摘要(Abstract):
<正> 股骨粗隆间骨折治疗方法有很多种,但无论非手术治疗还是手术治疗都存在着卧床时间长,并发症多等问题。八十年代末期,国外开始使用Gamma钉治疗股骨粗隆间骨折,经不断改进,应用日益广泛。临床和生物力学研究表明,Gamma钉是治疗股骨粗隆间骨折较为理想的方法。我所自1993年来在国外原钉基础上对该钉大小,形状以及瞄准装置加以改进,形成了改良型Gamma钉,并成功应用于临床。本研究旨在对改良型Gamma钉(GN)和以前应用较多的国产麦氏鹅头钉(MNP),经矩4枚斯氏针(MSP)进行生物力学比较分析。1 材料与方法1.1 实验标本 防腐尸体股骨4对,取自福尔马林固定的解剖尸体,用来作Gamma钉和经矩4枚斯氏针的生物力学比较分析。
