The risk-benefit ratio is quite favorable at the start of treatment in patients with a good indication, but prolongation beyond 5 years might not further reduce the absolute risk of ordinary fractures, as concluded by the U.S. Food and Drug Administration (Whitaker et al. 2012)—a conclusion that has been partly contested by some researchers in the field (Black et al. 2012).
Some ordinary shaft fractures and atypical femoral fractures may have been misdiagnosed and registered with other diagnostic codes, making them inaccessible for our analysis.
Case-control study Patients with atypical fractures (cases) were compared with 952 control patients with ordinary shaft fractures.
In addition, we performed a case-control analysis with comparison to 952 patients with ordinary shaft fractures.
Ordinary stress fractures in athletes may occur more frequently in women due to a narrower bone (Seeman 2008): the bending strength of the femoral shaft is proportional to the third power of the radius.
The song's mystery seemed to lie somehow in a fracture of ordinary circumstances, as if you had taken a hammer to a mirror and cracked it in such a way that it now reflected a multiplicity of images.
As bones lose density, they become fragile and unable to withstand ordinary strains; the resulting fractures, particularly of the hip, may cause incapacitation and even death.
As an upcoming report in Physical Review Letters describes, the behavior of this material is bizarre even when it is changing into ordinary ice: It suddenly fractures into tiny crystals, allowing underlying material to erupt, much like a terrestrial volcanic eruption.
One of the advanced materials is a toughness enhanced, fine-grained tungsten material (W-TiC) having four-times larger fracture toughness than ordinary tungsten and appreciable RT ductility in the recrystallized state.
In the analyses we did not consider fractures caused by metastatic cancer, but cases of fractures due to suspected high impact trauma were, as recommended, 36 37 retained in the analysis since these fractures are—as ordinary fragility fractures also more common in those with low bone mineral density.
