Abstract: A surgical retractor (10) and method for retracting tissue in a patient is anatomically designed for particular muscles and includes a light source (16) the light beam (LP) of which is positionable relative to the surgical retractor. The surgical retractor (10) has a pair of retraction blades/arms (30, 60) carried on separate retraction portions (12, 14) held open by ratchet assemblies (100, 102). Blades (30, 60) are manually retracted and held open by automatically engaging ratchet fingers (52, 53) and are designed to match muscle curvature, minimizing various risks and incision size. The first retraction portion (12) carries the first blade (30) and includes tines (20, 21) each with ratchet grooves (24, 25), while the second retraction portion (14) carries the second blade (60) on a carriage (46) that is movably carried on the tines (20, 21). Resilient spring actuated fingers associated (54, 55) with the carriage (46) has ratchet grooves (80, 81) that co-act with the ratchet grooves (24, 25) of the tines (20, 21) to provide the ratchet assemblies (100, 102) between the retraction portions that regulates movement of the carriage (46) and the second blade (60) relative to the first blade (30).

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.
