Calcaneum translation plate

Abstract

A calcaneum translation plate ( 1 ) characterised 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 ).
