Results of bone morphometry of each zone in the fractured and necrotic femoral head. (A) Bone volume/total volume; (B) Trabecular number; (C) Trabecular separation; (D) Trabecular thickness. Data is presented as a mean ± standard deviation PCTZ = proximal compressive trabeculae zone, NZ = necrotic zone, JZ = junctional zone, SZ = sclerotic zone, DCTZ = distal compressive trabeculae zone, TTZ = tensile trabeculae zone; *P < 0.05.
