If you have thumb pain from rhizarthrosis and are thinking about surgery, you might wonder what happens next. After surgery, the way you protect and move your thumb matters a lot. This article explains a study that looked at three different ways to care for your thumb after a special type of surgery.
Key Findings at a Glance
- A short thumb brace worked better than a long brace or no brace after thumb surgery
- Pain scores improved by 5 points in all groups 12 weeks after surgery
- Patients with short braces or no braces cut their disability scores in half
- Long braces caused more problems with grip strength and pinch strength
- Not wearing a brace did not lead to more pain than wearing one
Here are the three key points you need to know:
- A short thumb brace helps your thumb heal while still letting other thumb joints move
- A long thumb brace can actually slow down your recovery and make your hand weaker
- Going without a brace does not cause more pain, but a short brace gives the best results

What is rhizarthrosis and why does it hurt?
When you have rhizarthrosis, moving your thumb hurts. Gripping things becomes hard. Even small tasks like opening a jar or turning a key can cause pain.
Sometimes medicine and therapy do not help enough. When that happens, doctors may suggest surgery. One type of surgery is called interposition arthroplasty (a type of thumb joint surgery). This is when the surgeon removes the damaged part of the joint and puts something soft in its place to cushion the bones.
You may be wondering why this matters. Surgery is just the first step. What you do after surgery is just as important for getting better.
What did this study look at?
According to this study, researchers wanted to answer two big questions. First, does wearing a thumb brace help after surgery? Second, if you do wear a brace, should it be long or short?
The study followed 42 patients who had thumb surgery. All of them had the same type of surgery called the Weilby method (Weilby method). After surgery, everyone wore a hard cast for two weeks. Then they were split into three groups.
Each group got occupational therapy for 12 weeks. Occupational therapy means working with a therapist who helps you learn to use your hand again.
What were the three groups?
Research shows that the way you protect your thumb after the cast comes off can make a big difference. Here is where it gets interesting. The patients were divided like this:
| Group | Type of Support | What It Does |
|---|---|---|
| Group I | Long orthotic thumb device | Holds the thumb and several thumb joints still |
| Group II | Short orthotic thumb device | Only holds the operated joint still, other joints can move |
| Group III | No orthotic thumb device | No brace at all after the cast |
All three groups wore their brace (or no brace) for 4 weeks. Then the researchers checked how everyone was doing at 6 weeks and 12 weeks after surgery.
What did the researchers find?
Let us look closer. All three groups got better over time. Pain went down. Hand function improved. But the groups did not improve at the same speed or in the same way.
Pain Levels
According to this study, everyone felt less pain after 12 weeks. The researchers used a pain scale called the VAS Pain Score. This is where you point to a line to show how much pain you feel. The pain score improved by 5 points in all groups.
Here is something surprising. Patients who wore no brace did not have more pain than those who wore a brace. Many people worry that not wearing a brace will hurt more. This study showed that is not true.
Hand Function and Disability
Research shows that the Quick DASH score measures how hard it is to do everyday tasks with your hand. A lower score means you can do more things easily.
Patients with the short brace or no brace cut their Quick DASH scores in half. That means their hand disability got much better. Patients with the long brace did not improve as much.
Strength and Movement
Grip strength is how hard you can squeeze something. Pinch strength is how hard you can pinch your thumb and finger together. Both are important for daily activities.
Patients who wore the long brace had the weakest grip and pinch strength after 12 weeks. Patients who wore the short brace did much better. They also had better movement in their thumb joints.
The short brace group showed the best improvement in several areas. They had less pain, better Quick DASH scores, more movement in the operated joint, and better thumb function overall.
Why is a short brace the best choice?
You may be wondering why a short brace works better than a long one. The answer is about movement.
A short brace only holds still the joint that was operated on. This is the carpometacarpal joint at the base of the thumb. All the other thumb joints can still move freely. This means you can bend and straighten your thumb while the operated joint heals.
Movement is important. When you move your thumb, the muscles stay strong. The tendons stay flexible. Blood flows to the area and brings healing nutrients.
A long brace holds many joints still. This protects the operated joint, but it also stops you from moving the rest of your thumb. When joints do not move, they get stiff. Muscles get weak. This makes it harder to use your hand later.
The study showed that patients with long braces had more trouble with grip strength, pinch strength, and overall hand function 12 weeks after surgery.
What about no brace at all?
Patients who wore no brace also did well. They did not have more pain. Their disability scores improved. But the short brace group still did the best overall.
A short brace gives you the best of both worlds. It protects the healing joint while letting the rest of your thumb move and stay strong.

Frequently Asked Questions
Do I really need a brace after thumb surgery?
According to this study, wearing a short brace gives the best results. It helps protect the joint that was operated on while letting the rest of your thumb move. This leads to better hand function and strength after 12 weeks. Not wearing a brace does not cause more pain, but a short brace helps you recover faster and more fully.
How long should I wear the brace?
Research shows that wearing a short brace for 4 weeks after the initial 2 week cast gives good results. During this time, you also work with an occupational therapist who helps you learn safe movements and exercises.
Will I lose strength if I wear a brace?
Studies indicate that a long brace that holds many joints still can lead to weakness. But a short brace that only holds the operated joint still allows the rest of your thumb to move. This helps you keep your strength. Patients with short braces had better grip and pinch strength than those with long braces.
What is occupational therapy and why do I need it?
Occupational therapy means working with a trained therapist who teaches you exercises and safe ways to use your hand. According to medical evidence, therapy after thumb surgery is very important for a successful outcome. The therapist helps you regain movement, strength, and the ability to do everyday tasks.
What does this mean for you?
If you are planning to have thumb surgery for rhizarthrosis, this research gives you helpful information. Talk to your doctor about using a short thermoplastic thumb brace after your cast comes off.
A short brace protects the joint that was operated on but lets the rest of your thumb move. This leads to less pain, better hand function, and stronger grip and pinch after 12 weeks.
Remember that occupational therapy is also very important. Working with a therapist helps you heal safely and get back to the activities you love.
Every person is different. Your doctor knows your situation best. Use this information to have a good conversation about what is right for you.
