The hookplate here described has been used for the surgical fixation of small important bone fragments in 450 cases during the past 12 years. Most of these fragments have been parts of joint structures, the main force of displacement being distraction. This was successfully neutralized with the hookplate, which allows unicortical or bicortical screwfixation at right angles to the distraction force inside the solid cortical bone. There is no force to endanger the stability of this type of fixation. This method has been used in comminuted fractures of the olecranon or of the medial malleolus and fracture-dislocations of the ankle.
