Osteotomy cutting systems and surgical methods are provided herein. One surgical method includes coupling, to a cuneiform of a subject, a surgical apparatus for use in facilitating correction of a bunion and coupling the surgical apparatus to another bone of the subject. Another surgical method includes coupling a surgical apparatus to a cuneiform and metatarsal of a subject, coupling a cutting block for alignment at a joint between the cuneiform and the metatarsal, and performing a surgical procedure utilizing the surgical apparatus and the cutting block to correct a bunion. A further surgical method includes providing a surgical apparatus for use in facilitating correction of a bunion in a subject in which the surgical apparatus is configured to couple to a cuneiform and a metatarsal of the subject and performing a surgical procedure utilizing the surgical apparatus while the surgical apparatus is coupled to the cuneiform and the metatarsal.

A guidance tool includes a body having a length extending from a first end to a second end. The body includes a shape memory section along the length of the body. The shape memory section has a curved shape.

A system, includes a first screw mechanism including: a first block; a first screw threaded through the first block and including a first skin-interfacing portion; and an intramedullary (IM) member extending from and attached to the first block and including an end portion configured to be inserted into an intramedullary canal of a first bone fragment, wherein a first lateral force is generated between the first skin-interfacing portion against a second bone fragment, adjacent to the first bone fragment, and a holding force provided by the end portion when the first screw is rotated and the end portion is located in the intramedullary canal.

An assembly includes a first portion including an anchor pivotally attached to a first end of the first portion, the anchor to be inserted into an intramedullary canal of a first bone fragment; a second portion pivotally attached to a second end of the first portion and including a first skin-interfacing portion; a second skin-interfacing portion to interface with and secure the assembly to skin adjacent to the first bone fragment; and an actuation mechanism attached between the first portion and the second portion that actuates pivoting of the second portion to the first portion; wherein a lateral force is generated between the first skin-interfacing portion against a second bone fragment, adjacent to the first bone fragment, and a holding force is provided by the anchor when the actuation mechanism is actuated, so the first portion pivots with respect to second portion, while the anchor is in the intramedullary canal.

Provided is a prosthesis for ankle arthroplasty including a talar dome component configured to be attached to a talus bone. Also provided is a guide instrument for guiding a reamer to prepare a talus to receive the talar dome component.

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 device includes a first arm and a second arm. The first arm includes a first arm body that extends from a first end to a second end and a guide. The guide is rotatably coupled to the second end of the first arm body and is configured to be coupled to a first bone. The second arm includes a second arm body extending from a first end to a second end and is coupled to the first arm body such that it is rotatable with respect to the first arm body. The second arm is configured to engage a second bone. In use, rotation of the second arm body with respect to the first arm body changes the distance between the first bone and the second bone and rotation of the guide with respect to the first arm body rotates the first bone.

The disclosed subject matter relates to a visual guide for aiding the surgeon in the insertion of a k-wire. The guide including a ring for receiving a guide wire, the guide wire extending from the ring parallel to the center axis of the ring; and, a ring attachment mechanism configured to attach the visual guide to a wire driver. The guide wires representing the trajectory of the k-wire in two orthogonal planes thus allowing the surgeon to free hand the insertion by visually referencing the guide wires and the actual trajectory of the k-wire within the bone.

A surgical device includes a first body component including at least one insert embedded therein and a second body component including a patient-specific surface. The first body component includes a first material and the at least one insert includes a second material. The first body component defines at least one first hole and the second body component defines at least one second hole. The second body component is configured to be coupled to the first body component such that the at least one first hole and the at least one second hole are aligned when the first body component is coupled to the second body component to define at least one continuous fixation hole sized and configured to receive an elongate fixation device at a predetermined location.

Medical devices may include a patient-engaging section and an instrument-engaging section positioned on a body of the device and the methods of forming such devices. Medical devices described herein may include resection guides, resection guide locators, and/or instruments for use in surgical methods. Devices described herein may have sections that are complementary to a natural anatomical surface of a target area of bone of a predetermined patient. In some instances, a resection guide and resection guide locator may have portions configured to couple the resection guide to the resection guide locator. Resection guides and/or resection guide locators may include openings for receiving an instrument or tool during an operation on the predetermined patient target area of bone.
