If your thumb pain from rhizarthrosis has not improved with splints, medicine, or other treatments, you may be wondering what comes next. Surgery is one option that can help. This article looks at a study where doctors joined the thumb joint together to stop the pain. This surgery is called arthrodesis. The study shows how doctors used small metal plates to hold the bones in place while they healed. Most patients felt much better after the operation.
Key Findings at a Glance
- Research shows that arthrodesis (joining the thumb bones together) helped all 18 patients feel less pain and use their thumbs better.
- According to this study, doctors used tiny metal plates to hold the bones steady, which let patients start moving their hands sooner.
- Studies indicate that the surgery worked best for patients with stage III arthritis who had tried other treatments first without success.
- Medical evidence from this research shows that 3 out of 18 patients needed a second operation to fix problems, but everyone improved overall.

What Is Rhizarthrosis and Why Does It Hurt So Much?
Rhizarthrosis is a big word that means the joint at the base of your thumb is wearing out. The cushion between the bones is breaking down. This causes the bones to rub together. That rubbing creates pain, stiffness, and swelling.
When this joint gets damaged by arthritis, even simple tasks become hard. Opening jars, turning keys, and holding a pen can all hurt. You may be wondering why this matters. The thumb is used in almost every hand movement. When it hurts, your whole hand feels weak.
Doctors call this condition osteoarthritis of the trapezio-metacarpal joint. That is just another name for the same problem. The trapezium is a small wrist bone that touches the thumb bone. When the cartilage between them wears away, pain starts.
What Is Arthrodesis Surgery?
Arthrodesis is a surgery that joins two bones together so they cannot move anymore. The doctors take away the damaged joint surfaces. Then they put the bones together. Over time, the bones grow into one solid piece.
You may be thinking that sounds scary. Losing movement in your thumb might seem like a bad thing. But here is where it gets interesting. When the joint is very damaged and painful, stopping the movement actually helps. The pain goes away because the bones are no longer rubbing together.
Your thumb can still move at other joints. You can still use your hand for most tasks. The trade is less pain for a small loss of motion. For many people, this is a good trade.
How Did Doctors Use Tiny Plates to Fix the Thumb?
According to this study, doctors used a special technique called micro-plate osteosynthesis. Let us break that down. Micro means very small. Osteosynthesis means putting bones together using hardware.
The doctors in this study chose this method because it holds the bones very steady. When the bones are held firmly in place, patients can start moving their hands sooner. They do not need to wear a cast for as long. Early movement helps the hand stay flexible and strong.
Let us look closer. The surgery involves removing the damaged cartilage and preparing the bone surfaces. Then the doctors position the bones at the best angle for gripping and pinching. The small plate is attached with tiny screws. The metal stays in your body and usually does not cause problems.
Why Is Early Movement Important?
Research shows that starting hand exercises early after surgery helps you recover better. Your muscles stay stronger. Your joints stay more flexible. The plate is strong enough to let you do gentle movements even while the bone is still healing.
This is different from older methods where patients had to keep their thumb completely still in a cast for many weeks. Those patients often had stiff, weak hands after the cast came off.
Who Should Consider This Surgery?
According to this study, the doctors offered arthrodesis to patients who met certain conditions. First, the patient had to have proof of arthritis on an X-ray. The X-ray shows how much the joint is damaged. Doctors use stages to describe how bad the arthritis is. Stage I is mild. Stage III is severe.
Most patients in this study had stage III arthritis. That means their joints were very worn out. The space between the bones was very narrow or gone. The bones might have started to change shape.
Second, the patient had to try conservative treatments first. Conservative means treatments that do not involve surgery. These include:
- Wearing a splint to rest the thumb
- Taking pain medicine or anti-inflammatory drugs
- Getting injections into the joint
- Doing hand therapy exercises
If those treatments did not help enough, then surgery became an option. Studies indicate that surgery is not the first choice. It is for people who have tried other things and still have too much pain to do daily activities.
What Happened to the Patients After Surgery?
Here is where it gets really interesting. The doctors followed 18 patients who had this surgery. Every single one of them said their thumb worked better after the operation. They all felt less pain too. That is a very good result.
The doctors looked at both short-term results and long-term results. Short-term means the first few weeks and months. Long-term means many months or years later. The improvements lasted over time.
Were There Any Problems?
Medical evidence from this research shows that 3 out of the 18 patients needed a second surgery. That is about one in every six patients. The doctors had to go back in to fix something that did not heal right the first time.
The study does not tell us exactly what went wrong in those three cases. But the important thing is that even those patients ended up better after the revision surgery. A revision surgery is when doctors do another operation to correct a problem from the first one.
Even with some patients needing more surgery, the overall success rate was high. All patients improved. That is encouraging news if you are considering this option.
Comparing Different Operations
The doctors mention that there are other ways to treat severe thumb arthritis. They compared arthrodesis to these other surgeries. Each operation has good points and not so good points. Arthrodesis removes pain very well. It makes the thumb stable and strong. But it does take away some motion.
Other surgeries might keep more motion but may not control pain as well. Or they might take longer to heal. The doctors have to choose the best surgery for each patient based on many factors.

Common Questions About Thumb Fusion Surgery
Will I be able to use my thumb normally after arthrodesis?
Research shows that all patients in this study improved their thumb function after surgery. You will not have the exact same motion as before arthritis damaged your joint. But you will have much less pain. Most people can do daily tasks like writing, eating, and dressing without trouble. The thumb is fused in a position that allows you to grip and pinch.
How long does it take to recover from this surgery?
The study does not give exact recovery times. However, the doctors explain that using the small metal plates allows early functional treatment. That means you can start moving your hand and doing gentle exercises sooner than with older methods. Full bone healing usually takes several weeks to a few months.
What happens if the surgery does not work the first time?
According to this study, 3 out of 18 patients needed a revision surgery to fix problems. Medical evidence shows that even after revision, all patients ended up with better thumb function and less pain. Revision surgeries can address issues like bones not joining properly or hardware problems.
Is arthrodesis the only surgical option for severe thumb arthritis?
Studies indicate that there are several surgical options for treating rhizarthrosis. The doctors in this study compared different operations. Arthrodesis is one choice. Other surgeries exist too. Your doctor will help you choose the best option based on your age, activity level, and how damaged your joint is.
Wrapping Up: What This Means for You
If you have severe thumb arthritis that has not responded to conservative treatments, arthrodesis with micro-plate fixation may be worth discussing with your doctor. Research shows that this surgery helped all patients in this study feel less pain and use their thumbs better. The small metal plates hold the bones steady and allow you to start moving your hand earlier.
Most patients did well. A few needed a second surgery. But in the end, everyone improved. That is hopeful news.
Your next step is to talk with your hand surgeon or orthopedic doctor. Bring your X-rays. Ask about all your options. Find out if you are a good candidate for this surgery. Every person is different. What works for one may not be right for another. But now you have more information to guide your conversation.
You deserve to live without constant thumb pain. There are solutions available. Keep asking questions. Keep learning. You are taking the right steps by educating yourself.
