KÖHLER'S DISEASE OF THE TARSAL SCAPHOID OR OS NAVICULARE PEDIS RETARDATUM

Abstract

There are two distinct pathologic entities to which the name of Kohler's disease has been given. One of these occurs in the head of the second metatarsal, and the other in the scaphoid of the tarsus. A similar condition has been described by Kienbock as occurring in the carpus. In this paper, we shall deal only with the condition as seen in the tarsal scaphoid. We suggest as an accurate descriptive name the term os naviculare pedis retardatum. To correspond with this term, we suggest for the other two conditions the names metatarsus planus and os lunatum retardatum. We are presenting this paper because we recently had an opportunity to study a typical case of os naviculare pedis retardatum from both the clinical and the pathologic points of view.
