ABSTRACT:
A hip replacement is performed by separating a femoral head from a femoral neck in a patient's body, fragmenting of the femoral head and removing the fragments from the body, and molding in-situ in the body a neo femoral head joined to the femoral neck. The molding is performed by inserting a molding device, formed of bioabsorbable material, through a hole formed through the femoral head and the femoral neck. The molding device includes an expandable balloon which is expanded by the introduction of molding material, whereby the balloon forms the shape of the neo femoral head.
