腕舟骨的X线形态与损伤部位对照研究

The Comparative Study of Radiographic Pattern and the Position of Trauma Os Navicular in Wrist

目的：通过分析、对照舟骨骨折部位和健侧舟骨的X线形态，探讨舟骨损伤中形态与骨折部位的规律。材料与方法：对100例舟骨骨折部位和患者对侧正常舟骨的X线形态进行对照研究。结果：腰部骨折82例，远端骨折10例，近端骨折8例。舟骨形态：细长型82例，粗短型11冽，不规则型7例。结论：细长型舟骨损伤后易发生骨折，而且常在腰部，粗短型舟骨很少骨折，如发生骨折多在远端和结节部，不规则型舟骨虽不易骨折，但常发生旋转不良，骨折时易合并腕骨多发性损伤。

Purpose: In this artic1e, we analysed the radiographic pattern and the position of fracture with opposite side, discussed the law of pattern and the sites of fracture. Materials and Methods: We compared the radiographic patterns with opposite side ofone hundred cases of os navicular fractures for this study. Resuits: In this series were classified wrist fracture 82 cases, distal end fracture 1 cases, proximal end fracture 8 cases. The pattern of os navicular: long and thin type 82 cases, short and thick type 11 cases,irregular type 7 cases. Conclusion: After trauma, long and thin type were easily fractured in wrist, short and thin type fractured invery few cases, and always at the distal end and at the tuberosity in irregular type always with malrotation were not fracture, if fractureoccured, may complicated with multiple trauma of wrist.
