SUPPLEMENTARY INFORMATION:
Name of Committee: Orthopaedic and
Rehabilitation Devices Panel of the
Medical Devices Advisory Committee.
General Function of the Committee:
To provide advice and
recommendations to the Agency on
FDA’s regulatory issues.
Agenda: On June 27 and 28, 2012, the
committee will discuss current
knowledge about the safety and
effectiveness of Metal-on-Metal (MoM)
hip arthroplasty systems. FDA is
convening this committee to seek expert
scientific and clinical opinion on the
risks and benefits of these types of
devices based on available scientific
data.
Hip arthroplasty is intended to
provide increased patient mobility and
reduce pain by replacing the damaged
hip joint articulation in patients where
there is evidence of sufficient sound
bone to seat and support the
components.
There are two categories of metal-onmetal hip arthroplasty systems:
1. Metal-on-Metal total hip
replacement (THR) systems consist of a
metal ball (femoral head), a metal
femoral stem in the thighbone, and a
metal cup in the hip bone (acetabular
component). MoM THR systems are
typically indicated for use in total hip
arthroplasty in skeletally mature
patients with the following conditions:
a. Non-inflammatory degenerative
joint disease (NIDJD) such as
osteoarthritis, avascular necrosis, posttraumatic arthritis, ankylosis, protrusio
acetabuli, and painful hip dysplasia;
b. Inflammatory degenerative joint
disease such as rheumatoid arthritis;
c. Correction of functional deformity;
and,
d. Revision procedures where other
treatments or devices have failed.
2. Metal-on-Metal hip resurfacing
systems consist of a trimmed femoral
head capped with a metal covering and
a metal cup in the hip bone (acetabular
component). Hip resurfacing
arthroplasty is intended for reduction or
relief of pain and/or improved hip
function in skeletally mature patients
having the following conditions:
a. Non-inflammatory degenerative
arthritis such as osteoarthritis, traumatic
arthritis, avascular necrosis, or
dysplasia/developmental dislocation of
the hip (DDH); or
b. Inflammatory arthritis such as
rheumatoid arthritis.
Resurfacing systems are intended for
patients who, due to their relatively

younger age or increased activity level,
may not be suitable for traditional total
hip arthroplasty due to an increased
possibility of requiring ipsilateral hip
joint revision.
In February 2011, FDA published a
Web site on MoM total and resurfacing
hip systems with information for
orthopedic surgeons and for patients
with or considering hip replacement
(https://www.fda.gov/MedicalDevices/
ProductsandMedicalProcedures/
ImplantsandProsthetics/MetalonMetal
HipImplants/default.htm).
Numerous recent publications,
studies and registry reports have raised
safety concerns for MoM THRs. In
February 2012, the United Kingdom’s
(UK) Medicines and Healthcare
products Regulatory Agency (MHRA)
published a Medical Device Alert with
updated advice on the management and
monitoring of patients implanted with
MoM hip systems recommending more
aggressive followup of patients with
larger THR systems (≥36 millimeter
(mm)). Further information about
actions taken by MHRA, with links to
information about MoM hip implants
for patients and healthcare
professionals, is available on their Web
site at https://www.mhra.gov.uk/Safety
information/Generalsafetyinformation
andadvice/Product-specificinformation
andadvice/Product-specificinformation
andadvice%E2%80%93M%E2%80%
93T/Metal-on-metalhipimplants/
index.htm. (FDA has verified the Web
site address, but we are not responsible
for any subsequent changes to the Web
site after this document publishes in the
Federal Register.)
In December 2011, the American
Academy of Orthopedic Surgeons
(AAOS) published an overview on MoM
hip systems (total and resurfacing) (Ref.
1). The AAOS overview provides a
summary of clinical outcomes in
patients with MoM hip systems in
comparison to other bearing surface
combinations, addresses patient,
implant and surgical factors that may
predict successful/unsuccessful
outcomes of MoM hip systems and
discusses the prevalence of adverse
clinical problems from MoM hip
systems in comparison to other bearing
surface combinations. One item
referenced in the report is the
Australian registry, which reported
higher revision rates for patients with
implants that have large-diameter heads
(≥28 mm) (Ref. 2).
While current data are highly
suggestive that a large percentage of
patients with MoM hip systems have
successful outcomes, a recent scientific
publication raised serious concerns
about the failure rates of MoM hip

mstockstill on DSK4VPTVN1PROD with NOTICES
19294
Federal Register / Vol. 77, No. 62 / Friday, March 30, 2012 / Notices
systems for the UK population (Ref. 3).
This peer-reviewed journal article
presented the following findings
regarding primary MoM THR: (1)
Increased failure rate at 5 years for MoM
THR related to larger head sizes; (2)
significantly higher risk for revision in
female patients (Note: In the United
States, labeling discourages use of MoM
hips in females of child bearing age with
warnings in MoM THR labeling and
contraindications in MoM hip
resurfacing labeling); and (3) revisions
for dislocation in men with MoM
replacements were slightly lower,
showing some benefit to larger head
sizes.
The committee will be asked to
discuss the following as it pertains to
these devices in the U.S. population:
Device mechanisms of failure, metal ion
testing, imaging methods, local and
systemic complications, preoperative
and postoperative patient risk factors, as
well as clinical followup considerations
for patients with MoM hip systems
(total and resurfacing).
FDA intends to make background
material available to the public no later
than 2 business days before the meeting.
If FDA is unable to post the background
material on its Web site prior to the
meeting, the background material will
be made publicly available at the
location of the advisory committee
meeting, and the background material
will be posted on FDA’s Web site after
the meeting. Background material is
available at https://www.fda.gov/
AdvisoryCommittees/Calendar/
default.htm. Scroll down to the
appropriate advisory committee link.
Procedure: FDA will work with
affected industry, professional
organizations, and societies that have an
interest in the MoM hip arthroplasty
systems and who wish to make a
presentation separate from the general
open public hearing; time slots on June
28, 2012, between approximately 9 a.m.
and 10 a.m. Representatives from
industry, professional organizations and
societies interested in making formal
presentations to the committee should
notify the contact person on or before
May 1, 2012.
Interested persons may present data,
information, or views, orally or in
writing, on issues pending before the
committee. Written submissions may be
made to the contact person on or before
May 9, 2012. On June 27, 2012 oral
presentations from the public will be
scheduled between approximately 9
a.m. and 10 a.m. Those individuals
interested in making formal oral
presentations should notify the contact
person and submit a brief statement of
the general nature of the evidence or

arguments they wish to present, the
names and addresses of proposed
participants, and an indication of the
approximate time requested to make
their presentation on or before May 1,
2012. Time allotted for each
presentation may be limited. If the
number of registrants requesting to
speak is greater than can be reasonably
accommodated during the scheduled
open public hearing session, FDA may
conduct a lottery to determine the
speakers for the scheduled open public
hearing session. The contact person will
notify interested persons regarding their
request to speak by May 2, 2012.
Comments: FDA is opening a docket
to allow for public comments to be
submitted to the Agency on the issues
before the Orthopaedic and
Rehabilitation Devices Panel of the
Medical Devices Advisory Committee
beginning on March 30, 2012, and
closing on May 9, 2012. Interested
persons are encouraged to use the
docket to submit electronic or written
