ABSTRACT

This paper describes the biological characteristics of the metal tantalum (Ts) and the application status of tantalum in artificial joints, bone necrosis, spine, defects of bone and other aspects of bone. The early clinical application results of tantalum in bone diseases were satisfactory, but it is necessary to do further study of tantalum in a deep going way, and further detailed comparison between the tantalum with other metals as orthopedics implants. The advantage of tantalum materials as orthopedic implants still needs to be verified by a great deal of clinical cases for a long period of time.
