Système PHP Contours

The Contours Proximal Humeral Plate™ (PHP) is an anatomically shaped plate, one for the right and one for the left humerus. It has to be used in combination with at least two diaphyseal screws, a main locking screw and at least two fine threaded screws. The main stabilization of the humeral head is achieved with a cannulated main locking screw (slightly conical Ø 5.6 – 6 mm with 130° angle) to be inserted in the calcar area. This larger bore screw works as a cantilever, blocking the humeral head in the frontal plane. It transfers the main load to the diaphysis of the humerus. To complete the stabilization and fix fracture fragments, minimum two crossing Ø 2.2 mm polyaxial fine threaded screws are inserted and locked in the appropriate threaded holes. These thinner-bore screws work through traction and stabilize the humeral head in the sagittal and transversal planes. Distal locking is made in the three distal holes by inserting either the Ø 4.5 mm diaphyseal screws or the Ø 6.5 mm revision screws (when the bone quality is poor). Four suture holes with large grooves have been designed to allow a needle insertion thus facilitating sutures and cerclage procedures.
