Ermüdungsbruch, also ein durch zuviel Belastung entstander Bruch wenn ich mich nicht irre.

http://en.wikipedia.org/wiki/Stress_fracture
Bones are constantly attempting to remodel and repair themselves, especially during a sport where extraordinary stress is applied to the bone. Over time, if enough stress is placed on the bone that it exhausts the capacity of the bone to remodel, a weakened site -- a stress fracture -- on the bone may appear. The fracture does not appear suddenly. It occurs from repeated traumas, none of which is sufficient to cause a sudden break, but which, when added together, overwhelm the osteoblasts that remodel the bone.
Stress fractures commonly occur in sedentary people who suddenly undertake a burst of exercise (whose bones are not used to the task). They may also occur in Olympic-class athletes who do extraordinary quantities of high-impact exercise, or in soldiers who march long distances.
Muscle fatigue can also play a role in the occurrence of stress fractures. For every mile a runner runs, more than 110 tons of force must be absorbed by the legs. Bones are not made to stand that much energy on their own and the muscles act as shock absorbers for the excess force. But, as muscles become tired and stop absorbing most of the shock, the bones experience greater amounts of stress. Finally, when muscles (usually in the lower leg) become so fatigued that they stop absorbing any shock, all forces are transferred to the bones.
Previous stress fractures have been identified as a risk factor.[5]
