Abstract

An implantable apparatus (10) for attaching bone fragments in a bone fracture reduction procedure comprises a bone affixation plate (12) and a polymeric applicator (18) having a deflectable portion (22) that is deflectable to engage a portion (16) of the plate to attach the applicator to the plate. The applicator (18) is thereafter deflectable to disengage from the portion (16) of the plate (12) to remove the applicator from the plate. The applicator (18), when attached to the plate (12), enables the plate to be handled and manipulated during the bone fracture reduction procedure. The applicator (18) may includes means (24) for identifying the plate (12).

Claims

1. An implantable apparatus for attaching bone fragments in a bone fracture reduction procedure, said apparatus comprising:

a bone affixation plate; and

a polymeric applicator having a deflectable portion that is deflectable to engage a portion of said plate to attach said applicator to said plate and is thereafter deflectable to disengage from said portion of said plate to remove said applicator from said plate;

said applicator, when attached to said plate, enabling said plate to be handled and manipulated during the bone fracture reduction procedure.

2. The apparatus of claim 1 wherein said applicator further including means for identifying said plate.

3. The apparatus of claim 1 wherein said deflectable portion of said applicator attaches to said plate with a snap fit.

4. The apparatus of claim 1 wherein removal of said applicator from said plate leaves no residue of said applicator on said plate.

5. The apparatus of claim 1 wherein said deflectable portion includes first and second legs that together form a receptacle for receiving said portion of said plate, said first and second legs extending from a main body portion of said applicator and being resiliently deflectable away from one another.

6. The apparatus of claim 5 wherein said first leg includes a first groove and said second leg includes a second groove, said portion of said plate seating in said first and second grooves when said applicator is attached to said plate.

7. The apparatus of claim 5 wherein said first and second legs are separated by an axially extending slot, said axially extending slot enabling said first and second legs to deflect away from one another.

8. An implantable apparatus for attaching bone fragments in a bone fracture reduction procedure, said apparatus comprising:

a thin malleable bone affixation plate formed of a biocompatible material, said plate having at least two openings extending through said plate, each of said at least two openings for receiving a bone screw to be driven into a bone fragment to affix said plate to the bone fragment; and

a polymeric applicator having a deflectable portion that is deflectable for receiving a portion of said plate to attach said applicator to said plate and is thereafter deflectable to release said portion of said plate to remove said applicator from said plate, when attached to said plate said applicator enabling said plate to be handled and manipulated during the bone fracture reduction procedure;

said applicator further including means for identifying said plate.

9. The apparatus of claim 8 wherein said deflectable portion of said applicator attaches to said plate with a snap fit.

10. The apparatus of claim 8 wherein removal of said applicator from said plate leaves no residue of said applicator on said plate.

11. The apparatus of claim 8 wherein said deflectable portion includes first and second legs that together form a receptacle for receiving said portion of said plate, said first and second legs extending from a main body portion of said applicator and being resiliently deflectable away from one another.

12. The apparatus of claim 11 wherein said first leg includes a first groove and said second leg includes a second groove, said portion of said plate seating in said first and second grooves when said applicator is attached to said plate.

13. The apparatus of claim 11 wherein said first and second legs are separated by an axially extending slot, said axially extending slot enabling said first and second legs to deflect away from one another.
