PURPOSE OF THE STUDY Diabetics may have an increased fracture risk, depending on disease duration, quality of metabolic adjustment and extent of comorbidities, and on an increased tendency to fall. The aim of this retrospective one-centre study consisted in detecting differences in fracture healing between patients with and without diabetes mellitus. Data of patients with the most common fractu...

BACKGROUND Blow-out fracture of the orbit is a common injury. However, not many cases are associated with massive subcutaneous emphysema. Even fewer cases are caused by minor trauma or are associated with barotrauma to the orbit due to sneezing, coughing, or vomiting. The authors present a case of blow-out fracture complicated by extensive subcutaneous and mediastinal emphysema that occurred wi...

We present a case of patellar fracture with avulsion fracture of the tibial posterior cruciate ligament (PCL) attachment; to our knowledge, this is the first report of its kind. Patellar fracture is often accompanied by anterior knee pain, which can make it difficult to perform the draw test and thereby mask the PCL injury. Moreover, cases of avulsion fracture of the tibial PCL attachment are r...

BACKGROUND Zygomatic arch is a bony arch constituting the lateral midface, which consists of 25% of all midface fractures. There are a number of ways to evaluate the extent of zygomatic arch fracture. Some authors have reported successful treatment outcomes using ultrasound (U/S). To add to the previous methods, we have considered ways to accurately display the location of the fracture line whi...

fault zones and fault-related fracture systems control the mechanical behaviors and fluid-flow properties of the earth’s crust. furthermore, nowadays, modeling is being increasingly used in order to understand the behavior of rock masses, and to determine their characteristics. in this work, fault zones and fracture patterns are reviewed, and also comprehensive studies are carried out on the fr...

The objective of the paper is to study the effect of cyclic loading on the fracture resistance of the SA 333 Gr.6 carbon steel material of the primary heat transport (PHT) system piping of Indian pressurized heavy water reactors (PHWR). Tests have been carried out on compact tension specimens machined from the pipe used in the PHT system. The effect of load ratio, incremental plastic displaceme...

In order to characterize the fatigue behaviour and determine the fracture energy of polysilicon used in micro-systems, an on-chip testing device has been designed and fabricated. The experimental set-up is able to continuously measure the elastic stiffness decrease and therefore to evidence fatigue of polysilicon 15-μm thick films and to allow for the introduction of a sharp crack at the notch ...
