If you have pain near your thumb and wrist, you may have heard about a condition that affects the tendons in your thumb. Sometimes surgery is done to help with this pain. But what happens when that surgery causes a new problem?
This article explains a study that looked at people who had surgery for thumb tendon pain and then needed another surgery because their tendons became unstable. Here are three important things you should know:
- Surgery to release tight tendons in the thumb can sometimes make those tendons too loose.
- Doctors can rebuild the supporting structure that holds the tendons in place.
- Fewer surgeries usually mean better results.
Key Findings at a Glance
- Research shows that 10 patients needed surgery to fix unstable thumb tendons after their first surgery.
- According to this study, patients who had only one or two surgeries total had good to excellent results.
- Studies indicate that six patients had poor results, and four of them had more than two surgeries on the same area.
- Minor instability remained in six cases even after the repair surgery.

What Is the Problem This Study Looked At?
Your thumb has special tendons that help you move it. Tendons are like strong cords that connect your muscles to your bones. Near your wrist, these tendons pass through a tunnel called the first extensor compartment. Think of it like a small tube that the tendons slide through.
Doctors often do surgery to help this problem. They open up the tight tunnel to give the tendons more room. This is called decompression. It means releasing pressure.
But here is where it gets interesting. Sometimes when doctors open that tunnel, the tendons become too loose. They can slip out of place. This is called instability. The tendons do not stay where they should be when you move your thumb.
How Do Doctors Know the Tendons Are Unstable?
According to this study, doctors use a special test called the WHAT test. This stands for wrist hyperflexion and abduction of the thumb. Let me explain that in simple words.
The doctor asks you to bend your wrist forward as far as it will go. At the same time, you move your thumb away from your hand. If your tendons are unstable, they will pop out of place during this test. You can actually see or feel them moving where they should not move.
What Happened in This Study?
Researchers looked at the medical records of 10 patients. All of these people had the same journey. First, they had surgery to fix their painful thumb tendons. Then, after that surgery, their tendons became unstable and caused new problems. So they needed another surgery to fix the instability.
Let us look closer. The second surgery was different from the first. The doctors did not just open the tunnel again. Instead, they rebuilt the tunnel using tissue from another part of the body. This tissue is called a retinacular graft. Think of it like using a small piece of strong fabric to create a new holder for the tendons.
The doctors used a technique that was modified from a method used in another part of the hand. They checked how well this worked by examining the patients. They also used ultrasound to look at the tendons. Ultrasound uses sound waves to create pictures inside your body without any cuts or radiation.
The researchers also gave the patients questionnaires. These are sets of questions that help measure how well your hand works and how much pain you feel. The questionnaires were validated, which means other scientists have tested them and found they give reliable answers.
What Did the Researchers Find?
You may be wondering why this matters. The results show us something important about how many surgeries someone has on the same area.
Who Had Good Results?
Research shows that four patients had good to excellent functional outcomes. Functional outcome means how well your hand works after surgery and how much it improves your daily life.
All four of these patients had something in common. They had a maximum of two surgical procedures performed on the first extensor compartment. That means they had their first surgery to open the tunnel, and then the second surgery to rebuild it. They did not need more surgeries after that.
Who Had Poor Results?
According to this study, six patients had poor functional outcomes. Their hands did not work as well after the surgery. They still had problems.
Four of these six patients had more than two surgical procedures on the same area. That means they had surgery three or more times on the same spot.
| Number of Surgeries | Outcome | Number of Patients |
|---|---|---|
| Two or fewer | Good to excellent | 4 |
| More than two | Poor | 4 (out of 6 with poor results) |
What About the Instability?
Studies indicate that six patients still had minor residual instability. Residual means leftover. So even after the surgery to rebuild the tunnel, some patients still had a little bit of looseness in their tendons. This happened in both groups, the ones with good results and the ones with poor results.
This tells us that the surgery helped but did not always make everything perfect. The tendons were more stable than before the second surgery, but not completely stable in everyone.
Why Does This Matter for You?
If you are dealing with thumb pain, this research gives you important information. Surgery can help with painful, swollen thumb tendons. But like all surgeries, it can sometimes cause new problems.
Here is where it gets interesting. The number of times you have surgery on the same spot seems to matter a lot. Having more surgeries does not always mean better results. In fact, this study suggests the opposite. People who had fewer surgeries did better.
This does not mean you should never have surgery. It means you and your doctor should think carefully about each step. If you do need surgery and then have instability afterward, a reconstruction surgery can help. But it works best if you have not had too many surgeries already.
What Should You Think About?
According to medical evidence, you should ask your doctor these questions:
- What are all my treatment options before surgery?
- What could go wrong with the surgery?
- How will you check if my tendons become unstable?
- If I need a second surgery, what are the chances it will help?
Remember, every person is different. What happened in this study might not be exactly what will happen to you. But knowing the possibilities helps you make better choices.

Common Questions
What is tendon instability after thumb surgery?
Tendon instability means the tendons in your thumb do not stay in their proper place. After surgery to release tight tendons, the supporting structure can become too loose. The tendons can then slip or pop out of position when you move your thumb. This can cause pain, weakness, and trouble using your hand.
Can doctors fix unstable tendons?
Research shows that doctors can rebuild the structure that holds your tendons in place. They use tissue from another part of your body to create a new tunnel or holder for the tendons. In this study, 10 patients had this type of surgery. Some had good results and some had poor results. The outcome seemed to depend on how many surgeries they had already had on the same spot.
How many surgeries are too many?
According to this study, patients who had two or fewer surgeries on their thumb tendons had better outcomes. Those who had more than two surgeries were more likely to have poor results. This suggests that keeping the number of surgeries low is important for the best outcome.
Will the instability go away completely?
Studies indicate that some instability may remain even after reconstruction surgery. In this study, six out of 10 patients still had minor instability after their surgery to rebuild the tendon tunnel. However, the surgery still helped many patients by making the tendons more stable than they were before.
The Bottom Line
Surgery for painful thumb tendons can sometimes cause the tendons to become too loose. When this happens, doctors can do another surgery to rebuild the structure that holds the tendons in place.
This study shows that this type of reconstruction can work well for some patients. The best results happened in people who had fewer total surgeries on the same area. More surgeries did not lead to better outcomes.
If you have thumb pain, talk openly with your doctor about all your options. Ask about the risks and benefits of surgery. If you do have surgery and develop problems afterward, know that there are treatments available. But also know that the best approach is often the simplest one that works.
Your thumb is precious. It helps you do so many things every day. Taking care of it means making informed choices with your medical team.
