english: And that demarcation that you can see between the original bone and the new bone acts as a very slight point of weakness, so actually now the surgeon can come along, can harvest away that new bone, and the periosteum can grow back, so you're left with the leg in the same sort of state as if you hadn't operated on it in the first place.
non_english: Ova granica koju vidite između originalne kosti i nove kosti deluje kao mala slaba tačka, i sad hirurg može da ide dalje. Može da uzme tu novu kost za transplantaciju i pokosnica može ponovo da izraste, i ostaje vam noga u istom stanju kao da je uopšte niste ni operisali.
