[Bone infection as a cause of pathologic fracture]

A long persisting chronic recurring ostitis disturbs above all the differentiated conversion of fibrous bone into strong lamellar bone. The more that other factors disturb the vitality and vascularity of the bone, the more dystrophy, sclerosis and so-called crenae develop. Together this leads to new pathological refractures during inflammatory bone processes. To avert these dangers adequate infection prophylaxis and therapy are necessary as well as consistent observance of biomechanical and biological principles.
