20080208349 | Expandable subtabar implant - An expandable subtalar implant device suitable for addressing a flatfoot condition. The device is a sinus tarsi implant that blocks excessive motion between the talus and calcaneus bones in the foot while permitting normal motion and alignment. The device comprises a generally cylindrical metal structure having a first proximal expandable end and a second distal adjustment end. A first component of the implant forms each of the cylindrical end sections and a second component comprises a movable internal rod that serves to progressively expand the outer cylinder of the implant. The internal rod is externally threaded and mates with internal threading on the cylindrical outer component. Progressive turning of the internal rod engages a number of radially arranged inclined surfaces that form the interior walls of the cylindrical shell component. Progressive engagement of the rod with these inclined surfaces forces the end of the cylindrical shell component outward; expanding the overall diameter of the implant once it has been positioned within the sinus tarsi. | 08-28-2008 |

20150320567 | Total Ankle Replacement Prosthesis - A total ankle replacement prosthesis may comprise a tibial implant, a talar implant, and an intermediate implant. The intermediate implant may fixedly attach to the tibial implant and may articulate with respect to the talar implant. The intermediate implant may have unequal front and back angular extent, so as to discourage a particular direction of subluxation, and a kit may be provided containing various such intermediate implants. Various features may be provided in regard to dovetails, fins, recesses, the placement of fins and pegs, and the shape of the perimeter of the tibial implant. Recesses may allow a surgical blade to slice a latch off of an already-installed intermediate implant, in order to allow its removal from the tibial implant. | 11-12-2015 |
