If you have pain in your thumb or been told you might have rhizarthrosis, you are not alone. Rhizarthrosis is a kind of osteoarthritis that affects the thumb. But what does that mean, and why does it happen?
The article by Mas Garriga (2014) explains osteoarthritis. It tells what it is, what causes it, how it is classified, and how it shows itself. Here are some key points:
- Osteoarthritis is mainly caused by imbalances in how your joint tissues repair themselves.
- Rhizarthrosis is one common form of thumb osteoarthritis, often linked to age and other risk factors.
- Risk factors include natural ones like age and genetics, and things you can change, like weight.

What is rhizarthrosis, really?
Rhizarthrosis is a form of osteoarthritis. Osteoarthritis is a disease where joints wear down. It happens because of imbalances between how cells build up and break down cartilage. Cartilage is the firm and flexible tissue that protects the ends of bones where they meet in a joint.
In rhizarthrosis, this wear affects the base of your thumb and the joint that lets it move. Symptoms often include pain, stiffness, and trouble gripping or holding things.
Why does this happen to our joints?
You might wonder why this happens. Here is the important part. Osteoarthritis happens because of mechanical (physical strain) and biological (body process) problems that affect your joints.
- Mechanical problems: These include wear and tear, strain, or too much load on the joints. For example, repeated stress on your thumb may raise the risk of rhizarthrosis.
- Biological problems: These are changes inside your body that happen with age, like slower cartilage repair or persistent inflammation. Your body also may grow extra bone tissue, which can make things worse.
Risk factors for osteoarthritis can be things you cannot change, like your age and genes, or things you can control, like losing extra weight to reduce joint strain.
What else should you know?
Let us look closer at rhizarthrosis compared to other forms of osteoarthritis:
| Type | Body Part Affected | Prevalence |
|---|---|---|
| Knee osteoarthritis | Knee joint | 10.2% |
| Hand osteoarthritis (includes rhizarthrosis) | Thumb and finger joints | 6.2% |
| Hip osteoarthritis | Hip joint | 3.5%–5.6% (in people aged 50+) |
Rhizarthrosis is different because it affects how you grip objects and can really affect your daily life.
FAQ
Q1: What causes thumb pain?
A: Thumb pain can be caused by rhizarthrosis, which is a type of osteoarthritis. This happens when the joint at the base of your thumb wears down over time, leading to pain and stiffness.
Q2: What can I do to prevent osteoarthritis?
A: You cannot change things like your age or genetics, but keeping a healthy weight and avoiding activities that cause repeated strain on your joints might help lower your risk.
Q3: At what age does rhizarthrosis typically develop?
A: It is more common in people aged 50 and older, but it can happen earlier if your thumb has been overused or injured.
Q4: Is there a cure for osteoarthritis?
A: Osteoarthritis is a long-term condition. While it cannot be cured, its symptoms can be managed through lifestyle changes, medications, and treatments your healthcare provider suggests.
Conclusion
Thumb pain or rhizarthrosis might feel like a small problem, but it is worth paying attention to it early. If these symptoms sound familiar, consider seeing a healthcare professional. Lifestyle changes, such as healthy weight management, can also reduce your risk of joint issues.
