As you’ve just heard in the video, trigger thumb is a common and debilitating condition. The tendons in your thumb and fingers are covered in a tunnel like structure of tissues that are called sheaths. If you have trigger thumb, your tendons have become inflamed. Because of this inflammation or swelling, your tendons are no longer properly gliding through your sheaths. When this happens, the base of your fingers may lock up, click, or pop. Essentially, your fingers get stuck in a non relaxed position. This has the potential to be a very painful and frustrating condition, as you lose the full function of your thumbs. This condition can happen to all of your fingers including your thumbs, index, middle, ring, and pinky.
Tip 5: Punctuation can enhance your search as well. Use quotes ("search term") to only include pages with the same words in the same order. But only use this if you are looking for an exact word or phrase, otherwise you may exclude helpful results. Add an asterisk (search term*) as a placeholder for any unknown or wildcard terms. For example, C*l Tunnel would give you results for Cubital Tunnel and Carpal Tunnel. Place a question mark (search term?) for single-character wildcard matching. For example, pa?ent would give you results for parent, patent, etc. You may also use the plus sign (search + word) between words for words you must have in the results.
If conservative treatment options fail to resolve the condition and symptoms persist for 6 months or more and your quality of life is adversely affected, your surgeon may recommend you undergo a percutaneous trigger finger release surgical procedure to release the tendon. This surgery is usually performed in an operating room under local or regional anaesthesia on an outpatient basis as day surgery. Your surgeon makes one small incision, about inch long, to the affected finger area. The surgeon then releases the tight portion of the flexor tendon sheath. The incision is then closed with a couple sutures and covered with a sterile dressing.
