Perched anteromedial radial head dislocation is a rare injury pattern that is yet to be reported in the literature. This article describes a case report of an isolated radial head dislocation that was perched on the coronoid process. The images in this study show this rare injury pattern, which did not include a fracture of the coronoid or true elbow dislocation. The patient was successfully treated with a closed reduction. The patient regained full ROM and function. Previously described literature has failed to report this injury pattern or successful closed treatment. The success of this case demonstrates the difficulty of closed reductions even under proper anesthesia and the importance of performing them in the setting where the surgeon has the option to convert to open reduction in unsuccessful cases.
桡骨头前内侧高位脱位是一种罕见的损伤类型，目前尚未见文献报道。本文描述了一例孤立性桡骨头脱位并高位位于冠状突上的病例报告。本研究中的影像显示了这种罕见的损伤类型，该损伤不包括冠状突骨折或真正的肘关节脱位。患者通过闭合复位成功治愈。患者恢复了完全的关节活动度和功能。既往文献未能报道这种损伤类型或成功的闭合治疗方法。该病例的成功表明，即使在适当麻醉下进行闭合复位也存在困难，并且在外科医生能够在复位失败时选择转为切开复位的情况下进行闭合复位非常重要。
