背景：游离性尺桡关节远端掌脱位是一种罕见的损伤。这很容易导致误诊。既往文献报道均为旋转暴力。我们报告了一个直接撞击性暴力的病人。我们报告一位31岁男性劳工因急性创伤来到我院。右手腕严重压痛，活动受限。接受x线片检查，诊断为孤立性尺桡关节远端掌脱位。治疗方法为闭合复位夹板固定。半年后，患者先前疼痛的手腕功能恢复。结论据我们所知，这是第一例由直接冲击暴力引起的远端尺桡关节孤立性掌脱位。患者和医生应该意识到这种损伤机制的特性，以便能够实现早期诊断和治疗。
BackgroundIsolated palmar dislocation of distal radioulnar joint is a rare injury. It can easily lead to misdiagnosis. Previous literature reports were all rotation violence. We reported a patient with direct impact violence.Case presentationWe report a 31-year-old male laborer presented to our hospital with an acute trauma. Severe tenderness and limited mobility were seen in his right wrist. He received an x-ray film examination and diagnosed as the isolated palmar dislocation of distal radioulnar joint. The treatment was closed reduction and splint fixation. After half a year, the patient gained a functional recovery of his previously afflicted wrist.ConclusionsTo the best of our knowledge, this is the first case of isolated palmar dislocation of distal radioulnar joint caused by a direct impact violence. Patients and physicians should be aware of the properties of this mechanism of injury so that early diagnosis and treatment can be achieved.
