2. The August 2010 DePuy hip replacement
recall for some 93,000 defective implants
worldwide might have been bad news
after data confirmed that the device design
has had an unreasonably high rate of
failure. Yet there is good news for the
future of metal-on-metal implants.
Researchers from US and Germany have
discovered a stratum of “graphitic carbon”
on the head part of all-metal hip implants,
new research presents. The U.K.
Medicines and Healthcare Products
Regulatory Agency (MHRA) released a
DePuy and Stryker hip replacement
warning on information of high failure
rates, in April 2012.
Design problems with metal-on-metal hip
implants may have caused the metal
components of the DePuy device to rub
against each other and shed microscopic
metal particles into the body.

3. Below is the list of metal poisoning symptoms:
• Gastrointestinal problems
• Haemorrhages
• Optic nerve / vision problems
• Deafness
• Neuropathy
• Kidney failure
• Thyroid problems
• Cardiomyopathy
• Hip dislocation and unexplained hip pain
• Swelling
• Complete hip failure
• Pseudotumors
• Tissue damages
• Additional hip replacement or revision surgery
• Loosening of hip device

4. • Detachment of the hip device from the bone
• Genotoxicity (genetic damage)
• Bone fractures
• Bone loss
• Inflammatory reactions
• Presence of chromium and cobalt in the blood that may lead
to cancer
“Most major medical centers have seen issues with this device,”
based on the newspaper interview with the chairman of orthopedic
surgery at Rush University Medical Center in Chicago, Dr. Joshua J.
Jacobs. “This does not come as a surprise.”

5. “Graphite has been used as a lubricant for over a century. It is a classic
lubricant, and it appears to form naturally,” according to Laurence Marks, one of
the researchers and also a professor at Northwestern University, teaching
materials science and engineering.
Furthermore, for the prevention of metal poisoning and corrosion, he suggests
that makers of metal-on-metal hip implants could consider about the graphite
formation on the devices. The benefits of graphite compound was discovered in
a recent study funded by the National Institutes of Health that was published in
the medical journal, Science.
“Now that we have a handle on how they are working and why they were
working well, we can start to design them to make them better,” says Marks.

6. Beginning in 2008, the Food and Drug Administration
(FDA) had received nearly 400 reports of patients who
encountered problems with DePuy hip device. To date, a
number of patients have filed court charges against DePuy
Orthopaedics Inc. and its mother company, Johnson &
Johnson.These cases allege that the company delayed the
issuance of DePuy hip replacement recall even though it
knew about the problems of the products. DePuy should
circulate a wide range of information regarding
malfunctioning hip replacement symptoms so that its
patrons would be provided with due medical attention. Visit
