Abstract: An arthroplasty trial assembly for a human shoulder can include a first implant securable to a first bone and a second implant securable to a second bone. The second implant can include a body, a stem, an articulation component, and a sensor. The stem can extend from the body, and the stem can be insertable into the second bone. The articulation component can be coupled to the body opposite the stem, and the articulation component can be articulable with the first implant. The sensor can be connected to the articulation component and can be configured to monitor a condition of the second implant and can produce a sensor signal as a function of the condition that is indicative of stability of the shoulder.

Abstract: Embodiments of a system and method for assessing hip arthroplasty component movement are generally described herein. A method may include receiving data from a sensor embedded in a femoral head component, the femoral head component configured to fit in an acetabular component, determining information about a magnetic field from the data, and outputting an indication of an orientation, coverage, or a force of the femoral head component relative to the acetabular component.

Abstract: A bone implant includes a rod having an aperture extending entirely through the rod. The aperture is to receive a fastener to couple the rod to a bone of a patient. The bone implant also includes a light source disposed on the rod. The light source is to emit light onto a portion of the bone adjacent the rod to at least one of stimulate bone growth or reduce bone loss.

Abstract: A joint replacement balancing system which provides real-time feedback to a surgeon during a joint replacement surgery to assist the surgeon to balance a joint replacement. The joint replacement balancing system includes a non-transitory processor-readable medium storing code representing instructions to cause a processor to receive a signal from a joint balancing apparatus, determine if the joint replacement is out of balance, determine a corrective course of action to bring the joint into balance and generate and display to the surgeon during the joint replacement surgery a recommended corrective course of action to complete the joint replacement surgery.

Abstract: According to some embodiments, systems and methods for reshaping bone are provided. The systems may include an implant body, an actuator coupled to the implant body, a sensor configured to detect a parameter indicative of a biological condition, a transceiver, and a controller. The transceiver may be configured to transmit data associated with the parameter to an external remote control and receive instructions from the external remote control. Finally, the controller is configured to move the actuator in response to the instructions from the external remote control, wherein the actuator adjusts the implant body. The methods may include measuring a parameter indicative of a biological condition; transmitting data associated with the parameter from the implantable device to an external remote control; transmitting instructions from the external remote control to the implantable device; and actuating the bone growth device in response to the instructions from the external remote control.

Abstract: An endoprosthesis is proved which includes an elongate housing having a drive secured through a threaded drive shaft to an extension shaft therein, the drive operable to cause the extension shaft to move axially with respect to the body, and the extension shaft and housing configured to be securable to a bone to act as a prosthetic replacement for removed bone. An operating system for the endoprosthesis is also provided.

Abstract: An implantable device includes at least one solid structure having an external surface and a volume beneath the surface. One or more of a first conductor or set of conductors is disposed externally and/or internally on or within the structure and an array of elongate electrically conductive elements are disposed radially outwardly within the volume. A breach is detected when a conductive fluid intrudes into the volume through the surface.

Abstract: A method of determining patient follow-up subsequent to an orthopaedic procedure includes determining the number of cycles of use of an orthopaedic joint of the patient. If a predetermined threshold is exceeded, communication with an orthopaedic care provider is initiated. A patient monitoring system is also disclosed.

Abstract: An implantable, adjustable prosthesis includes a first component which may be moved relative to a second component by use of a transcutaneous control signal. A method of operating such a prosthesis is also disclosed.

Abstract: An orthopedic device adapted for implantation into a body where it contacts bone tissue is disclosed which has at least one spaced apart polarized magnetic element, at least one piezoelectric element or a combination of a polarized magnetic element and a piezoelectric element which are in direct contact with one another or are separately mounted on the implant. The piezoelectric element being at least partially embedded in a surface of the device which contacts bone tissue for the promotion of osteogenesis or osseointegration.

Abstract: A prosthetic implant system connected to the tissue of a living organism. The system contains a first device for measuring the mechanical strain in the implant in an area thereof which is not exposed to tissue regrowth, a second device for measuring the mechanical strain in the implant in an area thereof which is exposed to tissue regrowth, a device for continuously determining the stress/strain relationship of said implant, and a device for treating said tissue.

Abstract: The invention relates to a joint endoprosthesis and a method for fixing the seat thereof. The endoprosthesis has a shaft that is anchored in the marrow cavity of a tubular bone, and an ultra source that is placed in or on the shaft and the radiation characteristics of which enable ultrasound waves to reach a gap between the spongiosa of the tubular bone and the surface of the external covering of the shaft. The associated method applies impinging ultrasound waves upon the gap.
