Bilateral Kienböck’s disease with bilateral negative ulnar variance: a case report

Abstract

Purpose: Kienböck’s disease usually occurs unilaterally on dominant hands. As such, bilateral avascular necrosis of the lunate, in concurrence with bilateral negative ulnar variance (NUV), is a very rarely described condition.
 Case report: The case of a patient diagnosed with bilateral avascular necrosis of the lunate is presented. Plain film and magnetic resonance imaging confirmed bilateral NUV was also present.
 Conclusions: Although the relationship between Kienböck’s disease and NUV remains unclear, the bilateral concurrent appearance of both might instigate a discussion of the possible etiology of avascular lunate necrosis.
