Do you struggle with thumb pain from a condition called rhizarthrosis? If you do, you’re not alone. Many people deal with this problem, and it can make simple tasks like opening a jar or writing a note really hard.
But good news—recent research shows a treatment called hyaluronic acid injections could help reduce pain and inflammation in the thumb joint.
Let’s walk through three key points from the study:
- The injections work best when guided with ultrasound technology.
- The treatment can reduce pain as soon as two weeks after starting.
- Some benefits last for at least six months!
Ready to dig deeper into how this treatment works? Let’s explore.

What is rhizarthrosis?
Rhizarthrosis is another name for thumb arthritis. It’s a condition where the joint at the base of your thumb (called the trapeziometacarpal joint) becomes worn out over time. Your cartilage, which is like a cushion between your bones, can break down. This can cause pain and make it tough to move your thumb.
How does hyaluronic acid help?
You may be wondering, what exactly is hyaluronic acid? Hyaluronic acid, or HA, is a substance that naturally occurs in your body. It helps keep your joints lubricated. Think of it like oil for a creaky door hinge—it reduces friction and makes movement smoother.
In this treatment, a special high-quality version of HA is injected into the thumb joint. It’s not something you swallow like a pill. Instead, doctors use ultrasound, a machine that creates images from sound waves, to guide the injection right to the hurting joint. This ensures the HA goes exactly where it’s needed most.
What did the study find?
Here is where it gets interesting. Researchers tested HA injections on 32 thumb joints in 16 people. They gave each person three shots over three weeks, one every week.
So, what happened? Here are the key findings from the study:
- The people in the study felt less pain just two weeks after starting the treatments. This was measured with something called a “visual analog scale,” which is a simple tool to rate pain levels on a scale from 0 to 10.
- Even after 24 weeks (about six months), the pain relief was still there, though not as strong as it was after the first few weeks.
- Doctors also checked for swelling inside the thumb joint. They used ultrasound to see if the swelling decreased. They noticed there was less blood flow to the swollen area after the treatment, which is a good sign that inflammation went down. However, by week 24, the improvement was less noticeable.
- A tool called the Dreiser’s index was used to track how easy it was for patients to use their hands. The scores showed steady improvement over time, and the better function lasted six months.
The study shows that HA injections can really help reduce pain and make it easier to move your thumb. But keep in mind, not all the benefits lasted long-term. This means it might help to continue monitoring this treatment over time or combining it with other methods to see even better results.
Frequently Asked Questions
-
What is a hyaluronic acid injection?
It’s a procedure where doctors inject a lubricating fluid (hyaluronic acid) to help joints move more smoothly and hurt less.
-
Does it hurt to get these injections?
Doctors use a machine called an ultrasound to guide where to inject the liquid. This ensures the procedure is safe and accurate, which can help minimize discomfort.
-
Will my pain go away forever after this treatment?
Not forever, but the study found that pain decreased significantly for about six months after treatment.
Final thoughts
Living with thumb pain can be tough, but treatments like hyaluronic acid injections may provide the relief you’re looking for. Studies show they can reduce pain, ease inflammation, and help you feel more comfortable using your hands.
If you’re considering this treatment, talk with your doctor to discuss your options. Keep in mind that every person’s body is different, so the results might vary. Combining this treatment with other care options might help even more.
