Abstract

The present invention discloses an orthopedic bone plate and locking tab apparatus and method of use. The orthopedic plate includes a body with a first end, a second end, and a central portion extending between the first end and the second end, a first pair of lobes at the first end, a second pair of lobes at the second end, and a securing mechanism extending away from a bottom surface of the central portion. The securing mechanism includes a base portion projecting from the body portion of the bone plate and two opposing extension members projecting from the base portion. A method for inserting the bone plate is also disclosed.

First claim

Having thus described the preferred embodiments, the invention is now claimed to be:

1. An orthopedic plate, comprising:
a body with a first end, a second end, and a central portion extending between the first end and the second end;
a first pair of lobes at the first end;
a second pair of lobes at the second end; and
a securing mechanism extending away from a bottom surface of the central portion, wherein the securing mechanism comprises:
a base portion extending between a medial side and a lateral side of the body, the base portion including a proximal end coupled to the body and a distal end; and
at least two opposing extension members projecting from the distal end of the base portion;
wherein each of the two opposing extension members comprise at least two retaining members, the at least two retaining members are positioned along an end of each of the two opposing extension members, and wherein a first retaining member of the at least two retaining members extends away from the extension members toward the first end of the body and a second retaining member of the at least two retaining members extends away from the extension members toward the second end of the body.

2. The orthopedic plate of claim 1 , wherein the
base portion is monolithic.

3. The orthopedic plate of claim 2 , wherein the securing mechanism further comprises:
a cavity positioned between the at least two opposing extension members.

4. The orthopedic plate of claim 3 , wherein the at least two opposing extension members further comprise an insertion end positioned at an end of each of the at least two retaining members opposite the base portion, and wherein the insertion ends are blunt.

5. The orthopedic plate of claim 4 , wherein the at least two opposing extension members are tapered from the at least two retaining members to the insertion end.

6. The orthopedic plate of claim 5 , wherein the at least two opposing extension members are tapered in a proximal-distal direction from the distal end of the base portion to the insertion end, and wherein the base portion and the at least two opposing extension members are tapered in a medial-lateral direction from a bottom surface of the body to the insertion ends of the at least two opposing extension members.

7. The orthopaedic plate of claim 3 , wherein the cavity is curved between the two opposing extension members.

8. The orthopedic plate of claim 1 , further comprising:
at least one hole in the first end of the body; and
at least one hole in the second end of the body.

9. The orthopedic plate of claim 8 , wherein the at least one hole in the first end comprises at least one hole in the first pair of lobes and the at least one hole in the second end comprises at least one hole in the second pair of lobes.

10. The orthopedic plate of claim 9 , wherein each of the lobes in the second pair of lobes includes at least one hole and each of the at least one holes is angled toward the securing mechanism.

11. The orthopedic plate of claim 1 , wherein the first pair of lobes includes a first lobe offset from a second lobe and the second pair of lobes includes a first lobe oriented parallel to a second lobe.

12. The orthopedic plate of claim 1 , wherein the body has a longitudinal curvature from the first end to the second end.

13. The orthopedic plate of claim 12 , wherein the body has a diametral curvature from the medial side to the lateral side.

14. A bone plate securing mechanism, wherein the securing mechanism is coupled to a bone plate and includes a body portion comprising:
a base portion projecting from the body portion of the bone plate and extending between a medial side and a lateral side of the body portion of the bone plate, wherein the base portion is continuous between the medial side and the lateral side; and
two opposing extension members projecting from a distal end of the base portion, wherein each of the two opposing extension members comprise:
at least two shoulder portions positioned along an end of the two opposing extension members, wherein a first shoulder portion of the at least two shoulder portions projects in a first direction, and wherein a second shoulder portion of the at least two shoulder portions projects in a second direction; and
an insertion end positioned at a distal end of each of the two opposing extension members.

15. The bone plate securing mechanism of claim 14 , wherein a cavity is defined by the two opposing extension members, and wherein a bottom portion of the cavity is curved between the two opposing extension members.

16. The bone plate securing mechanism of claim 15 , wherein the insertion end of the two opposing extension members is rounded.

17. The bone plate securing mechanism of claim 16 , wherein the at least two opposing extension members are angled from the at least two retaining members to the insertion end.

18. The bone plate securing mechanism of claim 17 , wherein the at least two opposing extension members are angled in a proximal-distal direction from the distal end of the base portion to the insertion end, and wherein the base portion and the at least two opposing extension members are tapered in a medial-lateral direction from a proximal end of the base portion to the insertion ends of the at least two opposing extension members.
