background: hip fractures are serious fall injuries that often result in long-term functional impairment and increased mortality. as the population ages, the number of hip fractures is likely to increase worldwide. the main objective of this pilot study was to evaluate the risk factors of hip fracture among the older adults in the lebanese population. methods: this pilot epidemiological, prospe...

BACKGROUND The most common mechanical failure in the internal fixation of trochanteric hip fractures is the cut-out of the sliding screw through the femoral head. Several factors that influence this complication have been suggested, but there is no consensus as to the relative importance of each factor. The purpose of this study was to analyse the cut-out complication with respect to the follow...

This retrospective study is performed on 423 cases of skull farcture who refered to "Loghman-e­Hakim" hospital during a 493 days period (October 1994-March 1995): The fracture types were linear in 85% Depressed in 7%, Basilar in 8% of cases. 71.2% of all cases were male and 28.8% were femal. 72.6% of fracture occured in pediatric age group "Less than 15 years old" and 27.4% in adult group. The ...

Data on long-term consequences of non-hip non-vertebral (NHNV) fractures, accounting for approximately two-thirds of all fragility fractures, are scanty. Our study aimed to quantify the population-wide impact of NHNV fractures on mortality. The national population-based prospective cohort study (Canadian Multicentre Osteoporosis Study) included 5526 community dwelling women and 2163 men aged 50...

A 55-year-old woman developed an atraumatic sternum fracture during treatment with alendronate for osteoporosis. The woman received alendronate 70 mg in combination with cholecalciferol 5600 IU once weekly, as well as nonsteroidal anti-inflammatory drugs. After 4 years of treatment, following a dorsal flexion with no direct thoracic trauma, the patient suffered a fracture of the sternum, with a...

AIM To compare the bond strength and the fracture resistance of different post systems. MATERIALS AND METHODS Endodontically treated 60 mandibular incisor and 60 mandibular premolar teeth were used for the bond strength and fracture resistance test respectively. For each test, three groups (n = 20) were formed according to the posts used zirconia posts (ZR post), individually formed glass fib...

Some cases of infant skull fracture fall under the category of forensic study where it is not obvious whether the head trauma happened due to an accident or abuse. To be able to determine the cause of the head trauma with sufficient accuracy, biomechanical analysis using finite element modeling of the infant cranium has been established. By simulating the trauma, one may be able to obtain the f...

Fracture assessment of U- and V-notches is important in mechanical engineering. One can use the J-integral as fracture parameter in order to predict the critical fracture load in notches. The critical value of the J-integral in cracks is a function of the material properties. In notches, however, the material properties as well as the notch dimensions affect this critical value (named fracture ...

A retrospective study of 30 patients (12 alcoholics and 18 nonalcoholics) was performed to determine whether the fracture healing time (T) was longer in alcoholics and smokers. Fracture healing time (mean ± standard error) was longer in alcoholics (24.1 ± 5.8 weeks vs. 11.4 ±1.1 weeks in nonalcoholics, p=0.001) and in 21 smokers (15.8 ± 2.9 weeks) vs. 9 nonsmokers (18.2 ± 5.9 weeks) (p=0.045). ...

*Correspondence: Alex Hansen, Department of Physics, Norwegian University of Science and Technology, N–7491 Trondheim, Norway e-mail: [email protected] We propose a mapping from fracture systems consisting of intersecting fracture sheets in three dimensions to an abstract network consisting of nodes and links. This makes it possible to analyze fracture systems with the methods developed withi...
