Abstract: A handling tool for coupling to a cutting guide includes a substantially elongate first end shaped to be grasped by human hand. The tool includes at least two mating tines, disposed at a second end of the tool. The mating tines are biased to move toward each other and are forced apart from each other by a cam portioned therebetween. The mating tines each include a mating means for mating the tool with the cutting guide.

Abstract: A bipolar endoprosthesis assembly which provides for a wide-range of motion between a bone and a socket (e.g., a femur and an acetabular socket), comprising a metal outer shell element, a ultra-high molecular weight, low-friction insert formed to fit within the shell element, and a locking ring designed to lock the assembly together with a femoral head prosthesis. The outer shell has a generally spherical shape on its outer surface to be received by a human socket such as the acetabulum. The inner surface of the outer shell is faceted to inhibit rotation of a correspondingly shaped inner insert. The insert has an outside surface shaped to mate with the inside surface of the outer shell element. The locking ring is slotted to facilitate insertion of a femoral head prosthesis. The locking ring also has dual sets of locking barbs shaped to mate with recesses on the inner surface of the outer shell element. The redundant locking mechanism of the locking ring inhibits accidental in vivo disassembly of the device yet allows for relatively easy intraoperative disassembly without specialty tools or fixtures.

Abstract: A system and method may be used to evaluate soft tissue. A hip joint evaluation may use an adjustable spacer, such as varying sized physical spacers or an inflatable bladder, along with a sensor to measure force, pressure, gap distance, or the like, for example during a range of motion test. A method may include using a maximum pressure during the range of motion test to determine a maximum pressure during the range of motion test. The maximum pressure may be output for display on a user interface.

Abstract: A surgery-facilitating system and method include a controller, a first tracker positioned on a first member of a joint, and a second tracker positioned on a second member of the joint. A first anatomical entity of the first member and a second anatomical entity of the second member are tracked using the first and second trackers to generate in the coordinate system, pre-operative kinematic data of the joint during a first movement of the joint, intra-operative kinematic data of the joint during a second movement of the joint, and post-operative kinematic data of the joint during a third movement of the joint. A surgical plan is generated for the surgical procedure of the subject based at least in part on the pre-operative kinematic data, the intra-operative kinematic data, or both, of the joint in the coordinate system.

Abstract: A selection system comprises a ring, a plurality of shims, a measurement device, and at least one glenoid component. The ring is configured to couple to a humerus. A shim of the plurality of shims is configured to couple to the ring. The measurement device is configured to couple to the shim. Each shim of the plurality of shims has a different height when coupled to the ring. The selection system generates measurement data to support the selection of at least one prosthetic component for a shoulder joint in a surgical environment. The shoulder joint geometry can be adjusted by changing shims, changing glenoid component or both. The selection system is removed after the selection of the final prosthetic components for the shoulder joint. The final prosthetic components are installed in the shoulder joint. The measurement device is placed in the shoulder joint and measurement data is generated to verify performance.

Abstract: A method includes receiving by a controller, a surgeon-specific surgery profile for an implantation of an implant into a joint, implant profiles, a patient-specific post-surgery desired functional profile of the joint after the implantation, and bone registration data for a first bone member and a second bone member of a patient are inputted into a surgical plan model to generate a surgical plan. The surgical plan model is designed to achieve the patient-specific post-surgery desired functional profile based at least in part on a plurality of dependencies between a plurality of surgical parameters, the implant profiles, at least one functional parameter representative of the expected functional performance of the joint, and movement-related data of the joint. The surgical plan is outputted on a graphical user interface (GUI) on a surgery assistant device to facilitate the implantation.
