Methods and apparatus for FAI surgeries

1. A partial rim implant for an acetabulum in a pelvic bone, wherein the acetabulum comprises an articulating surface, a rim, and an apex, the implant comprising:

a ridge configured to replace a labrum of the acetabulum;

a bearing surface configured to generally align with the articulating surface of the acetabulum, wherein the bearing surface extends from the ridge toward the apex of the acetabulum;

an insertion portion extending away from the bearing surface and adapted to engage a recess in the pelvic bone; and

at least one fixation flange extending from the ridge and away from the bearing surface, wherein the at least one fixation flange is configured for fixation to the pelvic bone to attach the implant to the pelvic bone with the bearing surface of the implant generally aligned with the articulating surface of the acetabulum and the ridge oriented to replace the labrum.

2. The implant of claim 1 , wherein the at least one fixation flange defines at least one fastener opening for receiving a fastener sized and configured to extend into the pelvic bone to attach the implant to the pelvic bone.

3. The implant of claim 2 , wherein the at least one fixation flange defines a plurality of the at least one fastener opening; and

wherein a corresponding one of a plurality of fasteners is positioned within each of the plurality of the at least one fastener opening.

4. The implant of claim 1 , wherein the bearing surface extends between the ridge and the insertion portion.

5. The implant of claim 4 , wherein the bearing surface is curved between the ridge and the insertion portion.

6. The implant of claim 5 , wherein the bearing surface comprises a concave curvature extending between the ridge and the insertion portion.

7. The implant of claim 1 , wherein the insertion portion and the at least one fixation flange each extend away from the bearing surface in the same general direction and define a space therebetween sized and configured for receipt of a portion of the pelvic bone therein.

8. The implant of claim 1 , wherein the at least one fixation flange comprises at least two fixation flanges extending from the ridge and away from the bearing surface, and wherein each of the at least two fixation flanges defines at least one fastener opening for receiving a fastener sized and configured to extend into the pelvic bone to attach the implant to the pelvic bone.

9. The implant of claim 1 , further comprising at least one fastener opening extending through the ridge; and

a fastener positioned within the at least one fastener opening and sized and configured to extend into the pelvic bone to attach the implant to the pelvic bone.

10. The implant of claim 1 , wherein the insertion portion and the at least one fixation flange are angled toward one another as the insertion portion and the at least one fixation flange extend away from the bearing surface.

11. A partial rim implant for an acetabulum in a pelvic bone, wherein the acetabulum comprises an articulating surface, a rim, and an apex, the implant comprising:

a ridge configured to replace a labrum of the acetabulum;

a bearing surface configured to generally align with the articulating surface of the acetabulum, wherein the bearing surface extends from the ridge toward the apex of the acetabulum;

an insertion portion extending away from the bearing surface and adapted to engage a recess in the pelvic bone;

at least one fixation flange extending from the ridge and away from the bearing surface, wherein the at least one fixation flange defines at least one fastener opening; and

a fastener positioned within each of the at least one fastener opening and sized and configured to extend into the pelvic bone to attach the implant to the pelvic bone with the bearing surface of the implant generally aligned with the articulating surface of the acetabulum and the ridge oriented to replace the labrum.

12. The implant of claim 11 , wherein the at least one fixation flange is adapted to lie substantially flush with an outer surface of the pelvic bone.

13. The implant of claim 11 , wherein the bearing surface extends between the ridge and the insertion portion.

14. The implant of claim 13 , wherein the bearing surface is curved between the ridge and the insertion portion.

15. The implant of claim 14 , wherein the bearing surface comprises a concave curvature extending between the ridge and the insertion portion.

16. The implant of claim 11 , wherein the insertion portion and the at least one fixation flange each extend away from the bearing surface in the same general direction and define a space therebetween sized and configured for receipt of a portion of the pelvic bone therein.

17. The implant of claim 11 , wherein the at least one fixation flange comprises at least two fixation flanges extending from the ridge and away from the bearing surface, and wherein each of the at least two fixation flanges defines the at least one of the fastener opening that receives a corresponding one of the fastener.

18. The implant of claim 11 , wherein the at least one fixation flange defines a plurality of the at least one fastener opening; and

wherein a corresponding one of a plurality of the fasteners is positioned within each of the plurality of the at least one fastener opening.

19. The implant of claim 11 , further comprising at least one screw hole extending through the ridge; and

a bone screw positioned within the at least one screw hole and sized and configured to extend into the pelvic bone to further secure the implant to the pelvic bone.

20. The implant of claim 11 , wherein the insertion portion and the at least one fixation flange are angled toward one another as the insertion portion and the at least one fixation flange extend away from the bearing surface.
