    Abstract: A subtalar joint prosthesis (1) that is adapted to replace the natural subtalar joint that exists between a patient's talus and calcaneus bones includes talar (2) and calcaneal (4) components. Each of these is configured to have a shape that is herein defined as being a portion of the boundary surface of a frustum. Meanwhile, these components' inner (8, 28) surfaces are configured to: (a) generally follow the anatomic contour of the original joint surface to which each component is to be attached, and (b) minimize each component's average thickness, consistent with providing sufficient strength and rigidity for the components, so as to require minimum bone resection for the implantation of these components.

    Abstract: A first implant (102) may be configured for attachment to a talus bone (101). A second implant (106) may be configured for attachment to a calcaneus bone (105). The first implant (102) attached to the talus bone (101) can move in relation to the second implant (106) attached to the calcaneus bone (105). A sheet (104) can be disposed between the first implant (102) and the second implant (106) to facilitate relative motion between the first implant (102) and the second implant (106). The sheet (104) may provide a curvilinear surface (1 18) that engages a curvilinear surface (1 14) of the first implant (102) or a curvilinear surface of the second implant (106) to facilitate the relative motion. A set of tools (144) may be used to distract the talus bone (101) from the calcaneus (105), which may be used for insertion of the implants (102, 106).

    Abstract: A subtalar joint implant (20) is disclosed for replacing a natural subtalar joint existing between the talus (102) and calcaneum (104) bones of a patient. In an embodiment the implant comprises talar (22) and calcaneal (24) portions that are configured to slide over each other in the implanted state. The implant is shaped so that the sliding is constrained to trajectories that involve pivoting of the talar portion relative to the calcaneal portion about a pivot point (36) or a line (38) of pivot points.

    Abstract: A prosthesis including a magnetic implant approximating the size of a bone to be replaced; a first magnetic bone implant securable to a first bone adjacent the bone to be replaced; and a second magnetic bone implant securable to a second bone adjacent the bone to be replaced. Each of the first and second magnetic bone implants have a magnetic relationship with the magnetic implant. A method of reconstructing a wrist includes removing a patient's scaphoid to create a void. The scaphoid has a plurality of adjacent bones, each of the adjacent bones comprising a surface generally facing the void. The surface of at least two of the adjacent bones is prepared by affixing a magnetic element thereto and a magnetic scaphoid implant is inserted into the void. A magnetic relationship exists between the magnetic elements and the magnetic scaphoid implant.
