BACKGROUND Fracture morphology is crucial for the clinical decision-making process preceding spinal fracture treatment. The presented experimental approach was designed in order to ensure reproducibility of induced fracture morphology. RESULTS The presented method resulted in fracture morphology, found in clinical classification systems like the Magerl classification. In the calf spine sample...

background at altnagelvin, a district general hospital in northern ireland, we have observed that a significant number of hip fracture admissions are later readmitted for treatment of other medical conditions. these readmissions place increasing stress on the already significant burden that orthopedic trauma poses on national health services. objectives the aim of this study was to review a ser...

OBJECTIVES Use of titanium prostheses for reconstructing chest wall defects following major chest wall resections is rapidly increasing in popularity. Previously, complications including prosthesis fracture have been reported for the system secured to the rib ends using clips following chest wall reconstruction and pectus excavatum repair. By contrast, fracture failure in titanium systems faste...

Stochastic simulation of fracture systems is an interesting approach to build a set of dense and complex networks. However, discrete fracture models made of planar fractures generally fail to reproduce the complexity of natural networks, both in terms of geometry and connectivity. In this study a pseudogenetic method is developed to generate stochastic fracture models that are consistent with p...

The aim of this study was to evaluate the fracture strength of teeth with different cavosurface margin cavity preparations and restored with composite resin and different adhesive systems. Eighty premolars were randomly divided in 8 groups, as follow: G1- sound teeth; G2- MOD preparation (no restoration); G3- Adper Single Bond without bevel preparation (butt joint); G4- Adper Single Bond with b...

INTRODUCTION The resistance to fracture of endodontically treated teeth restored with esthetic post systems has not been extensively researched. This in vitro study compared the fracture patterns of endodontically treated teeth with esthetic post systems with different analysis methods. MATERIALS AND METHODS A total of 26 recently extracted human maxillary central incisors were decoronated an...

carpal fracture-dislocation is regarded as an unusual orthopedic injury and, thus, orthopedic surgeons are less experienced in dealing with and treating these fractures and dislocations. we report a 20-year-old worker man suffering from an unusual carpal fracture-dislocation. there was trans-scaphoid fracture and lunate dislocation with other carpal proximal bones toward volar of the wrist. two...
