摘要:
Bone graft compositions including bioactive glass scaffold and characterized in that the bioactive glass scaffold has a high compressive strength, is osteoconductive and osteostimulative and resorbs at a rate consistent with the formation of new bone are described. Also, methods of using the bone grafts for regeneration of hard tissues and, especially, for treating or correcting developmental dysplasia of the hip are provided.
