If you’ve been living with thumb pain because of arthritis, you might wonder if surgery could help you. This article talks about a study on thumb joint replacements using the Ivory(R) prosthesis. The focus is on how this treatment can improve pain levels, movement, and quality of life.
Here are three key points from the study:
- The prosthesis helped reduce pain significantly.
- Thumb movement improved after the surgery.
- The implant showed excellent durability in most patients.

What is this study about?
Thumb pain is often caused by arthritis, also known as “rhizarthrosis.” Arthritis happens when the cartilage, a cushion inside your joints, wears down, leading to bone-on-bone rubbing. Ouch!
This study focuses on people with arthritis in the base joint of their thumb, called the trapeziometacarpal joint. The researchers looked at how a specific implant, the Ivory(R) prosthesis, helped patients after their thumb joint replacement surgery.
What were the study results?
The study included 40 patients who had 48 thumb joint replacements. Most patients were women aged 41–75 years. Let’s break down the findings:
Did pain go away?
Yes, for most people! Before surgery, patients rated their pain levels at a high 3.46 out of 4. Three years after surgery, this dropped to just 1.44. Imagine the relief.
Did thumb movement improve?
Thumb movement definitely improved. Before surgery, patients could score 8.57 out of 10 on thumb opposition tests. This test shows how well you can move your thumb to touch other fingers. After surgery, the score jumped to 9.85 out of 10.
| Measurement | Before Surgery | After Surgery |
|---|---|---|
| Pain Level (0–4 scale) | 3.46 | 1.44 |
| Thumb Movement Score (0–10 scale) | 8.57 | 9.85 |
Did the implant last long?
Yes, it performed well. After three years, 97.9% of the implants were still holding up without major problems. Only one implant had loosening, and three implants needed adjustments because they slipped out of place—a bit like a loose puzzle piece.
Any complications?
About 10% of patients developed a condition called De Quervain’s tenosynovitis, which causes wrist pain linked to tendon irritation. Interestingly, the study did not find this to be directly caused by thumb length changes after surgery.
FAQs
What is the Ivory(R) prosthesis?
It is an artificial joint made to replace an arthritic thumb joint. It’s like giving your thumb a new, pain-free connection!
Is this surgery only for severe arthritis?
Yes, it’s meant for advanced arthritis that cannot be fixed with simpler treatments.
Do most people feel better after this surgery?
Yes, most patients report less pain and better thumb movement.
Conclusion
This study shows that using the Ivory(R) prosthesis for thumb joint replacement has great short-term success. Pain decreases, movement improves, and most implants last well for at least three years.
