Abstract

An implant for bone fixation is presented. The implant comprises an elongated member configured to be wound around bone parts that are to be fixed. Further, an engagement feature is provided that is coupled to the elongated member and configured to engage a portion of the elongated member so as to secure the implant in a loop around the bone parts. A fastening member is arranged between and coupled to the elongated member and the engagement member. The fastening member comprises at least one opening for receiving a bone fastener. In one variant, at least one visual indicator indicating a region of the fastening member to be severed in order to detach the implant is provided. In another variant, at least one of the engagement member and the elongated member are coupled to the fastening member by injection molding.

Claims (30)

1. An implant for bone fixation, comprising:

an elongated member defining a width between a first lateral side of the elongated member and a second lateral side of the elongated member, the elongated member being configured to be wound around bone portions that are to be fixed;

an engagement member coupled to the elongated member and configured to engage a portion of the elongated member so as to secure the implant in a loop around the bone portions; and

a fastening member arranged between and coupled to the elongated member and the engagement member, the fastening member comprising at least one opening for receiving a bone fastener and a region configured to be severed in order to open the loop of the implant, the fastening member being coupled to at least one of the elongated member and the engagement member by injection molding,

wherein a portion of the region configured to be severed is located between a first axis collinear with the first lateral side and a second axis collinear with the second lateral side.

2. The implant of claim 1 , wherein the region configured to be severed is a region of reduced mechanical strength of the fastening member.

3. The implant of claim 1 , wherein the fastening member comprises a first end and a second end opposite to the first end, wherein the elongated member is injection molded to the first end of the fastening member and/or the engagement member is injection molded to the second end of the fastening member.

4. The implant of claim 3 , wherein the elongated member is injection molded to the first end of the fastening member in a first injection molding process and wherein the engagement member is injection molded to the second end of the fastening member in a second injection molding process separate from the first injection molding process.

5. The implant of claim 1 , wherein the region configured to be severed is defined by a portion of the fastening member that remains exposed from injection molding.

6. The implant of claim 1 , wherein the region configured to be severed includes a visual indicator that extends in a direction substantially perpendicular to an extension of the elongated member.

7. The implant of claim 1 , wherein the fastening member comprises at least a first opening and a second opening that are substantially aligned with an extension of the elongated member, and wherein the region configured to be severed is located between the first opening and the second opening.

8. The implant of claim 7 , wherein the first opening is configured to be located proximate to a first bone portion and the second opening is configured to be located proximate to a second bone portion to be fixed.

9. An implant for bone fixation, comprising:

an elongated member defining a width between a first lateral side of the elongated member and a second lateral side of the elongated member, the elongated member being configured to be wound around bone portions that are to be fixed;

an engagement member coupled to the elongated member and configured to engage a portion of the elongated member so as to secure the implant in a loop around the bone portions;

a fastening member arranged between and coupled to the elongated member and the engagement member, the fastening member comprising at least one opening for receiving a bone fastener and at least one visual indicator having a region of reduced mechanical strength located between a first axis collinear with the first lateral side and a second axis collinear with the second lateral side, the at least one visual indicator indicating a region of the fastening member to be severed in order to open the loop of the implant, the fastening member being coupled to at least one of the elongated member and the engagement member by injection molding,

wherein the positioning of the implant around the bone portions locates the at least one visual indicator about a junction of the bone portions such that severing the at least one visual indicator opens the loop of the implant adjacent the junction of the bone portions.

10. The implant of claim 9 , wherein the fastening member comprises a first end and a second end opposite to the first end, wherein the elongated member is injection molded to the first end of the fastening member and/or the engagement member is injection molded to the second end of the fastening member.

11. The implant of claim 9 , wherein the elongated member comprises a plurality of engagement features provided along an extension of the elongated member, wherein the engagement member is configured to be brought into selective engagement with one of the engagement features.

12. The implant of claim 9 , further comprising a hook member coupled to the elongated member at an end thereof opposite to the engagement member.

13. The implant of claim 12 , wherein the hook member is coupled to the elongated member by injection molding.

14. The implant of claim 9 , wherein the at least one opening of the fastening member comprises a locking feature configured to lock the bone fastener to the fastening member.

15. The implant of claim 9 , wherein the fastening member is made from metallic material and the elongated member is made from a polymeric material.

16. A system for bone fixation, comprising:

an implant comprising:

an elongated member defining a width between a first lateral side of the elongated member and a second lateral side of the elongated member, the elongated member being configured to be wound around bone portions that are to be fixed;

an engagement member coupled to the elongated member and configured to engage a portion of the elongated member so as to secure the implant in a loop around the bone portions; and

a fastening member arranged between and coupled to the elongated member and the engagement member, the fastening member comprising at least one opening for receiving a bone fastener and a region configured to be severed in order to open the loop of the implant, wherein the region configured to be severed is a region of reduced mechanical strength and is located between a first axis collinear with the first lateral side and a second axis collinear with the second lateral side, and wherein the fastening member is coupled to at least one of the elongated member and the engagement member by injection molding; and

at least one bone fastener configured to be inserted through the at least one opening of the fastening member of the implant into bone.

17. The system of claim 16 , wherein the at least one opening of the fastening member comprises a first locking feature configured to lock the bone fastener to the fastening member and wherein the bone fastener comprises a second locking feature configured to engage the first locking feature.
