Plate for fixing the bones of a joint, in particular a metatarso-phalangeal joint

Abstract

A plate for fixing the bones of a joint, in particular of a metatarso-phalangeal joint, for the purpose of performing arthodesis. The plate comprises two sections, respectively a proximal section and a distal section, each section having a respective longitudinal axis of symmetry S 1 , S 2 such that the projection onto a horizontal plane of the axis of symmetry S 2 of the distal section presents an angle of inclination relative to the projection of the axis of symmetry S 1 of the proximal portion, the projections inserting at a point A. The projection onto a vertical plane of the axis of symmetry S 2 presents an angle of inclination relative to the projection of the axis of symmetry S 1 , their intersection taking place at a point A 2 which is distinct from the point A 1 .

1 . A surgical device comprising: 
 a plate having a plurality of holes for receiving respective screws to fix the plate to at least one bone, wherein the plate further comprises:    a first portion comprising an elongate body extending along a first axis through a first plane and comprising at least one of the plurality of holes; and    a second portion comprising an elongate body comprising at least one of the plurality of holes, the second portion comprising a first length and second length, the first length extending along a second axis and through the first plane, the second axis of the first length having a pre-established non-zero angle α with respect to the first axis of the first portion, the second length of the second portion extending along a third axis and through a second plane different from the first plane, the second plane of the second length having a pre-established non-zero angle β with respect to the first plane,    wherein the first axis and the second axis intersect at a point A 1 , and the projection of the third axis onto the first plane intersects with point A 1 .    
     
     
         2 . A plate for fixing the bones of a metatarso-phalangeal joint in order to perform arthrodesis, said plate having a plurality of holes for receiving respective screws to fix the plate to the bone fragments to be fused together, wherein the plate further comprises a first portion comprising an elongate body which comprises at least one of the plurality of holes and a second portion comprising an elongate body which comprises at least one of the plurality of holes, the projection onto an horizontal plane of the second portion having a pre-established non-zero angle α with respect to the projection onto an horizontal plane of the first portion, and the projection onto a vertical plane of the second portion having a pre-established non-zero angle β with respect to the projection onto a vertical plane of the first portion.
