Radioulnar synostosis
Medical condition / From Wikipedia, the free encyclopedia
Radioulnar synostosis is a rare condition where there is an abnormal connection between the radius and ulna bones of the forearm.[1] This can be present at birth (congenital), when it is a result of a failure of the bones to form separately, or following an injury (post-traumatic).[2]
