If you have thumb pain or a condition called rhizarthrosis, you might feel frustrated or stuck. But there could be a solution that helps your thumb move better and eases your discomfort. A study published in 2023 looked at the short-term results of an advanced prosthesis called the Touch® thumb joint implant. Let’s break down what it found.
Key points from the study:
- The prosthesis helped most participants regain mobility in their thumb.
- Many experienced less pain after surgery.
- No major complications like infections or dislocations were reported.

What can this study tell us?
This study followed 48 patients who had severe thumb joint pain because of rhizarthrosis. Rhizarthrosis is a kind of arthritis at the base of the thumb where it meets the wrist. It usually happens when the cartilage in that joint wears away, causing pain and stiffness.
Why this matters: when medicines and therapy do not help, surgery like joint replacements might be needed. This research looks at how well a new prosthesis called Touch® works for people who need thumb joint surgery.
How does the Touch® thumb prosthesis work?
The Touch® prosthesis replaces the worn out thumb joint. Its design is called “dual mobility,” which means it has two moving parts that help reduce the chance of dislocation, when the joint pops out of place. You may wonder why this matters, it lets the thumb move better while staying stable.
The study included adults with an average age of 62 who had this surgery because their arthritis was too advanced to treat with non-surgical methods.
Study results at a glance
After two years, most people who had a Touch® thumb joint prosthesis were happy with it. Let us look closer at the findings:
| Outcome | Details |
|---|---|
| Overall Satisfaction | 91.1% (51 patients) |
| Pain Reduction | From 4.45 before surgery to 1.2 after 2 years |
| Improved Mobility | Marked improvement in thumb movement |
| Complications | No infections or dislocations |
The study measured pain and function with the DASH questionnaire. This tool asks questions about how pain and weakness affect daily tasks. After surgery, DASH scores dropped a lot, meaning less pain and better function.
FAQ
- What is rhizarthrosis?
An arthritis at the base of the thumb that causes pain and stiffness due to worn cartilage. - Who can benefit from this prosthesis?
People with advanced arthritis in the base of the thumb who have not improved with therapy or medicines. - Will surgery guarantee pain relief?
Most patients had much less pain, but a few still felt mild discomfort during exercise or moving. - Are there risks involved?
This study did not report major problems like infections or joint dislocations.
Conclusion
The Touch® prosthesis shows promising results for people who need thumb joint replacements. It reduces pain, improves mobility, and has a good safety profile after two years. If you are exploring surgical options to treat thumb arthritis, this study suggests you should discuss it with your doctor.
