ANATOMICAL FEATURES OF OS LUNATUM: SIGNIFICANCE IN THE WRIST JOINT STATICS AND MECHANICS

D. Kamburov, G. Marinov, S. Dyankova

Abstract

Os lunatum cannot resist this pressure which is considered to be one of the reasons for the development of Kienbock s disease. This resistance to the considerable pressure depends on some morphological features of the wrist bones and ofOs lunatum in particular. The variations of the anatomical features were studied on 12 cadaver wrists. The results showed that Os lunatum could contact the bones of the distal wrist row and those of the forearm in different ways: i) with Os capitatum and with two separated articular surfaces for radius and discus articularis - in 33,33 % and ii) Os capitatum, Os hamatum and with two separated articular surfaces for radius and discus articularis - in 66,67 %.


Keywords
