Percutaneous probe reduction of frontal fractures of the humeral capitellum.

Nine frontal fractures of the humeral capitellum treated by percutaneous probe reduction are reported. Most of the fractures were percutaneously reduced with a Steinmann pin inserted along the lateral border of the biceps tendon. To prevent redisplacement of the fragment, the elbow joint was first flexed more than 90 degrees with plaster immobilization for two weeks. The favorable results obtained with this method are due to reduced surgical trauma to local tissues and good reduction of the fracture. The percutaneous probe reduction should be considered for frontal fracture of the humeral capitellum before open reduction is performed.
