Carpal malalignments in malunion of distal radius fracture are considered as an adaptive response of the carpus to loss of normal architecture of the distal radius. This condition leads to mechanical overload, ligament attenuation and progressive dynamic instability around the wrist joint. Radial corrective osteotomy is suggested as a treatment option of carpal malalignment after distal radius ...

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...

As an original technique developed by our department, the preliminary result of arthroscopic resection of volar wrist ganglion was first published in 2003. Since then, there were few reports in the literature concerning this new treatment method. The aim of the study is to evaluate the long-term outcome of this treatment technique. From August 1997 to April 2005, 21 volar wrist ganglia with ave...

We measured cartilage thickness, contact surface area, volume of the capitate and shape of the capitate during motion in the operated and unaffected wrists of 11 patients with a mean follow-up of 7.3 years after proximal row carpectomy. Radiocapitate cartilage thickness in the operated wrists did not differ significantly from radiolunate cartilage thickness in the unaffected wrists. The radiolu...

This article describes a case of a 24-year-old man with a total volar extrusion of the lunate and scaphoid proximal pole with concurrent scapholunate dissociation. The viability of the lunate and the proximal pole of the scaphoid are at high risk in this type of injury. Scaphoid nonunion, avascular necrosis of the lunate and proximal pole of the scaphoid, and carpal instability are inevitable u...

The patterns of laxity of normal wrists subjected to dorsal and volar stresses were analysed. Dorsal and volar displacement tests were carried out on both wrists of 50 subjects under image-intensifier control. Lateral projections in neutral, and dorsal and volar stress positions were taken to analyse the behaviour of the carpal bones. Varying degrees of capitolunate subluxation under dorsal and...
