description The device for percutaneous transpedicular fusion (Sa) according to the present invention comprises: at least two straight pedicular cannulas (2a, 3a; 2b, 3b) arranged respectively either on the upper vertebra (Va), or on the lower vertebra (Vb) or on both vertebrae (Va, Vb) of the spinal segment; at least one guide pin (4) with curved profile which is implanted in the endplate (Pi, Ps) of the corresponding vertebra (Va, Vb) through the corresponding pedicular cannula; a flexible cannulated drill bit (5) guided around the corresponding guide pin (4) and driven in a to-and-fro movement by a cannulated driving system (6), in such a way as to progressively, and in a controlled manner, nibble out windows (F) in said lower endplate (Pi) and upper endplate (Ps) of each vertebra (Va, Vb) and to reduce to shreds the nucleic tissues of an intervertebral disc (D) in order to produce the intersomatic space (Es); an injection device (7) connected to one of the straight pedicular cannulas (2a, 3a; 2b, 3b) in order to inject the graft (8) into the intersomatic space (Es) thus produced; and plugs (9) screwing into the holes left free after the withdrawal of said straight pedicular cannulas.
