摘要

A device for the femoral fixation of the ST and G tendons for the reconstruction of the ACL of the knee, comprises an elongated body (1), means (2) for anchoring the tendons to the body (1), formed in correspondence to a distal end thereof; and a set bar (9) pivotally supported by the elongated body about a transverse axis in correspondence to a proximal end thereof. The set bar (9) comprises a couple of coaxial stop arms (9b) and is pivotable between two insertion positions, angularly spaced by 180°. While keeping set bar (9) in a insertion position, the device is inserted into consecutive tunnels (12a, 13a) preliminarily formed in the tibia and femur, until the proximal end of the body (1) partly projects out of the femoral tunnel (13a). In such condition said set bar (9) is rotated to a fixation position in order to cause the abutment of the stop arms (9b) against the surface of the femur.
