This surgical ankle repair method comprises the steps of providing an instrumentation assembly for positioning an ankle prosthesis, the instrumentation assembly including a talar alignment instrument and a cutting block, the talar alignment instrument comprising a front portion and two fins extending from the ends of the front portion, said fins being adapted to be positioned in gutters extending below a tibia of a patient and around a trochlea of a talus of the patient, each fin including a reference marker, the cutting block comprising a tibial alignment structure and a recess which engages a protrusion provided on the talar alignment instrument, positioning the talar alignment instrument such that the fins are disposed in the gutters extending below the tibia and around the trochlea of the talus; aligning the talar alignment instrument so that the fins are parallel to the rotational plane of the talus, perpendicular to the rotational axis of the talus, and so that the reference markers are aligned with a longitudinal axis of the tibia; confirming alignment of the reference markers via imaging technology; mechanically attaching the talar alignment instrument to the talus; fastening the cutting block to the talar alignment instrument such that the recess engages the protrusion locked in a parallel orientation to the rotational plane of the talus; rotating the talus such that the tibial alignment structure is in a parallel alignment to the longitudinal axis of the tibia, thereby correcting any varus or valgus deformity of the talus; attaching the tibial alignment structure to the tibia; and performing a first resection of the talus and at least one resection of the tibia using the cutting block.

Surgical method and instrumentation assembly for positioning an ankle prosthesis

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

This surgical ankle repair method comprises providing an instrumentation assembly for positioning an ankle prosthesis including a talar alignment instrument and a cutting block. The talar alignment instrument is positioned such that fins of the talar alignment instrument are disposed in gutters that extend below the tibia and around the trochlea of the talus. The talar alignment instrument is aligned so that the fins are parallel to the rotational plane of the talus. Alignment of the reference markers is confirmed. The talar alignment instrument is attached to the talus. The cutting block is fastened to the talar alignment instrument. The talus is rotated such that the tibial alignment structure is in a parallel alignment to the longitudinal axis of the tibia. The tibial alignment structure is attached to the tibia. A resection of the talus and at least one resection of the tibia is performed using the cutting block.

Prosthetic systems, devices, and methods for attaching prosthetic joint components to a vault-shaped portion of the anatomy. A device for attaching a glenoid joint component for a shoulder prosthesis to a glenoid cavity includes a body adapted to extend into the cortical bony vault of the glenoid cavity for supporting the glenoid joint component and a plurality of contact arms secured to the body and projecting outwardly from a central longitudinal axis of the body to define contact surfaces for engaging an internal face of a peripheral wall of a glenoid vault.

Joint prosthesis attachment system, device and method

This insertion and locking device () for an implant in a long bone comprises an elongate body () designed to be received in a medullary canal of the long bone, the body defining, in a first position called the insertion position, a first transverse size and, in a second position called the locking position, a second transverse size greater than the first transverse size. This device furthermore comprises drive mechanism () suited to enable the body () to move from the first position to the second position. In addition, the elongate body () comprises a central member () defining a main axis and at least one locking member () defining at least one axis of movement distinct from the main axis, the or each locking member () being suited to anchoring itself in the long bone under the effect of the drive mechanism.
