In order to position an ankle prosthesis including a tibial implant and a talus implant provided with a talo-calcaneal anchoring keel, the invention proposes a surgical instrumentation assembly including: a tibial phantom () of the tibial implant, adapted so as to be attached to the tibia (T) of a patient, and an aiming guide () adapted for setting into place an instrumentation element () through the talus (A) and the calcaneus (C) of the patient, along an axis (Z-Z) for implanting the talo-calcaneal anchoring keel, the tibial phantom and the aiming guide mechanically cooperating with each other to restrict movement of the tibial phantom and the aiming guide relative to each other along vertical and medio-lateral directions, wherein the aiming guide is configured to guide placement of the instrumentation element.

Surgical instrumentation assembly for positioning an ankle prosthesis

A surgical instrument including at least one tibial phantom generally corresponding to at least certain features of the tibial implant. The tibial phantom includes a top surface adapted to move freely against the prepared bottom end of the tibia. At least one talus phantom generally corresponding to at least certain features of the talus implant is engaged with the prepared top surface of the talus. At least one phantom skid is located between the tibial phantom and the talus phantom. The phantom skid is engaged with the tibial phantom such that dynamic engagement between the phantom skid and the talus phantom through at least extension and flexion of the ankle joint positions the tibial phantom on the prepared bottom end of the tibia. The phantom skid can either be a part of the tibial phantom or a separate component.

Surgical instrumentation kit for inserting an ankle prosthesis

A method for implanting a malleolar implant in an ankle joint. A spacer block is positioned between a lower portion of a tibia and an upper portion of an astragalus in the ankle joint. A guide attached to the spacer block is positioned opposite an outer surface of a fibular malleolus. A bore aligned with the guide is formed through the fibular malleolus. The spacer block is removed from between the tibia and the astragalus. A shank of the malleolar implant is engaged with the bore from an inner surface of the fibular malleolus. The shank is advanced into the bore so an inner surface of a head of the malleolar implant engages the inner surface of the fibular malleolus.

Method for placing a malleolar implant

The knee prosthesis with rotary plate comprises a metal base () and a tibia plate () which are equipped with guide means () defining a center of rotation (C,C') which may be offset from that of the tibia bone axis (YY&#x2032;), so as to allow the tibia plate () to slide in rotation over the said base, the said guide means being positioned a certain distance away from the center of rotation (C, C&#x2032;).

Knee prosthesis with a rotational plate

A tool for placing a malleolar implant for partial or total ankle prosthesis, which includes a spacer block, adapted to be inserted between a tibia and an astragalus of an ankle, a lug secured to the block and extending to a vicinity of an outer surface of a fibular malleolus when the spacer block is in position, and the lug supporting a guide for boring the malleolus from its outer surface.

Tool for placing a malleolar implant for partial or total ankle prosthesis

A method of positioning a malleolar implant for partial or total ankle prosthesis wherein the implant includes a head intended to bear against the astragalus or astragalian prosthetic component and a shank provided to be introduced in a bore in the fibula including providing an orifice in the shank and inserting the implant in the bore by use of force applied along a flexible traction member extending through the orifice.

Method of positioning a malleolar implant for partial or total ankle prosthesis

A malleolar implant for partial or total ankle prosthesis which includes a head having a surface to bear against an astragalus or astragalian prosthetic component and from which head extends a shank adapted to be inserted through a bore in a fibula wherein the shank is provided with means for hooking a traction member which is adapted to be inserted through the bore in the fibula in order to apply a force to pull the implant into the bore such that the implant is seated within the bore of the fibula.

Malleolar implant for partial or total ankle prosthesis

Knee prosthesis comprising a metal base secured to an anchoring rod for fixing it into a tibia of a patient. A plastic tibia plate is freely slidable over the base. The metal base and the tibia plate are equipped with a guide mechanism defining a center of rotation offset from that of a tibia bone axis, so as to allow the plate to slide in rotation over the base. The guide mechanism is positioned a given distance from the center of rotation. The metal base comprises an upstand in the shape of an arc of a circle having a central part secured to lateral edges which are shorter than the central part. The tibia plate comprises, on a lower face thereof, a housing in the shape of an arc of a circle.

An ankle prosthesis, comprising a tibial element and an talar element (,), each provided with anchoring means on the lower extremity of a tibia and on the astragalus, respectively, and each delimiting an articular surface, both articular surfaces being shaped in order to interact as a whole and to provide a relative movement between the two tibial and talar elements around at last one axis. It is especially characterized by the fact that, taking as reference direction the direction of the axis of the tibia on which it is intended to anchor the tibial element, seen in projection on a plane approximately perpendicular to this reference direction, the articular surfaces are curved with a concavity towards the inside of the foot onto which is to be anchored the talar element.

Ankle prosthesis

A total elbow prosthesis includes a radial element having an anchoring stem provided with a neck which is inclined by an angle of between 0.degree. and 30.degree. relative to the axis of the anchoring stem. The neck is integral with a ball on which a cylindrical head articulates. The cylindrical articulating head includes an upper face of concave profile which cooperates with the epicondylar surface of the humeral element and a cylindrical circumference cooperating with an outer articular surface provided on the outer flank of a flange of the ulnar element.

Total elbow prosthesis

A device for stabilizing fractures of the upper end of the femur, comprising a plate which includes in its upper part two parallel, cylindrical barrels offset by a first angle with respect to a vertical plane passing through the middle of the plate and a second angle with respect to a horizontal axis passing through the middle of the plate.
