In order to position an ankle prosthesis including a tibial implant and a talus implant provided with a talo-calcaneal anchoring keel, the invention proposes a surgical instrumentation assembly including: a tibial phantom () of the tibial implant, adapted so as to be attached to the tibia (T) of a patient, and an aiming guide () adapted for setting into place an instrumentation element () through the talus (A) and the calcaneus (C) of the patient, along an axis (Z-Z) for implanting the talo-calcaneal anchoring keel, the tibial phantom and the aiming guide mechanically cooperating with each other to restrict movement of the tibial phantom and the aiming guide relative to each other along vertical and medio-lateral directions, wherein the aiming guide is configured to guide placement of the instrumentation element.

A construct is disclosed that may be used to repair or replace a natural ligament. The construct may be formed of materials for biocompatibility and/or resorbtion. The construct may be provided or connected to a soft anchor for connection to a bone portion.

A bone plate system is provided for joining together bone parts of a surgical patient. The system includes an elongated bone plate defining a longitudinal axis and having a first portion containing a first slot; a second portion containing a second slot; and a third portion containing a threaded hole. First and second compressing screws are provided for passage through the first and second slots and engagement into first and second respective bone parts. The compressing screws are configured to forcefully interact with the slots, and to urge the bone parts towards one another. A locking screw is provided for passage through the threaded hole and engagement into a third bone part.

The invention comprises a lateral ankle fusion plate, a jig for use with the fusion plate and a method for ankle fusion of the joints between the tibia, the talus, and the calcaneus. In addition, a separate fusion screw from posterior to anterior through the calcaneal tuberosity into the distal tibia is useful and can be placed using the targeting jig of the invention. The plate includes a C-shaped stirrup portion that wraps the bottom of the calcaneus and is provided with a screw hole for a T-T-C-fusion screw. A C-shaped targeting jig is provided that interfaces with the plate to allow for placement of the calcaneal screw and has an additional attachment for placement of the independent fusion screw so as to avoid impingement with the plate, and plate screws. The invention also relates to a method of surgery that incorporates the use of the plate, the jig and the tibial/talar/calcaneal fusion screw for an arthrodesis of the ankle joint.

A bone plate system for joining together adjacent bone parts of a surgical patient includes a bone plate having a first slot defining a first centerline axis, a second slot defining a second centerline axis, and a third slot defining a third centerline axis. The first, second and third slots are disposed in a triangular arrangement and simultaneously positionable over each of three adjacent bone parts. Each of a first compressing screw, a second compressing screw and a third compressing screw has a threaded shank for passage through the first, second and third slots, respectively, and engagement into the underlying bone part. Each of the first, second and third compressing screws also has a screw head configured to forcefully interact during insertion until fully seated with the first, second and third slot, respectively, thereby urging the first, second and third compressing screws to move along the first, second and third centerline axis, respectively, such that the three bone parts are multi-axially compressed towards each other.

Dorsal midfoot bone plate system and method

A method for joining together a first, a second and a third bone part of a surgical patient includes obtaining a bone plate having a first, a second and a third portion arranged along a longitudinal axis. The first portion contains a first slot for receiving a first compressing screw. The second portion is adjacent to the first portion and contains a second slot for receiving a second compressing screw. The third portion is adjacent to the second portion and contains a threaded hole for receiving a locking screw. The method further includes positioning the first, second and third portions over the first, second and third bone parts. The method further includes inserting the locking screw into the threaded hole and into the third bone part, inserting the second compressing screw into the second slot and into the second bone part, and inserting the first compressing screw into the first slot and into the first bone part, thereby urging the first, second and third bone parts together.
