Educational video describing the condition known as Trigger Thumb.
Stenosing tenosynovitis of the thumb, often referred to as trigger thumb, is one of the more common abnormalities of the hand. This condition is associated with painful triggering or locking of the thumb.
When the patient tries to straighten the thumb, the nodule jams beneath the pulley proximally. This occurs with a painful snap much like a trigger being pulled and released, with either flexion or extension of the thumb.
Small changes in the tendon’s diameter will have significant effect on the function of the thumb. The nodule is usually pulled proximally to the pulley with active thumb flexion.
Treatment
Anti-inflammatory medication.
Injection
•Inject into the sheath, not the tendon.
•Put the needle obliquely towards the tendon
•Withdraw the needle slightly and inject freely into the sheath.
•Ultrasound-guided injection of the tendon sheath and pulley may be of benefit.
•The needle is inserted into the sheath above the tendon and fluid is injected.
•If symptoms persist, consider surgery. Release the pulley to allow active motion without triggering. Note the position of the radial digital nerve close to the incision.
