Ulnocarpal impingement can be surgically managed with various shortening osteotomy techniques. The purpose of this study was to retrospectively examine the outcomes of the ulnar-shortening osteotomy technique using the Trimed dynamic compression plate (Valencia, California) and to determine whether results vary among patient-related factors, including smoking status, occupation, preoperative di...

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 ...

The aim of this study was to determine the incidence of asymptomatic Kienböck's disease in patients who attended the Dr George Mukhari Hospital (formerly Ga-Rankuwa Hospital), as well as the relevance of ulnar variance on the disease. This was a retrospective study. In a 12 month period we reviewed postero-anterior radiographs of 1287 patients seen at our radiology department, with complaints u...

PURPOSE We report a series of 5 patients (mean age, 41 y) presenting with ulnar styloid impingement syndrome (USIS) and treated by an oblique ulnar styloid osteotomy. The purpose of the study was to determine whether the osteotomy is an effective method for treating USIS. METHODS The diagnosis of USIS was made based on a history of ulnar-sided wrist pain supported by clinical and radiological...

From September 1996 to September 1997, 27 adult patients were diagnosed with chronic triangular fibrocartilage complex (TFCC) tears with distal radioulna joint (DRUJ) instability in our clinic. They all received the procedure of TFCC reconstruction with partial extensor carpi ulnaris (ECU) tendon combined with or without ulnar shortening. There were 26 males and one female in the study with a m...

Alteration in length of the distal ulna may provide an attractive alternative to more destructive procedures commonly used for the treatment of mechanical and degenerative problems at the distal radioulnar joint. Ulnar recession has shown effectiveness in ulnolunate impingement, triangular fibrocartilage tears, and symptomatic ulnar plus variance. It has also been effective in chondromalacia of...

Hand and wrist radiographic indexes such as radial inclination, ulnar variance, carpal height ratio, and radial tilt play an important role in the diagnosis and management of medical disorders, so they should be modified regarding the population and race difference. This study aims to compare the normal radiologic wrist indexes in Mashhad population with other existing databases and define some...
