Stenosing Tenosynovitis

Trigger Finger

Trigger finger, medically known as stenosing tenosynovitis, is a condition where a finger or thumb catches or locks in a bent position and then suddenly straightens with a snap. It occurs when the flexor tendon becomes irritated or thickened and cannot glide smoothly through its sheath. This leads to pain, stiffness, and a clicking or popping sensation, usually felt at the base of the affected finger. Symptoms are often worse in the morning or after rest. In more severe cases, the finger may become locked in a bent position and require manual extension.

# Treatment Summary for Stenosing Tenosynovitis Splinting is the recommended first-line therapy for mild to moderate cases, with nighttime use often showing symptom improvement within weeks. Corticosteroid injection is an effective minimally invasive option when splinting or physical therapy fails, offering fast relief by reducing inflammation at the A1 pulley. Physical therapy serves as a good next step if splinting doesn't work, focusing on stretching and strengthening to improve tendon glide, though recovery is gradual. Surgical release is highly effective for cases where other therapies have failed, providing definitive relief when conservative treatments are unsuccessful.
