Calcaneum translation plate
A calcaneum translation plate ( 1 ) characterized in that it comprises two end portions, i.e. a proximal anchoring portion ( 2 ) and a distal fixing portion ( 3 ), oriented in opposing directions and arranged in spaced parallel planes (P-P, P′-P′), said proximal and distal portions connecting to an intermediate portion ( 4 ) having a square general profile and comprising two perpendicular bearing surfaces, the proximal anchoring portion extending from one ( 5 ) of said surfaces and perpendicular thereto, whereas the distal fixing portion extends in the extension of the other bearing surface ( 6 ).
1. Calcaneum translation plate, wherein the calcaneum translation plate comprises two end portions, i.e. a proximal anchoring portion and a distal fixing portion which are oriented in opposing directions and which are arranged respectively in a proximal plane and in a distal plane, the proximal and distal planes being spaced and parallel, wherein said proximal and distal portions are 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 the prolongation of the other bearing surface, and wherein the intermediate portion presents a shoulder at the bearing surface from which the proximal anchoring portion extends, the shoulder being located on a side of the proximal plane, opposed to the distal plane.
2. Calcaneum translation plate according to claim 1 , wherein the distal fixing portion features at least one hole for passage of at least one fastening screw.
3. Calcaneum 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.
4. Calcaneum 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.
5. Calcaneum translation plate according to claim 4 , wherein the distal and intermediate portions each present two holes for passage of screws.
6. Calcaneum translation plate according to claim 2 , wherein said at least one hole has a conical shape.
7. Calcaneum translation plate according to claim 1 , wherein the distal fixing portion presents an embossing on a face intended to come into contact with the bone.
8. Calcaneum translation plate according to claim 1 , wherein the intermediate portion presents, on its lateral edges, reinforcing gussets.
9. Calcaneum translation plate according to claim 3 , wherein said one or several holes have a conical shape.
10. Calcaneum translation plate according to claim 1 , wherein the proximal anchoring portion does not have any holes.
11. Calcaneum translation plate according to claim 1 , wherein the proximal anchoring portion is designed to be inserted into calcaneum spongy bone.
