Abstract
The present invention is related to a prosthesis, in particular a revision prosthesis, for repositioning and fixating acetabulum fractures. The prosthesis comprises a cup member (1), a hook member (2) and a hook retraction member (3). The cup member is formed and configured to be fixable into an acetabular cup. The hook member is formed and configured to be fixable onto an edge of the acetabular cup. The cup member and the hook member are formed and configured to be retractable into one another. The hook retraction member comprises at least one cable arranged and configured for retracting the hook member into the cup member.
Claims16
A prosthesis for repositioning and fixating acetabulum fractures, comprising:
- a cup member formed and configured to be fixable into a portion of a fractured acetabular socket;
- a hook member formed and configured to be fixable onto an edge of the other portion of the fractured acetabular socket, wherein the cup member and the hook member are formed and configured to be retractable into one another;
- and
- a hook retraction member comprising at least one cable arranged and configured for retracting the hook member into the cup member by which the portions of the fractured acetabular socket are retracted towards one another.
A retraction prosthesis, comprising:
- a first plate member formed and configured to be fixable at a first part of a bone fracture;
- a second plate member formed and configured to be fixable at a second part of the bone fracture;
- and
- a retraction member comprising at least one cable arranged and configured for retracting the second plate member towards the first plate member,
- wherein the first plate member and the retraction member are configured such that the retraction member can be fixated at the first plate member in a retracted position with bone cement where the second plate member is retracted at the first plate member, optionally wherein the bone cement comprises polymethyl methacrylate.
