Calcaneum translation plate
A calcaneum translation plate having two end portions, i.e. a proximal anchoring portion and a distal fixing portion, oriented in opposing directions and arranged in spaced parallel planes, the proximal and distal portions connecting to an intermediate portion having a square general profile and having two perpendicular bearing surfaces, the proximal anchoring portion extending from one of the surfaces and perpendicular thereto, whereas the distal fixing portion extends in the extension of the other bearing surface.
1. Calcaneum translation plate wherein the calcaneum translation plate comprises two end portions, i.e. a proximal anchoring portion and a distal fixing portion oriented in opposing directions and arranged in spaced parallel planes, said proximal and distal portions being connected to an intermediate portion presenting a square general profile and featuring two perpendicular bearing surfaces, wherein the proximal anchoring portion extends from one of these bearing surfaces and perpendicularly thereto, whereas the distal fixing portion extends in g prolongation of the other bearing surface, and wherein the proximal anchoring portion is constituted by a blade presenting a narrowing profile in a direction of its free end.
2. Calcanean translation plate according to claim 1 , wherein said blade is provided with anti-backoff teeth.
3. Calcanean translation plate according to claim 2 , wherein said anti-backoff teeth are positioned on lateral edges of the proximal anchoring portion.
4. Calcanean translation plate according to claim 1 , wherein the intermediate portion presents a shoulder at the bearing surface from which the proximal anchoring portion extends.
5. Calcanean translation plate according to claim 1 , wherein the distal fixing portion features at least one hole for passage of at least one fastening screw.
6. Calcanean translation plate according to claim 1 , wherein the intermediate portion presents a concavity featuring one or several holes for passage of one or several fastening screws.
7. Calcanean translation plate according to claim 1 , wherein the distal and intermediate portions are both provided with holes for passage of screws, an axis of a hole of the intermediate portion being inclined relative to an axis of a hole of the distal fixing portion.
8. Calcanean translation plate according to claim 7 , wherein the distal and intermediate portions each present two holes for passage of screws.
9. Calcanean translation plate according to claim 5 , wherein said at least one hole has a conical shape.
10. Calcanean translation plate according to claim 1 , wherein the distal fixing portion presents an embossing on a face intended to come into contact with a bone.
11. Calcanean translation plate according to claim 1 , wherein the intermediate portion presents, on its lateral edges, reinforcing gussets.
12. Calcanean translation plate according to claim 6 , wherein said one or several holes have a conical shape.
