The fatigue fracture is a kind of microscopic cracks in a bone.
The fatigue fracture derives its name from the science of materials which establishes that a solid element subjected in a durable way to repetitive forces, finally presents, within its structure cracks.
Such structural defects are studied, for example, about planes or bridges for which it is important to detect them before they become the source of disasters!
In humans, the skeleton, subjected to a physical overwork is likely to present this type of cracks.It is the bones of the lower limbs (leg, foot), so-called "bearing" limbs, which are most exposed to fatigue fractures, but the pelvis and lower spine may more rarely be involved.
The type of overwork likely to produce a fatigue fracture includes either jumps, or the bottom run, or even the extended walking type walk.
It can also be noted that, historically, it was in the military environment, following forced marches, that fatigue fractures were observed almost epidemically.
The quality of the skeleton is usually normal, but can sometimes be altered and weakened in case of osteoporosis. This can promote the occurrence of a fatigue fracture.You want to react, to give your testimony or to ask a question? Appointment in our FORUMS or A doctor answers you!
