A hip replacement is performed by separating a femoral head from a femoral neck in a patient's body, fragmenting of the femoral head, 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 (50), formed of bio-absorbable material, through a hole formed through the femoral head, and the femoral neck (96). The molding device includes an expandable balloon (80) which is expanded by the introduction of molding material, whereby the balloon forms the shape of the neo-femoral head.

Le moulage est exécuté par insertion d'un dispositif de moulage, formé d'un matériau bioabsorbable, dans un trou formé dans la tête et le col de fémur. Le dispositif de moulage comprend un ballonnet dilatable qui se déploie lors de l'introduction d'un matériau de moulage, le ballonnet donnant la forme de la tête néo-fémorale.
