Abstract: A system and method for transmitting implant data includes an orthopaedic implant, a wireless receiver, and a processing circuit electrically coupled to the wireless receiver. The orthopaedic implant is configured to transmit implant identification data and implant sensor data to the wireless receiver in response to a power signal. The orthopedic implant may transfer the data over, for example, a wireless network. The processing circuit receives the implant identification data and the implant sensor data from the wireless receiver and is configured to retrieve patient-related data from a database based on the implant identification data. The processing circuit may also be configured to update a patient queue, assign a patient room to a patient, and/or transmit the patient-related data and the implant sensor data to a client machine located in the patient room.

Abstract: A method for determining a position of a magnetic source includes measuring a magnetic field generated by the magnetic source and determining components of the three-dimensional magnetic flux density of the magnetic field at a plurality of points in space based on such measurement. The method also includes estimating a position of the magnetic source and determining components of a theoretical three-dimensional magnetic flux density at the plurality of points in space based on the estimated position. The position of the magnetic source may then be determined by minimizing the difference between the components of the measured and corresponding theoretical three-dimensional magnetic flux density components.

The orthopaedic surgical instrument also includes a user-operated control device operable to actuate the orthopaedic distraction device to apply force between the patient's femur and the patient's tibia. In actuating the orthopaedic distraction device, a rotary input of the user-operated control device that is coupled to the orthopaedic distraction device may be used. The orthopaedic surgical instrument also includes a display positioned on an outer surface of the orthopaedic distraction device and a circuit configured to control the display. The display is configured to provide visual feedback indicative of force applied by the distraction device.

Abstract: A system and method for managing inventories of orthopaedic implants includes receiving a medical image of a bone of a patient from a healthcare provider, performing a digital templating procedure on the medical image to determine an orthopaedic implant for use with the bone of the patient; transmitting the digital templated medical image to the healthcare provider, and shipping the orthopaedic implant to the healthcare provider in response to an electronic approval of the digital templated medical image received from the healthcare provider. Implant constraint data may also be received from the healthcare provider and used in determining the orthopaedic implant. In addition, a number of orthopaedic implants having a range of different sizes based on the size of the determined orthopaedic implant may be shipped to the healthcare provider. In some embodiments, the healthcare provider may perform the digital templating procedure on the medical image.

Abstract: A method of predicting the operating state of a curable bone cement composition includes determining the impedance of the bone cement composition. The impedance is used to predict a number of operating states of the bone cement composition including end-of-work time and setting time.

Abstract: A registration pointer includes a camera located in an elongated shaft having a distal end configured to be contacted to a bone of a patient to register the bone to a computer assisted orthopaedic surgery system. The camera may be a hemispherical camera and may include a panoramic camera and a wide-angle camera equipped with a fish-eye lens. The registration pointer is configured to transmit images received by the cameras to the computer assisted orthopaedic surgery system for display thereon. The computer assisted orthopaedic surgery system may be configured to generate an image, such as a hemispherical image, based on the images received from the registration pointer.

Abstract: A system and method enables data to be communicated from a position within a human body to an external data device. The system includes a wireless communication module that is electrically coupled to an implant component having a metal surface so that the implant component operates as an antenna in response to the application of a modulated carrier wave being applied to the implant component. The wireless communication module may be coupled to the implant component so that the implant component operates as a monopole or dipole antenna. When the monopole configuration is used, the system further includes a ground plane so that the electromagnetic field emitted by the implant component is reflected and the emitted and reflected fields resemble the emitted field of a dipole antenna for the carrier frequency.

Abstract: A magnetic sensor array includes a first three-dimensional magnetic sensor secured to a substrate in a central location of the substrate. A number of second three-dimensional magnetic sensors are secured to the substrate at a first distance from the first magnetic sensor. Additionally, a number of one-dimensional magnetic sensors are secured to the substrate at a second distance from the first magnetic sensor greater than the first distance. Additional magnetic sensors of any dimension may also be included. The magnetic field sensitivity of the first and second three-dimensional magnetic sensors may be less than the magnetic field sensitivity of the one-dimensional magnetic sensors. The sensing range of the first and second three-dimensional magnetic sensors may be greater than the sensing range of the one-dimensional magnetic sensors. The magnetic sensor array may also include a processing circuit coupled to the magnetic sensors.
