A pedicle anchorage device (101) to be implanted in a human or animal vertebra (121) from a generally dorsal direction through one of the pedicles of the vertebra so that a distal part of the anchor device protrudes to the vertebral body of the vertebra, the pedicle anchoring device comprising a device body with a proximal head part (102) to secure an orthopedic device to stabilize the spine, and with a distal stem part (103) capable of being anchored in the vertebra , the device body further comprising a longitudinal bore (13) extending distally from a proximal end, and at least one hole (14, 19) from the longitudinal bore outward, the pedicle anchoring device further comprising a liquefiable element that is insertable or inserted into the longitudinal bore and at least partially liquefiable due to the impact of energy that falls from the proximal so that the liquefied material flows through at least one hole and out of the longitudinal bore to hard tissue structures and / or hard tissue replacement material characterized in that the stem portion (103) is not threaded and has a non-circular cross-section, and because the stem part (103) is helically twisted, with a twist of between 10 ° and 270 ° over the entire length of the pedicle anchoring device.Un dispositivo de anclaje pediculado (101) para ser implantado en una vértebra (121) humana o animal desde una dirección generalmente dorsal a través de uno de los pedículos de la vértebra de modo que una parte distal del dispositivo de anclaje sobresalga al cuerpo vertebral de la vértebra, comprendiendo el dispositivo de anclaje pediculado un cuerpo de dispositivo con una parte de cabeza proximal (102) para asegurar un dispositivo ortopédico para estabilizar la columna vertebral, y con una parte de vástago distal (103) capaz de ser anclada en la vértebra, comprendiendo el cuerpo del dispositivo además un ánima longitudinal (13) que se extiende distalmente desde un extremo proximal, y al menos un agujero (14, 19) desde
