Do you sometimes feel a strange tightness or pain in your hip? Is it difficult to walk, bend your hip, or get up from a sitting position? You may think that this is just a sprain, or something that happens as you get older. But this is a condition that we are going to talk about today, which is called Hip Impingement . Let's learn more about this, because this is a problem that many people can have.
What is Hip Impingement?
Simply put, this condition occurs when the bones in your hip joint don't fit together properly, rubbing against each other, and getting stuck. Think of it this way: your hip joint is a ball-shaped part of your thigh bone (femur, the long bone in your upper leg) that fits into a cup-shaped socket (acetabulum, the bony socket in your hip socket). When this ball and socket fit together properly, we can easily bend, extend, and rotate our hips.
So, this is what doctors call `Femoroacetabular Impingement` or `FAI` for short. `Femoroacetabular` means the area where the thigh bone (`femur`) and the hip socket (`acetabulum`) meet. `Impingement` is the medical term for something getting stuck, rubbing, or rubbing against each other inside a joint. So `FAI` or `Hip Impingement Syndrome` is something like that.
This can be very painful . It can also make it difficult to walk or move your hip. You may feel a constant tightness or pain on one side. It feels like something is stuck inside. Over time, this tightness can damage the cartilage that protects your hip joint, the cushion-like part that keeps two bones from rubbing against each other.
If you have hip pain, stiffness, or other symptoms that don't improve after a week or two, definitely see a doctor . The sooner you recognize it, the easier it is to treat.
What are the symptoms of this?
The main symptoms of `Hip Impingement` are:
- Hip pain: This is the most commonly seen symptom.
- Stiffness: A feeling of tightness in the hip area, making it difficult to bend or straighten.
- Difficulty walking or limping: Some people may limp when walking because their hips hurt.
But the amazing thing is, some people may have FAI and not show any symptoms . But for many people, symptoms gradually increase over time, especially when the cartilage in the hip is damaged.
How does this pain feel?
Hip Impingement pain usually feels like a dull ache in the hip. Sometimes, the pain can radiate to the groin, buttocks, and upper thigh. Some people say that the pain feels like something is being squeezed from the inside.
This pain is often worse during physical activity, especially exercises that put a lot of pressure on the hip (for example, squatting, lunging, or jumping). It can also be worse when sleeping on one side or sitting in one position for a long time. During these times, the pain can be sharp, stabbing, or stabbing .
Why does Hip Impingement occur?
`Femoroacetabular Impingement` occurs when the bones in the hip joint rub against each other, become jammed, or put too much pressure on each other. The main cause of this is the formation of an extra bone spur on the thigh bone (`femur`) or the hip socket (`acetabulum`) . Often, people are born with these abnormally shaped joints, or these bone spurs can develop naturally over time. This means that it is not something we do on purpose.
Are there types of Hip Impingement?
Yes, doctors divide this `Hip Impingement` into three main types, depending on where and why the parts of the hip joint do not fit together properly:
- Cam impingement: This happens when there is extra bone growth in the head of the thigh bone (femur), the ball-like part. Then, as the hip socket moves, this extra bone gets stuck.
- Pincer impingement: This occurs when extra bone growth develops on the edge of the hip socket (`acetabulum`). The neck of the femur then impinges on this extra bone.
- Combined impingement: Some people can have both `Cam` and `Pincer` types at the same time.
Who is most at risk of developing this?
Anyone can be born with a hip impingement, or it can develop over time. However, some studies have found that men are more likely to have a cam impingement , while women are more likely to have a pincer or combined impingement .
Athletes are more likely to experience symptoms of `Hip Impingement`. This is especially true for those who play sports that put a lot of pressure on the hip (such as football, basketball, dancing, and running). Some studies suggest that more than half of athletes may have this `impingement` condition. This does not mean that athletes are more likely to develop it. However, because they use their hips more often and harder than others, symptoms may appear sooner and they may feel it more . Remember, `FAI` is caused by the natural shape of your hip, and it does not develop because of playing sports.
What complications can occur if left untreated?
If left untreated, FAI can damage your hip joint over time. In addition to worsening symptoms and making it difficult to use or move your hip, this tightness can also cause a tear in the labrum in your hip. The labrum is a ring of cartilage that surrounds the hip socket. It helps keep the joint stable. The extra pressure and friction caused by femoroacetabular impingement can cause this labrum to tear over time (a hip labral tear).
Also, people with `Hip Impingement` are more likely to develop osteoarthritis in that hip, because the cartilage wears down due to prolonged impingement.
