3、6、12、24和48周。进行了宏观、放射学、组织学、显微放射学和土霉素标记研究。显微镜下，34只兔子中，用组合材料固定的内侧髁有8只愈合，用PGA线固定的有22只愈合。
