Moveable bone plate implantation system and method of use
The present invention discloses a moveable bone plate implantation system, controlled movement assembly, and method. The moveable bone plate implantation system includes a movement instrument, translation member removeably coupled to the movement instrument, and a bone plate detachably connected to the translation member. The controlled movement assembly includes a translation member and a bone plate. The translation member includes a shaft with a first end and a second end and a head portion at the first end. The head portion includes an engagement groove recessed into the head portion and a lip extending out from a bottom portion of the engagement groove. The bone plate includes an engagement aperture for receiving the engagement groove and the lip engages a bottom surface of the bone plate during translation of the bone plate. A method for moving bones is also disclosed.
1. A method for moving at least one bone, comprising:
preparing the at least one bone;
obtaining a moveable bone plate implantation system;
aligning a bone plate on the at least one bone;
inserting a first fastener through the bone plate and into a first bone of the at least one bone;
aligning a translation member with an engagement aperture in the bone plate;
sliding a first alignment guide of a movement instrument over the translation member and coupling the translation member to the first alignment guide;
inserting a temporary fixation pin through a second alignment guide of the movement instrument to engage a second bone and coupling the temporary fixation pin to the second alignment guide;
translating a moveable member of the movement instrument with respect to an extension member of the movement instrument.
2. The method of claim 1 , wherein translating the moveable member comprises:
rotating a movement mechanism of the movement instrument to translate the moveable member with respect to the extension member.
3. The method of claim 2 , wherein translating the moveable member compresses the first bone and the second bone.
4. The method of claim 2 , wherein translating the moveable member distracts the first bone and the second bone.
5. The method of claim 2 , wherein rotating the movement mechanism moves the moveable member along a base member of the movement instrument.
6. The method of claim 1 , further comprising:
inserting a second fastener into the second bone through the bone plate.
7. The method of claim 6 , further comprising:
removing the temporary fixation pin, the movement instrument, and the translation member.
8. The method of claim 7 , further comprising:
closing an incision in a patient.
9. The method of claim 1 , wherein the moveable bone plate implantation system comprises:
the movement instrument;
the translation member shaped to couple to the movement instrument; and
the bone plate with the engagement aperture for receiving the translation member.
10. The method of claim 1 , further comprising:
inserting a temporary fixation pin through the bone plate and into the second bone before aligning the translation member with the engagement aperture in the bone plate.
11. The method of claim 1 , wherein aligning a translation member with the engagement aperture in the bone plate comprises:
mating an engagement groove of the translation member with the engagement aperture of the bone plate.
12. The method of claim 11 , wherein the engagement groove is positioned at a first end of the engagement aperture to compress the first bone and the second bone.
13. The method of claim 11 , wherein the engagement groove is positioned at a second end of the engagement aperture to distract the first bone and the second bone.
14. The method of claim 11 , wherein mating an engagement groove with the engagement aperture of the bone plate, further comprises:
engaging at least one lip surrounding the engagement groove with at least one of a top surface or a bottom surface of the bone plate.
15. The method of claim 1 , wherein the at least one bone is at least one bone of a foot.
16. The method of claim 1 , wherein the first bone is a first piece of a single bone, and wherein the second bone is a second piece of the single bone.
17. The method of claim 1 , wherein the moveable member includes a through hole for receiving the second alignment guide.
18. The method of claim 1 , wherein the extension member includes a through hole for receiving the first alignment guide.
19. The method of claim 1 , wherein the first fastener is selected from a locking screw and a non-locking screw.
20. The method of claim 6 , wherein the second fastener is selected from a locking screw and a non-locking screw.
