Abstract: A prosthesis may include a first component, a second component, and a coupling member. The first component may include a first body extending from a first end to a second end, which may define a first opening that extends inwardly toward the first end. The first opening may include a first portion having a first diameter and a second portion having a second diameter. The second component may include a second body extending from a first end to a second end. The second body may define a second opening that extends through the second body. The coupling member may be configured to couple the first component and the second component by compressing the first component and the second component. The coupling member may include a shaft portion and a head portion. The shaft portion may be sized and configured to be received in the first opening and the second opening.

Abstract: An alignment guide includes a base, a swing arm for coupling to the base such that the swing arm is movable relative to the base, and a locking device for selectively fixing a position of the swing arm relative to the base. The base defines at least one first hole sized and configured to receive a first fixation element and defines at least one second hole sized and configured to receive a second fixation element. The swing arm extends from a first end to a second end. The second end of the swing arm including a coupling mechanism for coupling another guide to the second end of the swing arm. Methods also are disclosed.

Abstract: A cutting guide includes a body extending between an upper surface and a lower surface and defined by a perimeter. The cutting guide further includes a guide foot having a contact surface. A guide element is pivotably coupled to the body. A handle extends from a first end to a second end. The first end is configured to be coupled to the body.

Abstract: A surgical device includes a housing, a cannula, a driving handle, and a cutting blade. The housing defines a hole in which the cannula that defines a passageway extending from a distal end to a proximal end is disposed. The driving handle is movably coupled to the housing and includes a driving rod slidably received within the passageway. The cutting blade is disposed within the passageway of the cannula and includes a distal end coupled to the distal end of the cannula, a proximal end configured to engage a distal end of the driving rod, and a reversibly deformable blade region disposed between the distal and proximal ends of the cutting blade. The deformable blade region is sized and configured to be received within at least one slot defined by the cannula and bends and straightens in response to movement of the driving handle relative to the housing.

Abstract: A talar dome is provided as an element of a total ankle arthroplasty, to fit over a resected talus bone. The talar dome has an integral dome body with a smooth and rounded superior articulating side facing the tibia, and an inferior mounting side with mutually inclined flat faces that complement the flat surfaces of the resected talus. On the inferior or mounting side, the talar dome has at least two pegs integral with and rigidly protruding from the dome body. The pegs each taper along flat faces to a point that is embedded in the talus bone for operatively attaching the talar dome to the talus bone. At least one flat face is of each peg is perpendicular to the sagittal plane and resists anterior/posterior displacement of the talar dome until healed.
