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.

Embodiments of the present invention relate to surgical instrumentation specific to a patient for preparing a bone including a patient-specific block delimiting a supporting surface shaped to fit the bone, and a main portion partly delimiting the fixed supporting surface and at least two primary orifices for receiving a primary pin, crossing the block between the supporting surface and an opposite surface. The instrumentation also includes a secondary portion which belongs to the block, partly delimits the supporting surface and includes at least two secondary orifices for receiving a bone preparation tool crossing the block between the supporting surface and opposite surface, and a mechanism for mechanically disengaging the secondary portion with respect to the main portion, suitable for, when the main portion is attached onto the bone with primary pins passed into the primary orifices, making the secondary portion removable with respect to the main portion.
