A manufacturing method of a sliding member for an artificial joint according to the present disclosure includes exposing a base member with ultraviolet rays in a state where the base member is in contact with an aqueous treatment solution containing a compound having 0.20 mol/L or more and less than 0.50 mol/L of phosphorylcholine group and a water-soluble inorganic salt.

A system and related method for eliminating microbes from a metal orthopedic appliance includes a counter electrode and working electrode used for applying treatment, and a reference electrode used for monitoring safety parameters. The working electrode is the implanted appliance. Electrical current is applied between the counter electrode and the working electrode to create electrochemical current through the system and create electrochemical reactions on the surface of the working and counter electrode. The chemical species created at the working electrode provide a mechanism to disrupt and kill microbes on that surface, including bacterial biofilms commonly found on infected orthopedic implants. Circuitry connected to the electrodes keeps the applied current constant and allows the voltage between the working and counter electrode to vary. The reference electrode monitors the voltage at the working electrode in order to provide feedback to a processor as part of a feedback mechanism. The processor is programmed with software logic, preventing the voltage from drifting to ranges that correlate with metal immunity or corrosion regions by limiting or altering the applied current.

A ceramic monobloc femoral component (10) is provided for a total hip replacement prosthesis. The ceramic monobloc femoral component (10) has a ceramic femoral stem (14) and a ceramic head (12) which defines a part-spherical articular surface receivable by an acetabular cup (56). The ceramic femoral stem (14) and the ceramic head (12) are integrally formed as one-piece.

An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.

The application is directed to devices and methods where one or more magnetic or magnetizable implants provides therapeutic benefits to a patient. The implant may be useful for expanding the range of motion of joints or dynamically providing different responses to changing conditions in the body where the implant is placed. An electromagnet is placed on or in a bone on one side of a joint, and another electromagnet or magnetically active material is placed on or in a bone on the opposing side of the joint. The electromagnet may be continuously energized to relieve pressure in the joint space, or may be energized in response to forces applied to the joint.

Devices and methods for use in a hip replacement surgical procedure. One aspect includes methods and devices for reaming selective regions of the femoral canal. This may include reaming distal and proximal sections of the femoral canal prior to reaming a middle region of the canal. Another aspect includes a dummy implant and methods of use. The dummy implant is inserted into the femoral canal and may be used for one or more of retraction of the femur, gauging a space with the acetabulum, and further revising the femoral cut. The aspects may be used together in a single surgical procedure or separately in different surgical procedures.

An ultrasound measuring device includes: a support bearing two ultrasound probes movable relative to each other by slide link, each of the two probes being movable relative to the support by ball-joint link, wherein the probes are capable of simultaneously acquiring two ultrasound images. The device includes a first set of measuring elements to measure a relative positioning of the probes, including one travel sensor and at least two orientation sensors. The device includes a second set of measuring elements to measure a positioning of the device relative to a reference plane, including at least one orientation sensor. The device localizes at least one point of interest on each of the two ultrasound images, and processes data coming from the first and second measuring elements, delivering a relative spatial position of the points of interest located in the images.
