摘　　要：目的探讨腕关节侧位三角形阴影的改变对腕骨脱位的诊断价值。方法68例腕骨脱位患者均摄有腕关节正侧位片，通过对腕关节正常影像学表现及腕骨脱位的影像学资料进行观察分析，对比腕骨脱位患者腕关节侧位三角形阴影的改变。结果68例腕骨脱位患者中，腕关节侧位三角形阴影有改变65例，占95．59％，无改变3例，占4．41％。其中单纯腕骨脱位17例，腕关节侧位三角形阴影有改变15例，无改变2例；腕骨周围脱位32例，腕关节侧位三角形阴影有改变31例，无改变1例；经腕骨腕骨脱位或腕骨周围脱位19例，腕关节侧位三角形阴影均发生改变。结论腕关节侧位三角形阴影的改变对绝大多数腕骨脱位的诊断有重要价值，对腕骨侧向脱位的诊断无意义。Objective To investigate the diagnostic value of triangular shadow changes in carpus dislocation. Methods 68 patients with carpal dislocation underwent frontal and lateral X-ray films. The changes of triangular shadow on lateral films were evaluated based on imaging findings of normal wrist ioints.Results Changes of triangular shadow were found in 65 （95.590/00） patients, while 3 （4.41%） patients had no changes. There were 17 patients with simple carpal dislocation, in which 15 cases showed triangular shadow changes, while 2 patients showed no changes. Thirty-two patients got pericarpal dislocation,in which 31 cases with triangular shadow changes and 1 case without any changes. The triangular shadow changes were observed in all 19 patients with trans-carpal carpal dislocation or trans-carpal pericarpal dislocation. Conclusion The changes of triangular shadow are helpful in the diagnosis of carpal dislocation, it is difficult to diagnose carpal lateral dislocation.
