Thumb pain can be frustrating and confusing. If you’ve been struggling with thumb pain after a recent injury, this article is for you. Today, we’re diving into a study that looks at how fixing ligaments in your thumb’s joint early can make a big difference.
Here’s what the research found:
- Thumb injuries can cause instability, making your thumb feel weak or wobbly.

What causes thumb pain?
Thumb pain often starts in the carpometacarpal joint, a spot where your thumb connects to your wrist. This joint helps your thumb move in many directions. Its stability comes mainly from strong bands of tissue called ligaments, which hold the bones tightly together.
You may be wondering what happens when a ligament gets hurt. Injuries to these ligaments can occur during sports, especially ball games or contact sports. Too much bending, twisting, or pressure on your thumb can cause these ligaments to tear, leaving your thumb feeling unstable. Over time, this instability can lead to rhizarthrosis, a painful problem where the joint wears out and gets stiff.
How do surgical repairs help?
Here is where it gets interesting. If the injury is caught early, doctors can repair the torn ligament through a surgery called ligament plasty. This helps restore the joint’s stability and prevents long-term problems.
What are the types of thumb sprains?
The study splits thumb injuries into three main types:
- Radial sprains: These happen when the thumb is pulled out to the side too hard, damaging an important ligament called the ulnar ligament. Doctors repair this with a tendon from your flexor carpi radialis. This tendon helps you bend your wrist, but surgeons can move it to support the ligament.
- Ulnar sprains: These occur from pushing the thumb backward too far, damaging the ligament on the other side. Here, doctors use a tendon called the abductor pollicis longus, the part that helps lift your thumb up.
- Axial compression injuries: These sprains come from pressing the thumb downward too hard. This type of injury affects several ligaments. Doctors repair it with a combined approach using tendons like the extensor carpi radialis brevis (a tendon that straightens your hand) and abductor pollicis longus.
Each type of injury gets a specific treatment method shown to improve stability.
The study findings
Now, let’s look closer. The study reviewed 10 cases of ligament repairs on patients who had recent thumb sprains from sports injuries. The surgeries helped stabilize the joint and prevented further damage. If left untreated, these injuries often lead to thumb weakness and rhizarthrosis down the road.
Here’s why acting early can make a difference: repairing the ligament as soon as possible prevents extra wear and tear on your joint. That means less pain and more freedom to use your hands as you normally would.
FAQ
- Why does my thumb feel like it might “give out”?
- That loose feeling could mean your thumb joint is unstable due to an injured ligament. A doctor might need to check for sprains.
- What happens if I ignore thumb pain after an injury?
- Untreated injuries can lead to long-term issues like rhizarthrosis (thumb arthritis), causing pain and stiffness in the joint.
- Does fixing the ligament mean surgery?
- Yes, ligament repair involves surgery. If you treat the injury early, the operation is simpler and can prevent future problems.
- Can thumb ligament injuries heal on their own?
- Some minor injuries may heal with rest, but major tears often need surgical repair to fully recover.
Conclusion
Thumb injuries can feel overwhelming, but early treatment makes a big difference. If your thumb feels unstable or painful after an impact or sudden movement, talk to your doctor. You don’t want to leave these injuries untreated.
