Kienbock Disease; the Length of Capitate and Third Metacarpal Bones

Abstract

Background: The relationship between negative ulnar variance and Kienböck's disease is unknown and does not justify all of the cases. The present study planed the hypothesis that maybe the pressure from distal structures to the lunate bone plays a role in the etiology.

The Role of Lunate Morphology in the Severity of Kienböck Disease: A Retrospective Study

“…Despite the identification of the disease entity over 100 years ago, the etiopathogenesis of Kienböck disease is still uncertain. Even so, it has been associated with a variety of predisposing factors including single trauma, repetitive microtrauma, damage to the lunate blood supply, corticosteroid use, negative ulnar variance, decreased radial inclination, and lunate morphology [3][4][5]. Viegas et al classified the lunate morphology based on the absence (type I) or presence (type II) of hamate facet at least 2 mm.…”
