Abstract:
A device for the femoral fixation of the semitendinosus and gracilis tendons for the reconstruction of the anterior cruciate ligament, comprising: an elongated body (1); means (2, 3) for anchoring said tendons to said body (1), formed in correspondence to a distal end of the body; and a set bar (9) pivotally supported by said body (1) about a transverse axis in correspondence to a proximal end of the body (1), said set bar (9) comprising a couple of coaxial stop arms (9b) and being pivotable between two insertion positions, angularly spaced by 180Â°, in each insertion position a respective stop arm (9b) extending beyond the proximal end of said body (1), coaxially thereto, whereby the device is inserted into consecutive tunnels (12a, 13a) preliminarily formed in the tibia (12) and femur (13) of a patient, while keeping said set bar (9) in a insertion position, until the proximal end of said body (1) partly projects out of the femoral tunnel (13a), and in such condition said set bar (9) is rotated to a fixation position, intermediate between said insertion positions, in order to cause the abutment of said stop arms (9b) against the cortical surface (13b) of said femur (13), the sliding of said body (1) within said tunnels (12a, 13a) and the rotation of said set bar (9) being operated by the surgeon via threads (14a, 14b) attached to the respective stop arms (9b).
