Abstract
The operative results of radial shortening in 23 patients with Kienböck’s disease were analysed on the basis of age, stage of disease, ulnar variance and the amount of radial shortening. The patient’s age was found to be the factor which affected the operative result most and unsatisfactory results were obtained in patients over 30 years old. However, neither the clinical stage nor ulnar variance affected the results significantly and the results in patients with ulnar zero or plus were no worse than in patients with ulnar minus. The risk of ulnar wrist pain was increased when the radius was shortened more than 4 mm in patients with positive or zero ulnar variance. This was an important cause of unsatisfactory operative results.
