An adjustment compliance device and systems and methods for use with an external fixator are disclosed. The adjustment compliance device can be attached to a strut of an external fixator and may include at least one indicator element to indicate adjustment parameters for an active step of an adjustment process for the external fixator. The adjustment parameters may include an active strut and/or a direction of adjustment for the strut. The adjustment compliance device may receive the adjustment parameters from a user device. The at least one indicator element may include a light element operative to emit light in a color corresponding to the active strut. The at least one indicator element may include a light element configured to indicate a direction of rotation of the active strut. As a result, a patient can more effectively comply with an adjustment prescription, thereby improving the likelihood of successful bone alignment.

Device for indicating an active component of an adjustable medical apparatus

A strut measurement and feedback device and corresponding systems and methods for use with an external fixator are disclosed. The strut measurement and feedback device can be attached to a strut of an external fixator. The strut measurement and feedback device can confirm that the strut measurement and feedback device is attached to a proper strut to be adjusted. The strut measurement and feedback device can provide real-time feedback to an individual as the length of the strut is being adjusted to ensure the length adjustment complies with a prescription for the length of the strut. As a result, a patient can more effectively comply with the prescription as adjustments to the strut are made over time, thereby improving the likelihood of successful bone alignment.

Device for external fixation strut measurement and real-time feedback

A system () for identifying a landmark is disclosed. The system includes a field generator () for generating a magnetic field, an orthopedic implant () located within the magnetic field, the implant having at least one landmark (), a removable probe () with a first magnetic sensor (), a landmark identifier () with a second magnetic sensor () and a processor () for comparing sensor data from the first and second sensor and using the set distance to calculate the position of the landmark identifier relative to the at least one landmark. The system allows for blind targeting of one or more landmarks.

System and method for identifying a landmark

A system for targeting landmarks on devices such as surgical implants is disclosed. The system can include a field generator for generating one or more magnetic fields, an orthopedic implant located within the magnetic fields, the implant having at least one landmark, a removable probe with a first magnetic sensor, a landmark identifier and a processor. The landmark identifier can contain a second sensor, or, alternatively, the field generator. The processor can utilize sensor data and, if desirable, field generator and other information, to generate and display the position and orientation of the sensor(s) in preferably six degrees of freedom, and thereby, to generate and display the position and orientation of the landmark(s). The system allows for blind targeting of one or more landmarks. The landmark identifier, field generator and/or drill motor may be disposed in an autoclavable housing.

Targeting an orthopaedic implant landmark

A system () for identifying a landmark is disclosed. The system includes a field generator () for generating a magnetic field, an orthopaedic implant () located within the magnetic field, the implant having at least one landmark (), a removable probe () with a first magnetic sensor (), a landmark identifier () with a second magnetic sensor () and a processor () for comparing sensor data from the first and second sensor and using the set distance to calculate the position of the landmark identifier relative to the at least one landmark. The system allows for blind targeting of one or more landmarks.

Targeting sensors for use in targeting landmarks of orthopaedic devices. The sensors include a non-cylindrical mounting platform such as a printed circuit board and at least two mounted or printed sensor coils to provide a low profile sensor assembly which can be placed in a predetermined position and orientation on or in an orthopaedic device. The platform has a non-circular cross-section having an aspect ratio of greater than about 1.5:1. The non-circular cross-section of the platform enables the sensor to be placed in a known fixed position within the implant. The sensor coils may be partially or fully embedded in the platform.
