Prosthetic device with multi-axis dual bearing assembly and methods for resection
Abstract:
An orthopedic prosthesis, system and method has a dual bearing component that, along with first and second bone anchoring components, provides multi-axial movement separately with respect to both the first and second bone anchoring components. An ankle prosthesis, system and method may thus be fashioned utilizing these principles that includes a dual bearing component, a tibial component adapted for attachment to the tibia bone, and a talar component adapted for attachment to the talus or calceneus bone of the foot. The dual bearing component includes a superior bearing providing gliding articulation/translation between it and the tibial component, and an inferior bearing providing gliding articulation/translation between it and the talar component. A bearing component plate provides a base or foundation for the superior and inferior bearings. The superior bearing is bonded to the bearing component plate while the inferior bearing moves with respect to the bearing component plate.
