摘　　要：目的分析测量不同AO分型的桡骨远端骨折病例腕部正位X线片的腕关节新的形态学参数数值，判断骨折后这些参数变化范围及相互关系，指导临床治疗。方法本文采用标准x线摄片技术，利用Pacs系统软件测量83例桡骨远端骨折患者腕部正位x线片的11个影像学参数，其中包括7个新的影像学参数：尺骨茎突长度（ulnar styloid length，USL）、尺骨小头长度（ulnar head length，UHL）、尺骨小头直径（ulnar head diameter，UHD）、桡骨远端最大宽度（maximal distal radius width，MDRW）、桡骨远端近侧宽度（proximal distal radius width，PDRW）、乙状切迹长度（sigmoid notch length，SNL）、乙状切迹宽度（sigmoid notch width，SNW），同时这些参数与第三掌骨长度比值定义为相应指数。采用统计学方法分析各组间差异及各组与正常值间的差异，并分析各参数间相关性。结果对不同AO型患者测量的11个参数及其对应指数统计分析发现，其中有27对指数之间有明显差异，14组指数与正常值有明显差异，各组参数中共有62对参数间存在相关性。结论本文所测量AO不同分型桡骨远端骨折患者新的X线正位片参数，有助于判断各型桡骨远端骨折损伤程度，并有利于细化桡骨端骨折的诊疗。Objective To provide the basic knowledge of wrist joint for diagnosing of these morphological change in pathological condition by measuring the posteroanterior X-ray films of different types of distal radius fracture by AO classification. Methods Eleven radiographic indexes were measured including following 7 new parameters of 83 cases of distal radius fracture： ulnar styloid length （USL）, ulnar head length （UHL）, ulnar head diameter （UHD）, maximal distal radius width （MDRW） , proximal distal radius width （PDRW）, sigmoid notch length （SNL） and sigmoid notch width （SNW） by Pacs system in standard X-ray films. The indexes were defined by the ratio of these parameters to the length of the third metacarpal. Statistical significance of indexes and correlations of parameters were analyzed by SPSS 16. 0. Results It was found that indexes of 11 parameters and 27 pairs of indexes had significantly different. Compared the indexes of 14 groups with normal group existed statistical significance, 62 pairs value of 11 parameters had correlations. Conclusion The study provides additional radiographic index that will be helpful to more careful diagnosis and treatment of the distal radius fractures and their associated injuries such as ulnar wrist injuries or carpal instability.
