Abstract: This system comprises: at least one vibrational sensor which is operable to produce data each time an impact application device applies an impact from a user to the prosthetic component during assembly between the prosthetic component and with the support member, the produced data representing acoustic vibrations generated in the air and/or material vibrations generated in the impact application device, an analysis unit which is configured both to calculate a frequency characterization of the vibrations for each impact applied by the impact application device to the prosthetic component, from the corresponding data produced by the at least one vibrational sensor, and to compare the frequency characterizations that are respectively calculated for successive impacts so as to provide at each of the successive impacts either a first indication when the assembly between the prosthetic component and the support member is not fully seated or a second indication when the assembly between the prosthetic component and

Abstract: The invention relates to a base that includes a unit for osseous attachment onto a tibia, and a plate having posterior, anterior, medial and lateral edges; a posterior pin and an anterior pin having a posterior flat section and an anterior flat section; two posterior lugs protruding above the plate and arranged on the posterior edge of each side of the posterior pin; and two anterior lugs arranged on each side of the anterior pin. The posterior flat section and the anterior flat section are arranged so as to simultaneously engage with the insert. Each posterior tab includes a support extension for inserting, in an anteroposterior direction, a complementary support tab of the insert. Each anterior lug includes a unit for snap-coupling the insert onto the base.

Abstract: A jig for resurfacing the head of a femur comprises a centering guide defining a centering axis. It further comprises: a support suitable for fitting on a head of the femur and defining an envelope surface forming a portion of a sphere, the centering guide being fastened to the support with the centering axis aligned on a diameter of the sphere; and at least one abutment arm for coming into abutment against a predefined portion of a neck of the femur, the abutment arm being connected to the support and having a distal end that bears against the corresponding predefined portion when the support is fitted on the head of the femur with the centering axis aligned on the central axis of the neck of the femur or with a small amount of valgus.
