The invention relates to a method and a device for determining an incorrect positioning in the alignment of prostheses for the lower extremities, said method comprising the following steps: determining inertial measurement data and/or variables derived therefrom by means of at least one inertial sensor, over at least one walking cycle, for an extremity provided with a prosthesis; and comparing the inertial measurement data that has been determined and/or the variables derived therefrom with desired values and/or with measurement data that has been determined or variables derived therefrom for the corresponding extremity that is not provided with the prosthesis.

Various systems and methods are provided for surgical and interventional planning, support, post-operative follow-up, and functional recovery tracking. In general, a patient can be tracked throughout medical treatment including through initial onset of symptoms, diagnosis, non-surgical treatment, surgical treatment, and recovery from the surgical treatment. In one embodiment, a patient and one or more medical professionals involved with treating the patient can electronically access a comprehensive treatment planning, support, and review system. The system can provide recommendations regarding diagnosis, non-surgical treatment, surgical treatment, and recovery from the surgical treatment based on data gathered from the patient and the medical professional(s). The system can manage the tracking of multiple patients, thereby allowing for data comparison between similar aspects of medical treatments and for learning over time through continual data gathering, analysis, and assimilation to decision-making algorithms.

A medical system comprising a patch device and a computer. The patch device is in communication with the computer. The patch device is configured for generating measurement data or providing a therapy. The patch device comprises electronic circuitry, a battery, an antenna system, one or more sensors, an IMU (inertial measurement unit), and a flexible enclosure. The antenna system can comprise a dual antenna formed on a dielectric substrate with a first antenna on a first side of the dielectric substrate and a second antenna on a second side of the dielectric substrate. The one or more sensors can comprise devices configured to provide measurement data or a therapy. The IMU is configured to measure position, movement, and trajectory of the patch device. The electronic circuitry is configured to harvest energy from one or more radio frequency signals received by the antenna system to recharge the battery.

A method for assessing the orthopaedic performance of a joint of a patient can comprise implanting at least a first and second RF wirelessly detectable markers in first and second bones associated with a site and determining and storing their positions before a surgical procedure is performed. The procedure can be carried out on the site and the positions of the first and second markers can be detected and stored after the procedure has been completed. The detected positions can be used to generate a representation of the orthopaedic performance of the joint after the procedure.

Within examples, a surgical device with an embedded sensor system for performing hip replacements is described. This device mitigates fracturing of the mid metaphyseal/diaphyseal region of the femur, and ensures adequate press-fit of the component into the bone. The device relays information regarding forces experienced by the patient's bone to a separate data acquisition device and displays it on an interface. This information is used by the surgeon to determine the force present inside of the patient's bone during broaching, and can then be used to provide better care, and mitigate fractures due to overloading in the bone.

Apparatus, system, and method are disclosed herein for controlling movement of an artificial orthopedic joint prosthesis in a mammalian subject. The apparatus, system, or method includes an orthopedic brace configured to control movement of an orthopedic joint prosthesis. The apparatus, system, or method includes one or more sensors and one or more controllers in communication with the one or more sensors. The one or more sensors are configured to detect a change in an orientation of a subject's position in an environment and configured to detect one or more alignment orientations of the orthopedic joint prosthesis.

The present invention is a responsive exercise device comprising a base having a first end and a second end, wherein the base has a plurality of compartments, a plurality of measurement sensors, a plurality of support panels secured to the base over the first set of the plurality of compartments, a plurality of positioning rails secured to the plurality of support panels, wherein the positioning rails have a plurality of openings sized to fit a bearing, a plurality of bearings positioned within the openings of the plurality of rails and between the support panels, wherein the plurality of bearings are retained in the openings and freely rotate; a first spring assembly positioned distal to the first end of the base, a second spring assembly positioned distal to the second of the base comprising, a plurality of plates positioned over the plurality of bearing assemblies and mechanically.

Systems and methods for monitoring a range of motion of a joint are described. For example, in one embodiment, a first set of sensors may sense accelerations of a first body portion located on a first side of the joint and a second set of sensors may sense accelerations of the second body portion located on a second opposing side of the joint. The acceleration data may then be used to compute the relative motion of the first and second body portions to determine movement of the joint. This joint movement may then be used to determine one or more range of motion movement metrics which are output for viewing by a subject or medical practitioner.

The present disclosure includes systems and methods for deriving certain characteristics of the patient's body related to motion from captured motion data. The characteristics may be used to compare the characteristics of the supposed injury to the characteristics of a normally functioning body part as well as the functions of an injured body part. The present disclosure provides a reliable and reproducible way to determine whether a supposed injury is a feigned or exaggerated injury or an actual injury.
