Bone fractures and treatments

Surgical procedures concerning the distal articular surfaces of the radius and ulna, demand an accurate method of measurement of ulnar variance. A new method, which is a modification of the method described by Palmer (1982), is introduced. 100 randomly selected healthy persons were submitted to X-ray of the wrist and the ulnar variance was determined independently by three observers using both methods. By "weighted kappa" statistics the results, expressed in intra- and interobserver agreement, showed a significantly higher reliability in favour of the Modified method.
