摘要： A prosthesis (13) is provided which includes at least two intersecting cone-like bodies (18,20) whose outer surfaces engage the end of a patient's bone (28). Cavities (180,200) for receiving the cone-like bodies (18,20) can be readily formed in the patient's bone with a high level of precision. Through the use of the two cone-like bodies, the prosthesis can have neutral version and yet be used at various version angles without sacrificing the integrity of the patient's bone or the degree of securement of the prosthesis.

摘要： A sinterable coating for an implantable prosthesis is provided having 1) interstices into which tissue or bone can grow, and 2) increased surface roughness which provides enhanced initial press-fit fixation. The coating includes at least two sets of particles having different mean diameters. The sizes and numbers of particles are chosen so as to produce a matrix of smaller particles in which are embedded a lesser number of spaced-apart larger particles. The smaller particles provide support for the larger particles, and the larger particles stand proud of the smaller particles to provide the enhanced surface roughness.

摘要： An implantable article includes a textured bone engaging surface having a surface texture pattern formed by a plurality of furrows separated by ridges that are integral with the base material from which the article is formed. The furrows are formed by ablating in the surface a series of intersecting holes. The side walls of the furrows have scalloped edges. The ablating energy can be applied by techniques such as laser ablation and hydrojet ablation.

摘要： An oblong acetabular cup which includes a cavity for receiving a bearing element is provided. The plane of the opening into the cavity is skewed relative to the prosthesis' longitudinal plane so as to achieve adduction correction, anteversion correction, or both adduction and anteversion correction. In certain preferred embodiments, the prosthesis is constructed from two components which can be oriented with respect to one another to achieve different directions and amounts of anteversion correction. In some embodiments, the two components form a cusp in the outside surface of the prosthesis. Surgical instruments and surgical methods for implanting the prostheses are disclosed.

摘要： An orthopaedic prosthesis system for replacement of an articulating portion of a long bone includes a sleeve, a stem, and a neck. The sleeve has an outer bone engagement surface and includes opposed proximal and distal female taper regions. The stem has a distal end for fixation within a long bone and a proximal end including a male taper region engaged with the distal female taper of the sleeve. The neck has a taper post that engages the proximal taper of the sleeve. Both the neck and the sleeve may define axial bores, the axial bore in the sleeve communicating with and being generally coaxial with the two opposed female tapers, and the neck axial bore extending through the taper post. A connecting element can engage the stem, pass through the axial bore in the sleeve, extend into the axial bore in the neck taper post, and engage the neck.

摘要： An acetabular cup for use with a plastic socket bearing is provided. The cup includes a circular aperture having a stepped configuration. A domed disc is inserted in the aperture and deformed to seal the aperture. In this way, plastic particles, which are generated by wear of the bearing during use, are prevented from migrating through the aperture to the bone surrounding and supporting the prosthesis.
