Publication number: 20220387186Abstract: A surgical sensor system for collecting internal patient data comprises a sensor module comprising a housing and a sensor disposed within the housing, and an attachment device comprising a socket for receiving the housing and an exterior anchor feature for attaching the attachment device to biological matter. A method of implanting a sensor module for use with an orthopedic implant device comprises making an insertion portal in anatomy of a patient, positioning a sensor module in the anatomy in a first position relative to the insertion portal, and positioning an orthopedic implant in the anatomy in a second position relative to the insertion portal such that the orthopedic implant is separate from the sensor module.Type: ApplicationFiled: June 3, 2022Publication date: December 8, 2022Inventors: Nathan Golemon, JR., John Kyle Mueller, Jeffrey E. Bischoff, Matthew Vanderpool, Louis-Philippe Amiot, Annelise Galloway, Pierre Couture, Ted Spooner

Patent number: 11490965Abstract: The subject matter includes systems, methods, and prosthetic devices for joint reconstruction surgery. A computer-assisted intraoperating planning method can include accessing a first medical image providing a first view of a joint within a surgical site as well as receiving selection of a first component of a modular prosthetic device implanted in the first bone of the joint. The method continues by displaying a graphical representation of the first component of the modular prosthetic device overlaid on the first medical image, and updating a graphical representation of the first component based on receiving positioning inputs representative of an implant location of the first component relative to landmarks on the first bone visible within the first medical image. The method concludes by presenting a selection interface enabling visualization of additional components of the modular prosthetic device virtually connected to the first component and overlaid on the first medical image.Type: GrantFiled: October 22, 2020Date of Patent: November 8, 2022Assignee: Zimmer, Inc.Inventors: Jeffrey E. Bischoff, Joanna Hucky

Publication number: 20220304595Abstract: 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.Type: ApplicationFiled: March 17, 2022Publication date: September 29, 2022Inventors: Clinton E. Kehres, Jeffrey E. Bischoff

Patent number: 11324598Abstract: Methods are disclosed for designing a tibial implant to minimize cortical impingement of a keel or other fixation structure when the tibial implant is implanted in the tibia bone. The design of the keel or other fixation structure on the tibial baseplate can be based on determining a common area between defined cancellous regions of at least two tibia bones. Methods are disclosed for designing a femoral component having a stem extension such that the stem can be sufficiently placed in the diaphysis of the femur when the femoral component is implanted. The method includes determining a canal axis in a femur that creates adequate engagement between a reamer and the diaphysis of the femur.Type: GrantFiled: January 15, 2020Date of Patent: May 10, 2022Assignee: Zimmer, Inc.Inventors: Yifei Dai, Christine Schaerer, Dwight T. Todd, Jeffrey E. Bischoff, Adam D. Henderson

Publication number: 20220096243Abstract: An orthopaedic tibial prosthesis includes a tibial baseplate with an asymmetric periphery which promotes proper positioning and orientation on a resected tibia, while also facilitating enhanced kinematics, soft-tissue interaction, and long-term fixation of the complete knee prosthesis. The asymmetric baseplate periphery is sized and shaped to substantially match portions of the periphery of a typical resected proximal tibial surface, such that proper location and orientation is evident by resting the baseplate on the tibia. The baseplate periphery provides strategically positioned relief and/or clearance between the baseplate periphery and bone periphery, such as in the posterior-medial portion to prevent deep-flexion component impingement, and in the anterior-lateral portion to avoid undue interaction between the anatomic iliotibial band and prosthesis components.Type: ApplicationFiled: December 8, 2021Publication date: March 31, 2022Inventors: Mary S.S. Wentorf, Jeffrey E. Bischoff, Raymond C. Parisi, Katherine M. Rettig

Publication number: 20210330389Abstract: 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.Type: ApplicationFiled: July 9, 2021Publication date: October 28, 2021Inventors: Ravikumar Varadarajan, Jeffrey E. Bischoff, Clinton E. Kehres, Bryce A. Isch
