[Stress reactions--stress fracture of the upper femoral neck in endurance sports].
Stress reactions of the musculoskeletal system may be interpreted as possible precursors of stress fractures. Biological material, in contrast to artificial products, can react in numerous and complex ways. This can not only lead to a continual weakening of the tissue, but also to adaptation phenomena in response to overuse. The causes of such stress reactions are still unclear in many respects. For example, it is unknown to what extent a predisposition to these stress symptoms is created by mechanical stress alone or whether other factors such as physical condition, nutrition or even hormone balance come into play. Early diagnosis considerably reduces the healing process and, the later the diagnosis of the stress reaction, the more drawn out is the healing process and the extent of the athlete's absence from training. In this connection may be discussed whether the stress reaction can be the represent as the precursor of the stress fracture. In light of the need for taking special care in obtaining anamnestic data and determining the predisposition of an athlete, it appears to be justified to perform whole body bone scanning in the initial stages and particularly after an innocuous radiological finding. To what extent more current methods (e. g. MRI) can be applied without exposing the athlete to undue radiation cannot be conclusively judged at present. The treatment of a stress reaction should, at least at the beginning, be the same as for a diagnosed stress fracture.
