Publication number: 20240050155Abstract: A method for planning an arthroplasty procedure on a patient bone. The method may include accessing generic bone data stored in a memory of a computer, using the computer to generate modified bone data by modifying the generic bone data according to medical imaging data of the patient bone, using the computer to derive a location of non-bone tissue data relative to the modified bone data, and superimposing implant data and the modified bone data in defining a resection of an arthroplasty target region of the patient bone.Type: ApplicationFiled: October 13, 2023Publication date: February 15, 2024Applicant: HOWMEDICA OSTEONICS CORPORATIONInventors: Elena I. Pavlovskaia, Oleg Mishin, Boris E. Shpungin, Ilwhan Park, Venkata Surya Sarva, Irene Min Choi

Patent number: 10993744Abstract: A method of planning an arthroplasty procedure on a femur and tibia of a patient. The method includes receiving a first two-dimensional image of the femur and the tibia, and identifying, in the first two-dimensional image, a proximal femur feature, a distal tibia feature, and a bone contour. The method further includes running a transformation process to align a bone model representative of the femur and the tibia into a coordinate system with the first two-dimensional image, the bone model having a bone model contour that is aligned with the bone contour of the femur and the tibia in the first two-dimensional image. And the method further includes applying an implant model to the bone model in order to determine coordinate locations for the arthroplasty resection.Type: GrantFiled: September 11, 2020Date of Patent: May 4, 2021Assignee: Howmedica Osteonics CorporationInventors: Ilwhan Park, Keun Song, Oleg Mishin, Michael Santarella, Elena I. Pavlovskaia, Boris E. Shpungin

Patent number: 10912571Abstract: A smooth mating surface model defining a mating surface of a customized arthroplasty jig is generated. For example, sagittal slices of a volumetric image of a patient bone are segmented with segmentation splines. An anatomically accurate model of the patient bone is generated from the segmentation splines. The anatomically accurate model includes anatomically accurate segmentation splines. The anatomically accurate segmentation splines are transformed into mating surface contours. Any inadequate segments of the mating surface contours are modified to obtain modified mating surface contours. A mating surface model of the patient bone is generated based on the mating surface contours and the modified mating surface contours. Three-dimensional cross-sections of the mating surface model are smoothed to generate the smooth mating surface model.Type: GrantFiled: March 17, 2014Date of Patent: February 9, 2021Assignee: Howmedica Osteonics CorporationInventors: Elena I. Pavlovskaia, Boris E. Shpungin, Oleg Mishin, Olga Sominskaya

Publication number: 20160022370Abstract: Implementations described and claimed herein provide systems and methods for generating a smooth mating surface model defining a mating surface of a customized arthroplasty jig. In one implementation, sagittal slices of a volumetric image of a patient bone are segmented with segmentation splines. An anatomically accurate model of the patient bone is generated from the segmentation splines. The anatomically accurate model includes anatomically accurate segmentation splines. The anatomically accurate segmentation splines are transformed into mating surface contours. Any inadequate segments of the mating surface contours are modified to obtain modified mating surface contours.
