Abstract
Ative ulnar variance and Kienbock's disease. Blacks have more positive ulnar variance and the disease is less likely to develop in them than in whites. The distal extent of the radius and ulna (ulnar variance) was compared on roentgenograms of normal wrists in randomly selected black and white patients and of fifteen affected wrists in patients with Kienbock's disease. The results establish a statistically significant association between negative ulnar variance and Kienbock's disease. Blacks have more positive ulnar variance and the disease is less likely to develop in them than in whites. Copyright © 1975 by The Journal of Bone and Joint Surgery, Incorporated...
