摘要： A process for the production of a superelastic material out of a nickel and titanium alloy, characterized by the fact that it consists in obtaining an ingot starting from a mixing of nickel and titanium consisting in 55.6%.+-.0.4% in weight of nickel and to proceed with a thermal treatment of martensite plaquettes generation by subjecting said ingot during 5 to 45 minutes to a temperature comprised between 480 and 520.degree. C. The process allows the obtaining of a truly superelastic material at room temperature.

摘要： A bone plate for a fracture between an epiphysis and a diaphysis has an outer part unitarily formed with a fan-shaped outer end having a plurality of outer holes and an inner end extending from the outer end. A bar-shaped inner part has an outer end juxtaposed with the inner end of the outer part and formed inward of its outer end with a plurality of inner holes. A pivot is provided between the inner end of the outer part and the outer end of the inner part. Formations juxtaposed with the pivot on the inner end of the outer part and on the outer end of the inner part are lockable together in each of a plurality of angularly offset fixed positions of the inner and outer parts. When the formations are pressed together the inner and outer parts are locked angularly relative to each other.

摘要： The invention relates to a plate (1) fixed between two bone parts by means of screws engaged in holes (1b) formed in the thickness of said plate. The plate (1) comprises a rib which is inclined according to an angle of between 30° and 60° in relation to the plane defined by the plate and has a hole (1a1) for engaging a screw (2). Said rib is located in the central part of the width, over a determined part of the length of the plate so that the screw (2) brings the two bone parts into the compressive position.
