Alternatively, an initial surgery may be performed to remove previous prosthetic material, and the new prosthesis is then inserted in a separate surgery at a later time. In such cases, especially when complicated by infection, a spacer may be used, which is a sturdy mass to provide some basic joint stability and mobility until a more permanent ...
