20160038245 | METHOD FOR CREATING A CUSTOMIZED ARTHROPLASTY RESECTION GUIDE UTILIZING TWO-DIMENSIONAL IMAGING - Aspects of the present disclosure involve systems, methods, computer program products for customized arthroplasty cutting guides or jigs. In particular, the present disclosure provides for a method of creating a customized arthroplasty cutting jig from one or more two-dimensional (2D) images of the patient's joint. The method includes receiving the 2D images of the joint from an imaging device, reformatting the images, and creating a customized jig template from the images. One or more landmarks are electronically marked on one or more of the series of 2D images of the patient's joint through a computing device. Once the template for the cutting jig is created utilizing one or more of the electronic markers on the 2D images, a cutting or milling program is generated by the computing device that may then be provided to a milling machine to create the cutting jig corresponding to the milling program. | 02-11-2016 |
20160038159 | SPARSE CONTACT TIBIA JIG MECHANISM - A tibia cutting jig mechanism (TCJM) is provided having a number N1 of spaced apart TCJM contact points that correspond to a number N1 of spaced apart knee contact points on at least one of a tibia plateau surface and a tibia shaft surface. The TCJM contact points are positioned in contact with the tibia contact points, and a cut bar guide is positioned in contact with the TCJM to provide a location and an angular orientation of a cut bar plane that is to be used to resection and remove a selected portion of the patient's tibia. The TCJM is removed from the patient's knee, and a selected portion of the patent's tibia is resectioned and removed. The number N1 is at most about seven in some embodiments. | 02-11-2016 |
20150245922 | METHOD FOR HIP RESECTION ALIGNMENT APPROXIMATION IN HIP REPLACEMENT PROCEDURES - Aspects of the present disclosure involve systems, methods, computer program products, manufacturing processes and the like, for utilizing a series of images of a patient's anatomy to determine an estimation of relevant lengths and angles and other dimensions for use during a hip replacement procedure, which may be used to create one or more femur and/or acetabulum cavity implants or inserts useful in a partial or total hip replacement. In one particular embodiment, a jig mechanism for providing a scraper of the acetabulum cavity may be created with the information of the patient's anatomy. Further, the location of these features in the images may be determined by analyzing the gray scale value of one or more pixels around a selected point on the image. The pixel with the lowest gray scale value may then be assumed to be the edge of the cortical bone in the 2D image. | 09-03-2015 |
20150148807 | METHOD FOR FEMUR RESECTION ALIGNMENT APPROXIMATION IN HIP REPLACEMENT PROCEDURES - Aspects of the present disclosure involve systems, methods, computer program products, and the like, for utilizing a series of images of a patient's anatomy to determine a cut plane for use during a hip replacement procedure. To determine a cut plane for use during the procedure, the computer program determines a best fit line through the center of the neck of the femur, as well as a best fit line through the femoral shaft. In one particular embodiment, a cut plane through the femur may then be determined as perpendicular to the center line through the neck of the femur. Further, the location of these features in the images may be determined by analyzing the gray scale value of one or more pixels around a selected point on the image. The pixel with the lowest gray scale value may then be assumed to be the edge of the cortical bone in the 2D image. | 05-28-2015 |
20150125060 | METHOD FOR TIBIA RESECTION ALIGNMENT APPROXIMATION IN KNEE REPLACEMENT PROCEDURES - Aspects of the present disclosure involve systems, methods, computer program products, and the like, for utilizing a series of images of a patient's anatomy to determine a cut plane for use during a knee procedure. To determine a cut plane for use during a knee replacement procedure, the 2D images may be analyzed by a computer program to determine a best fit plane through one or more points along the proximal surface of the tibia and to determine one or more features of depressions within the proximal surface. With these landmarks identified in the images, a cut plane through the tibia for use during a TKA procedure may be determined. Further, the location of these features in the images may be determined by analyzing the gray scale value of one or more pixels around a selected point on the image. The pixel with the lowest gray scale value may then be assumed to be the edge of the cortical bone in the 2D image. | 05-07-2015 |
20150105698 | METHOD FOR KNEE RESECTION ALIGNMENT APPROXIMATION IN KNEE REPLACEMENT PROCEDURES - Aspects of the present disclosure involve systems, methods, computer program products, and the like, for utilizing a series of images of a patient's anatomy to determine a cut plane for use during a knee procedure. To determine a cut plane for use during a knee replacement procedure, the 2D images may be analyzed by a computer program to determine a femoral shaft axis reference line, a center of rotation of the knee, and the valley floor of the condyle notch. With these landmarks identified in the images, a cut plane through the femur for use during a TKA procedure may be determined. Further, the location of these features in the images may be determined by analyzing the gray scale value of one or more pixels around a selected point on the image. The pixel with the lowest gray scale value may then be assumed to be the edge of the cortical bone in the 2D image. | 04-16-2015 |
