If you have been living with thumb pain at the base of your thumb, you know how hard it can be to open a jar, turn a key, or even hold a pen. Many people with this kind of pain have a condition called rhizarthrosis. Researchers wanted to find out if a new kind of injection works better than the usual steroid shot that doctors have been using for years.
This study compared two different types of injections given directly into the painful thumb joint. One was a special form of hyaluronic acid. The other was a common steroid called triamcinolone. Both groups of patients got two shots over six months. Then doctors tracked their pain and hand function for half a year.
Here are three important things the study found:
- Both treatments helped reduce pain and improve how the thumb works.
- The hyaluronic acid injection gave faster relief and kept working longer than the steroid.
- People who got hyaluronic acid also had less morning stiffness and could do more daily activities.
Key Findings at a Glance
- Research shows that hybrid hyaluronic acid injections provided better pain relief than steroid injections in people with thumb arthritis.
- According to this study, benefits from hyaluronic acid started after one month and lasted through the entire six month follow up period.
- Studies indicate that hyaluronic acid reduced morning stiffness and improved daily activities more than steroid treatment.
- Medical evidence from 100 patients with thumb joint arthritis showed statistically significant improvements in hand function with hyaluronic acid.
- The hybrid formulation of hyaluronic acid called Sinovial H-L was well tolerated and showed a rapid and persistent effect.

What is rhizarthrosis and why does it hurt so much?
This condition can make everyday tasks really difficult. You might feel pain when you grip something. You might notice your thumb feels stiff in the morning. Sometimes the pain can affect how you feel about your life in general.
You may be wondering why this matters so much. Well, your thumb is incredibly important. It helps you grab, pinch, and hold things. When it hurts, almost everything becomes harder.
What did this study actually find?
Doctors in Italy looked back at the medical records of 100 patients who had thumb arthritis. Some of these patients had pain in one thumb. Others had pain in both thumbs. All of them received treatment with injections.
Half of the patients got a treatment called Sinovial H-L. This is a hybrid form of hyaluronic acid. The other half got triamcinolone acetonide, which is a type of steroid medicine that doctors have used for a long time.
Here is where it gets interesting. The doctors measured pain using something called a Visual Analogue Scale, or VAS. This is just a way for patients to rate their pain from zero to ten. They also checked how well the hand worked using a special score called the Functional Index for Hand OA, or FIHOA.
How long did the study last?
Each patient got two injections. Then the doctors checked on them at different times over six months. They looked at pain levels, how well the hand worked, morning stiffness, and quality of life.
How did the two treatments compare?
According to this study, both treatments helped. But the hyaluronic acid group did better in several important ways.
Let us look closer at the details. After just one month, the people who got hyaluronic acid had less pain than the people who got steroids. This difference was not just a little bit better. It was what scientists call statistically significant. That means the difference was big enough that it probably was not just by chance.
The benefits kept going for the whole six months. The hyaluronic acid group continued to feel less pain and their thumbs worked better compared to the steroid group.
What about other symptoms?
Research shows that hyaluronic acid also helped with morning stiffness. Many people with arthritis wake up with stiff joints. The stiffness usually gets better as the day goes on. The hyaluronic acid treatment reduced how long this stiffness lasted each morning.
The study also looked at daily activities. Doctors used something called the Health Assessment Questionnaire, or HAQ. This asks patients if they can do things like dress themselves, get in and out of bed, or lift a cup. The hyaluronic acid group showed bigger improvements in these everyday tasks.
There was also a measure of overall quality of life called the SF-36. This looks at physical health and mental health. The physical part got better for people who received hyaluronic acid.
| Outcome Measured | Hyaluronic Acid Group | Steroid Group |
|---|---|---|
| Pain relief at one month | Significantly better | Improved |
| Pain relief at six months | Significantly better | Improved |
| Hand function | Significantly better | Improved |
| Morning stiffness | Decreased significantly | Not reported as significant |
| Daily activities | Significantly improved | Not reported as significant |
What do these results mean for you?
If you are dealing with thumb pain from arthritis, you might be thinking about your treatment options. This study suggests that hyaluronic acid injections could be a good choice.
Steroid shots have been the standard treatment for a long time. They work quickly and can give relief. But the effects often do not last very long. Some people also worry about side effects from repeated steroid injections.
Hyaluronic acid seems to offer a different kind of help. It works a bit slower at first, but the effects last longer. It also seems to help with more than just pain. It can improve how well your thumb moves and how stiff it feels in the morning.
Is hyaluronic acid safe?
According to medical evidence presented in this study, the hybrid hyaluronic acid was well tolerated. That means most people did not have serious problems with it. The study called it a valid alternative to steroid injections.
Of course, every person is different. What works well for one person might not work the same way for another. That is why it is so important to talk with your doctor about what is right for you.

Frequently Asked Questions
How many injections would I need?
According to this study, patients received two injections over a period of six months. The exact timing and number of injections may vary based on your specific situation and what your doctor recommends.
How soon will I feel better after a hyaluronic acid injection?
Research shows that patients in this study started to see significant improvement after one month. The benefits continued to grow over the six month follow up period. This means it may take a few weeks before you notice the full effect.
Can hyaluronic acid injections replace surgery?
This study looked at injections as a treatment option, but it did not compare them to surgery. Hyaluronic acid may help you avoid or delay surgery, but it depends on how severe your arthritis is. Your doctor can help you decide if injections are enough or if you might need other treatments.
Are steroid injections still a good option?
Studies indicate that steroid injections do help reduce pain and improve function in thumb arthritis. They are still recommended by medical experts. This study just suggests that hyaluronic acid may work better for some people and may last longer. Both treatments have a place in managing thumb arthritis.
Wrapping It All Up
Living with thumb pain can be frustrating. Simple tasks that other people take for granted can become real challenges. But research like this gives us hope that better treatments are available.
According to this study, hybrid hyaluronic acid injections may offer better and longer lasting relief than traditional steroid shots. They can help reduce pain, improve how your thumb works, and make daily activities easier.
If you have been struggling with thumb arthritis, it might be worth asking your doctor about hyaluronic acid injections. Bring this information with you. Talk about your options. Together, you can decide what treatment plan is best for you.
Remember, you do not have to live with constant pain. There are treatments that can help you feel better and do more of the things you love.
