A novel and improved elbow prosthesis and method of implanting same including a novel aggregate prosthesis having a retaining system in conjunction with a set plate.

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.

Devices and methods are provided that simplify and improve placement of stabilizing orthopedic pins, wires, and/or screws in the pelvis in minimally invasive surgery. Provided is a surgical instrument guide containing an adjustable friction clamp for positioning and securing a cannula, and a probe with a blunt, nonpenetrating tip. The probe and a surgical instrument held by the friction clamp are oriented at right angles to one another. In use, the blunt probe is introduced through a small incision and advanced by blunt dissection until the blunt tip is positioned at a desired anatomical landmark on the surface of the pelvis. A cannula inserted through the friction clamp is advanced until the tip of the cannula is within 2 cm of the blunt tip of the probe; an orthopedic pin, wire, and/or screw can then be inserted through the cannula to provide stabilization. The blunt probe may be cannulated.

A nail for compressing two bone parts to treat bone fractures or osteotomies is provided. The nail has an elongate smooth portion and an elongate threaded portion that is constructed for generating axial compression along a length of the elongate threaded portion between two bone parts. The nail may also have one or more apertures for installing one or more crossing screws through the nail. An installation instrument particularly constructed to install the provided nail is provided. A first and second portion of the provided nail installation instrument may rotate relative to one another when a locking mechanism is disengaged, but are locked in position relative to one another when the locking mechanism is engaged, which enables installation of the provided nail.

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.

An anchoring system for cannulas or tools to be inserted into a surgical workspace in the body, particularly the brain, of a patient. The system comprises a grommet which may be fixed to the skull to both secure the system to the skull and protect the skull opening from passage of cannulas and tools, a resilient clip with grasping jaws adapted to firmly grasp a cannula or tool, and a flexible membrane secured to the outer rim of the grommet and the clip.

A method of preparing a tarsometatarsal joint can include imaging a tarsometatarsal joint of a patient between a metatarsal and a cuneiform to determine a size and/or angle of a wedge-shaped bone portion to be cut at the tarsometatarsal joint. The method can include obtaining a bone preparation guide that includes a first guide surface positionable over the metatarsal and a second guide surface positionable over the cuneiform, where an angle of the first guide surface relative to the second guide surface is selected corresponding to the size and/or angle of the wedge-shaped bone portion to be cut as determined via imaging of the tarsometatarsal joint. The method can include positioning the guide surfaces over the metatarsal and cuneiform and guiding a tissue removing instrument with the guide surfaces to cut an end of the metatarsal and to cut an end of the cuneiform.

An implant resection system for preparing an implant site to replace a defect in an articular surface of a first bone includes a first guide configured to be coupled generally to the first bone. The first guide includes a body portion defining a channel configured to receive a pin, wherein the pin is configured to penetrate and form a longitudinally disposed bore within the first bone. The implant resection system further includes a second guide configured to be coupled generally perpendicular to the first bone proximate to the defect by way of the bore. The second guide includes a drill bit configured to form an excision site through a portion of the articular surface in preparation of receipt of an implant.

Described are fibula malleolus caps and surgery devices with fibula malleolus caps. The fibula malleolus caps may be patient-specific fibula malleolus caps. The devices with patient-specific fibula malleolus caps overcome the sliding and rotational errors during fibula flap harvesting. A comparative clinical study demonstrates that the fibula malleolus cap enhances the accuracy of fibula flap harvesting, leading to accurate location and angulation of simultaneous dental implants.
