Quizplus · Accepted Answer

Keinbock's disease is a condition in which the blood supply to one of the small bones in the wrist (lunate bone) is disrupted, leading to its death (avascular necrosis). It has been suggested that negative ulnar variance (when the ulna bone is shorter than the radius bone) is a risk factor for Keinbock's disease, although the relationship is not universally accepted in the literature. There is no known relationship between negative ulnar variance and Turner's syndrome, Leri Weill disease, or Down syndrome.
