متن کاملRadiological investigation of relationship between lunate type and ulnar variance.
UNLABELLED Some variances and anatomical proportions of the wrist may contribute to development of avascular necrosis of the lunate. Kienböck's disease is more often encountered in young males, who suffer, among others, from type II of the lunate (with two joint surfaces for the capitate and hamate) and/or negative variance of ulna in relation to radius. The aim of the study was to investigate ...
متن کاملAvascular Necrosis of the Scaphoid Preiser Disease
No consensus regarding optimal treatment or etiology of Preiser disease exists. We described the epidemiology,classification and treatment characteristics of 18 patients with Preiser disease. Patients with changes related to previoustrauma, and without radiographs were excluded. Based on the radiographs at diagnosis, we classified 13 scaphoids asHerbert Lanzetta stage II, four...
متن کاملUlnar variance and the shape of the lunate bone. A radiological investigation.
The authors designed a study to test the hypothesis that the length of the ulna might affect the shape of the lunate bone because of long-term molding during life. This might then be useful to predict the presence or absence of a dynamic or static ulna plus by the shape of the lunate bone. In a prospective study, posterior-anterior wrist x-rays were taken in a standard fashion in 68 patients wi...
