Title: Finger joint prosthesis esp. for main hand to finger joint
Inventor: SCHMIDT KLAUS DR
IPC: A61F2/30
Filed: 1995-05-06
Abstract: The artificial joint consists of two rods (1,2) and a ball joint. The cylindrical outer surfaces of the rods have linear grooves. The rods are inserted in the bone cavities. One rod, which is inserted in the finger, has a flange (3) which is at right angles to its centreline. The other rod has a flange (4) which lies at an angle of approximately 45 degrees to its centreline. A ball joint (5,8) is mounted between the flanges (3,4).
