INTRODUCTION Posterior dislocation of the hip joint with associated acetabular and intertrochanteric fracture is a complex injury. Early recognition, prompt and stable reduction is needed of successful outcome. CASE REPORT 45 year old male patient presented with posterior dislocation of the hip with transverse fracture with posterior wall fracture of acetabulam and intertrochanteric fracture ...

many large oil and gas fields in the most productive world regions happen to be fractured. the exploration and development of these reservoirs is a true challenge for many operators. these difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. to successfully address these challenges, it is paramount to improve ...

We describe experiments on the dynamic fracture of the brittle plastic, PMMA. The results suggest a view of the fracture process that is based on the existence and subsequent evolution of an instability, which causes a single crack to become unstable to frustrated microscopic branching events. We demonstrate that a number of long-standing questions in the dynamic fracture of amorphous, brittle ...

BACKGROUND Children's fractures have been enlisted among orthopaedics complaints of childhood obesity. Unhealthy lifestyle behaviours may contribute to increased risk. This study described the prevalence of overweight/obesity in children and adolescents reporting a recent fracture in relation to gender, dynamic of trauma, and site of fracture. METHODS Four-hundred-forty-nine children and adol...

Floating ice shelves can exert a retentive and hence stabilizing force onto the inland ice sheet of Antarctica. However, this effect has been observed to diminish by the dynamic effects of fracture processes within the protective ice shelves, leading to accelerated ice flow and hence to a sealevel contribution. In order to account for the macroscopic effect of fracture processes on large-scale ...

Dynamic hip screw and gamma nail have been widely used to treat the patients with proximal femoral fractures, but clinical failures of those implants are still to be found. This study developed three-dimensional finite element models to investigate the biomechanical performances of the implants. Two kinds of commercially available implants (dynamic hip screw and gamma nail) and one newly design...

Proximal interphalangeal (PIP) joint injuries remain challenging to hand surgeons [1]. Painless, stable and mobile PIP joint are the main goals for any treatment option of PIP joint [2,3]. Closed reduction and extension block pins [1,2] Open reduction of PIP joint fractures [3,4] and osteochondral hemihamate autograft arthroplasty [5,6] described for treatment of such difficult injuries. Mainte...

BACKGROUND In treatment of unstable trochanteric fractures dynamic hip screw and Medoff sliding plate devices are designed to allow secondary fracture impaction, whereas intramedullary nails aim to maintain fracture alignment. Different treatment protocols are used by two similar Swedish regional emergency care hospitals. Dynamic hip screw is used for fractures considered as stable within the r...

OBJECTIVE We evaluated the treatment of nonunion of humeral shaft fracture with dynamic compression plate from January 2002 to December 2009. METHODS Twenty-two patients were treated over the study period. Trauma was the predominant cause of injury in 86.4% of the patients. RESULTS Nonunion was atrophic in 81.8% and hypertrophic in 18.2% of the individuals. There was a primary injury of the...
