Method and kit for repairing a defect in bone
Methods and devices are provided for the repair of bone defects. The bone defect repair may be accomplished by minimally invasive means. The bone defect repair may utilize a bone growth promoting substance. The bone growth promoting substance may comprise a carrier material and at least one osteoinductive formulation.
1. A method of treating an osteolytic lesion comprising:
accessing the osteolytic lesion located at an interface between a patient's bone and an orthopedic prosthetic by inserting a cannula or guidewire through the skin and soft tissue, and dilating the soft tissue with the cannula to provide access to the osteolytic lesion, wherein the osteolytic lesion is caused by particulate induced bone resorption;
preparing the osteolytic lesion for receiving a bone growth promoting substance by debriding a surface of the osteolytic lesion using a debriding device; and
delivering the bone growth promoting substance to the osteolytic lesion via a delivery apparatus selected from a cannula or graft syringe, wherein the bone growth promoting substance is capable of adhering to the osteolytic lesion and comprises: a carrier and at least one or more osteoinductive agents selected from the group consisting of one or more BMPs, one or more VEGFs, one or more CTGFs, osteoprotegerin, one or more TGF-betas, and any combination thereof.
2. The method of claim 1 , wherein the one or more osteoinductive agents are selected from the group consisting of CTGF-1, CTGF-2, CGTF-3, CTGF-4, and any combination thereof.
3. The method of claim 1 , wherein the one or more osteoinductive agents are selected from the group consisting of VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGF-E, and any combination thereof.
4. The method of claim 1 , wherein the one or more osteoinductive agents is osteoprotegerin.
5. The method of claim 1 , wherein the one or more osteoinductive agents are selected from the group consisting of TGF-.beta.-1, TGF-.beta.-2, TGF-.beta.-3, and any combination thereof.
6. The method of claim 1 , wherein the one or more osteoinductive agents comprise BMP-2 and are provided as therapeutic polynucleotides.
7. A method of treating an osteolytic lesion comprising:
accessing the osteolytic lesion located at an interface between a patient's bone and an orthopedic prosthetic by inserting a cannula or guidewire the skin and soft tissue, and dilating the soft tissue with the cannula to provide access to the osteolytic lesion, wherein the osteolytic lesion is caused by particulate induced bone resorption;
preparing the osteolytic lesion for receiving a bone growth promoting substance by debriding a surface of the osteolytic lesion using a debriding device; and
delivering the bone growth promoting substance to the osteolytic lesion, wherein the bone growth promoting substance is capable of adhering to the osteolytic lesion and comprises a carrier and osteoprotegerin.
