LOCKING PLATE SYSTEM FOR BONE FRACTURE TREATMENT OF RADIUS DISTAL END

摘要

PROBLEM TO BE SOLVED: To provide a locking plate system for bone fracture treatment of the distal end of a radius in which the cooperativity between a metallic screw anchor and a resin-made plate is improved and the matching properties to the radius is improved.SOLUTION: A radius locking plate 4 is a flat laminate of an intermediate material for molding of a thermoplastic resin for a matrix by using a carbon fiber as a reinforcing material. A main self-tapping screw 11 is formed in a shaft 10 of a screw anchor 5, and on the other hand, a second self-tapping screw 13 is engraved in a head outer circumference of the screw anchor 5. The diameter of a through-hole 6 provided in the radius locking plate 4 for screwing a radius body 3 and a bone fracture piece 2 is oversized to the main screw 11, and undersized to the second screw 13.SELECTED DRAWING: Figure 1
