The present invention features a sensor implant that can adhere to bone. The sensing device is capable of sensing bone strains and reporting them as well as loads passing through bone for extended periods of time. The sensor implant can also be used to monitor bone growth for bone segmental repair of long bones or to monitor changes in bone characteristics of patients with osteoporosis. The present technology has the potential to give physicians the ability to predict when a patient with osteoporosis has an impending fracture and thus be able to intervene and prevent further damage.

Disclosed herein are systems and methods for providing peripheral services for an implant with sensors. A method according to the present disclosure may creating a patient account on a patient monitoring platform, determining sensor information to be measured from one or more sensors disposed on an implant coupled to a patient using the patient account, determining a duration during which sensor information is collected and transferred from the one or more sensors to the patient monitoring platform, analyzing sensor information received from the one or more sensors on the patient account via an external device, and communicating corrective steps from the external device to the patient or the implant via the patient account.

Disclosed herein are joint implants and methods for tracking joint implant performance. A joint implant according to the present disclosure can include a first implant coupled to a first bone of a joint; a second implant coupled to a second bone of the joint; an insert coupled to the first and second implants; an acoustic exciter configured to emit a vibration signal; a sensor to measure the vibration signal of the first implant, the second implant, and the insert; and a processor operatively coupled to the sensor, the processor configured to output a vibration signature to an external source.

Systems and methods for estimating anatomic alignment between two or more bones are described herein. An example method can include registering an anatomic reference frame. Additionally, the method can include establishing a respective rotational relationship between each of one or more bones and an orientation sensor attached to each of the one or more bones. The method can also include receiving, from each of the orientation sensors, orientation information, and then calculating an orientation of a bone relative to the anatomic reference frame. The method can further include calculating, using the respective orientations of the bones relative to the anatomic reference frame, an anatomic alignment parameter between first and second bones.

Disclosed herein are joint implants and methods for tracking joint implant performance. Braces and trackers for assessing pre- or post-surgical kinematic movement of a joint are also disclosed. The implants, braces and trackers can be utilized together or separately. Trackers having magnets can be implanted in select areas of the joint and sensors included in the braces can cooperate with the trackers to provide joint movement information to both the patient and the surgeon. Braces that do not require cooperation with implanted trackers are also disclosed, as are their uses.

Disclosed herein are methods for determining kinematic information of a joint. A method according to one embodiment may comprise the steps of receiving data obtained from a sensor of an implanted joint implant, analyzing the data with a trained estimation model to simultaneously determine kinematic information of the joint in six degrees of freedom, and outputting the kinematic information. In another embodiment, a method may comprise the steps of applying data obtained from a Hall sensor of an implanted joint implant to a trained estimation model to simultaneously determine kinematic information of the joint in six degrees of freedom; and outputting the kinematic information.

Component (1) for endosseous screw, provided with a main body (10) which supports electronics (2) comprising at least one signal emission circuit and at least one sensor for acquiring one or more biophysical parameters of a patient, said component (1) being associable with an endosseous screw.

A device for the non-invasive sensing of the length of an implantable medical device includes animplantable medical device having first and second portions moveable relative to one another and a layer of resistive material disposed on one of the first and second portions. A contact is disposed on the other of the first and second portions, the contact being in sliding contact with the layer of resistive material upon relative movement between the first and second portions. A circuit is configured to measure the electrical resistance along a path including a variable length region of the layer of resistive material and the contact. The electrical resistance can then be converted into a length.

This disclosure relates to a method of using an adjustable tibial sizer for use in knee arthroplasty. The sizer includes a two-part body comprising: a first body portion, a second body portion, and a connection element extending therebetween.

Disclosed herein are joint implants and methods for tracking joint implant performance. A shoulder implant according to the present disclosure can include a glenoid implant on a first bone and a humeral implant on a second bone of a shoulder. The glenoid implant can include magnetic markers. The humeral implant can include marker readers to provide positional data of the glenoid implant with respect to the humeral implant. The humeral implant can include at least one sensor to measure kinematic data between the glenoid and humeral implants. A processor can be coupled the marker reader and the at least one sensor. The processor can be configured to output the positional data and the kinematic data to an external source.
