Abstract

We herein report an unusual case of a fracture-dislocation of the thumb metacarpal base. The injury consisted of features typical of Bennett's fracture-dislocation of the thumb trapeziometacarpal joint, with additional rotation of the proximal fragment, signifying a greater ligamentous injury. Radiographic features of this injury are discussed together with its pathomechanics. Surgical management was undertaken due to the inherent instability of this injury.

摘要

我们在此报告一例罕见的拇指掌骨基底骨折脱位病例。该损伤具有拇指大多角掌关节Bennett骨折脱位的典型特征，近端骨折块伴有额外旋转，提示韧带损伤更严重。本文讨论了该损伤的影像学特征及其发病机制。由于该损伤固有的不稳定性，我们采取了手术治疗。
