Trigger Finger & Trigger Thumb
Ask anyone who has experienced the symptoms of stenosing tenosynovitis, and they will tell you just how uncomfortable and debilitating it can be. In fact, it is one of the most common causes of hand pain and and limited hand motion range. This condition, commonly called ‘trigger finger’ is caused by swelling along the tendon in the palm of hand, and outward towards the finger. This particular tendon goes through several tunnels (pulleys) on its way toward the finger, which help maintain its position and proper functioning. Localized swelling along the tendon causes inflammation near the first tunnel (A1 pulley) and can lead to changes within the tunnel, reducing the size and causing scar tissue to develop, and so the finger can be locked in a bent position. Below is a guide written by top Phoenix hand surgeon, Dr. Michael Fitzmaurice, to explain some of the trigger finger and trigger thumb symptoms and treatment options.
Locked Finger Symptoms
Symptoms can include pain in the fingers associated with activity, popping or snapping sensation with activity, and even locking up with an inability to straighten fingers. Conditions such as diabetes and rheumatoid arthritis can cause increased swelling around the tendon and subsequently lead to occurrence of trigger finger. People who perform repetitive activity or forceful gripping are also more susceptible to this locked finger condition, however, in some cases no specific cause is identified.
Trigger Thumb is a painful condition of the thumb caused by either a narrowing of the tunnel that supports the tendon which flexes the thumb, or an increased inflammation of the tendon. The first symptoms are usually soreness at the base of the thumb. Painful clicking or snapping often occurs, and some patients notice the joint gets locked in position and cannot straighten. Conditions such as diabetes and rheumatoid arthritis in Nevada can cause increased swelling around the tendon and subsequently result in trigger thumb. People who perform repetitive activity or forceful gripping are also more susceptible. However, in some cases there is no specific cause identified.
Treatments for Stuck Fingers
For some people, local steroid injection has been shown to help in early forms of treatments for trigger finger. However, most patients are not content to spend many weeks being treated with conservative measures, only to have the locked fingers symptoms persist. Fortunately, a technique performed here in Phoenix, Arizona can effectively treat stenosing tenosynovitis using the EndoTech® Endoscopic System.
