Implants, systems and methods of using the same
Implants, device, systems and methods for replacing an articulation surface in a joint, for example, a glenoid implant with an articular surface and an opposing bone contacting surface having a ring and post extending therefrom that respectively mechanically connect with cortical bone and cancellous bone of a glenoid. Methods for implanting the glenoid implant are also disclosed.
1. An implant, comprising:
a first portion having (i) at least one rim positioned on an exterior surface of the first portion, (ii) an articulating surface recessed into a first end of the first portion; and (iii) a bone contacting surface on a second end of the first portion positioned opposite the articulating surface;
a second portion extending away from a bottom surface of the first portion;
a third portion extending away from the bottom surface of the first portion, wherein the third portion extends through the second portion, and wherein the third portion includes at least one thread along a length of the third portion; and
a drive opening extending from the first end through the articulating surface toward the second end of the implant and through at least a portion of the third portion.
2. The implant of claim 1 , wherein the second portion comprises:
a base member extending away from the bone contacting surface of the first portion; and
a recessed region extending through the base member from a second end of the base member to the bone contacting surface of the first portion forming an interior surface.
3. The implant of claim 1 , wherein the drive opening receives a tool.
4. The implant of claim 1 , wherein the at least one rim comprises:
a first rim positioned at the first end of the first portion;
a second rim positioned at the second end of the first portion and spaced apart from the first rim; and
a groove inset into an exterior surface of the first portion and positioned between the first rim and the second rim.
5. The implant of claim 3 , wherein the base member comprises:
an exterior surface.
6. The implant of claim 5 , wherein the base member is threaded around the exterior surface.
7. The implant of claim 6 , wherein the threads of the base member are selected from at least one of right-handed threads and left-handed threads.
8. The implant of claim 5 , wherein the base member includes at least one lip extending away from the exterior surface of the base member.
9. The implant of claim 8 , wherein the at least one lip comprises:
a first lip; and
a second lip positioned at the second end of the base member;
wherein the first lip is positioned between the second lip and the bone contacting surface of the first portion.
10. The implant of claim 1 , wherein the third portion comprises:
a first segment with a first end and a second end, the first end of the first segment coupled to and extending away from the bottom surface of the first portion toward the second end of the implant; and
a second segment coupled to and extending away from the second end of the first segment.
11. The implant of claim 10 , wherein the first segment has a first thread and the second segment has a second thread.
12. The implant of claim 10 , wherein the first segment has a first diameter and a first length, wherein the second segment has a second diameter and a second length, wherein the first diameter is larger than the second diameter, and wherein the first length is smaller than the second length.
13. The implant of claim 10 , wherein the first segment includes at least a portion that is non-threaded.
14. The implant of claim 10 , wherein the first segment comprises a textured surface.
15. The implant of claim 6 , wherein the second portion further comprises:
a plurality of tabs extending away from the base member forming gaps in the threads.
16. The implant of claim 2 , wherein the plurality of tabs are spaced around an exterior surface of the base member.
