Abstract

Combination apparatus for a total hip replacement or compression and fixation of the femoral head to a femur is provided. A compression plate is provided with a strut member extending between the barrel of the plate and the lower portion of the plate to significantly reinforce the connection of the barrel to the plate. The barrel is alternatively utilized with a compression screw apparatus or total hip replacement apparatus.

Claims

1. Combination hip compression screw and total hip replacement apparatus adapted to be secured to a person'"'"'s femur comprising:

an elongated plate having a barrel member attached at one end of said plate and extending cantileverly therefrom;

said plate including means for attaching said plate to said femur; and

a brace for structurally supporting the cantilever attachment of said barrel to said plate said brace having a first end fixedly attached to said plate and a second end disengaged from, and in supporting contact to said extending barrel member.

2. The apparatus of claim 1, wherein said brace means comprises an elongated rod extending at an angle from said plate attached at one end to said plate and in supporting contact at a second end with the extending end of said barrel.

3. The apparatus of claim 1, including a lag screw fitted within an opening through said barrel and said plate.

4. The apparatus of claim 3, including screw means for axially securing said lag screw within said opening in said barrel and plate.

5. The apparatus of claim 1, including a shank member fitted within said barrel, and a femoral head replacement member rotatingly attached to said shank member.

6. The apparatus of claim 5, including screw means for axially securing said shank member within said barrel.

7. The apparatus of claim 1, including a backing member attached to said plate, said backing member having one or more holes thereacross the width thereof.

8. The apparatus of claim 7, adapted to be attached to a femur, further comprising a wire threaded through said one or more holes thereacross and secured to said femur.

9. The apparatus of claim 1, wherein said plate includes a plurality of axially spaced slots therethrough.
