Abstract
Routine metallurgical examination of surgical implants removed from patients in 1970 revealed that four osteotomy plates had suffered extraordinary amounts of corrosion. A typical metallurgical examination for one of the plates is reported. Standard tests showed that the corrosion was a result of “sensitization,” a well-known problem with stainless steels.
The results of this investigation indicate that the manufacture of stainless steel implants should be more rigidly controlled.
