A PROCESS TO TREAT AVASCULAR NECROSIS (AVN) WITH OSTEOINDUCTIVE MATERIALS

摘要

A method of treating avascular necrosis ("AVN") comprising administering one or more osteoinductive formulations to the site of AVN disease progression. The method involves the combination of a core decompression technique, followed by the introduction of one or more osteoinductive formulations into the decompression core, and concluding with capping of the ateral aspect of the decompression core with a femoral core cap. The osteoinductive formulations of the invention comprise one or more osteoinductive agents and suitable carrier molecules. The femoral core cap retains the osteoinductive formulation within the decompression core, thereby preventing leakage of the osteoinductive formulation from the decompression core. The method of the invention optionally comprises introduction of autograft or allograft with the osteoinductive formulations of the invention. The method of the invention further optionally comprises incorporation of sustained release compositions to provide extended periods of osteogenesis.
