尺、桡骨远端解剖变异与月骨缺血性坏死关系的研究

An investigation on the relationship between negative ulnar variance, radial inclination and the occurence of Kienbock's disease

目的:了解月骨缺血坏死关节的尺骨负变异率、桡骨远端关节面尺偏角与正常人关节是否有明显的不同。方法:在年龄、性别、手别匹配以及投照体位标准化的条件下,对28例月骨缺血性坏死的31侧患腕、31侧正常人腕关节正位X线平片进行对比观测,另外还观测了25例单侧发病患者患、健腕的正位X线平片。结果:无论是尺骨负变异率还是桡骨远端关节面尺偏角,患腕与正常腕、患腕与健腕之间均无显著性差异(P>0.05)。结论:尺骨负变异、桡骨远端关节面尺偏角的大小与月骨缺血性坏死的发生似乎没有关联。

Objective: X-ray films of wrists were studied to consider the relationship of ulnar variance and radial inclination to Kienbock's disease. Methods: P-A view X-ray films of 31 wrists with Kienbock's disease in 28 patients were compared with those of 31 normal wrists in an age/sex/limb-matched way. In anothor 25 patients of Kienbock's disease, the X-ray films of the affected wrist were compared with those of the contralateral unaffected side. Ulnar variance and radial inclination were measured by standardized means. Results: As far as negative ulnar variance and radial inclination were concerned, no significant difference was found between either the affected wrists and the normal ones, or the affected wrists and the contralateral unaffected wrists from patients with Kienbock's disease (P>0.05). Concluslon: Based on our results, it seems that these anatomic variahces are not important in etiology of Kienbock's dis
