A talar bone plate for use with a multi-component ankle prosthesis is disclosed that has a body having a medial side, a lateral side, an upper surface, a lower surface, a medial-anterior end, a lateral-anterior end, a medial-anterior portion that extends out in anterior direction beyond the lateral-anterior side, and a posterior side, where a length between the medial-anterior end and the posterior side is greater than the length between the lateral-anterior end and the posterior side near the lateral side of the body, where the body having at least one elongated screw hole provided in the medial-anterior portion and a plurality of screw holes provided in the area between the at least one elongated screw hole and the posterior side.

Talar bone plate

A talar implant includes a post projecting from a superior surface of the plate and includes at least one threaded hole. A talar dome having an inferior surface is configured to face the plate and an opening in the inferior surface is shaped to receive the post. The talar dome includes at least one through hole having a threaded surface and a groove. The groove has a larger outer diameter than the threaded surface. At least one fastener is configured to engage the threaded hole of the post and the threaded surface of the through hole. The at least one fastener has a groove that is aligned with the groove of the through hole when the fastener is inserted in the talar dome and the post. At least one clip is configured to engage the groove of the through hole of the talar dome and the groove of the fastener.

Talar dome with angled holes

A guided punch is disclosed. The guided punch generally comprises a strike cap comprising a strike surface, a punch comprising a distal cutting edge, and a guide rod. The strike cap defines a first cavity therein. The punch defines a second cavity therein in communication with the first cavity. The guide rod is located within the first and second cavities and extends a predetermined distance beyond the distal cutting edge of the punch. The strike cap and the punch are moveable relative to the guide rod.

Guided punch for talar augments

A revision implant component comprising a body having a plurality of screw holes and a tapered head configured to engage a talar dome component of a multi-component ankle prosthesis. A surgical method is disclosed which includes creating an incision in a patient, exposing a multi-component ankle prosthesis implanted in a patient, disassembling at least one component of the multi-component ankle prosthesis, affixing a revision implant component to non-damaged bone using screws, and coupling the revision implant component to a talar dome of the multi-component ankle prosthesis.

Revision implant augments, systems, and methods

The present subject matter relates to a geared instrument. The geared instrument is configured to translate rotation about a first axis to rotation about a second axis. The geared instrument comprises a handle configured to rotate about the first axis. A translation gear is configured to couple to the handle. A stem is coupled to the translation gear and rotates in unison with the translation gear. The translation gear is configured to translate the rotation of the handle about the first axis to rotation of the stem about the second axis. The stem is configured to couple to a modular head.

Geared instrument for tibial stem reaming or removal

A toe bone implant for correction of toe bone deformities is provided. The toe bone implant includes a first portion having a socket portion. The toe bone implant also includes a second portion having a ball portion operatively connected to the socket portion. The toe bone implant is implanted in a joint such that the ball portion is configured to rotate a predetermined amount respective to the socket portion.

Ball and socket implants for correction of hammer toes and claw toes

In some embodiments, a revision implant includes a body extending between a first planar surface and a second planar surface and a head extending from the first planar surface of the body. The head is configured to couple the revision implant to at least one additional component of a multi-component prosthesis. At least one coupling mechanism is configured to couple the body to a first bone.

Revision total ankle implants

In some embodiments, a surgical method includes creating an incision in a patient, exposing a multi-component prosthesis implanted in a patient, disassembling at least one component of the multi-component prosthesis, and coupling a first revision implant component to a first component of the multi-component prosthesis. The revision implant component has a body including at least one of a projection or an opening that is complementary to a feature of the first component of the multi-component prosthesis for coupling the revision implant component to the first component of the multi-component prosthesis.

A bone implant is disclosed. The implant comprises a body having a bone contact surface and an articulation surface. A first flange extends longitudinally from the bone contact surface. The flange defines a first screw hole configured to receive a targeted screw therethrough. The targeted screw couples the implant to a bone.
