摘要(Abstract)：
[目的]发展一种膝关节术中直接测量股骨后髁角的新方法,并分析股骨后髁角与股骨髁外翻角、胫骨平台内翻角、股胫角的相关性,探讨各角度在膝关节置换术中的意义。[方法]研制股骨后髁角测定仪。对29例(30膝)在本院行人工膝关节置换术的骨关节炎患者,术前测量患膝负重前后位X线片上股骨髁外翻角、胫骨平台内翻角、股胫角,术中用股骨后髁角测定仪测量后髁角;分析股骨后髁角与股骨髁外翻角、胫骨平台内翻角、股胫角的相关关系。[结果]该组股骨后髁角为5.2°±2.6°,股骨髁外翻角为8.6°±2.9°,胫骨平台内翻角为4.1°±4.0°,股胫角为4.1°±7.3°,股骨后髁角和股骨髁外翻角、胫骨平台内翻角之间存在正相关关系,和股胫角无相关关系。[结论]股骨后髁角测定仪提供了术中测量股骨后髁角的新方法,为股骨假体旋转对线提供依据;股骨后髁角和股骨髁外翻角、胫骨平台内翻角之间存在正相关关系,术前测量股骨髁外翻角和胫骨平台内翻角,可为股骨假体旋转角度提供参考。
