Displaced intra-articular distal radius fractures are difficult to treat, with numerous associated complications. The potential onset of post-traumatic osteoarthritis (OA) is a major concern. The relationship between malreduced intra-articular fracture of the distal radius and subsequent early onset of radiocarpal OA is clinically important, yet poorly understood. To better understand this pres...

15 Introduction 16 The application of radiofrequency energy (RFE) has become widespread for 17 surgical performed chondroplasty especially due to the estimated sealing 18 effect. But safety for procedures in the wrist remains obscure. The purpose of 19 this study was to investigate the subchondral temperature during 20 radiofrequency energy (RFE) application simulating chondroplasty in an 21 ar...

BACKGROUND The goal of this study was to compare simple radiographic findings and clinical results according to residual ulnar variance following ulnar shortening for ulnar impaction syndrome. METHODS Forty-five cases of ulnar impaction syndrome, which were treated with ulnar shortening from 2005 to 2008, were studied retrospectively. Group I included 13 cases with positive residual variance ...

Six recessive lethal mutants of Anopheles albimanus are described. Homozygotes for three of the autosomal mutants, viz., bar eye, dot eye and hairy, die during the last larval or early pupal stages; complete linkage data are lacking for bar eye and hairy but dot eye is tightly linked to red eye on the right arm of chromosome 2. Larval and pupal mortality is high for homozygotes of the other two...

Kienböck's disease, defined as avascular necrosis of the lunate, is a relatively rare condition with a poorly understood etiology. Conservative and invasive treatments for Kienböck's disease exist, including wrist immobilization, surgical joint-leveling procedures, vascularized bone grafting, proximal row carpectomy, and total wrist arthrodesis. Staging Kienböck's disease using radiography assu...

Background Treating chronic scapholunate ligament injuries without the presence of arthritis remains an unsolved clinical problem facing wrist surgeons. This article highlights a technique for reconstructing the scapholunate ligament using novel fixation, the ScaphoLunate Axis Method (SLAM). Materials and Methods In a preliminary review of the early experience of this technique, 13 patients wer...

Avascular necrosis of the lunate bone (Kienböck disease) is caused by loss of blood supply of the bone. This study aimed to evaluate the efficacy and safety of a novel nickel-titanium (Ni-Ti) memory alloy arthrodesis concentrator in the treatment of this disease.A consecutive 24 patients with stage IIIb aseptic lunate necrosis were treated with scapho-trapezio-trapezoeid (STT) arthrodesis using...

condylar dislocation is not an uncommon condition and occurs when the condyles are displaced anterior to the articular eminence and are unable to reduce back into the glenoid fossa. long-standing dislocations are difficult to treat with the conservative methods and usually need surgical intervention. in this paper, a long-standing dislocation treated by bilateral extra-oral ramus osteotomy is d...
