An implantable endoprosthesis is adapted to articulate with one or more prosthesis surfaces, and is at least partially formed from a material having high wear resistance, which may be a polymeric material such as ultra-high molecular weight polyethylene (UHMWPE), polyetherether ketone (PEEK), and the like, or a metallic material, such as a cobalt-chrome alloy, or a ceramic material, such as alumina or zirconia. The body member of the endoprosthesis may be formed from a composite material, and includes at least a first component formed from a first material having increased wear resistance as compared to that of a second material forming a second component of the body member. The second material is generally more resilient as compared to the first material.

Wear-resistant endoprosthetic devices

The invention relates to a technique for precisely locating a line containing a predetermined point within the surgical site using a series of levels and plumb lines and internal anatomical features of the surgical site, using this location to precisely position and temporarily affix a site preparation scaffold relative to the patient's anatomy so that site preparation instruments can be introduced into the site at precise locations governed by the scaffold geometry and patient anatomy. This precise positioning of the scaffold also provides a way for the surgeon to use patient anatomical features to reliably and precisely prepare the surgical site. Scaffolds having angling features further increase the precise preparation of the surgical site. This increased precision in site preparation increases the probability of a successful procedure, and decreases the likelihood that additional surgery may be needed.

Method and apparatus for stereotactic implantation

The methods and apparatus of this invention provide instrumentation for clamping and securing instruments to support members. Specific embodiments of the invention are particularly useful as devices and methods for use during surgical procedures, such as implantation procedures to properly implant a prosthesis.
