Abstract
The present disclosure relates to an implantable split sternum prosthesis to facilitate closure of the chest cavity and relieve pain after sternotomy operations. The split sternum prosthesis which after a surgical procedure is placed along the inline incision made in the sternum bone will also facilitate access to the chest cavity for patients in need of repeated surgical operations inside the chest cavity. The split sternum prosthesis comprises two elongated bone attachment plates, a first bone attachment plate and a second bone attachment plate. The first and he second bone attachment plates each have a bone attachment surface and a coupling surface. The first and second bone attachment plates are adapted be coupled together in a very close fit along their coupling surfaces.

A split sternum prosthesis configured for use after a sternum has been subjected to median sternotomy, during which the sternum is divided into a first and a second sternum half, each sternum half having an anterior surface, a posterior surface and an incision surface;
- said incision surface extending in a vertical direction z between said anterior surface and said posterior surface;
- said split sternum prosthesis comprising a first bone attachment plate and a second bone attachment plate, each of the first and second bone attachment plates having a longitudinal extension x configured to correspond to at least part of a length of the sternum, a transverse extension y configured to correspond to at least part of a width of a sternum half, and a vertical extension z configured to correspond to a thickness of the sternum, characterized in that:
- the first and the second bone attachment plates each have at least one bone attachment surface, wherein the at least one bone attachment surface of each of the first and second bone attachment plates comprises a first portion that is configured to cover at least a portion of the incision surface of a respective sternum half, a second portion that is configured to cover at least part of the anterior surface of the respective sternum half, and a third portion that is configured to cover at least part of the posterior surface of the respective sternum half;
- and
- a coupling surface configured to extend in the vertical direction z between an anterior and a posterior side of the sternum is arranged on each bone attachment plate, on a side opposite to the first portion of the bone attachment surface that is configured to cover at least a portion of said incision surface, wherein said coupling surface of the first bone attachment plate is configured to be coupled to the coupling surface of the second bone attachment plate.
