Materials, clinical and morphological evaluation of custom‐made bioreactive‐glass‐coated canine hip prostheses

Bioreactive-glass-coated hip prostheses were implanted in dogs for periods of time ranging from 3 to 17 months. The prostheses were tailor-made for each animal through the use of standard radiographs. However, such a procedure does not necessarily yield a close apposition between the glass layer and bone. As a result, the initial stability of the component can be lost before bone bonding is established. Secondary to this phenomenon, the micromotion can lead to a continuous disruption of the top film on the glass despite the evidence of various reaction layers on the glass surface.
