If you have pain at the base of your thumb, you may have heard about different surgery options. Doctors sometimes talk about two ways to fix this problem. One is called trapezectomy and the other uses a silicon implant.
This article looks at a study that compared these two surgeries. Researchers wanted to know which one works better. The good news is that both methods helped patients feel better. Let us explore what they found and what it means for you.
Key Findings at a Glance
- Research shows that 19 people with arthritis at the base of the thumb were treated with surgery.
- According to this study, 12 patients had surgery with a silicon implant and 7 had simple trapezectomy.
- Studies indicate that both surgery types gave similar results for pain relief and function.
- The findings suggest that patients can expect good outcomes from either method.

What Is Rhizarthrosis?
You may be wondering what this long word means. Rhizarthrosis is just another name for arthritis at the base of your thumb. This is the joint where your thumb meets your wrist.
Many people with this problem find it hard to pinch, grip, or twist things. Opening a jar can be painful. Turning a key can hurt. Even writing may become difficult.
This condition is also called basal joint arthritis. The basal joint is the one at the very bottom of your thumb. It is one of the most common places to get arthritis in your hand.
What Are the Two Surgery Options?
When pain does not go away with rest or splints, doctors may suggest surgery. Here is where it gets interesting. There are two main ways to fix this joint.
What Is Simple Trapezectomy?
The first method is called simple trapezectomy. This is a surgery where the doctor removes a small bone at the base of your thumb. That bone is called the trapezium.
After the bone is removed, your body fills the space with soft scar tissue. This acts like a cushion. The thumb can move without painful bone rubbing.
What Is the Swanson Silicon Implant Technique?
The second method uses a silicon implant. This surgery is often called the Swanson technique. It is named after the doctor who invented it.
In this surgery, the doctor also removes the trapezium bone. But then the doctor puts a small silicon spacer in its place. This spacer keeps the bones apart and helps the thumb stay stable.
Let us look closer. The silicon implant is like a tiny cushion made of a soft rubbery material. It stays in place and helps your thumb move smoothly.
What Did the Study Find?
Researchers wanted to know which surgery works better. They followed 19 patients who had thumb arthritis. All of these patients had pain and trouble using their thumbs.
According to this study, 12 patients had the Swanson silicon implant surgery. The other 7 patients had simple trapezectomy without an implant.
After the surgeries, the doctors checked how well the patients were doing. They looked at pain levels, hand strength, and how well patients could use their thumbs in daily life.
| Surgery Type | Number of Patients |
|---|---|
| Swanson Silicon Implant | 12 |
| Simple Trapezectomy | 7 |
Here is the important part. Research shows that both surgery types gave similar results. Patients who had the implant did about as well as patients who did not have the implant. Both groups felt less pain. Both groups could use their thumbs better.
This finding surprised some doctors. Many thought the implant would give better results. But the study showed that the simpler surgery worked just as well.
Which Surgery Should You Choose?
You may be wondering which surgery is right for you. This study tells us that both options can help. The choice may depend on other things.
Some doctors prefer simple trapezectomy because it is a shorter surgery. There is no implant that could wear out or cause problems later. Other doctors like the implant because it may help keep the thumb more stable right away.
Your doctor will look at your hand, your age, and how active you are. You will talk together about what is best for you. It is good to know that both surgeries have been shown to work well.
What Should You Ask Your Doctor?
Before you decide, ask your doctor these questions:
- Which surgery do you recommend for my hand?
- How long will recovery take?
- What are the risks of each surgery?
- Will I need hand therapy after surgery?
- How soon can I use my hand again?
Talking openly with your doctor will help you feel more comfortable with your choice.

Frequently Asked Questions
Does trapezectomy work as well as implant surgery?
According to this study, both surgeries gave similar results. Patients who had simple trapezectomy did about as well as patients who had a silicon implant. Both groups had less pain and better thumb function.
What is a silicon implant for the thumb?
A silicon implant is a small soft spacer made of rubbery material. During surgery, the doctor removes the worn out bone at the base of your thumb. Then the doctor puts the implant in its place. This helps keep the bones apart and lets your thumb move smoothly.
How many patients were in the study?
Research shows that 19 patients with thumb arthritis were in this study. Twelve had the silicon implant surgery and seven had simple trapezectomy.
Is one surgery safer than the other?
The study does not give details about safety or side effects. Both surgeries are commonly done and are considered safe when done by trained doctors. Your own doctor can tell you about risks based on your health.
Conclusion
If you have painful arthritis at the base of your thumb, surgery may help. This study looked at two common surgeries. One removes a small bone and leaves the space empty. The other removes the bone and puts a silicon implant in its place.
The good news is that both surgeries helped patients feel better. Studies indicate that you can expect similar results from either method. This gives you and your doctor more choices.
Talk with your doctor about which surgery fits your needs. Ask questions. Learn about recovery time and what to expect. With the right treatment, you can look forward to less pain and a thumb that works better.
