Some tissues can be donated during life. Bone grafts can make an enormous difference, restoring health and mobility to many patients. At some hospitals, patients undergoing hip replacement surgery are asked if they would be willing to donate the bone they will lose anyway during their operation. This can be used for bone grafts in patients who have lost bone due to disease, trauma or as a result of previous surgery. Many such donations are needed to provide enough bone to meet requirements.
Certain sight-saving operations rely on a rather unusual donated tissue – the amniotic membrane that surrounds a baby inside the womb. This tissue is obtained, with their consent, from mothers undergoing a planned caesarean section. A single membrane can help up to 60 patients.
