Scintigraphy used to compare cemented and cementless prostheses: two-year follow-up

Cemented and cementless total hip prostheses were followed up after two years, using computerized skeletal scintigraphy. The authors discuss the protocol used for the study, and compare the validity of this method with that of traditional radiography in monitoring the long-term results. They evaluated the degree of reorientation in the host bone and showed that there were significant differences between the two types of prosthesis.
