Abstract

The invention relates to a pedicle screw for implants for the correction and stabilisation of the spinal column, comprising a head piece (4), on one axial end of a threaded shaft (2) to which a clamp piece (3) may be connected, comprising a clamp housing (5) for a bar (6) which may be fixed to the head piece (4). A threaded drilling (8) is embodied in the clamp piece (3) for housing a thread provided on the head piece (4).
