If your thumb hurts when you grip, pinch, or twist, you might have rhizarthrosis. That is a big word for arthritis in your thumb joint. When the pain becomes too much, surgery can help. But which surgery works best?
A new study looked at three different surgeries doctors use to fix this problem. Researchers wanted to know which one gives the best results. They looked at 289 patients who had one of three operations. Let us see what they found.
Key Findings at a Glance
- Research shows that no single surgery is better than others for pain relief, hand function, or patient satisfaction.
- According to this study, arthroplasty (joint replacement) showed good results over time compared to other common techniques.
- Studies indicate that trapeziectomy with tendon interposition did not improve strength or function more than arthrodesis.
- Medical evidence reveals that trapeziectomy was linked to more cases of joint problems that needed another surgery.
- All three surgeries can help with thumb arthritis pain, but each has different risks and benefits.

What is rhizarthrosis and why does it hurt?
You may be wondering why this matters. Your thumb does a lot of work every day. You use it to open jars, turn keys, and hold a pen. When the joint hurts, even small tasks can feel hard.
Many people try creams, splints, and medicines first. But sometimes the pain does not go away. That is when doctors talk about surgery.
What did this study look at?
Researchers wanted to answer a simple question. Which surgery gives the best results for people with rhizarthrosis? They looked at many published studies. They gathered information from 289 patients who had surgery.
Here is where it gets interesting. They did not just look at one kind of surgery. They compared three different types. This kind of research is called a systematic review with meta-analysis. That means they pulled together results from many studies to find patterns.
The team searched medical databases up to June 2024. They did not limit their search by language. They wanted to include all the evidence they could find.
What are the three surgeries?
According to this study, doctors use three main surgeries to treat rhizarthrosis. Let us look at each one.
Trapeziectomy with tendon interposition
In this study, 63 patients had this surgery. It has been a common choice for many years.
Arthrodesis
In this study, 70 patients had arthrodesis. This surgery is strong and stable. But it does take away some thumb movement.
Arthroplasty
In this study, 156 patients had arthroplasty. This was the largest group.
What did the researchers find?
Let us look closer at what the study showed.
How did arthroplasty perform?
Research shows that arthroplasty had good long term results. Patients who had joint replacement did well over time. The study compared arthroplasty to the other two techniques. It held up well in the comparison.
This does not mean it is perfect. But it does mean that replacing the joint can be a good choice for some people.
How did trapeziectomy compare?
According to this study, trapeziectomy with tendon interposition did not show a clear advantage. When researchers compared it to arthrodesis, they found something important. Trapeziectomy did not improve strength or function more than fusing the joint.
Here is where it gets more interesting. Trapeziectomy was also linked to more problems. Some patients had issues with the joint space collapsing. When this happened, they needed another surgery to fix it.
Medical evidence reveals that cases of joint reduction failure were more common with trapeziectomy. Joint reduction failure means the space where the bone was removed shrinks too much. This can cause pain and weakness to return.
Which surgery is best overall?
The main conclusion may surprise you. No surgical technique is superior to another in terms of pain, physical function, and the patient’s overall assessment. This is what the researchers found when they looked at all the data together.
What does this mean? It means that all three surgeries can help. They all reduce pain. They all improve function. And patients are generally happy with the results.
But each surgery has different risks and benefits. Your doctor will help you choose the one that fits your situation best.
| Surgery Type | Number of Patients | Key Findings |
|---|---|---|
| Trapeziectomy with tendon interposition | 63 | More joint problems and repeat surgeries |
| Arthrodesis | 70 | Stable but reduces thumb movement |
| Arthroplasty | 156 | Good long term results |
About this site
We know medical research can feel confusing. Our goal is simple. We take published scientific studies about thumb pain and rhizarthrosis and explain them in plain language. We only use real research articles, not opinions or guesses. This way, you get accurate information you can trust. Feel free to explore more articles on our site to learn about other treatments, causes, and ways to manage thumb arthritis.
Frequently asked questions
Does one surgery hurt less than the others?
According to this study, all three surgeries helped reduce pain about the same amount. No surgery was clearly better for pain relief. Your pain level after surgery depends on many things, including how severe your arthritis is and how well you heal.
Will I be able to use my thumb normally after surgery?
Research shows that all three surgeries improve hand function. Arthroplasty and trapeziectomy let your thumb keep more movement. Arthrodesis limits movement because the joint is fused. But it can still give you a strong, stable thumb for daily tasks.
Can the surgery fail and need to be done again?
Studies indicate that trapeziectomy with tendon interposition had more cases where the joint space collapsed. This sometimes led to another surgery. Arthrodesis and arthroplasty can also have problems, but the study found fewer cases of repeat surgery with these techniques.
How do I choose which surgery is right for me?
Your doctor will look at your age, activity level, and how damaged your joint is. They will also think about what you want to be able to do with your thumb. This study shows that all three surgeries can work well. The best choice depends on your personal situation.
What does this mean for you?
If you are living with thumb arthritis, this research brings good news. You have options. All three surgeries can help reduce your pain and improve your hand function.
The study did not find one clear winner. But it did find that arthroplasty showed good results over time. It also found that trapeziectomy may have more risk of needing a second surgery.
The most important step is to talk with your doctor. They can explain which surgery might work best for you. They will think about your health, your goals, and what you need your thumb to do.
You do not have to live with constant thumb pain. Help is available. And now you know a little more about what the research says.
