Patent number: 11478568Abstract: A target tissue can be treated with a radioisotope. Some methods for treating a target tissue with a radioisotope include determining a distance between a target tissue and a surface of a matrix material to be positioned adjacent the target tissue and, based on the determined distance, determining an activity to be mixed with the matrix material to obtain a desired activity concentration. Some methods further include mixing the radioisotope with the matrix material. In some embodiments, the matrix material comprises bone cement, and the target tissue is a tumor in a bone. The radioisotope may be a beta-emitting radioisotope mixed in the cement at a concentration to form a radioactive cement.Type: GrantFiled: March 19, 2019Date of Patent: October 25, 2022Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Joyce H. Keyak, Tadashi Kaneko, Harry B. Skinner, Varun Sehgal

Patent number: 9245069Abstract: Methods are provided for modeling structural behavior of a bone. For example, the methods can model the structural behavior of a femur, and in particular, a proximal femur, under conditions representing a fall onto the greater trochanter of the proximal femur. In such an embodiment, the method can comprise determining a strength of the femur, by a processor and based on (a) the elastic modulus, (b) the cortical bone yield strength, (c) the stress level ?min, and (d) the post-yield stress-strain slope of the proximal femur.Type: GrantFiled: February 4, 2013Date of Patent: January 26, 2016Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventor: Joyce H.
