Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
123 words
An endoprosthetic bone clip for joining bones in vivo under a selected compressive force, comprising: an elongated metallic body member having coplanar, unilaterally extending single legs at each longitudinal end thereof; said legs being formed unitarily with and extending substantially perpendicular to said body member; said legs being adapted for insertion into respective predrilled holes in said bones joined; and including single wire means overlying said body member and having each end portion thereof extending through said body member adjacent the ends thereof so as to secure the ends of said wire means to a respective remote end of each of said legs for drawing the remote ends of said legs towards each other, imparting said selected force, and thereby joining said bones.
