The pathophysiologic mechanism of osteoarthritis is not well known. The importance of reactive oxygen species and nitric oxide in the pathogenesis of osteoarthritis in patients with chondral or meniscal lesions or both and a search for their source were investigated. Synovial fluid samples obtained from 44 patients with osteoarthritis (16 had meniscal(More)
The present study was designed to demonstrate the efficacy of standard 4.0 mm cannulated screw fixation by comparing it with palmar locking plate fixation in the treatment of acute, unstable, simple extra-articular distal radius fractures. We prospectively collected and retrospectively analyzed outcomes data for 65 patients aged between 18 and 60 with AO(More)
PURPOSE To evaluate the incidence and types of capitellar cartilage injuries associated with higher-grade radial head fractures. METHODS Fifty-one consecutive patients with operatively treated, unstable, displaced Mason type II to III radial head fractures were identified. Ten of 51 patients had capitellar cartilage injuries concomitant with these(More)
Conductivity is a non-linear function of electrolyte concentration in solutions and could be used as an indirect method. The aim of this study was to determine the feasibility of urine conductivity measurement, which is a simple, cheap and not time consuming method, in the evaluation of renal functions. Seventy-two patients whose primary diseases were not(More)
The aim of this study was to determine the results of closed reduction and percutaneous fixation of distal radial fractures with standard 4.0-mm cannulated screw. We collected prospective outcomes data for 20 patients between 18 and 60 years of age (mean 39) with acute, displaced, extraarticular and unstable fractures of the distal radius treated with(More)
The purpose of this retrospective study was to compare the clinical results of three different fixation techniques for the treatment of Neer Type IIb fractures. We hypothesized that anatomic locking plate and coracoclavicular stabilization with suture endo-button technique provides more stable and biomechanically superior fixation among others with low(More)
The purpose of this study is to determine the immediate effects of pH change on the metabolism of bovine chondrocytes. Bovine osteochondral explants were pre-cultured and placed in Ringer’s lactate solution. Thirty explants were randomly divided into 3 groups. Buffered Ringer’s lactate, pH 7.2, was used in Group I; buffered Ringer’s lactate, pH 7.4 (normal(More)
This retrospective study was designed to define the technical details for the treatment for distal tibial fractures with intramedullary nails and blocking screws, and to assess the effectiveness of the method based on our clinical practice. Twenty-one patients in whom adequate reduction could not be achieved with distal tibial intramedullary nailing,(More)
Screws with different levels of compression force are available for scaphoid fixation and it is known that the Acutrak screw generates greater compression than the Herbert screw. We retrospectively compared two types of headless compression screw for their effectiveness in the repair of scaphoid nonunion. Twenty-nine cases of proximal scaphoid nonunion were(More)
