An arthrodesis anchor as a monolithic piece has prongs supporting barbs extending radially therefrom. A neck between the ends may be angled to accommodate final alignment of resected surfaces of joints to be bonded. The neck may receive a tool for buttressing a first inserted end against further penetration into a joint while the second inserted end is inserted into the other adjacent joint. The proximal and intermediate phalangeal joints may be trimmed and pilot drilled, and may be broached with or without a K-wire guide. A first end may be inserted by a tool, typically into the proximal joint, but the order may be reversed. The second end may then be inserted into a pilot in the base of the intermediate joint.

Various surgical devices and methods are disclosed herein. Also disclosed is multi-component prosthesis, which can be used as an ankle prosthesis. One of the disclosed surgical alignment systems includes a guide arm, a ratchet arm frame configured to be coupled slidably to the guide arm, a ratchet arm configured to be coupled to the ratchet arm frame, and a sagittal sizing guide body configured to be coupled to the ratchet arm. The sagittal sizing guide body includes a first radiopaque object disposed at a first position and a second radiopaque object disposed at a second position that is spaced apart from the first position.

A device comprises a base. A support is attached to the base. The support is shaped to receive a calf of a person and adapted to receive a wire or pin for securing a tibia of a person. A foot plate is attachable to the base. The foot plate has a plurality of attached members. The members are configured for receiving at least a first wire or pin to fix a foot of the person relative to the foot plate while the foot plate is oriented normal to a superior-inferior direction of the foot. The foot plate is rotatable relative to the base while the foot plate is attached to the base.

A position adjustment device having a tool holder is locked to at least two pins projecting from respective anterior facing locations near a distal end of a tibia of a patient. The position adjustment device is adjusted. The position adjustment device is locked with the tool holder at first coordinates in the proximal-distal and medial-lateral directions. The distal end of the tibia is resectioned with a tool positioned on the tool holder, while the tool holder is in the first coordinates in the proximal-distal and medial-lateral directions. The tool is removed from the tool holder. A tibia trial is placed on the resectioned tibia using the tool holder, while the tool holder is in the first coordinates in the proximal-distal and medial-lateral directions. The tibia trial has a size and shape of a tibial tray of an ankle replacement system.

Resection guides include a body a plurality of alignment pin through-holes and a plurality of guide through-holes so that the pattern of guide through-holes is operable for receiving a drill for use in resecting the at least a portion of the anatomical structure of the patient. Sweeping reamers include a body having a plurality of alignment pin through-holes and an elongated opening, and a reamer extendable through the elongated opening of the body. Decoupled resection guides include a first body having a plurality of alignment pin through-holes and a second body having a plurality of fixation pin through-holes and at least one guide aperture operable for guiding a cutting tool for use in resecting a portion of the second anatomical structure of the patient. Methods employing the same are disclosed and operable in, for example, total ankle replacement.

An innovative dome toe resurfacing system for performing metatarsophalangeal joint replacement is disclosed. The present invention comprises a prosthetic implant for metatarsophalangeal joint, and one or more cone extensions that covers portions of the prosthesis that extends into the metatarsal bone and phalanx bone. The cone extensions include a plurality of ridges that will catch bone on insertion and provide a press fit. The present invention also includes a cone and cup reaming system wherein one or more reamers will ream a cone/cup shape for the articular surfaces, and prepare the metatarsal and phalangeal canals for the insertion of the cone extensions. The cone extensions have ends that fit the reamed cone/cup shape wherein the cone/cup shape resembles the natural anatomy of articular surfaces of metatarsophalangeal joint.

Devices and techniques for adjusting an alignment for a first metatarsal may include making a plurality of cuts along the length of the first metatarsal. In different applications of the technique, a plurality of transverse cuts may or may not be made intersecting the longitudinal cuts. In either case, the cuts can separate the first metatarsal into two individual portions and release a removable wedge of bone. The different portions of the metatarsal can be moved relative to each other to adjust an anatomical alignment of one portion relative to another portion, for example in multiple planes. After suitably adjusting the alignment of the different bone portions, the portions can be fixed together.

Illustrative embodiments of orthopedic implants and methods for surgically repairing hammertoe are disclosed. According to at least one illustrative embodiment, an orthopedic implant includes a proximal segment comprising a number of spring arms forming an anchored barb at a first end of the implant, a distal segment extending between the proximal segment and a second end of the implant, and a central segment disposed between the proximal and distal segment.

Instruments and techniques can be used to release a first metatarsal for realignment. In some implementations, a techniques involves surgically accessing a sesamoidal ligament in a foot of a patient and advancing a guiding projection of a cutting instrument under the sesamoidal ligament. This can capture the sesamoidal ligament between the guiding projection of the cutting instrument and a cutting surface of the cutting instrument that is recessed relative to a distal end of the guiding projection. The techniques further involves cutting the sesamoidal ligament with the cutting surface of the cutting instrument.

An orthopedic cutting instrument can be used to cut and release soft tissue to mobilize a bone for subsequent realignment of the bone. In some examples, the cutting instrument is configured with a handle and a cutting head. The cutting head has multiple cutting surfaces, such as a lead cutting surface and side cutting surfaces extending angularly away from the lead cutting surface. A mirror set of cutting surfaces may be provided on the opposite side of the cutting head. The cutting surfaces may be arranged to allow controlling cutting of soft tissue while limiting inadvertent deep penetration of the cutting instrument. In addition, the cutting surfaces may be arranged to allow back-and-forth cutting movement of the cutting head, which can be useful when working in a tight joint space.
