摘　　要：目的：探讨MRI在桡骨头骨折合并前臂骨间膜损伤中的诊断价值。方法：收集2011年12月至2012年12月间所有桡骨头骨折患者26例，其中男15例，女11例；年龄21～53岁，平均37.6岁。所有患者于伤后72 h内就诊，伤后1周内行伤侧尺桡骨全长X线片、伤侧CT（必要时加三维重建）及MRI检查（包括肘及腕关节）.观察前臂骨间膜在磁共振上的表现（有无损伤、损伤的部位及损伤的程度），桡骨头骨折的损伤程度，比较两者的相关性。结果：桡骨头骨折Mason Ⅰ-Ⅲ型均可伴有前臂骨间膜损伤，桡骨头骨折程度与前臂骨间膜损伤程度成正相关（P〈0.05）.结论：桡骨头骨折伴前臂骨间膜可疑损伤时，有必要进行前臂MRI检查，明确骨间膜有无损伤及损伤程度，根据骨间膜损伤的情况对桡骨小头骨折选择正确的治疗方法，只有这样才能有利于肘关节和前臂功能的恢复。Objective： To investigate the diagnostic value of MRI in radial head fracture with forearm interosseous membrane injuries. Methods： From December 2011 to December 2012,26 patients with fractures of capitulum radial in our hospital were collected. There were 15 males and 11 females,ranging in age from 21 to 53 years old,with an average of 37.6 years old. All the patients visited hospital within 72 hours after injuries. X-ray radiography of full ulnar radial length in injured side,CT in injured side（three-dimensional reconstruction if necessary） and MRI（including the elbow and wrist joints） were performed within a week after the injury. The MRI manifestations of the forearm interosseous membrane（with or without damage,the injured location and the injury degree） and the fractures degree of radial head were observed and compared for the relativity. Results： Radial head fracture from Mason typeⅠto Ⅲ was associated with the forearm interosseous membrane injury. Radial head fracture degree was positive correlated with forearm interosseous membrane injury degree（P〈0.05）. Conclusion： Radial head fracture with suspicious forearm interosseous membrane injury is necessary to take MRI for checking for any interosseous membrane injury and injury degree,then choose the right treatment for radial capitulum fracture,only in this way can be helpful for the functional recovery of elbow and forearm.
