Abstract
A new composition is disclosed which serves as a substitute for the bony matrix material present in bones. The new composition includes an association of collagen-hydroxy-apatite and a glycosaminoglycan. The concentration of the hydroxyapatite is preferably 15 to 25% and the concentration of the glycosaminoglycan is between 1 and 2% per liter of 1% collagen gel. The biomaterial product is useful in applications in reconstructive orthopedic surgery as a substitute for natural bone matrix material.
