Sammanfattning
Stress fractures are caused by material fatigue. Microcracks appear normally in bone, and are dealt with by remodeling, specifically targeting
areas of microdamage. Inhibition of targeted remodeling can allow microcracks to grow and form fractures. Intensive athletic training can lead to an
increased microcrack formation rate, which exceeds what can be balanced by remodeling. Stress fractures often heal poorly, possibly because
they are so thin: normal deformation of the bone during loading has been shown to lead to strains within thin cracks that are incompatible with cell
survival. If the patient can’t reduce loading sufficiently to allow healing, surgical stabilization will therefore be required. If the crack is transformed
into a larger defect, e.g. by drilling a hole, strains will be reduced and healing facilitated by a simple procedure.
