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 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 system comprised of custom radiographically designed tibial and talar cutting guides, a tibial reaming guide and bit, and instrumentalities for use in total ankle replacement surgery and a computer-based system and method for making the custom radiographically designed tibial and talar cutting guides.

An osteotomy implant device includes a housing defining a cavity and having a central plane extending therethrough. The housing includes a first bone engaging surface and a second bone engaging surface. The second bone engaging surface disposed on an opposing side of the central plane from the first bone engaging surface. The osteotomy implant device also includes a cutting member. The cutting member rotatable coupled to the housing. The cutting member rotatable about an axis between a first position and a second position. The cutting member entirely disposed within the cavity between the first bone engaging surface and the second bone engaging surface in the first position. A portion of the cutting member extends beyond at least the first bone engaging surface or the second bone engaging surface of the housing in the second position.

Disclosed is a device for assisting in the placement of a trapeziometacarpal prosthesis including a cup to be fixed in the trapezium of a patient and a stem to be fixed in the patient's first metacarpal. The device includes a first guide to be interposed between the trapezium and the first metacarpal, the first guide including a first body having a first surface to be positioned on the articular surface of the trapezium, the first surface congruent with the articular surface of the trapezium and a second surface to face the articular surface of the first metacarpal before resection, the second surface preferably being congruent with the articular surface of the first metacarpal so as to be positionable on the articular surface of the first metacarpal. The first guide also includes locating members carried by the first body and arranged to define resection lines for the first metacarpal.

Methods of implanting a talar component during ankle surgery are provided. A method includes cutting at least medial and lateral cuts in a talus bone. The method includes driving a first self-cutting distal edge of a lateral side wall of the talar component into the lateral cut and a second self-cutting distal edge of a medial side wall of the talar component into the medial cut. A thickness of the lateral sidewall tapers to form the first self-cutting distal edge and a thickness of the medial sidewall tapers to form the second self-cutting edge.

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.

Techniques for implantable orthopedic pain management devices are disclosed, including incising an opening in a synovial capsule substantially surrounding a joint, using a first tool to form an enlarged opening in the synovial capsule, determining whether to modify the joint, the joint being modified using a second tool if a bone structure coupled to one or more bones is found within the joint and the bone structure is configured to limit articulation of the one or more bones when an implantable device is inserted into the synovial capsule and the joint, and inserting the implantable device into the synovial capsule through the enlarged opening, the implantable device being inserted into the joint using a third tool.

Techniques for implantable orthopedic pain management devices are disclosed, including a saddle configured to axially align a top contoured surface to a bone surface and to axially align a bottom contoured surface to another bone surface, and a peripheral protrusion disposed on a peripheral surface of the saddle, the peripheral protrusion being configured to maintain dynamic stability of the saddle between the bone surface and the another bone surface.

A device for use during an arthroplasty procedure of a joint of a patient, the joint extending between a first joint end of a first bone and an abutting second joint end of a second bone of the patient. The device includes first and second components that can be mated together. The first component includes an attachment fitting configured for disposing over the first joint end of the first bone and a stem extending from the attachment fitting and suitable for extending along an intra-medullary canal of the first bone. The second component includes an end plate configured to mate with the attachment fitting and a longitudinal plate extending from the end plate and configured for disposing along a medial, longitudinal surface of the first bone. The device also includes at least one fastener for coupling the longitudinal plate to the first bone.

An alignment guide for total ankle replacement surgery and a method of creating and using the alignment guide. The alignment guide has a surface that interfaces with a corresponding surface of a superior aspect a talus of a patient, and as second surface portion that interfaces with a corresponding distal surface of a section of a tibia of the patient. When the alignment guide is in position, it maintains the ankle of the patient in a preselected position.
