Blind and deaf after total hip replacement?

Only recently was the problem widely brought to the attention of orthopaedic surgeons. After revision of a ruptured ceramic head by the substitution of the broken head with a metal one, fine ceramic particles do remain in situ and in a short time can destroy all kinds of metal, by acting like a grinding wheel.

Therefore, the finding of endogenous cobalt-chromium poisoning is not surprising, owing to a high metal ion concentration. A new ceramic–ceramic hip would have been a better and safer solution. If the trunion is damaged, conversion to ceramic on ceramic is still possible thanks to special heads and adaptors. If the trunion is too seriously damaged the stem must be changed.
