<p>The invention relates to an intervertebral implant for the lumbosacral articulation. The inventive implant comprises a wedge (20) which is disposed between a fifth lumbar vertebra (L5) and the sacral vertebra (S1) which is articulated to L5. The upper face of the body of the wedge (21) comprises a groove (30) which is oriented along the mid-plane (M) of said wedge (20) and which can receive the spinous process (10) of the aforementioned lumbar vertebra (L5). According to the invention, a longitudinal housing, which is positioned orthogonally to the aforementioned groove (30), is provided on the lower face and is designed to receive the upper part (14) of the sacral vertebra (S1). The longitudinal housing is defined by an extension (32) and a tab (34) having a greater width than that of the body of the wedge. Moreover, the section of the housing, along the mid-plane (M) of the wedge, takes the general form of a U which is inclined in relation to the base of the groove (30).</p> |
