If you or a loved one have suffered as a result of metal-on-metal hip implants, you may be able to make a medical negligence compensation claim.


1. What are hip implants?

Hip implants are prosthetic devices fitted to replace joints that have suffered damage or deterioration. Also known as hip replacements, this surgery is considered a major procedure, and will only be considered if other treatments, such as physiotherapy, aren’t successful in reducing pain or improving mobility.

2. How is a hip replacement procedure performed?

During a hip replacement procedure, a surgeon removes the damaged or diseased ball and socket of a hip joint and replaces it with a man-made metal, plastic or ceramic hip joint. The surgery is normally carried out under general anaesthetic.

3. What are hip implants made of?

Hip implants can be made of a number of materials, including: 

  • Metal-on-plastic: A metal ball attached to a plastic socket. This is the most commonly-used type of hip implant.
  • Ceramic: Including ceramic-on-plastic (ceramic ball attached to a plastic socket) and ceramic-on-ceramic (where both components are ceramic), which is often used on younger and more mobile patients.
  • Metal-on-metal (MOM): As the name suggests, both components are made of metal. This was developed in the 1990s as an alternative to metal-on-plastic, but has led to concerns about potential toxicity and muscular damage. 

4. What medical conditions could cause the need for a hip implant?

You may be offered a hip replacement if you are in severe pain, and/or suffering from swelling and stiffness that makes going about your day-to-day life difficult.

Medical conditions known to lead to hip replacements include:

  • Osteoarthritis
  • Rheumatoid arthritis
  • Septic arthritis
  • Ankylosing spondylitis
  • Bone dysplasia
  • Hip fractures 

5. Are hip implants safe?

The majority of hip implants perform as expected and don’t cause problems for patients; however the NHS states that metal-on-metal or MOM hip implants can wear down quicker than those made out of alternative materials, potentially causing damage and inflammation to the bone and tissue surrounding the hip.

There are also concerns that metal-on-metal hip implants could leak traces of metal into a person’s bloodstream. Whilst there is no definitive link between the metal in MOM implants and illness, there have been a small number of cases where high levels of metal in the bloodstream can cause effects to the heart, nervous system and thyroid gland.

6. How long do hip implants last?

Hip implants, including metal-on-metal hip implants, usually last 10 to 12 years. However, the concerns are that some MOM implants degenerate far sooner, leaving people in need of more regular check-ups and surgical operations to fix damage they have caused.

7. Are metal-on-metal hip implants still being used?

No. MOM implants were largely phased out after a 2013 study found the implant had an unacceptably high failure rate in 17,000 patients studied.

8. How do I tell if my metal-on-metal hip implant is defective?

Your MOM hip implant could be defective if you are suffering with any of the following symptoms:

  • Groin, hip or leg pain
  • Swelling near the hip
  • A noticeable grinding or clunking noise coming from the joint
  • Issues with mobility 

General changes to your health such as fatigue, vision or hearing issues, chest pains, numbness or weakness, weight gain or feeling cold could also be indicators of a faulty hip implant.

Some people can also be asymptomatic (not displaying any symptoms), meaning that the implants could be unknowingly causing bodily damage. Thompsons Solicitors recommends that you contact your GP immediately for a check-up if you have received a metal-on-metal hip implant, to make sure that there isn’t an underlying problem. 

9. My metal-on-metal hip implant is causing me discomfort – what should I do?

If you or a family member are suffering pain, or have fears that your metal-on-metal implant could be damaging your health or is causing you pain, you should visit your GP immediately. They will be able to investigate whether your MOM implant is the cause of the pain and will discuss the available steps to prevent it causing further damage.

Recently issued MHRA guidance states that men who are suffering with symptoms as a result of their MOM implant will need to have an annual check-up, while those who are asymptomatic will need to visit their GP for tests every three years. All women who have had the implant will need annual tests, as research has found that women are more likely to need replacement surgery.

10. My GP has diagnosed my metal-on-metal implant as the cause of my discomfort – can I make a medical negligence claim?

Yes.

12. How long do I have to make a MOM implant medical negligence compensation claim?

Because MOM implants are only meant to last 10 to 12 years, you cannot usually make a personal injury claim if the implant was manufactured over 10 years ago. There may be exceptions, however, so it is always best to speak with Thompsons Solicitors first to see if you would be eligible to make a metal-on-metal hip implant claim.

13. Are there time limits on making a metal-on-metal implant compensation claim?

Yes, all clinical negligence and medical accident claims have a time limit. You must begin your claim within three years of the date when you could have reasonably known you had an injury – for example a doctor’s diagnosis.

There are very few exceptions to this, so make sure you get in touch with our medical negligence experts as soon as possible to discuss making a metal-on-metal hip implant claim.

14. How can I pay for a medical negligence compensation claim?

Thompsons Solicitors is always transparent with legal fees and we will always help you choose the best payment option. One way to fund a personal injury compensation claim is via a ‘no win, no fee’ agreement, also known as a conditional fee agreement. As the name suggests, you won’t pay a penny if your claim is unsuccessful, but if your claim succeeds, a success fee of no more than 25 per cent will be taken from the overall compensation secured. You can learn more by speaking to a member of our legal team or visiting our Fees and Payment page

If you or a family member are part of a trade union, your membership entitles you to a free initial consultation and specialist terms after that.

However you choose to fund your claim, we will make sure that you don’t face financial risk.
