The concept of early surgical stabilization of long-bone fractures in patients with multiple injuries became firmly established in the 1970s and 1980s. During the 1990s questions were raised about the early total care of all long-bone fractures in these patients. In particular, it was pointed out that patients with severe chest injuries and those with severe head injuries require special consid...

The technology of multiple hydraulic fracture stimulation in horizontal wells has trans‐ formed the business of oil and gas exploitation from extremely tight, unconventional hydro‐ carbon bearing rock formations. The fracture stimulation process typically involves placing multiple fractures stage-by-stage along the horizontal well using diverse well completion technologies. The effective design...

PURPOSE To assess factors that influence 4-year mortality following hip fracture surgery in a Japanese population. METHODS Records of 129 hips in 24 men and 103 women aged 50 to 103 (mean, 79) years who underwent surgery for femoral neck or trochanteric fractures were reviewed. Clinical data reviewed included age, gender, body mass index (BMI), side of fracture, fracture type, fracture stabil...

In this paper dynamic fracture process due to high-speed impact of steel plunger into ceramic sample is simulated. The developed numerical model is based on finite element method and a concept of incubation time criterion, which is proven to be applicable in order to predict brittle fracture under high-rate deformation. Simulations were performed for ZrO2(Y2O3) ceramic plates. To characterize f...

Background:One of the main reasons for extraction of endodontically treated teeth is vertical root fracture (VRF). Some factors such as root canal treatment are involved in vertical root fracture because of their potential to weaken the tooth structure. Therefore, this study aimed to investigate the effect of combining different obturation materials and rotary systems on the fr...

We describe a patient with a traumatic spondylolisthesis of L5 and multiple, bilateral pedicle fractures from L2 to L5. Conservative treatment was chosen, with eventual neurological recovery and bony union. We are not aware of previous reports of this pattern of injury.

BACKGROUND Blunt trauma is the most frequent mechanism of injury in multiple trauma, commonly resulting from road traffic collisions or falls. Two of the most frequent injuries in patients with multiple trauma are chest trauma and extremity fracture. Several trauma mouse models combine chest trauma and head injury, but no trauma mouse model to date includes the combination of long bone fracture...

PURPOSE Osteochondral fractures in skeletally immature patients are rare. A retrospective case series is reported looking at the use of Omnitech compression screws for these injuries. METHOD Nine patients with a mean age of 14 were included in the study with a mean follow up of 26 months. RESULTS The average KOOS, IKDC and Tegner Lysholm Scores were 86.7, 90.34 and 96.1 respectively. CONC...

Colles' fractures are manipulated under a variety of anaesthetic techniques. An increasing awareness of cost and time within the National Health Service contributes to a marked change in the anaesthetic management of Colles' fractures. This paper presents the results of a survey of the anaesthetic techniques used in the larger accident and emergency (A&E) departments of the UK, and demonstrates...
