Abstract
An implant for intersomatic fusion of two adjacent vertebrae, particularly by an operation that was performed in posterior manner. The implant has a first implant part and a second implant part that is adjustable relative to the former, for the purpose of distraction. The first implant part and the second implant part are structured so that they supplement one another, in a complementary manner, in the non-distracted state, to form a pipe that is divided in the longitudinal direction. Guide surfaces that extend radially in the distraction direction, and rest against one another are formed on the first implant part and the second implant part. The relative position of the guide surfaces is fixed in place. An instrument for the placement and distraction of the implant is also provided.
