If you have been dealing with thumb pain from arthritis at the base of your thumb, you are probably searching for solutions that actually work. You may have heard about different surgical options. One of them uses a small device called a Mini TightRope.
In this article, we will look at a study from Germany that tested this device on 31 patients with thumb arthritis. We will explore what the doctors found, how well it worked, and what you should know if you are thinking about this treatment.
Key Findings at a Glance
- Research shows that 74.2% of patients achieved good or very good results after the surgery.
- According to this study, doctors removed a small bone in the thumb and used a special device to hold the thumb in place.
- Studies indicate that 2 out of 31 patients needed to have the device removed because of pain and thumb bone movement.
- The distance between thumb bones decreased over time, even with the device in place.
- The Mini TightRope device costs about 225 Euros per patient.

What is rhizarthrosis and why does it hurt?
Rhizarthrosis is a big word for arthritis at the base of your thumb. This is the joint where your thumb connects to your wrist.
You may feel pain when you pinch, grip, or twist things. Simple tasks like opening a jar or turning a key can become hard.
Many people live with this pain for years before looking into surgery. If you have tried splints, medicines, and hand therapy without enough relief, your doctor might talk to you about surgery.
What did doctors do in this study?
Let us look closer at what the doctors did in Germany.
According to this study, doctors treated 31 patients. Most of them were women (26 women and 5 men). The average age was about 58 years old.
The surgery had two main steps:
- Step one: The doctors removed a small bone called the trapezium. This bone sits at the base of your thumb. Removing it is called trapezectomy. It creates space so the bones do not rub together anymore.
- Step two: The doctors used a Mini TightRope device to hold the thumb bone in a good position. Think of it like a tiny suspension bridge for your thumb.
Here is where it gets interesting. The Mini TightRope is a small implant. It uses strong threads to connect bones and keep them stable. The device costs about 225 Euros.
How well did the treatment work?
Research shows that most patients felt better after surgery.
The doctors checked on patients about 13 and a half months after surgery. Some patients came back as early as 6 months. Others came back up to 22 months later.
The doctors used a special scoring system called the Buck-Gramcko score. This score measures pain, strength, movement, and how well you can use your hand.
Here are the results:
| Result | Percentage of Patients |
|---|---|
| Good or very good | 74.2% |
| Satisfactory or poor | 12.9% |
This means that about 3 out of every 4 patients got good relief from their pain. They could use their hands better. They felt happier with their thumbs.
But not everyone did well.
What went wrong for some patients?
According to this study, 2 patients had serious problems. The Mini TightRope device had to be taken out after 6 to 7 months.
Why? The thumb bone moved upward. This is called proximalisation. When this happened, the patients felt strong pain. The pain happened both when they rested and when they moved their thumb.
You may be wondering why this matters. If the device does not hold the thumb bone in place, the surgery does not work as planned. The patient ends up with pain again.
What happened over time?
The doctors measured the space between two bones in the thumb. One is called the scaphoid. It is a small wrist bone. The other is the first metacarpal. This is the long bone in your thumb.
Right after surgery, the space between these bones was about 11.1 millimeters on average. That is a good amount of space.
But when doctors checked again months later, the space had shrunk. It was now only about 5.3 millimeters on average. Some patients had almost no space left at all.
| Time | Average Space (millimeters) |
|---|---|
| Right after surgery | 11.1 |
| At follow up (average 13.5 months) | 5.3 |
This shows that even with the Mini TightRope in place, the thumb bone can still move closer to the wrist over time. This is something doctors call proximalisation.
Why does this happen? The body heals and scars form. Muscles and tendons pull on the thumb. Over time, these forces can move the bone.
Does this mean the surgery failed?
Not always. Many patients still felt good even though the space got smaller. The important thing is how the thumb feels and works, not just what the X-ray shows.
But it does raise questions. If the device cannot fully prevent the thumb from moving, is it worth the extra cost?

Frequently Asked Questions
What is a Mini TightRope device?
A Mini TightRope is a small implant used in thumb surgery. It uses strong threads to connect and stabilize bones. Doctors use it to hold the thumb in place after removing a damaged bone. It works like a suspension bridge inside your hand.
How long does recovery take after this surgery?
According to this study, doctors checked on patients between 6 and 22 months after surgery. Most patients were evaluated around 13 and a half months later. Recovery time varies from person to person. Your doctor will guide you on what to expect.
Will my thumb bone stay in place after surgery?
Research shows that the thumb bone can move closer to the wrist over time, even with the device. In this study, the space between bones decreased from 11.1 millimeters to 5.3 millimeters on average. However, many patients still had good results and less pain.
Is this surgery right for me?
This depends on your specific situation. Talk to your hand surgeon. Ask about the benefits and risks. Ask about other options too. This study shows that most patients did well, but some had problems. Your doctor can help you decide what is best for your thumb.
Conclusion
According to this study, the Mini TightRope device can help many people with thumb arthritis. About 74% of patients felt much better after surgery. They had less pain and could use their hands more easily.
But the device is not perfect. Some patients had the device removed because of pain and bone movement. The thumb bone moved upward in some cases, even with the device in place. And the device costs extra money compared to other options.
If you are thinking about surgery for your thumb arthritis, talk openly with your doctor. Ask about this option and others. Ask about success rates, risks, and costs. Every person is different. What works well for one person may not be the best choice for another.
You deserve to have all the facts before you decide. Your thumb pain is real. Your concerns matter. Take your time. Ask questions. Find the treatment path that feels right for you.
