Ulnocarpal impaction syndrome was diagnosed in six wrists of five patients with neutral or negative ulnar variance. All underwent ulnar shortening with satisfactory results. The average grip strength increased from 53% to 78% and the range of flexion-extension increased from 82% to 93%, the mean Cooney's score improved from 25 to 83. These cases show that ulnocarpal impaction syndrome can occur in wrists with zero or negative ulnar variance, and that ulnar shortening is an effective treatment for such wrists.
在5例尺骨变异为中性或阴性的患者的6个腕关节中诊断出尺腕撞击综合征。所有患者均接受了尺骨短缩术，结果令人满意。平均握力从53%提高到78%，屈伸范围从82%增加到93%，Cooney平均评分从25分提高到83分。这些病例表明，尺腕撞击综合征可发生于尺骨变异为零或阴性的腕关节，尺骨短缩术是治疗此类腕关节的有效方法。
