Abstract

The invention relates to a medical device for positioning bone elements, in particular vertebrae, relative to each other, comprising at least one assembly built up of two or more anchoring elements, which can each be implanted in a bone element with a first end thereof, as well as an elongated connecting element, which can be connected to the other ends of the anchoring elements projecting from the bone element in question. The object of the invention is to provide an improved medical device as referred to in the introduction, placement of which requires a simpler procedure and thus less drastic surgery, which is less burdening for the patient, therefore. According to the invention, the medical device is characterised in that a tool is provided for use in the placement, part by part, of the medical device, which tool comprises at least two hollow, tubular guide members, which guide members can each be positioned into abutment with a bone element for guiding the anchoring elements through the guide member and inserting said anchoring elements in the bone element, as well as an adjusting mechanism, which can be connected to the other ends of the guide members for positioning the guide members and the bone elements relative to each other.
