The author presents two cases in which pseudoarthrosis of the ulnar diaphysis resulted in dislocation of the head of the radius. The pathogenesis of this secondary dislocation is discussed. The cause of anterior Monteggia fractures is not yet clear. Various explanations have been put forward: direct action of a force (Speed and Boyd, 1940), forced pronation (Evans, 1949) and hyperextension with strong contraction of the biceps (Wright, 1963). This work presents two cases of Monteggia fracture characterized by a "slow" fracture mechanism. The biomechanical aspects are discussed.
作者介绍了两例尺骨干假关节导致桡骨头脱位的病例。讨论了这种继发性脱位的发病机制。孟氏骨折前脱位的原因尚不清楚。已经提出了各种解释：暴力的直接作用（斯皮德和博伊德，1940年）、强迫旋前（埃文斯，1949年）以及肱二头肌强力收缩时的过伸（赖特，1963年）。本文介绍了两例具有“缓慢”骨折机制的孟氏骨折病例。并对其生物力学方面进行了讨论。
