Patent Images
1. A sternum fixation device for securing parts of a sternum comprising:
- a first plate having an upper surface and a sternum-contacting surface, and a first attachment member for fixation to the sternum;
a second plate having an upper surface and a sternum-contacting surface, and a second attachment member for fixation to the sternum;
a release member for holding the first and second plates together, wherein the removal of the release member from the first and second longitudinal bores allows separation of the parts of the sternum;
wherein the first and second plates each have at least one series of ratcheting teeth, such that the distance between the first and second plates may be incrementally varied.

Abstract
A sternum fixation device for securing parts of a sternum includes first and second removably associated plates. The first plate has an upper surface and a sternum-contacting surface, and at least one hole passing through both of these surfaces for receiving a fastener head. The second plate has at least one attachment member for fixation to the sternum. A release member holds the first and second plates together, and is movably associated with at least one of the first and second plates such that it may be moved to allow separation of the two parts of the sternum.
