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 at least one hole passing through the upper and sternum-contacting surfaces for receiving a fastener head, the first plate further including a first longitudinal bore defining an axis oriented substantially transversely to the at least one hole;
a second plate having an upper surface and a sternum-contacting surface, and an attachment member for fixation to the sternum, the second plate further including a second longitudinal bore; and
a release member for holding the first and second plates together, wherein the first and second plates are dimensioned to mate with one another such that the first and second longitudinal bores are aligned to receive the release member, and removal of the release member from the first and second longitudinal bores allows separation of the parts of the sternum.

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.
