VERTEBRAL OSTEOSYNTHESIS EQUIPMENT ENABLING ILIAC ANCHORING OF A VERTEBRAL BAR

摘要

This equipment comprises an iliac rod (2), a connection assembly (3, 4) for connecting that iliac rod to a vertebral bar, an iliac anchoring member and an iliac part connecting the iliac rod to that iliac anchoring member; said connecting assembly (3, 4) is independent of the iliac rod (2) and comprises two portions, namely: —a first portion (3), for connecting to said vertebral bar (50), that forms a closed conduit (10) for engagement of that portion (3) on that bar (50); and —a second portion (4), for connecting to said iliac rod (2), that forms a conduit (12) for the engagement of that second portion (4) on the iliac rod (2). According to the invention, —said first portion is formed by a first connecting part (3) and said second portion is formed by a second connecting part (4), said first and second connecting parts (3, 4) being independent of one another; said first connecting part (3) comprises a portion (3a) that forms said closed conduit (10) and a threaded rod (3b) protruding from said portion (3a); said second connecting part (4) forms a passage (11) through it for the engagement of said threaded rod (3b) of the first connecting part (3), with a pivoting capacity of said second connecting part (4) relative to said first connecting part (3).

1. Vertebral osteosynthesis equipment enabling iliac anchoring of a vertebral bar, comprising an iliac rod, a connecting assembly for connecting that iliac rod to a vertebral bar, an iliac anchoring member and an iliac part for connecting the iliac rod to that iliac anchoring member;
said connecting assembly is independent of the iliac rod and comprises two portions, namely:
a first portion, for connecting to said vertebral bar, that forms a closed conduit for engagement of that portion on that bar, i.e., a conduit completely surrounding the bar when that first connecting portion is engaged on the bar; said conduit is dimensioned to allow an adjusted engagement of said first connecting portion on the bar; but with a pivoting capacity of that portion relative to that bar; anda second portion, for connecting to said iliac rod, that forms a conduit for the engagement of that second portion on the iliac rod.characterized in that:
said first portion is formed by a first connecting part and said second portion is formed by a second connecting part, said first and second connecting parts being independent of one another;
said first connecting part comprises a portion that forms said closed conduit and a threaded rod protruding from said portion;said second connecting part forms a passage through it for the engagement of said threaded rod of the first connecting part, with a pivoting capacity of said second connecting part relative to said first connecting part; and the equipment comprises a nut able to be screwed on said threaded rod so as to assemble said second connecting part to said first connecting part and, when it is tightened, to immobilize those two connecting parts relative to one another.
