The rotation mechanism is configured to rotate the medial and lateral posterior feet of the sizer body relative to the tensor frame toward a lateral side of the patient's knee.

Abstract: Systems and methods for femoral medial condyle spherical center identification and tracking are described herein. Once the spherical center of the medial condyle is identified, the spherical center is tracked using a pin or internal reference. The spherical center may be used to provide a key kinematic motion reference, such as when the medial condyle is adjusted during a surgical procedure. The tracking may be used to provide optical tracking, inertial tracking, or other tracking. In contrast with surface-mounted optical trackers, the spherical center tracking is not lost during resection (e.g., removal) of a bone surface. Tracking the medial condyle spherical center may reduce or eliminate the need for a surface-mounted optical tracker or preoperative 3-D modeling or of the joint.

Abstract: A method of pre-operatively developing a reverse shoulder arthroplasty plan can include receiving an image of a patient shoulder comprising a humerus and a glenoid. The image can be segmented to develop a 3D shoulder model. Virtual surgery can be performed on the 3D shoulder model to generate a modified shoulder model. The virtual surgery can include resecting and reaming a virtual humerus of the 3D shoulder model, and reaming a virtual glenoid of the 3D shoulder model. Selection of a humeral implant and selection of a glenoid implant can be received. A virtual representation of the humeral implant can be implanted on the virtual humerus and a virtual representation of the glenoid implant on the virtual glenoid to virtually update the modified shoulder model. A range of motion of the patient shoulder can be determined and a reverse shoulder arthroplasty can be finalized based on the range of motion.
