摘要： 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.

摘要： A system for preparing an ankle bone to receive an ankle prosthesis is provided. The system includes a patient specific cutting guide that has an anterior surface, a posterior surface, and at least one cutting feature extending through the guide from the anterior surface. The posterior surface comprising a first protrusion or other member that extends from a first end fixed to the posterior surface to a second end disposed away from the first end of the first protrusion. The posterior surface has a second protrusion or other member that extends from a first end fixed to the posterior surface to a second end disposed away from the first end of the second protrusion. The first and second protrusions are spaced apart and have a length such that when the patient specific cutting guide is coupled with first and second bone references, which can include bushings implantable in bones, a clearance gap is provided between the posterior surface and the ankle bone.

摘要： 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.
