Abstract

An instrument system for the operative correction of vertebral displacements and for the stabilizing of repositioned vertebral bodies is described which is characterized by correction and support devices which are formed in two parts and which are displaceable in the axial direction guided relative to one another by means of an integrated setting member, as well as by interim spacers which are adapted in their spacer dimensions to the respective correction and support devices and by perforated hollow cylinder implants which are provided with outwardly lying fixing members and which are replaceable by the correction and support devices in repositioned vertebral bodies.
