Wrist injuries are an extremely common occurrence. The origin of these injuries may be due to a fracture of the two bones of the forearm or the wrist bones, which may sometimes require specific X-rays views. They are rarely responsible for a dislocation of the wrist. Strains wrists may be misdiagnosed and may result in instability of the wrist. The initial examination of all wrist injuries should systematically include the following four views: (1) a PAview of the wrist in pronation (with the palm facing downward). (2) a lateral view according to the Meyrueis technique. (3) an oblique view. (4) a scaphoid view. An additional, fifth view with the wrist in supination (with the palm facing upward) may be required. If there is clinical evidence of instability of the wrist or if the initial examination results in a probably strained wrist, a further more complete radiological examination can then be undertaken. This examination, known as "the instability examination" includes stress views, which can allow detection of a discrete instability of the wrist. Finally, it is sometimes necessary to carry out this examination in a bilateral and comparative manner.
腕部损伤极为常见。这些损伤的起因可能是前臂的两块骨头或腕骨骨折，有时可能需要特定的X光视图。它们很少导致腕关节脱位。腕部扭伤可能会被误诊，进而导致腕关节不稳定。对所有腕部损伤的初步检查应系统地包括以下四个视图：（1）腕关节旋前位的正位片（手掌向下）。（2）根据梅吕埃斯技术拍摄的侧位片。（3）斜位片。（4）舟状骨位片。可能还需要额外拍摄一张腕关节旋后位（手掌向上）的第五张视图。如果有腕关节不稳定的临床证据，或者初步检查结果显示可能是腕部扭伤，那么可以进行更全面的放射学检查。这种检查被称为“不稳定检查”，包括应力位片，可检测出腕关节的细微不稳定。最后，有时有必要以双侧对比的方式进行这项检查。
