The invention concerns a set for fixing a soft tissue, such as a ligament or tendon on a bone, comprising two nails (10) and a member for positioning and setting (30) said nails in the superimposed soft tissue and bone. Said two nails comprise a first cylindrical upper portion and a second lower portion formed by a stepped coaxial superposition of inverted cones. The cylindrical portion is provided with a hole for passing through a suture (40) designed to constitute means for maintaining the soft tissue in position on the bone during healing The positioning and setting member (30) comprises a handle (31) wherein is nested a cylindrical rod (32) including an end (33). Said U-shaped end comprises two branches (35) provided with a blind cylindrical bore designed to receive the cylindrical part of the nails (10). When the nails are secured to the member (30), the suture (40) is maintained by the stop elements (34) of the handle (31).
A system for fixing connective tissue, notably a ligament or tendon, to a bone by means of at least two pins, each pin (10) comprising of a cylindrical superior section (11) and an inferior section (12) formed by a superimposition of inverted cones (14) having a directrix whose diameter is superior to the diameter of the cylindrical section (11), this fixing system consisting of a connecting means (40) of the two pins, a means for maintaining in position (50) the connective tissue to the bone after the pin have been put in place, each pin (10) having a form so as to prevent its vertical movement in the bone after it has been put in place, characterised in that it comprises a device for simultaneously positioning and inserting (30), in the superposed connective tissue and bone, the two pins joined by the connecting means, with a defined spacing between them and in that the connecting means is suture material (40).
A procedure for fixing connective tissue, notably of a ligament or a tendon, to a bone by means of at least two pins, by means of the fixing system described in the preceding claims, characterised in that it comprises the following steps:
