The present invention provides an improved technique for spinal fusion
involving the administration of an HMG-CoA reductase inhibitor to a
fusion. The HMG-CoA reductase inhibitor is preferably delivered to the
site by a carrier. More preferably, the HMG-CoA reductase inhibitor is
delivered to the site by a non-compressible delivery vehicle. The
invention is suitable for promoting non-anatomic or heterotopic bone
growth between any bony surfaces where bone growth is desired but does
not naturally occur.
