The toe bone implant also includes a second portion having a ball portion operatively connected to the socket portion. The toe bone implant is implanted in a joint such that the ball portion is configured to rotate a predetermined amount respective to the socket portion.
1. A toe bone implant, comprising:
a first portion comprising a socket portion;
a second portion comprising a ball portion operatively connected to the socket portion; and a resorbable portion operatively connected to the first and second portions and configured to limit rotation of the ball portion respective to the socket portion for a predetermined period of time of approximately 8 to 12 weeks and when the implant is implanted in a joint.
2. The bone implant of claim 1 , wherein the resorbable portion is selected from the group consisting of a resorbable pin, a resorbable bridge, a resorbable lock out device, and a resorbable snap-on device.
3. The bone implant of claim 1 , wherein the ball portion is configured to rotate a predetermined amount in a longitudinal direction.
4. The bone implant of claim 1 , wherein the ball portion is configured to rotate a predetermined amount in a lateral direction.
5. The bone implant of claim 1 , wherein the ball portion is configured to freely rotate about an axis of rotation.
6. The bone implant of claim 1 , wherein the joint is a proximal interphalangeal (PIP) joint.
7. The bone implant of claim 1 , wherein the joint is a metatarsal phalangeal joint.
8. The bone implant of claim 1 , wherein one or more of the first or second portions comprises a threaded edge portion.
9. The bone implant of claim 1 , wherein one or more of the first or second portions comprises an edge portion comprising blades.
10. A toe bone implant, comprising:
a first portion comprising a socket portion;
a second portion comprising a ball portion operatively connected to the socket portion such that the ball portion is configured to rotate a predetermined amount respective to the socket portion; and
a resorbable portion operatively connected to the first and second portions and configured to limit rotation of the ball portion respective to the socket portion for a predetermined period of time.
11. The bone implant of claim 10 , wherein the ball portion is configured to rotate a predetermined amount in a longitudinal direction.
12. The bone implant of claim 10 , wherein the ball portion is configured to rotate a predetermined amount in a lateral direction.
13. The bone implant of claim 10 , wherein the ball portion is configured to freely rotate about an axis of rotation.
14. The bone implant of claim 10 , wherein the joint is a proximal interphalangeal (PIP) joint.
15. The bone implant of claim 10 , wherein the joint is a metatarsal phalangeal joint.
16. The bone implant of claim 10 , wherein one or more of the first or second portions comprises a threaded edge portion.
17. The bone implant of claim 10 , wherein one or more of the first or second portions comprises an edge portion comprising blades.
18. A toe bone implant, comprising:
a first portion comprising a socket portion;
a second portion comprising a ball portion operatively connected to the socket portion such that the ball portion is configured to rotate a predetermined amount respective to the socket portion; and
a resorbable portion selected from the group consisting of a resorbable pin, a resorbable bridge, a resorbable lock out device, and a resorbable snap-on device is operatively connected to the first and second portions and configured to limit rotation of the ball portion respective to the socket portion for a predetermined period of time.
