Abstract: In one embodiment, the present invention is an anchoring rod that is elongated and tapered, the rod extends from a distal end toward a proximal end, the shape including a palmate side, a dorsal side and lateral sides, is the shape being flared on its palmate side without flaring on its dorsal side and flares on its lateral sides so as to form a flared proximal portion, said flared proximal portion having a substantially trapezoidal cross-section, with a dorsal face larger than the palmate face.

Abstract: An assembly for reducing a fracture between an epiphysis and a diaphysis of a bone has a bone plate having a fan-shaped outer end formed with a plurality of outer holes and a bar-shaped inner end extending along a longitudinal axis from the outer end and formed with a plurality of inner holes. The plate further is formed on the bar-shaped inner end with a longitudinally extending through going guide slot and between the guide slot and the outer holes with an aperture. A slide has a longitudinally extending leg with an inner end formed with a guide formation engaged into and longitudinally slidable along the guide slot and a crosspiece overlying the aperture and engaging the bone plate to both transverse sides of the aperture. The crosspiece is formed with a transversely elongated slide slot, and a slide screw engaged through the slide.

Abstract: An orthopaedic implant used in arthroplasty of the fingers comprises a first element for a proximal phalanx and a second element for an adjacent distal phalanx, each element having a respective stem for implantation in the bone and an interphalangeal articulation head, the head of the first element having a biconvex surface of articulation, with a central valley, and the head of the second element having a biconcave surface of articulation designed to cooperate with said convex surface and comprising a central crest. At rest, the surfaces are congruent in the frontal plane of the articulation in the area of the condyles and non-congruent in the sagittal plane.

Abstract: An intramedullary anchoring stem for an orthopaedic implant head. The stem is in one piece, is made of biocompatible material and is movable in relation to the head, with which it has connecting means, and it has a truncated or substantially truncated peg shape at least partially recessed longitudinally, and parallel or substantially parallel to the dorso-palmar plane.

Abstract: 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.

Abstract: An orthopaedic implant (2) used in arthroplasty of the fingers comprises a first element (3) for a proximal phalanx (4) and a second element (5) for an adjacent distal phalanx (6), each element having a respective stem (7, 8) for implantation in the bone and an interphalangeal articulation head (9, 10), the head (9) of the first element having a biconvex surface (11) of articulation, with a central valley (12), and the head (10) of the second element having a biconcave surface (13) of articulation designed to cooperate with said convex surface and comprising a central crest (14). At rest, the surfaces (11, 13) are congruent in the frontal plane of the articulation in the area of the condyles and non-congruent in the sagittal plane.
