Abstract: A medical implant (1) designed to enable bony fusion between a first bone (20) and a second bone (21), said implant being in the form of an elongate part comprising, extending along the longitudinal axis of the part, a head (2) and a body (3) spaced apart from each other by a connection zone (4) connecting the head (2) to the body (3), said head (2) being suitable for being inserted into the first bone (20), said body (3) being suitable for being inserted into the second bone (21), said body (3) being a hollow body that is slotted longitudinally along at least a portion of its length in order to define at least three elastically deformable longitudinal tabs (5) by means of which said body (3) is suitable for being inserted into the second bone (21). Each longitudinal tab (5) of the body (3) is an arcuate tab (5) that presents an outer face (6), i.e.

Abstract: A polyaxial bone fastener assembly (1) comprising a plate (2) with at least one through orifice (3), and at least one fastener screw (4) for fastening the plate (2) to a bone, the body (6) of the screw (4) being suitable for passing through the orifice (3), and its head (5) being suitable for being retained in the orifice (3) of the plate (2) by bearing contact between complementary male and female spherical surfaces (7, 8), the female spherical surface (8) that is arranged in the orifice (3) of the plate (2) forming a seat within which the male spherical surface (7) is suitable for coming to bear when the screw (4) is inserted in the orifice (3).

Abstract: A subtalar implant for arthroereisis of the talocalcaneal joint. The implant is intended to be inserted into the talocalcaneal joint via its lateral orifice and has an oblong shape that extends longitudinally along an axis of insertion of the implant. The implant includes: a head with the shape of a cone of revolution centred on the axis of insertion; an anchoring thread; and a rod having the shape of a cylinder of revolution. The rod has, on its surface, the anchoring thread and being configured to be inserted up to the axis of rotation of the talocalcaneal joint. The head has, on its radially outer surface, a retaining element for retaining the implant in rotation about the axis of insertion, the retaining element exerting retention against a colonising tissue.

Abstract: A T-shaped plate for osteosynthesis, has at least three first attachment holes (124) and second attachment holes (113) including a curved linkage area (13). The epiphysis portion has a recess (34) with a curved profile from one end to the other of the T-bar when viewed from the top, and a curved profile when viewed from the side, and the diaphysis portion is straight and rigid. The plate is non-deformable at normal temperatures. The leg of the T has a rounded inner surface (56). The linkage area (13) has an S-shaped longitudinal cross-section, the ends (132, 133) of which that are adjoined with the bar and leg of the T, respectively, are substantially parallel to one another.

Abstract: A kit of the type including at least an implant (1), a gripper (2) for gripping the implant (1), and a storage element (7) for storing the gripper (7) and its associated implant (1), the storage element (7) including at least one reception location (71) for receiving the gripper (2) and its associated implant (1), and a tracer element (8) for tracing the implant (1). The tracer element (8) is sandwiched between the gripper (2) and the storage element (7), when the gripper (2) and its associated implant (1) are in their stored state in a reception location (71) of the storage element (7).

Abstract: A kit includes: an implant having a distal end for inserting the implant into the body; and a gripper in the form of a hollow elongate body that is open at at least one end, that is slotted longitudinally, and made, at least partly, of an elastically-deformable material, the slot opening out into the axial cavity of the body, inside which the implant is suitable for insertion, with its distal end projecting from the “distal” end of the body. The kit includes at least one reception sheath for receiving the distal end of the implant in order to separate the implant from its gripper by moving the sheath and the gripper relative to each other in the direction that breaks the alignment between them, the sheath has a bearing seat against which the implant bears both when the implant is inserted in the sheath, and when separated from its gripper.

The epiphysis portion has a recess (34) with a curved profile from one end to the other of the T-bar when viewed from the top, and a curved profile when viewed from the side, and the diaphysis portion is straight and rigid.

The linkage area (13) has an S-shaped longitudinal cross-section, the ends (132, 133) of which that are adjoined with the bar and leg of the T, respectively, are substantially parallel to one another.

Abstract: The osteosynthesis device includes a plate for pressing against a bone and at least one threaded rod for holding the plate on the bone, the rod presenting a first thread for anchoring the rod in a bone and a second thread for co-operating with a tapped thread formed in the plate, the device being characterized in that the thread root of the second thread defines a body of cylindrical shape and in that the thread crest of the second thread defines a truncated cone.
