Abstract
The invention relates to a pedicle screw comprising a head (11) for coupling to an elastic intervertebral stabilizing or supporting system and comprising a shank, which is to be anchored inside a vertebra and which, when implanted, extends through the pedicle and into the vertebral body. The shank comprises, in its longitudinal extension measured from the head: an upper shank area (19) adjacent to the head and a stress-relief area (17), which is joined to the upper shank area, the stress-relive area having a flexural strength less than that of the upper shank area, and the stress-relief area is placed in the area of the shank provided for being placed inside the bone.
