摘要： The cotyloidal implant has a hemispherical cup (5) forming an internal cavity (10), and an insert (7) engageable into the cavity, the cup being set in place by impaction and having to this effect anchoring asperities (15) provided on its external face, having the form of lozenges and which are contiguous and imbricated. The cup (5) is provided, on its external face, with two coaxial grooves configured like helical threads (38) having reverse pitches which intersect each other on a large portion of said external face, which are inclined in the direction of the cup opening and which have a depth increasing progressively in the opening direction of the cup (5); due to their intersection, the grooves delimit an important number of asperities (15). The invention provides for the making of a cotyloidal implant which can be anchored to the pelvis without the use of cement and screws.

摘要： An implantable orthopedic prosthesis. A prosthetic component includes a wall having a first surface for engaging bone and a second surface. The wall defines a hole therethrough extending from the second surface to the first surface. A plug is removably disposed in the hole. The plug includes a peripheral rim spring-biased radially outwardly in frictional engagement with the sidewall of the hole. The plug is useful for occluding the hole to alleviate the risk of polyethylene wear particles migrating through an unused hole into contact with bone.

摘要： A cemented acetabular prosthesis includes a cup body having a relative thin wall (for example, 2 mm). The body has a concave surface, a convex surface, and an annular rim. A plastic liner registers into a concavity of the cup body, the liner having a wall with a liner wall thickness much greater than the cup body wall thickness and a concave surface and a convex surface that registers and fits the concave surface of the cup body. The cup body wall provides a plurality of openings. Some of the openings are bone screw receptive openings that are reinforced with an annular reinforcement that extends away from the convex surface of the cup body. Other openings are unreinforced openings that allow cement to flow from the concave to the convex side of the cup body and into the patient's acetabulum during surgery. The cup body has a peripheral buttress portion for supporting a volume of cement of the cement mantle at a peripheral interface position between the liner and the body.

摘要： A joint prosthesis having two mutually articulating components that are made of a metal alloy. One of the components is made of an alloy having a low carbon content (0.03 to 0.10 wt. %) and the other component is made of an alloy having a high carbon content (0.18 to 0.35 wt. %). The articulating components may be, for example, a hip head prosthesis and an acetabular cup prosthesis.

摘要： An acetabular shell can receive bone screws through a screw hole that is initially occluded by a plug in sintered connection with the wall of the screw hole. The sintered connection can be broken to permit removal of the plug, if desired. The plug prevents migration of wear debris from the interior of the shell to the exterior of the shell through an unused screw hole.

摘要： An acetabular cup assembly having a non-metallic inner cup to be positioned within a metal shell with a dome shaped interior surface. The non-metallic inner cup is formed with a plurality of interconnecting grooves and ribs. The ribs are configured to contact the interior surface of the metal shell while the grooves have inner surface areas spaced from the interior surface of the metal shell. The combination of the ribs and the groove define cavitites in the outer surface of the inner cup. The assembly further includes groove insert members that are configured to be positioned in and filling substantially all of the cavities.

摘要： The insertion instrument of this invention includes a generally cylindrical handle portion and a cup engaging portion held in a spaced relationship by an arcuate intermediate portion. Handle portion includes a longitudinal throughbore and an impaction head. The cup engaging portion includes a rotatable threaded stud for threaded accommodation within a threaded hole of an prosthetic acetabular cup. The stud includes a head having a recess formed therein for accommodating a driving device. The longitudinal bore of the handle portion and the head of the threaded stud are placed in alignment such that the shaft of a screwdriver extending through the threaded bore is aligned with the head of the screw. Therefore, a surgeon using the instrument of this invention does not need to have a clear view of the threaded stud to attach a screw driver. This is especially useful after the surgeon has impacted the acetabular cup within a prepared acetabulum and needs to remove the insertion instrument. Often, the head of the screw may be obscured from the surgeon by the depth of the wound. This instrument provides for the easy alignment of the driver and the head of the threaded stud.

摘要： The outer shell possesses openings in the polar or apical region which serve to backfill the implanted shell with spongious bone material. The openings are separated by a web which extends through the axis of symmetry of the outer shell and which has a threaded bore to receive an insertion instrument. The instrument is centrally guided on an axial direction to facilitate control and alignment of the outer shell during insertion, especially in the case of outer shells to be screwed in with a self-cutting thread.

摘要： A cup impactor (1, 1′, 1″) is provided, adapted to assist a surgeon in controlling implantation of a cup prosthesis (9). The impactor has an impactor body (8), a drive train assembly (71), an impactor nose (38), and a clamping handle (5). The impactor body (8) has on its proximal end, an impaction plate (7) connected thereto, and an impactor handle (6) formed thereon for handling by the surgeon and, on the distal end, an impactor cup support portion (8a) having a receiver recess (8b) therein. A drive train assembly (71) has a prosthesis engaging interface (11) at a distal end thereof, and a proximal end on which a positioning knob (2) is formed. The assembly (71) received and rotatably mounted in the receiver recess (8b) of the body (8) so as to expose the prosthesis engaging surface (11). An impactor nose (38) mounts on the distal end of the impactor body (8), through which the prosthesis engaging interface (11) extends. A clamping handle (5) pulls distal portion of the drive train assembly (71) and therefore any cup prosthesis (9) attached to the engaging interface (11) against the impactor nose (38) so as not to strain the proximal end of the drive train assembly (71).
