Why Does My Thumb Hurt and What Can Help It Get Better?

If your thumb hurts at the base and feels stiff or weak, you may have a condition called rhizarthrosis. This is a type of arthritis that affects the joint where your thumb meets your wrist. A new study in Science and Innovations in Medicine looks at different ways doctors can help people who have thumb pain from this condition. Let us walk through what this means for you.

Key Findings at a Glance

  • Rhizarthrosis is arthritis of the thumb joint where the thumb meets the wrist, and it mostly affects women after menopause.
  • This condition greatly reduces the strength and ability to grasp things with your hand.
  • Treatment options include non-surgical methods like splints and medicine, as well as several surgical choices.
  • Surgical treatments include ligament reconstruction, tendon interposition, joint removal, joint replacement, and arthrodesis (fusing the bones together).
  • A team approach using different types of treatment together often works best.

What is rhizarthrosis and who gets it?

According to this study, rhizarthrosis is an osteoarthritis of the trapezium-metacarpal joint. Let us break that down into simple words.

What is rhizarthrosis? Rhizarthrosis is when the cartilage in the joint at the base of your thumb wears away. The trapezium-metacarpal joint is the place where your thumb bone meets a small bone in your wrist called the trapezium. When this joint gets arthritis, it hurts and becomes stiff.

Research shows that this condition is common. It affects many people. The study explains that it mainly happens to women after menopause. Menopause is the time in a woman’s life when her monthly periods stop, usually around age 50.

You may be wondering why this matters. The reason is simple. This condition does not just cause pain. It changes your entire life. The study says it has a significant impact on quality of life and functionality of the hand.

Why does the thumb matter so much?

Here is where it gets interesting. Your thumb is not just another finger. According to this study, the thumb is critical for grasping and strength of the entire hand.

Think about everything you do with your hands. You pick up a cup. You button your shirt. You open a jar. You hold a pen. Your thumb works with your other fingers to make all of this possible.

Research shows that functional impairment of the thumb mobility in rhizarthrosis reduces hand function significantly. In simple words, when your thumb cannot move well because of this arthritis, your whole hand cannot work well.

This explains why even though this problem is just in one small joint, it can make daily tasks very hard.

What are the treatment options?

Let us look closer at what can help. The study notes that despite its high prevalence and risk of disability, therapeutic options for rhizarthrosis remain limited. Prevalence means how common something is. Therapeutic options are the different treatments available.

The good news is that there are still several ways to help. According to this study, treatment usually requires a multidisciplinary approach using a combination of non-pharmacological, pharmacological and surgical strategies.

What does multidisciplinary approach mean? This means that different types of doctors and health professionals work together to help you. They combine different kinds of treatments to get the best results.

The three main types of treatment are:

  • Non-pharmacological strategies: These are treatments that do not use medicine. They might include splints, exercises, or physical therapy.
  • Pharmacological strategies: These are treatments that use medicine to reduce pain and swelling.
  • Surgical strategies: These are operations that fix or change the joint when other treatments do not help enough.

What surgical choices are available?

When other treatments do not give enough relief, surgery may be an option. The study reviews various surgical treatment options for rhizarthrosis. Let us go through each one.

Ligament reconstruction

Research shows that ligament reconstruction is one surgical choice. A ligament is a strong band of tissue that connects bones together. In this surgery, doctors rebuild or repair the ligaments around your thumb joint to make it more stable.

Tendon interposition

Another option is tendon interposition. A tendon is a tough cord that connects muscle to bone. In this procedure, doctors place a piece of tendon between the bones in your thumb joint. This acts like a cushion to reduce pain and keep the bones from rubbing together.

Resection arthroplasty

Studies indicate that resection arthroplasty is also used. In this surgery, doctors remove part or all of the damaged bone in the joint. This takes away the source of pain.

Joint replacement

Joint replacement is another surgical option mentioned in the study. In this procedure, doctors remove the damaged joint and put in an artificial joint made of metal, plastic, or other materials.

Arthrodesis

Finally, arthrodesis is a choice. In this surgery, doctors fuse the bones of the joint together so they cannot move. This stops the pain but also stops movement in that joint.

Surgical Option What It Does
Ligament reconstruction Rebuilds the ligaments to stabilize the joint
Tendon interposition Places tendon tissue as a cushion between bones
Resection arthroplasty Removes damaged bone from the joint
Joint replacement Replaces the joint with an artificial one
Arthrodesis Fuses the bones together to stop movement and pain

Each of these surgeries has different benefits. Your doctor will help you decide which one might be right for you based on your specific situation.

Common questions about thumb pain

Who gets rhizarthrosis most often?
According to this study, rhizarthrosis mainly affects postmenopausal women. This means women who have gone through menopause are at higher risk for this type of thumb arthritis.

Can rhizarthrosis be treated without surgery?
Research shows that treatment usually requires a combination of approaches. Non-surgical treatments like splints and medicine are often tried first. Surgery is considered when these other treatments do not provide enough relief.

How does thumb arthritis affect daily life?
Studies indicate that rhizarthrosis has a significant impact on quality of life and hand functionality. Because the thumb is critical for grasping and hand strength, problems with the thumb joint reduce your ability to do everyday tasks.

What makes the thumb so important for hand function?
The thumb is critical for grasping and strength of the entire hand. When thumb mobility is impaired by rhizarthrosis, it reduces hand function significantly because the thumb works together with the other fingers for almost everything you do with your hands.

What to remember

If you have pain at the base of your thumb, you are not alone. Rhizarthrosis is a common condition that affects many people, especially women after menopause. The good news is that there are many treatment options available.

According to medical evidence, the best approach usually combines different types of treatment. This might include splints, medicine, and in some cases, surgery. There are several surgical options, each designed to help in a different way.

The most important step is to talk with your doctor. They can examine your thumb, understand your symptoms, and help you find the right treatment plan for your situation. Do not wait if your thumb pain is affecting your daily life. Help is available.