How does a doctor recognize this?
A doctor will diagnose Hip Impingement Syndrome by doing a physical exam and special imaging tests . You will need to tell your doctor how long you have had these symptoms and what movements, activities, or postures make them worse (or worse).
Your doctor will use imaging tests to look at your hip and the tissues around it. These tests may include:
- Hip X-ray
- MRI test (MRI - Magnetic Resonance Imaging)
- CT scan (`CT scan - Computed Tomography scan`)
Sometimes your doctor may inject a small amount of a local anesthetic into your hip. If this temporarily relieves pain or stiffness, it's a good sign that you have FAI. This is only a diagnostic aid, and other treatments are used.
Is there a special test for this? (Femoroacetabular Impingement Test)
Yes, there is a special physical test that your doctor will do to check for an `impingement` in your hip. This is also called the `Femoroacetabular Impingement test`. In this test, you will lie on your back. The doctor will lift your leg up to your chest. Then, with your knee bent at 90 degrees (perpendicular to your thigh), your upper leg will be rotated inward, meaning towards the center of your body.
With these positions, your doctor can gently apply pressure to areas of your hip that may be affected by FAI. If you feel pain while doing these movements, you may have hip impingement . This test can be a little uncomfortable, but it is safe . If you feel any severe pain during any part of the test, tell your doctor .
What is the treatment for this?
Your doctor will likely recommend a combination of treatments to control your symptoms and prevent further damage to your hip. The most common treatments are:
- NSAIDs (Nonsteroidal Anti-inflammatory Drugs): These are over-the-counter pain relievers and anti-inflammatories (such as ibuprofen and naproxen) that can be purchased at the pharmacy. These can help reduce pain and swelling.
- Corticosteroids: These are also anti-inflammatory medications, but they must be prescribed by a doctor. Your doctor may also give you a cortisone injection directly into your hip joint. This can quickly reduce pain and inflammation.
- Physical therapy: A physical therapist will teach you exercises to strengthen the muscles around your hip. This will reduce pressure on the hip joint and increase your ability to move your hip.
- Activity modification: You may need to change the way you exercise, or you may need to stop doing certain movements or activities that increase hip pain. For example, stop squatting too deep.
- Surgery: Your doctor may recommend surgery if you have severe symptoms, if they are affecting your quality of life, or if other treatments have not helped. If you have a hip labral tear, you may need surgery. The most common surgery to correct hip impingement is hip arthroscopy . This involves making a few small incisions and using a camera and small instruments. Your surgeon will tell you more about this.
Will Hip Impingement heal completely?
Hip Impingement Syndrome will not go away completely unless you have surgery to correct the shape of your hip. However, for many people, symptoms can be well controlled with other non-surgical treatments.
However, over time, the benefits of nonsurgical treatments may diminish. Talk to your doctor or surgeon about which treatments are best for you and when you should consider surgery.
Hip arthroscopy to correct femoroacetabular impingement is very successful , and most people do not experience long-term side effects. You may need to avoid or modify some exercises or movements, but you should be able to stay active and play sports.
Can FAI be prevented?
Hip impingement is not preventable because it is caused by the natural shape and position of your hip joint. However, the best way to prevent complications like hip labral tears is to start treatment as soon as possible .
When should I see a doctor?
If you have hip pain, stiffness, or difficulty using or moving your hip – especially if these symptoms last more than a few weeks – be sure to see a doctor.
Also, if you are not feeling as good as before, even with medications like NSAIDs or physical therapy, tell your doctor .
What should you ask the doctor?
When you go to see a doctor, it's a good idea to ask these questions:
- What type of `Hip Impingement` do I have? (`Cam`, `Pincer`, or `Combined`?)
- When should I consider surgery? Or how long can I wait without surgery?
- What activities and movements should I avoid that are hard on my hips?
- Am I at increased risk for hip cartilage damage (hip labral tear)?
Finally, a few things to remember
When you find out you have `Hip Impingement`, you may feel relieved on one hand – you now know why your hip has been hurting for so long. But on the other hand, you may also feel sad and regretful – because it is not something you could have done to prevent it, it is because of the way your hip bones naturally developed.
No matter how you feel, this condition called `Hip Impingement (Femoroacetabular Impingement)` responds well to treatment . It may take some time to find a way to control your symptoms, but your doctor will help you make adjustments until you feel better. If you eventually have to have surgery, remember that `Hip arthroscopy` is a minimally invasive and very successful procedure . So there is nothing to be afraid of. The main thing is to not tolerate the pain and seek medical advice immediately.
