The rising number of cases filed by patients against hip implants
manufacturer have piqued the interest of many orthopedic experts,
medical industry observers say. Metal-on-Metal hip devices have unique
risks which may expose patients to a variety of health problems,
according to the Food and Drug Administration (FDA). There are several
recommendations given by the FDA to help patients and health care
providers manage MoM hip implant problems. Patients need to coordinate
with their surgeons to ensure that they report the symptoms that they
encounter. There are many cases filed by patients who have experienced
some of these complications but the Biomet manufacturer motions to dismiss these cases.
Patients who experience the following symptoms may need to report it to their health care providers immediately:
- Hip or groin pain
- Difficulty in walking or limping
- Numbness
- Redness and swelling
- Signs of worsening symptoms
These
symptoms may indicate that the patient is already experiencing severe
complications of the metal ions released by the metal hip implant.
However, some have experienced other health problems that may be away
from the hip implant. The worsening symptoms that may be related to the
kidney, heart, skin, thyroid gland or nervous system may need to have a
re-diagnosis. Although these problems are far from the hip, they may
still be related to the metal particles from the implant. These are
hypersensitivity reactions from the metal ions.
These
hypersensitivity reactions are still highly unpredictable as there are
limited data on their pattern and effect. Men and women may react
differently to various amounts of metal ions in their blood. Some may
develop symptoms after being exposed to small amounts of metal particles
while some may build-up tolerance and will only develop symptoms after
reaching critical levels. This varying degree of sensitivity also
contributes to the difficulty in predicting the patients that may be
develop hypersensitivity reactions. However, there are some risk factors
that may lead to the development of these health problems.
The
following patients who have these risk factors are advised to have
frequent follow-up with their health care providers, as recommended by
the FDA:
- Female
- Have bilateral implants
- Kidney problems
- Have high levels of physical activity
- Severely overweight or obese
- Problems with the immune system
- Metal hip implants not placed correctly
- Taking high doses of corticosteroids
- Has resurfaced hip implants with small femoral heads
Individuals
with MoM hip devices who have developed severe complications believe
that their implant may have been the cause of their problems. Some of
them asked a Biomet hip lawyer to help them file their case.
