A 30-year-old patient sustained the fracture in a motorcycle accident. A triplane-type of fracture of the distal femur was confirmed by CT scan. The trochlear fragment was reduced anatomically and was stabilized with 6.5mm cannulated screws. Once reconstruction of the coronal plane fracture was performed, the split lateral condylar fragment was fixed with a cannulated screw to the medial fragme...

BACKGROUND Percutaneous lag screw fixation is an alternative treatment for non-displaced or minimally displaced posterior column fractures. This study aims to explore new fluoroscopic views of the acetabulum for safe percutaneous insertion of posterior column lag screws. METHODS Axial computed tomography (CT) scans were taken of sixteen embalmed adult cadavers. The axial CT images at the leve...

BACKGROUND Volar locking plate fixation has become the gold standard in the treatment of unstable distal radius fractures. Juxta-articular screws should be placed as close as possible to the subchondral zone, in an optimized length to buttress the articular surface and address the contralateral cortical bone. On the other hand, intra-articular screw misplacements will promote osteoarthritis, wh...

Hoffa fracture is a rare injury consisting of unicondylar tangential posterior fracture of the distal femur and only very few cases have been reported in the literature. These fractures are due to high energy trauma and conservative treatment generally yields poor results, but rigid internal fixation allows early functional rehabilitation and decreases the incidence of complications. The purpos...

Introduction: The purpose of this study was to estimate the secondary cancer risk of thyroid for standard radiotherapy methods which are commonly used for breast cancer patients. Materials and Methods: Sixty-four breast cancer patients (their age range was around 50 years old) who referred to Seyed- Al- Shohada hospital (Isfahan, Iran) were included in this ...

The formation of a rich underground-seam network is the key problem in development low-permeability hot dry rock (HDR) resources. Considering lack macroscopic continuum theory to study hydraulic fracturing having preset fracture-interface element, particle-flow method micro-mechanical discrete-element introduced simulate mechanical behavior for HDR low permeability reservoirs. reservoir simulat...

background: providing a cross-sectional image is essential for preimplant assessments. computed tomography (ct) and cone beam ct (cbct) images are very expensive and provide high radiation dose. tangential projection is a very simple, available, and low-dose technique that can be used in the anterior portion of mandible. the purpose of this study was to evaluate the accuracy of tangential proje...

OBJECTIVES To compare the clinical and radiological outcomes after closed reduction (CR) and open reduction and internal fixation (ORIF) in the management of subcondylar fractures. MATERIALS AND METHODS Forty-eight patients presenting with subcondylar fracture between January 2010 and March 2013 were evaluated retrospectively. Fifteen patients were treated with CR and 33 patients with ORIF. T...

We consider a two-phase Darcy flow in fractured porous medium consisting matrix coupled with tangential the fractures, described as network of planar surfaces. This model is also mechanical deformation assuming that fractures are open and filled by fluids, well small deformations linear elastic constitutive law. The discretized using gradient discretization method [30], which covers large class...

Fractures of the third carpal bone (C-3) include small osteochondral fragments (chip fractures), frontal slab fractures of the radial (most common) or intermediate fossae, or both, sagittal slab fractures, most commonly occurring in the radial fossa, and table surface collapse resulting in subchondral lucency of C-3. Small osteochondral fragments are the most common fracture type, and involve o...
