Contralateral unaffected wrists from 41 males with Kienböck's disease were compared with wrists from 66 normal males. From X-rays, various features of the lunate and radius were measured. In patients with Kienböck's disease, the lunate tended to be smaller and inclined more radially than in normal subjects and the radial inclination was flatter. Discriminant analysis showed that 85% of the unaffected contralateral wrists in patients with Kienböck's disease and 74% of the wrists in normal subjects were accurately discriminated to their respective groups. It may be possible to identify subjects who are at risk for Kienböck's disease prior to onset using discriminant analysis.
将41例患有月骨无菌性坏死的男性患者对侧未受影响的手腕与66例正常男性的手腕进行比较。通过X射线测量月骨和桡骨的各种特征。与正常受试者相比，患有月骨无菌性坏死的患者，其月骨往往更小，向桡侧倾斜度更大，且桡侧倾斜更平缓。判别分析显示，85%患有月骨无菌性坏死患者的对侧未受影响手腕和74%正常受试者的手腕被准确判别到各自的组中。使用判别分析有可能在发病前识别出有患月骨无菌性坏死风险的受试者。
