If you have severe thumb arthritis, you know how much pain it can cause in daily tasks. This article looks at a new surgery. Doctors rotated the bones and joints at the base of the thumb to ease pain and rebuild strength.
Here are three important things you should know:
- Eight patients had a surgery that rotated the thumb joints by 180 degrees.
- All eight patients had restored motion and painless pinch strength.
- The surgery kept the blood supply alive, which helped the bones heal well.
Key Findings at a Glance
- Surgery was performed on eight patients with severe thumb arthritis since January 1998.
- The surgical technique involved rotating the thumb joints 180 degrees while keeping blood vessels intact.
- Three patients had good results, and five patients had excellent results.
- All patients regained complete thumb motion, stability, and painless pinch strength.
- Active thumb movement began four weeks after surgery, with hand therapy starting at six weeks.

What Is Rhizarthrosis and Why Does It Hurt So Much?
Rhizarthrosis is a big word for a specific kind of arthritis. It affects the base of the thumb where it meets the wrist. This joint is called the basal joint.
When this joint wears down, it can cause sharp pain every time you pinch, grip, or twist. Opening jars, turning keys, or even writing can become hard. Many people feel frustrated because their thumb does not work like it used to.
You may be wondering why this matters. The thumb is different from other fingers. It moves in special ways that let you grasp and pinch. When the basal joint is damaged, you lose that ability.
What Makes This Surgical Approach Different?
Researchers tried a brand new idea. Instead of removing bones or fusing joints, they rotated the joint area. Think of turning a puzzle piece to fit better.
Research shows that this surgery switched two joints at the base of the thumb. One joint is called the trapezio metacarpal joint. The other is called the trapezoid metacarpal joint. By rotating these joints 180 degrees, the surgeons gave patients a fresh joint surface to use.
Here is where it gets interesting. The surgeons did not just spin the bones around. They kept the ligaments and blood vessels attached. Ligaments are like strong rubber bands that hold bones together. Blood vessels carry blood that keeps bones alive and healthy.
The blood supply came from the dorsal branch of the radial artery. That is a blood vessel on the back of your wrist near the thumb side. By carefully protecting this vessel, the surgeons made sure the bones would heal.
How Does the Rotation Surgery Work?
Let us look closer at what happened during the operation. The surgeons made a cut on the back and side of the wrist. This is called a dorso radial approach. It gave them a clear view of the thumb bones and joints.
Next, they carefully separated the blood vessel from the surrounding tissue. This step is called arteriolysis. It allowed them to move the vessel safely without cutting it.
Then the surgeons made cuts in two bones. These are the first and second metacarpal bones. Metacarpal bones are the long bones in your hand that connect to your fingers and thumb. The cuts were made near the end of the bones, in an area called the metaphysis.
After that, they opened the capsule all around the joints. The capsule is like a bag that surrounds each joint. Once it was open, they could move the joint complex.
The surgeons rotated the whole joint complex 180 degrees while keeping the blood vessel attached. They stabilized everything with thin metal wires called Kirschner wires. These wires hold the bones in place while they heal.
Finally, they rebuilt the capsule and ligaments, then put the hand in a plaster cast to keep it still.
What Happened After Surgery?
Patients wore the cast for several weeks. Four weeks after surgery, they could start moving their thumb on their own. At six weeks, they began hand therapy with a therapist who helped them regain strength and motion.
Doctors checked on the patients at two, four, and six weeks. They took X rays to see how the bones were healing. At three months, they used a special imaging test called tomography to get a closer look.
What Happened to the Eight Patients?
Studies indicate that all eight patients had positive outcomes. Three patients had good results. Five patients had excellent results. That means most people got very good relief from their pain.
According to this study, every patient regained complete motion of the thumb. They could move it in all directions just like before the arthritis. The first metacarpal bone, which is the thumb bone, became stable again. This means it did not wobble or collapse.
Most importantly, all patients restored their pinch strength without pain. Pinch strength is the force you use when you squeeze your thumb and finger together. This is essential for daily tasks like buttoning shirts, holding a pen, or picking up small objects.
The trapezoid metacarpal joint took over the job of the old worn out joint. It provided pain relief, mobility, and stability. The bone chain of the thumb was restored, which means the bones lined up properly again.
| Outcome | Number of Patients |
|---|---|
| Good Results | 3 |
| Excellent Results | 5 |
| Total Patients | 8 |
Frequently Asked Questions
How long does recovery take after this surgery?
According to research published in Chir Main (2000), patients begin active thumb movement at four weeks after surgery. Hand therapy starts at six weeks. Full assessment of results happens at three months with detailed imaging.
Does this surgery work for everyone with thumb arthritis?
This study looked at patients with severe rhizarthrosis, which means very advanced arthritis that destroyed the thumb joint. The surgery was designed for cases where other treatments may not work well. Only your doctor can tell if this approach is right for you.
Will I be able to use my thumb normally after this surgery?
Studies indicate that all eight patients in this research regained complete thumb motion and painless pinch strength. This means they could move their thumb freely and use it for daily tasks without pain.
What makes this surgery different from other thumb arthritis surgeries?
Research shows that this technique rotates the joints instead of removing or fusing them. The surgeons keep the blood supply and ligaments intact, which helps the bones heal and stay stable. The trapezoid metacarpal joint takes over the work of the damaged joint.
Conclusion
If you are living with severe thumb arthritis, you deserve to know all your options. This study shows that rotating the thumb joints while keeping blood vessels alive can restore motion, strength, and pain relief. Eight patients experienced positive results, with most achieving excellent outcomes.
While this is a specialized surgery, it offers hope for people whose thumb pain has not improved with other treatments. Talk to your doctor about what might work best for you. Every person is different, and your care team can help you choose the right path.
Remember, you are not alone in this journey. Many people struggle with thumb arthritis, and researchers continue to look for better ways to help.
