In the case of slipperiness and ice accident traumatologists have a lot to do, the number of fractures, especially on the forearm and femoral neck, is increasing rapidly. But fractures are not only an issue in winter: In addition to these common fractures caused by falls, in which only one bone is affected, it can also lead to significantly more complicated fractures, for example, by traffic accidents.

Bones - a hard framework for the soft core

Our bony body structure accounts for about 20 percent of our weight, anchors muscles and ligaments and protects our internal organs in the head, chest and pelvic area. Almost 50 percent of bones are inorganic material such as calcium phosphate, 25 percent connective tissue and 25 percent water. They are very stable, a full-grown bone can withstand a pressure of up to 15 kilograms per square millimeter - so a thigh bone can carry a total of well over 1.5 tons.

How does a fracture develop?

In spite of the enormous load capacity a bone can not escape due to its brittle, hard substance with stronger force acting on the bony skeleton - a bone crack (fissure), a bone fracture (fracture) or even a splintering of the bone into several parts (multiple fractures, complicated fracture) arises.

The way the bone breaks is pure physics. Depending on the force produced:

  • a smooth breakthrough
  • a breakthrough with blasted bone fragment on the opposite side
  • a spirally twisted bone fracture site or
  • many bone fragments

In childhood, the bone is not so brittle and can give better: There are often the so-called Grünholzfrakturen. In the case of greenwood fractures, the bone only breaks on one side or it is compressed or the sensitive periosteum is injured, but the bone holds firm.
