The concentration of calcium and phosphorus in trabecular bone from the iliac crest

The concentrations of calcium and phosphorus were determined in central parts of bone trabeculae in the human iliac crest by means of an energy dispersive microanalysis technique. Two age groups, each consisting of six suddenly diseased male subjects, were investigated. It was found that the concentrations of calcium and phosphorus did not differ between young and old men. The obtained mean values were fairly alike and determined to 40 and 17 weight %, respectively.
