Theory 23/Bone remodelling/Progression phase
Balance Is Resorption Against Formation
The claim
Net bone change per cycle is set by the ratio of resorption depth to formation refill, so a small uncoupling compounds over years.
01Mechanism
Each cycle removes and replaces; the ratio determines the net.
02Prediction
Net loss should track the ratio.
03Refutation
Net loss tracking resorption alone would remove refill.
