STRUCTURAL CHANGES IN BONE ASSOCIATED WITH METALLIC IMPLANTS

Abstract

1. Radiological and histological observations of the tissue changes resulting from the implantation of various metals in the long bones of dogs are recorded.

2. Of the metals employed, tantalum, Vitallium, alloys "C" and "S" and F.M.B. steel were inert; silver and mild steel were reactive; F.S.T. steel occupied an intermediate position.

3. A correlation has been demonstrated between the anodic back E.M.F., the weight loss due to corrosion and the histological changes produced.
