Abstract: The medical implant (1) according to the present invention comprises a first, generally elongate portion (20) extending along the longitudinal axis A, intended to be inserted into the first bone (P1) and comprising first attachment means (24), and a second, also elongate, portion (30) following another longitudinal axis B, intended to be inserted into the second bone (P2) and comprising second attachment means (34), wherein said first and second portions (20, 30) are connected together via a connecting bridge (40) which is centered about the orthonormal axes X, Y, Z of said implant (1), providing for at least one axial offset of the second portion (30) with respect to the first portion (20) such that the longitudinal axis B of the second portion (30) is positioned in at least one direction forming an angle (?) relative to the longitudinal axis A of the first portion (20) and is offset by at least a certain distance along at least one of the axes XX?, YY? and ZZ? of the connecting bridge (40) in order to avoid

Abstract: The invention relates to an implant (1) for osseous fusion between two bones, including a first portion (20) having a longitudinal axis A, for being inserted in the first bone and including a first means (24) for attaching said implant in said first bone, and a second portion (30) having a longitudinal axis B, for being inserted in the second bone and including a second means (34) for attaching said implant in said second bone, said first and second portions (20, 30) being connected by a central core (40), said central core being a solid body, the cross-section of which, in a plane perpendicular to said longitudinal axis A, has the shape of a star having at least three points (41, 42, 43), said first portion having three tabs (21, 22, 23), each tab extending along said longitudinal axis A from the free end (41a, 42a, 43a) of one of the points of said central core.

Abstract: A surgical device for treating the pathology of flat feet, the device comprising an outer casing; and an expansion member suitable for moving inside said outer casing in a compression direction, for causing said outer casing to expand radially; the surgical device being provided with non-return check means shaped to allow the expansion member to move in the compression direction towards an operating position inside the outer casing and to oppose movement of the expansion member in the reverse direction once said operating position is reached, so as to prevent the expansion member from being expelled.

Abstract: Articular interposition implant to be placed between the articular surfaces of at least two bones separated by an articular interface to achieve arthroplasty of a joint, said implant (1) comprising immobilization means shaped so that when the immobilization means are arranged in the articular interface, the immobilization means are supportive of at least one of the articular surfaces, wherein said implant (1) extends along a longitudinal axis (X-X?) and wherein said immobilization means are shaped to prevent rotation of said implant (1) on itself with respect to said longitudinal axis (X-X?).

Abstract: The invention relates to a threaded pin for holding together pieces of a fractured bone. The pin comprises a body having a distal end and a proximal end. The distal end has a first thread presenting crests and the proximal end has a second thread presenting crests. The first thread and the second thread being spaced apart by a smooth portion. The first and second threads are such that the pitch X of the first thread and the pitch Y of the second thread both decrease from the distal end (X1, X2, Y1, Y2) towards the proximal end (Xn, Xn−1; Yn, Yn−1). The diameter d of the crests of the first thread and the diameter D of the crests of the second thread both increase from the distal end (d1, d2; D1, D2) towards the proximal end (dn, dn−1; Dn, Dn−1), and the values are such that: X1>X2>Xn−1>Xn>Y1>Y2>Yn−1>Yn and Dn>Dn−1>D2>D1>dn>dn−1>d2>d1. The invention is applicable to repairing bones.

Abstract: A surgical device implantable in the subtalar tunnel for treating the flat foot condition, composed of: a central cylindrical body having an outer cylindrical surface provided with a first screw thread; an expansion cone having a longitudinally extending internal bore provided with a second screw thread mateable with the first screw thread, the cone further having an external surface of conical form; and an external cylinder having an internal conical surface engageable with the cone and constructed to be radially expandable in response to movement of the cone in a longitudinal direction relative to the cylinder, the cone being longitudinally moveable by rotation relative to the cylindrical body while the first and second threads are in threaded engagement with one another.
