  • Title: Isolated palmar dislocation of distal radioulnar joint: a new mechanism of injury: a case report.
    Author: Lin X, Shen H, Lu H.
    Journal: BMC Musculoskelet Disord; 2019 Aug 09; 20(1):368. PubMed ID: 31399084.
    Abstract:
    BACKGROUND: Isolated 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 PRESENTATION: We 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. CONCLUSIONS: To 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.
