Bone mineral content and mechanical strength of the femoral neck

Bone mineral content and mechanical strength of the femoral neck

N Dalén et al. Acta Orthop Scand. 1976 Oct.

Abstract

The bone mineral content of the femoral neck of 61 autopsy specimens was assayed by x-ray spectrophotometry. The mechanical strength of the specimens was also determined experimentally by applying a compressive force perpendicularly to the shaft. The ultimate force at fracture was obtained from force/displacement plots. A coefficient of correlation of 0.89 between bone mineral content of the femoral neck and the ultimate force at fracture was found. Even when limited to a group of women aged 67-80 a fairly close correlation was found. This indicates that the bone mineral level, measured in vivo, can be used as a criterion of the risk of fracture in elderly women.
