The Influence of Age and Sex on Ulnar VarianceFrom the Department of Orthopaedic Surgery (Division of Hand Surgery), Nagoya University School of Medicine, Japan Correspondence: Ryogo Nakamura, M.D., Department of Orthopaedic Surgery, Branch Hospital of Nagoya University School of Medicine, 1-1-20 Daikominami, Higashi-ku, Nagoya 461, Japan. Ulnar variance was measured in 325 normal wrists and 41 wrists with Kienböcks disease. A positive correlation between ulnar variance and age was confirmed in normal wrists, and it was lower in males than in females. Therefore, studies comparing ulnar variance in abnormal and normal wrists require carefully selected age- and sex-matched controls. There was no significant difference in ulnar variance between Japanese with normal wrists and those affected by Kienböcks disease, when the effects of sex and age were taken into account. Based on these results, we believe that ulnar variance is highly unlikely to be an important predisposing factor in Kienböcks disease.
