Abstract

An adjustable spinal joint for use with fixation instruments intended for fixating lumbal vertebrae to the sacrum, wherein the spinal joint includes a cranial part which is provided with a pin provided with longitudinally extending splines or serrations, and a caudal part which is provided with a bore having corresponding internal, longitudinally extending splines or serrations. These splines or serrations mesh with one another after desired variable adjustment when a screw provided in the caudal part has been tightened. The longitudinal splines or serrations are oriented so that those forces that act on the cranial part are transferred to the caudal part without the splines or serrations meshing with one another prior to tightening the screw.
