Abstract

A bone plate system is designed for use on a bone, which may be a humerus. The system includes an elongated bone plate extending along a longitudinal axis, the bone plate having an upper surface, an opposed bone-facing surface, and a boundary edge of the bone plate; and at least one threaded fastener hole extending from the upper surface to the bone-facing surface. The fastener holes are designed to receive a bone fastener to couple the bone plate to the bone. A plurality of first suture-receiving structures are connected with the bone plate and project from the boundary edge of the bone plate, so that the first suture-receiving structures are spaced from each another along the boundary edge of the bone plate. Each of the first suture-receiving structures comprises a wire loop anchored to the upper surface or to the bone-facing surface of the bone plate.

First claim

What is claimed is:

1. A bone plate system for use on a bone, the system comprising:
an elongated bone plate extending along a longitudinal axis, the bone plate having an upper surface, an opposed bone-facing surface, and a boundary edge surface of the bone plate, wherein the boundary edge surface connects the upper surface to the opposed bone-facing surface;
at least one fastener hole extending from the upper surface to the bone-facing surface, the at least one fastener hole being configured to receive a bone fastener configured to couple the bone plate to the bone;
a plurality of first suture-receiving structures connected with the bone plate and projecting from the boundary edge surface of the bone plate, the first suture-receiving structures being spaced from each another along the boundary edge surface; and
a second suture-receiving structure comprising a suture-receiving hole with a lower surface, the lower surface of the suture-receiving hole extending from the upper surface of the bone plate to the boundary edge surface of the bone plate without intersecting the bone-facing surface of the bone plate;
wherein each of the plurality of first suture-receiving structures comprises a wire loop, wherein each wire loop is anchored to the upper surface or the bone-facing surface of the bone plate without engaging the suture receiving hole of the second suture-receiving structure.

2. The bone plate system of claim 1 , wherein:
the bone is a humerus;
the boundary edge surface of the bone plate has two opposing side edges and an end edge; and
at least one of the plurality of first suture-receiving structures projects from each opposing side edge of the boundary edge surface, and is configured to receive a suture connecting the elongated bone plate to at least one of an infraspinatus tendon, a teres minor tendon, or a subscapularis tendon.

3. The bone plate system of claim 1 , wherein:
the first suture-receiving structures are formed from a single wire; and
the single wire has two ends anchored in wire-receiving holes formed into the plate surface, which may or may not extend to the opposed bone-facing surface.

4. The bone plate system of claim 3 , wherein:
the opposed bone-facing surface has wire-receiving troughs formed therein;
at least a portion of the length of the single wire is positioned within the wire-receiving troughs; and
the troughs are configured to prevent movement of the single wire relative to the opposed bone-facing surface.

5. The bone plate system of claim 1 , wherein:
the bone is a humerus;
the boundary edge surface of the bone plate has two opposing side edges and an end edge; and
at least one of the plurality of first suture-receiving structures projects from the end edge of the boundary edge surface, and is configured to receive a suture connecting the elongated bone plate to a supraspinatus tendon.

6. The bone plate system of claim 5 , wherein:
the first suture-receiving structures are formed from a single wire; and
the single wire has two ends anchored in wire-receiving holes formed on the opposed bone-facing surface.

7. The bone plate system of claim 6 , wherein:
the opposed bone-facing surface has wire-receiving troughs formed therein;
at least a portion of the length of the single wire is positioned within the wire-receiving troughs; and
the troughs are configured to prevent movement of the single wire relative to the opposed bone-facing surface.

8. The bone plate system of claim 5 , wherein:
the elongated bone plate has an indented surface on the upper surface of the bone plate near the end edge;
the first suture-receiving structures projecting from the end edge are formed from a single wire connected to the indented surface; and
the single wire has two ends anchored in wire-receiving holes formed on the indented surface of the bone plate.

9. The bone plate system of claim 8 , further comprising:
at least one third suture-receiving structure, wherein the at least one third suture-receiving structure projects from the boundary edge surface of the bone plate,
wherein the at least one third suture-receiving structure is formed from a second single wire; and
the second single wire has two ends anchored in wire-receiving holes formed on the opposed bone-facing surface.

10. The bone plate system of claim 9 , wherein:
the opposed bone-facing surface has wire-receiving troughs formed therein;
at least a portion of the length of the second single wire is positioned within the wire-receiving troughs; and
the troughs are configured to prevent movement of the second single wire relative to the opposed bone-facing surface.

11. The bone plate system of claim 1 , wherein:
the boundary edge surface of the bone plate has two opposing side edges and an end edge at least one of the plurality of first suture-receiving structures projects from each opposing side edge of the boundary edge surface, and
at least one of the plurality of first suture-receiving structures projects from the end edge of the boundary edge surface.

12. The bone plate system of claim 11 , wherein:
wherein the first suture-receiving structures projecting from the side edge and the first suture-receiving structures projecting from the end edge are formed from a single wire;
wherein the single wire has two ends anchored in wire-receiving holes formed on the opposed bone-facing surface.

13. The bone plate system of claim 12 , wherein:
the opposed bone-facing surface has wire-receiving troughs formed therein;
at least a portion of the length of the single wire is positioned within the wire-receiving troughs; and
the troughs are configured to prevent movement of the second single wire relative to the opposed bone-facing surface.

14. The bone plate system of claim 1 , further comprising:
at least one third suture-receiving structure connected with the bone plate;
wherein each third suture-receiving structure comprises a threaded hole; a screw with a threaded shaft, and a washer configured to engage the threaded shaft;
wherein the threaded shaft is configured to be wrapped with a suture; and
wherein the screw is configured to be screwed into the threaded hole until the suture is compressed between the upper surface of the bone plate and the washer.

15. The bone plate system of claim 1 , further comprising:
at least one third suture-receiving structure connected with the bone plate;
wherein each third suture-receiving structure comprises an indented surface in the upper surface of the bone plate and a cleat mounted on the indented surface;
each cleat comprising a post mounted on the indented surface, the post having a first cross-sectional area; and a head mounted on the post, the head having an upper surface with a second area which is larger than the first cross-sectional area.

16. The bone plate system of claim 1 , wherein each wire loop is anchored to the bone-facing surface of the bone plate.

17. A bone plate system for use on a bone, the system comprising:
an elongated bone plate extending along a longitudinal axis, the bone plate having an upper surface, an opposed bone-facing surface, and a boundary edge surface of the bone plate, wherein the boundary edge surface connects the upper surface to the opposed bone-facing surface;
at least one fastener hole extending from the upper surface to the bone-facing surface, the at least one fastener hole being configured to receive a bone fastener configured to couple the bone plate to the bone; and
at least one first suture-receiving structure in the bone plate;
wherein each first
