This study compared the biomechanical properties of bone-stapling techniques with those other fixation methods used for stabilizing tibial tuberosity fractures using 3-dimensionally (3D)-printed canine bone models. Twenty-eight 3D-printed models made from computed tomography scan files were used. Tibial simulated osteotomy. All samples divided into 4 groups. Group 1 was stabilized a pin and ten...

BACKGROUND Implant-related osteomyelitis is a major complication that requires immediate treatment, often involving removal of the implant, prolonging patient recovery and inflating expenses. Current research involving interventions to diminish the prevalence of such measures include investigating prophylactic and therapeutic remedies. A proper and accurate animal model is needed to thoroughly ...

For revision knee surgery with uncontained tibial bone defects, the authors report the containment of compacted morsellized allograft using metal-wire mesh, followed by implantation of a cemented total knee prosthesis. This method is comparable to the "impaction grafting technique" described for revision hip surgery and could be an alternative to metal wedges, augmented components, custom-made ...

For the reconstruction of extensive craniofacial bony defects, autogenous bone is the material of choice because of its potential for revascularization and its osteoconductive and osteoinductive properties. In the present study, the results obtained after grafting with autogenous bone grafts in 233 patients with facial bony defects are analyzed retrospectively. At the Department of Maxillo-Faci...

Open segmental fractures of both bones of the forearm with the loss of the middle segment of the radius is a rare injury in children. An eight-year-old boy presented to our clinic four days following a road traffic accident. The child's mother was carrying a 12-cm long extruded and soiled segment of the radius bone. The extruded bone segment seemed necrotic, and we decided not to use it for rep...

Orthopedic wires and pins are regularly used for the treatment of dislocations and bone fractures. Migration of these metallic fixation devices into the spinal canal is an uncommon complication. We present a 35-year-old man who underwent thoracic spinal canal migration of a Kirschner wire. The patient had undergone treatment of acromioclavicular joint dislocation with Kirschner wire fixation. T...

An acidic microenvironment formed by vacuolar ATPase (V-ATPase) expressed in plasma membranes of osteoclasts is thought to be indispensable for bone resorption. This study examined the efficacy of a novel V-ATPase inhibitor, FR202126, in reducing alveolar bone loss caused by experimental periodontitis in rats. FR202126 inhibited H+ transport in plasma membrane vesicles of murine osteoclasts, wh...

In some developing countries wire is still widely used in facial fractures internal fixation. This study presents the effectiveness and complications of wire osteosynthesis in a university teaching hospital in Burkina Faso and discusses some of its other benefits and disadvantages. Notes of 227 patients with facial fractures treated by wire internal fixation at department of stomatology and max...

Background. Minimally invasive intramedullary stabilization is a widely accepted method for treating long bone fractures in children. Indications concerning age and type of fracture have increased in the last decade. The aim of our study was to assess outcome in intramedullary Kirschner wire stabilization used to treat forearm fractures in children. Material and methods. From 1997 to 2004 intra...

Purpose We investigated two major factors which affect the overall accuracy of patient specific instrumentation (PSI) for cup insertion in total hip arthroplasty; 1) the fitting of PSI on the bony surface, and 2) deviation of cup impaction under a linear visual reference. Methods Using 12 cadaveric hips, we inserted Kirschner wire (K-wire) through PSI on the acetabulum for the linear reference ...
