[Significance of magnesium, copper and zinc in medial femur neck fractures in the aged].

The medial fracture of the femur neck is mainly a fracture of the old man. It is well known, that often only minimal traumas are caused for the medial fracture of the femur neck. Osteoporosis alone is not the reason for fracture. A deficiency in trace elements especially for the old patients is often discussed, but there are no exact examinations yet. For this analysis the concentration magnesium, copper and zinc was performed from 10 patients which got a medial fracture of the femur neck. Bone-biopsy and blood was taken when an endoprothesis was implanted. We could find a decreased zinc concentration in all bones. The copper and magnesium concentration in bone was not significant depressed. Both elements have a great individual spread. There are no significant alterations in blood levels of magnesium, copper and zinc in patients with a medial fracture to normal population.
