Patent Images
1. A surgical fastener device for use in bone fracture fixation, said device comprising:
- a top block portion having bore means extending therethrough, an uppermost top surface, and four side surfaces depending from edges of said top surface; and
a protrusion integral with and extending from an underside of said top block portion centrally lengthwise and widthwise of said top block portion, said underside being bounded by said four side surfaces; and
said top block side surfaces defining the lateral extent of said device.

Abstract
A surgical fastener for use in bone fracture fixation comprises a top block portion having a bore extending therethrough and adapted to receive surgical cable, and a protrusion extending from an underside of the top block portion and centrally of the top block portion, and adapted for insertion into a compression plate recess which prevents sliding of the fastener along the bone during tightening of the cable around the bone fracture area.

- 9. A surgical fastener device for use in bone fracture fixation, said device comprising a block having a bore extending therethrough, said block having a flat, upper most top surface and four side walls depending from edges of said to surface, and an undersurface with gripper means extending from said undersurface for direct engagement with a bone surface, said gripper means being disposed wholly within hypothetical extensions of said side walls, and comprising bone surface penetrating means.

13. A method for binding together first and second bone portions, the method comprising the steps of:
-
providing a fastener device having a top block portion with bore means extending therethrough, an uppermost top surface, and four side surfaces depending from edges of said top surface, and a protrusion integral with and extending from an underside of said top block portion centrally of said top block portion, said underside being bounded by said four side surfaces, and said top block side surfaces defining the lateral extent of said device; providing a compression plate having a recess therein and a screw hole in said recess and extending through said plate; providing a surgical cable; placing said bone portions in position for binding together; and placing said plate alongside said bone portions and abutting said bone portions, and placing said protrusion in said plate recess and screw hole, and encircling said bone portions with said cable, extending said cable through said bore means, pulling said cable taut, and fixing said cable in said fastener device.

14. A method for binding together first and second bone portions, the method comprising the steps of:
-
providing a fastener device comprising a block with bore means extending therethrough, said block having a flat, upper most top surface and four side walls depending from edges of said top surface, and an undersurface with gripper means extending from said underside for direct engagement with a surface of one of said bone portions, said gripper means being disposed wholly within hypothetical extensions of said side walls, and comprising bone surface penetrating means; providing a surgical cable; placing said bone portions in position for binding together; and placing said device undersurface in engagement with said surface of said one bone portion, and encircling said bone portions with said cable, extending said cable through said bore means, pulling said cable taut, and fixing said cable in said fastener device.
