Part One: Fascinating article published in Jan 2010 in the Journal of Bone and Joint Surgery on the problems associated with failure of MoM hip replacements.

( From the Journal of Bone and Joint Surgery [Br] 2010;92-B:38-46)

I will present my overview of this in two parts.  Following is Part One.

I found this study to be a good encapsulation of the problems surrounding MoM hips dating from 1975 in the bibliography. The bibliography noted the following 35 articles from the medical literature re issues surrounding MoM implants:

·         18 articles dealing with Cobalt Toxicity, abnormal blood metal levels and hypersensitivity with MoM implants.
o   7 of these were pre 2000!.... 10 years ago!
§  1 in 1975
§  1 in the 80’s
§  5 in the 90’s
·         7 articles dealing with hip positioning
o   1 article predated 2000
·         3 articles dealing with soft tissue damage
o   None predated 2000
·         2 articles dealing with the appropriate age and sex targets for the MoM implants
o   None predated 2000
·         2 articles dealing with wear rates
o   None predated 2000
·         2 evaluations
o   Both predated year 2000
·         1 causes and prevention
o   Written in 1990

This is one recent article with what would appear to be a reasonable bibliography on the hip problems.  It would appear that issues surrounding the MoM implants were all surfaced on numerous occasions over the years.

Stay tuned for part two.
