Osteoclast

Definition - What does Osteoclast mean?

An osteoclast is one of the biggest multinuclear cells that can be found in growing bone, and is concerned with osseus tissue absorption. It is the antagonist of osteoblasts and is specifically located in the resorption pits or lacunae.

While osteoclasts play a role in bone formation and development, they can also instigate corrosion with metal implants.

Corrosionpedia explains Osteoclast

Osteoclasts are a natural part of the human body’s bones. It is vital in the growth of bone tissues, but it also responds to metal ions, which contribute to the corrosion process. This is typically the case when a person has orthopedic implants.

Polyethylene and metal are the two most common materials found in implants. They are combined to form a kind of material that is present in almost all joint implants. When made and implanted properly, these two materials rub against each other, minimizing bone wear.

Since osteoclasts react to metal ions, which increase the possibility of developing corrosion in the metal implant, various methods should be implemented to mitigate or prevent the occurrence of corrosion. The health industry is now utilizing metal alloys to obtain a good balance and the desired qualities.

Some of the common alloys used in making implants include cobalt-chromium, stainless steel as well as titanium alloys that are all corrosion resistant. Through these, replacement implants could last longer and are made stronger, benefiting the human body significantly.
