Abstract

Surgical trays, tools and methods for use in hip replacement surgery wherein the hip replacement prosthesis is a reverse hip prosthesis. The trial acetabular cups, tools for inserting and removal of acetabular balls, and a press, enable a surgeon to identify the optimum said components of the reverse hip prosthesis for implantation in a patient based on the sizes and angles best adapted to the patent's anatomy.

Claims (11)

Claims
1. A trial acetabular cup for a reverse hip prosthesis comprising: a cup having an outer convex surface adapted to fit in a prepared surface of an acetabular bone; and an inner concave surface and an internally threaded integral stem extending within the cup from a base; the outer and inner surfaces having an optional through opening; the integral stem being internally threaded and having an end opposite the base, wherein the entirety of the integral stem is within the cup, and further, the integral stem is affixable to a part of a trial acetabular ball having a stem extending therefrom, the stem having a threaded portion, which threaded portion is engaged with threads of the integral stem when the trial acetabular ball is mounted to the trial acetabular cup.
2. The trial acetabular cup of claim 1, where the end of the integral stem is removably affixable to one of differently sized trial acetabular balls.
3. The trial acetabular cup of claim 1 or claim 2, wherein the integral stem has an exterior which is substantially cylindrical between its end and its base within the cup.
4. The trial acetabular cup of any one of claims 1 to 3, wherein the region of the base of the integral stem and the inner concave surface is concave.
5. The trial acetabular cup for a reverse hip prosthesis according to claim 1, affixed and abutting to a trial acetabular ball having a stem extending therefrom, the stem having a threaded portion, which threaded portion is engaged with the threads of the integral stem.
6. The trial acetabular cup of claim 5, wherein the integral stem has an exterior which is substantially cylindrical between its end and its base within the cup.
7. The trial acetabular cup of claim 6, wherein the region of the base of the integral stem and the inner concave surface is concave.
8. The trial acetabular cup of claim 1, wherein the trial acetabular ball has a circumferential groove therein to provide a gripping surface for insertion or removal of the trial acetabular ball into or out of the trial acetabular cup.
9. The trial acetabular cup of claim 5, wherein the trial acetabular ball has a circumferential groove therein to provide a gripping surface for insertion or removal of the trial acetabular ball into or out of the trial acetabular cup.
10. The trial acetabular cup of any one of claims 1 to 9, further with a tool for inserting or removing a trial acetabular ball having a circumferential groove therein to provide a gripping surface for insertion or removal of the trial acetabular ball into or out of the trial acetabular cup, the tool comprising a handle at its proximal end proximate a ratcheting portion, grippers at its distal end, and a hinge disposed between the proximal and distal ends, the tool being adapted to grip the circumferential groove of the trial acetabular ball.
11. The trial acetabular cup of any one of claims 1 – 9, further with a press for pressing a polymer liner into a femoral cup for the reverse hip prosthesis, the press comprising a base having a bracket affixed thereon, the bracket being adapted to receive a shaft having a press bar at its proximal end and a cylinder at its distal end, the cylinder being adapted to press upon a plunger; a femoral cup locator positioned on a base opposing the cylinder; wherein when the femoral cup having a concave surface is positioned in the femoral cup locator with the concave surface in an upwardly directed position and the polymer liner having a concave portion is positioned on the plunger and a convex portion is positioned over the concave portion of the femoral cup, and when the plunger is pushed downwardly using the press bar, the cylinder is caused contact and press down upon the plunger, and the polymer liner is caused to snap into place in the femoral cup.
