The initial radiographs of 42 split-compression fractures of the lateral tibial condyle were studied. The breadth of the wedge-shaped fragments, measured at the level of the articular surface, was found to decrease with increasing severity of osteoporosis. Ranks were assigned to the breadths and average ranks to the grades (low ranks for normals). Spearman's rank correlation co-efficient was -0.507, which is significant at the 1% level. The length of the fragments showed a similar decrease with advancing bone loss. Rank correlation with the degree of osteoporosis was -0.393, which is significant at the 5% level. These results support the hypothesis that the fracture pattern depends on the changes in bony architecture which results from osteoporosis.
对42例外侧胫骨髁部劈裂压缩性骨折的初始X线片进行了研究。在关节面水平测量的楔形骨折块宽度，发现随着骨质疏松严重程度的增加而减小。对骨折块宽度进行了排序，并对骨质疏松等级赋予平均秩次（正常者秩次低）。Spearman秩相关系数为-0.507，在1%水平具有显著性。随着骨质流失的进展，骨折块长度呈现类似的减小。与骨质疏松程度的秩相关为-0.393，在5%水平具有显著性。这些结果支持了骨折类型取决于骨质疏松导致的骨结构变化这一假说。
