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.

A surgical retractor and method for retracting tissue in a patient is anatomically designed for particular muscles and includes a light source the light beam of which is positionable relative to the surgical retractor. The surgical retractor has a pair of retraction blades carried on separate retraction portions held open by ratchet assemblies. Blades are manually retracted and held open by automatically engaging ratchet fingers and are designed to match muscle curvature, minimizing various risks and incision size. The first retraction portion carries the first blade and includes tines each with ratchet grooves, while the second retraction portion carries the second blade on a carriage that is movably carried on the tines. Resilient spring actuated fingers associated with the carriage has ratchet grooves that co-act with the ratchet grooves of the tines to provide the ratchet assemblies between the retraction portions that regulates movement of the carriage and the second blade relative to the first blade.

A polyaxial ankle joint replacement implant has a dual bearing component situated between a tibia attachment component and a talus attachment component. The dual bearing component includes a plate, a superior bearing bonded to the plate and providing translation with the tibia attachment component, and an inferior bearing providing translation with the talus attachment component. The tibia attachment component has peripheral transversely extending flanges that limit movement relative to the superior bearing and vice versa. The plate has a flange on its inferior surface that receives an opening in the inferior bearing, the size of the opening determining an amount of lateral translation. The plate also has unobstructed posterior and/or anterior ends that permit removal and replacement of the inferior bearing post-operative. This allows change from a mobile to fixed bearing (and vice versa), as well as a change in amount of degrees of translation.

A semi-constrained polyaxial ankle joint replacement implant has a dual bearing component, a tibial component or plate adapted for attachment to a tibia or fibula bone, and a talar component or plate adapted for attachment to a 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. The tibial plate has peripheral transversely extending flanges that semi constrain or limit movement relative to the superior bearing and/or vice versa. The inferior bearing has a flange extending upwardly from the superior surface thereof that is received in an opening in the intermediate plate to semi constrain or limit movement relative between the two components.
