Where does the bone comes from when you have surgery?

In some surgery, bone grafts are needed. These can come from your own body, most frequently from your pelvis (around the Spina Iliaca Anterior Superior), or fibula (lower leg). Your own hip (Femoral head) can also be used if you are getting a hip prosthesis. Bone grafts can also come from other people. When a person dies, their organs are taken for transplantation (NB: this is diffrent in each country, depending on wether you have an opting-in or opting-out system). Bones are organs too, though you don't consider them as such. Obviously, these bones are processed before used (checked, checked, checked, sterilised, checked,...).
