Scientists knew for long that body
tissues’ reaction to wear products of metal-metal hip joints, compared with
reaction to wear products of polyethylene or ceramic total hips, is different.
Microscopic examination of tissues around the failed metal-metal total hips
showed that body reacts to presence of metallic wear products by strangling the
small arteries in the tissues around the metal on metal hip joints. Death of
these soft tissues follows. If the patient is allergic to metals contained in
the metal-metal total joint the death of the tissues may be extensive.

much attention among the surgeons who use metal-metal total hip models.
