Abstract
An improved polymer orthopedic implant and a method for making the same, where a portion of the implant for engagement with a patient's bone has a rough texture for encouraging micro-ingrowth between the bone and the implant. Substantially all remaining non-bone engaging portions of the implant are smooth for discouraging tissue ingrowth with the implant. The non-bone engaging portions of the implant are polished smooth, and are preferably transparent or translucent. The implant may be comprised of a slow reacting polymethylmethacrylate acrylic.
Claims3
A polymer orthopaedic implant comprising;
- a solid block of polymer medical grade implantable polymethylmethacrylate acrylic bone cement material having a rough textured portion for engagement with a patient's bone to encourage micro-ingrowth between the bone and the implant;
- and
- a smooth transparent surface immediately adjacent the rough textured surface on a non-bone engaging portion for discouraging tissue ingrowth with the polymer implant.
A polymer craniofacial implant comprising;
- a transparent solid block of medical grade implantable polymethylmethacrylate acrylic polymer material having a first smooth superior surface and a first smooth inferior surface;
- and
- a rough textured edge surface intermediate the first smooth superior surface and the first smooth inferior surface of the implant to engage a patient's bone is provided for encouraging micro-ingrowth between the bone and the implant.
An orthopaedic implant comprising:
- a single solid block of medical grade implantable polymethylmethacrylate acrylic material having a beveled and rough textured surface on a portion of the implant for engagement with a patient's bone to encourage micro-ingrowth between the bone and the implant, and
- first and second smooth surfaces adjacent the rough textured surface on a non-bone engagement portion of the implant to discourage tissue attachment and adhesions, and a portion of the implant having the first and second smooth surfaces of the implant is transparent.
