The present invention relates generally to the field of orthopedics, and more particularly to a pelvic referencing guide and methods of using the guide in orthopaedic surgery, specifically total hip arthroplasty.

A medical implant includes a sensor that detects electromagnetic waves; and a data transmission unit that can wirelessly transmit data supplied by the sensor to a receiving unit.

A method of determining axial alignment of a lower limb includes determining a three-dimensional volume based on a scan of a lower limb of a patient, identifying a level of hip version by referring to a first axis of symmetry of a femoral neck and a second axis of symmetry of a distal portion of a femur, wherein hip version is defined by an angle between the first axis of symmetry and the second the second axis of symmetry, identifying a level of tibial torsion by referring to a third axis of symmetry of a proximal portion of a tibia and a fourth axis of symmetry of a distal portion of the tibia, wherein tibial torsion is defined by an angle between the third axis of symmetry and the fourth axis of symmetry, and providing the level of hip version and the level of tibial torsion to a user.

A system is disclosed herein for providing a kinetic assessment and preparation of a prosthetic joint comprising one or more prosthetic components. The system comprises a prosthetic component including sensors and circuitry configured to measure load, position of load on a curved surface, joint stability, range of motion, and impingement. In one embodiment, the system is for a ball and socket joint of a musculoskeletal system. The system further includes a computer having a display configured to graphical display quantitative measurement data to support rapid assimilation of the information. The kinetic assessment measures joint alignment under loading that will be similar to that of a final joint installation. The kinetic assessment can use trial or permanent prosthetic components. Furthermore, adjustments can be made to the applied load magnitude, position of load, and joint alignment by various means to fine-tune an installation.

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.

Systems, methods and a sensor alignment mechanism are disclosed for medical navigational guidance systems. In one example, a system to make sterile a non-sterile optical sensor for use in navigational guidance during surgery includes a sterile drape having an optically transparent window to drape the optical sensor in a sterile barrier and a sensor alignment mechanism. The alignment mechanism secures the sensor through the drape in alignment with the window without breaching the sterile barrier and facilitates adjustment of the orientation of the optical sensor. The optical sensor may be aligned to view a surgical site when the alignment mechanism, assembled with the sterile drape and optical sensor, is attached to a bone. The alignment mechanism may be a lockable ball joint and facilitate orientation of the sensor in at least two degrees of freedom. A quick connect mechanism may couple the alignment mechanism to the bone.

A method of generating a measurement of anatomy of interest from two-dimensional imaging includes receiving two-dimensional imaging associated with anatomy of interest; detecting a plurality of anatomical features of the anatomy of interest in the two-dimensional imaging using at least one machine learning model; determining characteristics of the plurality of anatomical features based on the detection of the plurality of anatomical features; and generating at least one measurement of the anatomy of interest based on at least some of the characteristics of the plurality of anatomical features.

A data processing method performed by a computer for judging implant orientation data representing an orientation of a first implant part relative to a first bone, the first implant part being part of an implant pair which further comprises a second implant part for a second bone, the implant pair being envisaged to be implanted in a patient, comprising the steps of: —acquiring the implant orientation data, -acquiring second implant orientation data representing the orientation of the second implant part relative to the second bone, -acquiring implant shape data representing the shapes of the first and second implant parts, —acquiring activity data representing at least one desired activity of the patient to be possible after implanting the implant, wherein each desired activity has an associated range of motion between the first bone and the second bone, —calculating a range of motion volume, which represents possible orientations between the first bone and the second bone over three rotational axes, from the implant orientation data, the second implant orientation data and the implant shape data, and —judging the implant orientation data to be feasible if the ranges of motion of all desired activities lie within the range of motion volume.
