A computer-implemented method and a system for computer guided surgery, which include a transposition of an action, planned in a virtual environment with respect to a virtual referential R, to a physical action performed with a surgical tool in a real operating theatre environment for orthopedic surgery of a patient.

Method and system for computer guided surgery

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.

A surgical system including a machining tool aimed at being manually displaced by an operator, a lockable unit including at least two linked and manually displaceable elements aimed at being manually arranged according to a least one calculated locked configuration, a sensor unit including at least one sensor aimed at following, in real time, a real time configuration of the lockable unit within an anatomical reference system, where the at least two elements of the lockable unit cooperate with lockable element, the lockable element being configured to be activated by a control unit when the real time configuration of the lockable unit corresponds to the at least one locked configuration recorded inside the control unit.

Lockable surgical system

A surgical system including a machining tool aimed at being manually displaced by an operator, a lockable unit including at least two linked and manually displaceable elements aimed at being manually arranged according to a least one calculated locked configuration, a sensor unit including at least one sensor aimed at following, in real time, a real time configuration of the lockable unit within an anatomical reference system, &#x2014;where the at least two elements of the lockable unit cooperate with lockable element, the lockable element being configured to be activated by a control unit when the real time configuration of the lockable unit corresponds to the at least one locked configuration recorded inside the control unit.

This tibial implant () comprises a tibial base () intended to be fastened to a resected proximal end of a tibia of a patient, the tibial base () comprising a medial bearing portion () and a lateral bearing portion (); and a tibial insert () shaped to be mounted on the tibial base (), the tibial insert () comprising a medial insert portion () including a concave medial bearing surface () intended to cooperate with a medial condyle of a femoral component or of a femur, and a lateral insert portion () including a concave lateral bearing surface () intended to cooperate with a lateral condyle of the femoral component or of the femur. The lateral insert portion () has, at its postero-lateral edge (), an insert notch () for the passage of the tendon of the popliteus, and/or the lateral bearing portion () has, at its postero-lateral edge (), a base notch () for the passage of the tendon of the popliteus.

Tibial implant for knee 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 line of cotyloid implants of different sizes including a cup intended to be fastened in a cotyloid cavity and including a substantially hemispherical polar portion and an equatorial portion extending the polar portion, the polar portion and the equatorial portion delimiting a substantially hemispherical inner cavity, an insert pivotally mounted in the inner cavity delimited by the polar and equatorial portions of the cup, the insert delimiting an inner cavity having an inner spherical surface portion and intended to pivotally and retentively mount a prosthetic femoral head, where the height of the equatorial portions of the cups of the various cotyloid implants belonging to the line varies in a decreasing manner as a function of the increase in the size of the cotyloid implants.

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

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.
