【摘要】 目的：为胫骨下段骨折内固定塑形钢板提供解剖学基础。方法：对国人胫骨８１副（男４１副，女４０副）进行下段扭转角及外翻角测量。结果：①胫骨下段扭转角，男性左侧６４．８°±３．６°，右侧６８．７°±２．８°，女性左侧６３．６°±５．１°，右侧６７．０°±６．１°。②胫骨下段外翻角：男性左侧１５．６°±３．０°，右侧１４．２°±２．１°，女性左侧１５．６°±３．０°，右侧１６．４°±２．９°。结论：男性无论扭转角还是外翻角其侧别差异显著Ｐ＜０．０１及Ｐ＜０．０５；女性扭转角侧别差异显著Ｐ＜０．０１而外翻角侧别无差异Ｐ＞０．０５；除右外翻角性别间差异显著Ｐ＜０．０１外，其余各角性别间均无差异Ｐ＞０．０５。这为临床实践提供了新资料。在此基础上研制的内固定钢板更能符合胫骨下段的解剖特点，避免或减少因钢板塑形不佳所带来的并发症。更多还原

【Abstract】 Objective:To provide anatomy data for molding steel plate of internal fixation applied in the fracture of the lower tibial.Methods:The twist angle and eversion angle were measured on 81 sets(male 41 and female 40)of tibiae.Results:The twist angles of lower tibial were 64.8°±3.6° on left and 68.7°±2.8° on right for male,63.6°±5.1° on left and 67.0°±6.0° on right for female.The corresponding eversion angles were 15.6°±3.0°,14.2°±2.1°,15.6°±3.0° and 16.4°±2.9° respectively.Conclusions:There was significant difference between sides except the female eversion angle,while no sexual difference was found except the right eversion angle.The molding steel plate designed based on these data should be accord with the natural feature of the lower tibia better.更多还原
