Bone phosphorus/hydroxyproline ratio and bone histomorphometry in normals

Bone phosphorus/hydroxyproline ratio (P/Hypro) was compared to bone histomorphometry in thirty-four normal individuals. Bone P/Hypro ratio correlated significantly to both the relative mineralized bone volume (r = 0.38, P less than 0.05), the relative osteoid volume (r = -0.38, P less than 0.05) and the percentage of osteoid covered surfaces in trabecular bone (r = -0.38, P less than 0.05).
