In most murine fracture models, the femur is stabilized by an intramedullary implant and heals predominantly through endochondral ossification. The aim of the present study was to establish a mouse model in which fractures heal intra-membraneously. Femur fractures of 16 SKH-mice were stabilized by an internal locking plate. Femur fractures of another 16 animals were stabilized by an intramedull...

The locking compression plate fixation treatment for the unstable sacral fractures is simple and effective, with less trauma and complications. Some locking compression plate parts have been made of high-strength Plate manufactured by hot stamping process since the demand for lightweight biomedical materials. Finite Element (FE) method of One-Step inverse forming based on deformation theory is ...

OBJECTIVE To compare the mechanical stability of a fixed-angle blade plate with that of a locking plate in a cadaveric proximal humerus fracture-fixation model subjected to cyclic loading. A secondary objective was to evaluate whether the use of synthetic humerus specimens would replicate significant differences found during cadaveric tests. DESIGN Mechanical evaluation of constructs in bendi...

Paper focuses on biomechanics, specifically on locking cortical bone screws in angularly stable plates used for the treatment of bone fractures in the medical fields of traumatology and orthopaedics. During extraction of titanium-alloy implants, problems are encountered in an effort to loosen some locking bone screws from the locking holes of an angularly stable plate and the subsequent strippi...

BACKGROUND Plate on plate technique can lessen operative time and patient morbidity. OBJECTIVES This study aimed to evaluate the outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) using plate on plate technique of locking plate fixation for closed fractures of distal tibia in a prospective study. PATIENTS AND METHODS Twenty-five patients with distal tibial fractures we...

BACKGROUND There are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. In the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. METHODS Forty patients with valgus knee malalignment were randomly assigned to two equal numb...

INTRODUCTION The aim of this study was to examine resistance to angulation and displacement of the internal fixation of a proximal first metatarsal lateral displacement osteotomy, using a locking plate system compared with a conventional crossed screw fixation. MATERIALS AND METHODOLOGY Seven anatomical human specimens were tested. Each specimen was tested with a locking screw plate as well a...

OBJECTIVE To compare the biomechanical stability of extraarticular proximal tibia fractures reconstructed using a double-plate construct, locking plate system, hybrid external fixator, and single lateral periarticular plate, all from the same manufacturer. DESIGN Standardized proximal tibial fractures (AO classification 41-A3.2 and A3.3) in synthetic tibiae were stabilized using one of the fo...

INTRODUCTION: Stability of the proximal humeral fracture can be difficult to achieved if osteoporosis or severe loss of bone stock is presented. Recently, locking plate technology has included these fractures, but appears that may not be predictable as hoped. Recent studies have demonstrated the importance of both reduction and mechanical support of the medial column in proximal humerus fractur...

BACKGROUND Open reduction and internal fixation using an interlocking plate system has gained popularity for the treatment of dorsally displaced distal radius fractures. PURPOSE To evaluate the functional and radiological results of treating unstable distal radius fractures with the volar locking plate. PATIENTS AND METHODS A retrospective review was conducted of patients from one instituti...
