Abstract: 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.

Abstract: A surgical device is disclosed which provides a safe means of passing a cerclage wire around a bone and the technique for accomplishing this task is described. This device uses the tactile sensation of the human hand to achieve appropriate placement of the cerclage wire. Thus, Irregularities in the bone fragments of a fracture or bone graft augmenting a fracture can safely be encircled and secured. The device permits retrograde placement of the cerclage wire compatible with available manufactured devices.
