RESUMO
Radiocarpal dislocation is an extremely uncommon injury in Traumatology, and is usually produced by high energy trauma. There are two types of dislocation, type I: pure radiocarpal dislocation and type II: fracture-dislocation. The gold standard treatment according to the literature is surgical treatment fixing the fractures and repairing the injured ligaments. We report a clinical case of radiocarpal dislocation type I in a healthy 19 year-old male after a minor trauma. The dislocation was reduced by traction, and the wrist immobilized in a plaster cast. The functional outcome 12 months after the injury was excellent.

El fenómeno de Raynaud es un proceso vasoespástico que afecta típicamente a las partes acras de las extremidades en respuesta al frío o a estímulos mecánicos o emocionales. Este fenómeno se clasifica como primario cuando no se evidencia una causa subyacente, y secundario cuando existe una entidad patológica asociada. Esta distinción es importante pues condiciona el pronóstico, la gravedad y el tratamiento. Fisiológicamente, el equilibrio vasomotor se mantiene por complejas interacciones entre el endotelio, músculo liso y el sistema nervio autónomo que inerva los vasos. En esta revisión se analizan los mecanismos implicados en su desregulación, así como las diversas aproximaciones terapéuticas de acuerdo con la evidencia médica más reciente (AU)
Raynaud´s phenomenon is a vasospactic process that typically affects the acral parts of the limbs in response to cold or emotional or mechanical stimuli. This phenomenon is classified as primary when no evidence of an underlying cause, and secondary when there is an associated pathological entity. This distinction is important because it determines the prognosis, severity and treatment. Physiologically, the vasomotor balance is maintained by complex interactions between endothelium, smooth muscle and autonomic nervous system innervates the vessels. This review discusses the mechanisms involved in deregulation, and the various therapeutic approaches according the latest medical evidence (AU)
