OBJECTIVE Comminuted fractures of the radial head represent a particular therapeutic problem. Due to characteristic complications the resection as well as the implantation of the Swanson-prothesis could not convince. METHODS We applied the radial head prothesis of Judet in 16 cases (14 type IV and 4 type III by Mason). RESULTS At the moment we survey the follow up of 15 patients after 12 to 45 months (average 18.2), the evaluation was performed using the score of Radin and Riseborough and the score of Morrey. With the score of Radin and Riseborough we found in 7 cases good, in 6 case fair and in 2 case poor results. With the score of Morrey we found 2 excellent, 11 good and 1 fair and poor results. The radiological examination did not show an increase of the carrying angle of the elbow, an osteoporosis, a proximal migration of the radius and a distal radio-ulnar dissociation. CONCLUSIONS Compared with resection or Swanson-prothesis the bipolar prothesis of Judet has definite advantages.
