Abstract

An orthopedic system according to one embodiment of the disclosure comprises a first trial member capable of forming a broach cavity in a first bone of a patient. A second trial member is removeably coupleable to the first trial member in a fixed alignment with respect to the trial member. An alignment member is removeably coupleable in a fixed alignment with respect to the first trial member. The alignment member comprises indicia configured to provide for alignment of the alignment member with respect to at least one of the first bone and a second bone of the patient. The alignment of the second trial member with respect to the first trial member when coupled to the first trial member corresponds to the alignment of the alignment member with respect to the first trial member when coupled with the first trial member.

Claims (31)

1. An orthopedic system comprising:

a first trial member capable of forming a broach cavity in a first bone of a patient, the first trial member having an outer surface comprising a surface feature for broaching the first bone;

a second trial member removeably coupleable to the first trial member in a fixed alignment with respect to the first trial member; and

an alignment member removeably coupleable in a fixed alignment with respect to the first trial member, the alignment member comprising indicia configured to provide for alignment of the alignment member with respect to at least one of the first bone of the patient and a second bone of the patient;

wherein the alignment of the second trial member with respect to the first trial member when coupled to the first trial member corresponds to the alignment of the alignment member with respect to the first trial member when coupled with the first trial member.

2. The orthopedic system of claim 1 , wherein the first trial member and the alignment member are each configured so that the first trial member and the alignment member are in desired alignment with respect to each other when the alignment member is coupled to the first trial member.

3. The orthopedic system of claim 1 , wherein the alignment member has a geometry that is substantially similar to a geometry of the second trial member.

4. The orthopedic system of claim 1 , wherein the alignment of the second trial member with respect to the first trial member when coupled to the first trial member is substantially the same as the alignment of the alignment member with respect to the first trial member when coupled with the first trial member.

5. The orthopedic system of claim 1 , comprising a handle removeably coupleable to at least one of the first trial member and the second trial member.

6. The orthopedic system of claim 5 , wherein the alignment member is removeably coupleable to the handle.

7. The orthopedic system of claim 1 , wherein the first trial member comprises a trial conical augment for inserting within a tibia of the patient and the second trial member comprises a trial base plate of a tibial component of an artificial knee implant trial.

8. An orthopedic system comprising:

a first trial member capable of forming a broach cavity in a first bone of a patient, the first trial member having an outer surface comprising a surface feature for broaching the first bone;

an alignment member for aligning the first trial member with respect to at least one of the first bone of the patient and a second bone of the patient; and

a second trial member removeably coupleable to the first trial member in a fixed alignment with respect to the first trial member;

wherein the fixed alignment of the second trial member with respect to the first trial member when coupled to the first trial member corresponds to the alignment of the alignment member with respect to the first trial member when coupled with the first trial member.

9. The orthopedic system of claim 8 , wherein the first trial member and the alignment member are each configured so that the first trial member and the alignment member are in desired alignment with respect to each other when the alignment member is coupled to the first trial member.

10. The orthopedic system of claim 8 , wherein the alignment member has a geometry that is substantially similar to a geometry of the second trial member.

11. The orthopedic system of claim 8 , wherein the alignment of the second trial member with respect to the first trial member when coupled to the first trial member is substantially the same as the alignment of the alignment member with respect to the first trial member when coupled with the first trial member.

12. The orthopedic system of claim 8 , comprising a handle removeably coupleable to at least one of the first trial member and the second trial member.

13. The orthopedic system of claim 12 , wherein the alignment member is removeably coupleable to the handle.

14. The orthopedic system of claim 8 , wherein the first trial member comprises a trial conical augment for inserting within a tibia of the patient and the second trial member comprises a trial base plate of a tibial component of an artificial knee implant trial.

15. A method comprising:

aligning a first trial member with respect to at least one of a first bone of a patient and a second bone of the patient;

broaching the first bone with the first trial member, the first trial member having an outer surface comprising a surface feature for broaching the first bone; and

coupling a second trial member to the first trial member so that an alignment of the second trial member with respect to the first trial member corresponds to the alignment of the first trial member with respect to the at least one of the first bone and the second bone.

16. The method of claim 15 , wherein aligning the first member with respect to the at least one of the first bone and the second bone comprises coupling an alignment member to the first trial member and aligning the alignment member with respect to the at least one of the first bone and the second bone.

17. The method of claim 16 , wherein the first trial member and the alignment member are each configured so that the first trial member and the alignment member are in desired alignment with respect to each other when the alignment member is coupled to the first trial member.

18. The method of claim 16 , wherein the alignment member comprises indicia that assist a user in aligning the alignment member with respect to the at least one of the first bone and the second bone.

19. The method of claim 16 , wherein the alignment member has a geometry that is substantially similar to a geometry of the second trial member.

20. The method of claim 16 , comprising decoupling the alignment member from the first trial member before coupling the second trial member to the first trial member.
