Using a Splint for Trigger Thumb Treatment: Why Does My Thumb Lock Up?

Is your thumb locking up, disrupting your daily tasks, and causing pain? The most common reason for uncontrollable thumb locking and clicking is trigger thumb. The irritating condition not only causes pain in your thumb but also makes getting through the day using your hands next to impossible. Keep reading to learn more about trigger thumb and how you can use this brace to help ease and treat the symptoms.

What is Trigger Thumb?

The first step to treating trigger thumb is to understand what exactly this condition is and what causes it.Trigger finger can affect any of the fingers, including the thumb. This condition occurs when the tendons leading from your wrist up through your fingers have become inflamed, causing them to no longer work properly. When your tendons become swollen or inflamed, it can cause your fingers to pop, click, and lock due to getting stuck in a state that is not relaxed.

Trigger Thumb Causes

Inflammation of the tendons resulting in trigger thumb is most often caused by overuse and repetitive motions. It’s likely your trigger thumb is caused by a job or hobby requiring you to make repetitive gripping or grabbing movements.

Symptoms of Trigger Thumb

Wondering if you have trigger thumb? Here are the most common trigger thumb symptoms associated with the condition:

  • Feeling stiffness in your thumb (especially first thing in the morning)
  • Tenderness at the base of your thumb
  • Thumb locked in a bent position that you are unable to straighten
  • Thumb catching or locking in a bent position and suddenly popping straight
  • Popping or clicking noise as you move your thumb

Trigger finger can affect any of the fingers, so you may experience these symptoms in more areas than your thumb alone. This brace is designed to help specifically with trigger thumb symptoms.

How Can I Treat My Trigger Thumb?

Treating trigger thumb will depend on the severity of the condition. If you are experiencing minor to moderate symptoms and pain, completing stretches and exercises along with using a thumb immobilizer brace such as this one can help decrease inflammation and restrict locking movements. For more severe cases of trigger thumb, trigger finger surgery may be necessary.  If you are looking for relief from severe trigger thumb pain, you should see your doctor or medical professional for the best treatment solution.

Tendonitis vs Carpal Tunnel: Which Condition Do I Have?

Carpal tunnel syndrome and tendonitis are common conditions that can affect the wrist and hand. The symptoms and causes can be similar, making it easy to confuse the two. However, there are a few differences that may impact the way you treat and find relief from the pain you are experiencing.

Thumb and Wrist Tendonitis

Tendonitis is caused by inflammation of tendons. When it comes to thumb tendonitis, this condition is referred to as De Quervain’s tenosynovitis. Thumb tendonitis results from inflammation around the base of the thumb, as well as the inside of the wrist and forearm. This pain will get worse the more you use your hand and thumb, causing pain or difficulty to move the thumb, especially when grabbing or pinching objects.

Carpal Tunnel in the Wrist and Thumb

CTS (carpal tunnel syndrome) gradually develops over time, sometimes leading to tingling, numbness, burning, and weakness in the hand and wrist. This pain is caused by increased pressure on the median nerve, causing it to compress. The nerve runs through the carpal tunnel, which controls and affects movement in the hand and all fingers, excluding the pinky. Oftentimes, you’ll find that this pain is much worse at night and will likely work its way from your wrist to your fingers and thumb.

Carpal tunnel and tendonitis are very common, as they both can cause pain and weaken your wrist and thumb. The main difference between the two conditions is that carpal tunnel syndrome is caused by nerve compression, while tendonitis is the result of inflammation and swelling.

Is This Thumb Spica Stabilizer Right for Me?

Whether you need some extra support throughout the day or comfortable immobilization at night, this thumb support brace can help protect and relieve pain. The neoprene wrist wrap is soft and comfy against the skin, yet thick enough to provide targeted compression where you need it. For anything from arthritis, to recovering from a broken thumb, this universal immobilizer is an easy, effective, and cost-efficient way to support your weakened wrist and thumb.
