If you have thumb pain at the base of your thumb, you may have heard about surgery that removes a small bone called the trapezium. This bone sits right where your thumb meets your wrist. But what if there was a way to keep that bone and still get relief?
This article looks at a study about treatments that save your thumb joint instead of taking parts of it out. These treatments might help you in the early stages of thumb arthritis.
Here are three key points:
- Removing the trapezium bone has been the most common surgery for thumb arthritis for a long time.
- Taking out that bone can lead to problems like a shorter thumb, weaker pinch strength, and less stable thumb movement.
- Joint saving treatments may help you feel better and work better without needing to remove any bone.
Key Findings at a Glance
- Trapezium resection (removing the trapezium bone) has been the gold standard surgery for thumb carpometacarpal joint arthritis.
- Removing the trapezium can cause the thumb to become shorter, pinch strength to weaken, and thumb stability to decrease.
- Joint preservation techniques can be used in the early stages of thumb arthritis.
- These joint saving treatments aim to reduce pain, help you return to normal activities, and delay the need for more invasive surgery.

What is thumb arthritis?
Your thumb is amazingly mobile. It can move in many directions. That freedom of movement comes from a special joint at the base of your thumb. This joint is called the carpometacarpal joint, or CMCJ for short.
Over time, the smooth cartilage that cushions this joint can wear away. When that happens, bone rubs on bone. This condition is called osteoarthritis. When it happens at the base of your thumb, doctors call it CMCJ OA or rhizarthrosis.
You may be wondering why this matters. When the cartilage is gone, the joint becomes painful and stiff. Simple tasks like opening a jar or turning a key can hurt.
What has been the usual surgery?
According to this study, the most common surgery for thumb arthritis has been trapezium resection. That means the surgeon removes the trapezium bone completely.
Sometimes doctors add a step called tendon suspension arthroplasty. In that procedure, the surgeon uses a piece of tendon to hold the thumb in place after the bone is removed. This combination has been considered the gold standard treatment for many years.
Many patients have found relief with this surgery. It can reduce pain and help the thumb move more easily. But it is not perfect.
What problems can happen after removing the trapezium?
Here is where it gets interesting. Research shows that removing the trapezium bone may lead to some unwanted effects.
The study explains that taking out the trapezium can cause the first metacarpal (your thumb bone) to sink down or become shorter. Doctors call this subsidence. When your thumb becomes shorter, it can change how your hand works.
The study also points out that trapezium removal may lead to reduced pinch strength. That means it might be harder to pinch things tightly between your thumb and fingers. You might notice this when you try to pick up small objects or hold a pen.
Another problem is thumb instability. When the trapezium is gone, your thumb might feel less steady or wobble more than it should. This can make it harder to do tasks that need precise thumb movements.
Let us look closer at why these problems happen. The trapezium acts like a platform that supports your thumb. When that platform is gone, your thumb loses some of its natural support. Your hand has to work harder to keep your thumb in the right position.
What are joint saving treatments?
Joint preservation techniques are treatments that keep your bones intact. Instead of removing the trapezium, these treatments try to protect it and the joint around it.
According to this study, joint preservation techniques may be used in the early stages of CMCJ OA. The key word here is early. When arthritis is just starting, there may still be enough healthy cartilage and bone to work with.
The study describes three main goals of these joint saving treatments:
- Promote pain relief so you can feel better and use your hand more comfortably.
- Help you return to function so you can do the activities you need and enjoy.
- Delay more invasive procedures like trapezium resection so you can avoid bigger surgery for as long as possible.
You may be wondering what these treatments actually are. The study does not list every specific technique. But the idea is to use less aggressive methods first. These might include injections, braces, physical therapy, or minor surgical repairs that fix damaged tissue without removing bone.
By keeping your joint intact, you keep the natural structure of your thumb. That can help you maintain better strength, stability, and length in your thumb.
Why does timing matter?
The study emphasizes that joint preservation works best in the early stages of thumb arthritis. This is important.
In the early stages, the damage is not too severe. There is still cartilage left. The bones are still in good shape. At this point, treatments that protect and support the joint can make a real difference.
If you wait too long, the joint may be too damaged to save. Then more invasive surgery may be the only option. That is why catching thumb arthritis early and talking to your doctor about joint saving options can be so valuable.

Frequently Asked Questions
What is trapezium resection?
Trapezium resection is a surgery where the doctor removes the trapezium bone at the base of your thumb. This bone is part of the joint that allows your thumb to move. Removing it can relieve pain from arthritis, but it may also cause your thumb to become shorter or less stable.
Can joint saving treatments really help with thumb arthritis?
According to this study, joint preservation techniques may help you feel less pain and return to normal activities in the early stages of thumb arthritis. These treatments aim to protect your joint and delay the need for more invasive surgery.
What does it mean when my thumb becomes shorter after surgery?
When the trapezium bone is removed, the thumb bone can sink down into the empty space. This is called subsidence. It makes your thumb look and feel shorter. It can also affect how well your thumb works and how strong your pinch is.
When should I consider joint saving treatments?
Joint preservation techniques work best in the early stages of thumb arthritis. If your arthritis is caught early, these treatments may help you avoid or delay bigger surgery. Talk to your doctor about whether your arthritis is at a stage where joint saving treatments could help you.
Conclusion
If you have thumb pain or early thumb arthritis, you have options. Removing the trapezium bone has been the go to surgery for many years. But this study reminds us that taking out the trapezium can lead to a shorter thumb, weaker pinch, and less stability.
Joint saving treatments offer another path. These techniques aim to keep your joint intact, reduce your pain, and help you return to the activities you love. They work best when your arthritis is still in the early stages.
Talk to your doctor about where you are in the journey with your thumb arthritis. Ask if joint preservation might be right for you. The more you know, the better choices you can make for your hand and your life.
