Abstract
A system for implanting an acetabular prosthesis includes a striker arrangement having a handle and a striker shaft with a distal end configured to engage an acetabular prosthesis. An elongate buttress shaft defines a longitudinal axis and is configured to receive the striker shaft therethrough; it is attachable to the striker shaft such that the distal end of the striker shaft extends beyond a distal face of the buttress shaft. The distal face has a larger diameter than a diameter of the distal end of the striker shaft and has a curved surface oriented transversely to the longitudinal axis.
Claims16
A system for implanting an acetabular prosthesis, comprising:
- a handle including a proximal end and a distal end;
- a solid striker shaft having a proximal end configured for threaded attachment to the distal end of the handle and a threaded distal end for securing the striker shaft to an acetabular prosthesis, the striker shaft including an attachment feature and further including a knob disposed toward the proximal end thereof and extending radially outward therefrom, the knob being sized and shaped to facilitate hand-tightening of the threaded attachment between the handle and the striker shaft;
- and
- a hollow buttress shaft having an open proximal end, an open distal end, and a central channel extending along a longitudinal axis and between the open ends, the channel being sized and shaped to receive the striker shaft therein, the buttress shaft including an attachment feature configured to cooperate with the attachment feature of the striker shaft to secure the buttress shaft to the striker shaft, the attachment feature of the buttress shaft being positioned such that the distal end of the striker shaft extends through the open distal end of the buttress shaft when the buttress shaft is secured to the striker shaft with the attachment features, the buttress shaft further including an outside surface defined by a first diameter over a length of the buttress shaft, and wherein the distal end of the buttress shaft has a second diameter larger than the first diameter and includes a face oriented transversely to the longitudinal axis, the face having a curved surface positioned to contact an inside surface of an acetabular prosthesis when the buttress shaft is secured to the striker shaft with the attachment features and the acetabular prosthesis is secured to the distal end of the striker shaft.

A system for implanting an acetabular prosthesis, comprising:
- a striker arrangement including a handle and a striker shaft having a distal end with threads configured to engage an acetabular prosthesis;
- a tubular buttress shaft configured to be positioned over an outside surface of the striker shaft and secured to the striker shaft such that the threads extend beyond a distal end of the buttress shaft, the distal end of the buttress shaft including a curved surface oriented transversely to a longitudinal axis of the buttress shaft, the curved surface including an annular groove disposed therein configured to receive an elastomeric ring, the groove opening in a direction generally parallel to the longitudinal axis of the buttress shaft;
- and
- an insert impactor configured to impact an edge of an acetabular insert to seat the acetabular insert in an acetabular cup, the insert impactor including a handle and an impactor tip having a generally rectangular impactor surface with a plurality of striations thereon.
