Abstract
The invention relates to a distance measuring instrument for pedicle screws which detects the spacing between two pedicle screws (') with the ends () of two crossing limbs () and displays it on a cross-bar () fixedly connected to one of the limbs at a scale (). Since the second limb () is divided into a pointer () and into a flexural spring extending parallel to it at which a pronounced thumb grip () is fastened, and since the thumb grip is connected to a scale () via which a pre-determined pre-tension can be read off relative to the pointer (), a spacing measurement can take place under a controlled pre-tension.
