Cavitation. The chondrocytes (cartilage cells) go through hypertrophication or enlargement and signal the hyalin cartilage to harden into bone. This hardening into bone is called calcification. The calcified hyalin cartilage is impermeable to the diffusion of nutrients. Since the chondrocytes cant receive any nutrients they begin to die and leave small cavities. These small cavities leave room in the hardened bone for blood vessels to travel through.
