Abstract
A bone augment for repairing a bone defect. The bone augment includes a porous body and a metallic liner. The porous body defines a bore and is configured to be intraoperatively shaped to correspond to the bone defect. The metallic liner is injection molded within the bore such that portions of the liner interlock with pores of the porous body. The metallic liner is operable to mount an implant to the bone augment.
Claims13
A bone augment for repairing a bone defect comprising:
- a porous body that defines a bore, the porous body is configured to be intraoperatively shaped to correspond to the bone defect;
- and
- a metallic liner secured within the bore, the metallic liner including a first coupling surface within the bore and a second coupling surface within the bore;
- wherein the metallic liner includes a main body having a first locking surface and a cap having a second locking surface that is operable to engage with the first locking surface to secure the cap to the main body.
