Spacer with a coating thereon for use with an implant device
First Claim
1. A method for healing bone comprising:
- situating a bone plate adjacent a bone, the bone plate having at least one aperture;
inserting at least one spacer into the at least one aperture of the bone plate to space the bone plate from the bone and decrease the area of contact between the bone and the bone plate, wherein the spacer includes a bone healing surface that projects beyond an underside surface of the bone plate, wherein the spacer is bioresorbable and includes a coating on at least a portion of the bone healing surface, and wherein the coating is in contact with the bone and comprises effective amounts of a therapeutic agent, a polymeric carrier and a buffer medium; and
securing the bone plate to the bone.

Abstract
The present invention relates to a spacer, such as a polymeric spacer, for use with an implant device, e.g., a bone plate, for splinting a fracture of a bone. The spacer includes a body defining a bone healing surface, wherein at least a portion of the bone healing surface has a coating which includes a therapeutic agent, a polymeric carrier, and a buffer medium to stimulate bone growth and/or promote fracture healing. A kit is also disclosed which includes one or more of the spacers, at least one bone plate, and optionally one or more bone screws for securing the bone plate to bone. A method for promoting fracture healing in bone is further disclosed which includes securely situating a coated portion of the spacer adjacent bone.
