Implants retrieved after 18 years show evidence of lamellar bone consisting of multiple layers and multiple osteonic structures.

Elasmoid scales are thin, imbricated scales composed of a layer of dense, lamellar bone called isopedine, above which is a layer of tubercles usually composed of bone, as in " Eusthenopteron ".

As for the bone part of my question, Bone healing plus some other sources lead me to think that the long interval between breakage and " full repair ", where remodelling has occured and lamellar bone is restored, gives a window of some years when the healed fracture is still significantly more vulnerable than the surrounding bone to collagen degradation.
