A prosthetic component suitable for long-term implantation is provided. The prosthetic component measures a parameter of the muscular-skeletal system is disclosed. The prosthetic component comprises a first structure having at least one support surface, a second structure having at least one feature configured to couple to bone, and at least one sensor. The prosthetic component is a housing for the at least one sensor and electronic circuitry. The electronic circuitry is hermetically sealed from an external environment. The at least one sensor couples to the support surface of the first structure. The support surface of the first structure is compliant. The first and second structure are coupled together housing the at least one sensor and electronic circuitry.

Prostheses are described for stabilizing dysfunctional sacroiliac (SI) joints. The prostheses are sized and configured to be press-fit into surgically created pilot SI joint openings in dysfunctional SI joint structures. The prostheses have an integral structure with opposed elongated sections connected by a bridge section. The elongated sections, in some instances, have an unequal length.

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.

Aspects of the present disclosure involve a method of diagnosing and treating a sacroiliac joint of a patient comprising: a) delivering a first member into the ilium via a first posterior approach; b) delivering a second member into the sacrum via a second posterior approach; and c) diagnosing an ailment of the sacroiliac joint by: manipulating the first member relative to the second member; or identifying joint movement via a sensor positioned in or near the sacroiliac joint.

Concepts for measuring and monitoring characteristics of osseous tissue are presented. In various embodiments, a monitoring probe may be inserted through a hollow passageway within a cannulated screw during an operation in order to measure characteristics of the osseous tissue in which the cannulated screw is inserted. In various embodiments, the cannulated screw may be inserted into a femoral head, through a physis, and into an epiphysis for stabilization of Slipped Capital Femoral Epiphysis. During surgical treatment thereof, a pressure transducer may be inserted into the osseous tissue through the cannulated screw in order to monitor epiphysis perfusion through the femoral head.

A method of a measuring kinematic parameter in a subject is provided. The method includes obtaining a first magnetic resonance (MR) image set of a bone marrow segment of the subject in a first position and obtaining a second MR image set of the bone marrow segment of the subject in a second position where the second position different from the first position. The method further includes registering the first image set with the second image set and measuring a kinematic parameter.

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.

A sensing system for tracking a center of rotation of a joint can include a computer system including processing circuitry configured to perform operations including: retrieve a first data set collected by a sensor device configured to be implanted into a patient in a fixed location on or within a first bone of the joint, the sensor device configured to collect data associated with movement of the first bone of the joint at a first time, retrieve a second data set collected by the sensor device at a second time subsequent to the first time; analyze the first and the second data sets to calculate first and second center of rotation locations; and compare the first and second center of rotation locations to track migration in the center of rotation of the joint over time.

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.

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.
