Generally implant property mismatch with the bone. After some time of surgical implantation there may be chance of micro-crack generation at the bone-implant interface. so, how can we monitor the crack length and crack propagation direction?
Hi Ajay,
Not sure if you are talking about the cracks on the bone or the implant. Anyway, the cracked bone surfaces tend to be mineralised very quickly and you can use calcein or tetracycline to stain such surfaces and detect them using histology (sensitive and specific to some degrees). For in vivo study you may need scintigraphy (sensitive, but not specific or accurate).
