Vertebral implant for bone fixation or interbody use
First Claim
1. A biodegradable bone stabilization system comprising a stabilization member which is selectively positioned and secured relative to at least two bone segments within a bone column, to support one of the bone segments with respect to at least one other bone segment, implant or graft material within the bone column, for the purpose of maintaining distance, geometry and continuity between at least two bone segments, wherein the at least one stabilization member is formed of a material that provides structural support of at least a predetermined amount while concomitantly having a biodegradation rate such that the structural integrity of the implant is maintained for sufficient time to allow bone healing between the at least two bone segments, with subsequent complete removal from the bone column.

Abstract
The present invention provides a biodegradable implant which can be used as fixation and/or interbody implants. The implant is formed of a biodegradable material and may be used as a cervical stabilizing system. The stabilizing system comprises a body constructed of a biodegradable, polymeric material, which when implanted within the body will maintain a predetermined structural integrity for at least a predetermined period of time while minimizing reactivity with adjacent tissues. In an embodiment of the invention, the stabilization system comprises a fixation member which includes apertures to allow selective coupling to bone segments by means of biodegradable screws. In another embodiment, the stabilization system includes a bone column implant which maintains space between at least two bone segments of a bone column. The body member is dimensioned to substantially maintain the distance, geometry and continuity between the at least two bone segments. The invention is also directed to a combination device comprising a fixation device along with an interbody implant and methods for using the stabilization system.

14. A biodegradable interbody implant comprising,
a body member being configured to be positioned between at least two bone segments within a bone column, to support one of the bone segments with respect to at least one other bone segment, implant or graft material within the bone column, for the purpose of maintaining distance, geometry and continuity between at least two bone segments, wherein the interbody implant is formed of an e-caprolactone monomer material, the material having a biodegradation rate to provide sufficient structural integrity for an amount of time for bone healing between the at least two bone segments.
-
15. A biodegradable bone fixation plate implant comprising,
a plate member being configured to be positioned laterally adjacent and attached to at least two bone segments within a bone column, to fix the bone segments with respect to one another, wherein the fixation plate is formed of an e-caprolactone monomer, the plate having a biodegradation rate to provide sufficient structural integrity for an amount of time for bone healing between the at least two bone segments.
-
20. A method for stabilizing a bone column utilizing at least one biodegradable implant, the comprising the steps of,
positioning the implant relative to the bone column, attaching the implant to position at least two bone segments in a desired position relative to one another, wherein the implant is formed of an e-caprolactone monomer material, the material having a biodegradation rate to provide sufficient structural integrity for an amount of time for bone healing between the at least two bone segments.
