    Abstract: The prosthetic mini-condyle is for use with a prosthetic glenoid fossa. The mini-condyle covers an excised natural condyle having a superior cut surface and a lateral cut surface. The mini-condyle has a superior, convexo-planar articular face and an inferior flat face. A shank extends inferiorly from the inferior face and is adapted to become secured to the lateral cut surface. The flat interior face is adapted to abut against the superior cut surface. Preferably, a porous bicompatible coating is bonded to the inferior face of the condyle and to the medial face of the shank.

  • Patent number: 4778472
    Abstract: The surgical TM joint implant has two-parts: a first part which covers or replaces the natural glenoid fossa and articular eminence of a natural TM joint, and a second part which replaces the natural condylar head of the joint. The first part includes a plate having a fossa cavity defined by a relatively deep concave portion and an anteriorly located concavo-planar portion. The second part has a condylar head defining a convexo-planar, articular face for engaging the concavo-planar surface and establishing therewith a planar contact area which minimizes the unit stress transmitted between the first and second parts, thereby providing for an even load distribution between their engaged planar surfaces.
