M65.342
Trigger finger, left ring finger
Clinical Classification Guidelines
Medical Intelligence & Overview
Trigger finger, medically known as stenosing tenosynovitis, is a condition that causes difficulty in moving the affected finger smoothly. When you have trigger finger, the finger (in this case, the left ring finger) may catch, lock, or pop when you bend or straighten it. This condition can interfere with everyday activities and, if left untreated, may lead to persistent discomfort and limited finger mobility.
Causes & Symptoms
Clinical Causes: Repetitive gripping or grasping motions over time Inflammation of the tendons within the finger due to overuse Finger injuries or trauma that cause swelling and thickening of the tendon sheath Certain medical conditions such as rheumatoid arthritis, diabetes, or gout that can increase the risk Age-related changes leading to thickening or narrowing of the tendon sheath
Key Symptoms: A popping or clicking sensation when moving the finger Tenderness or stiffness at the base of the affected finger, especially in the morning A finger that catches or locks in a bent position, occasionally requiring manual assistance to straighten Swelling or thickening of the tendon sheath over the affected finger Pain or discomfort when moving the finger
Diagnostic & Treatment
Diagnosis Path: Diagnosis is primarily based on a physical examination by a healthcare provider, who will assess the finger’s range of motion, check for swelling or nodules, and observe any catching or locking movements. In some cases, imaging studies like ultrasound or MRI may be employed to visualize the tendons and rule out other conditions.
Treatment Protocols: Rest and activity modification to avoid aggravating movements Application of ice packs to reduce swelling Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief Splinting or finger immobilization to limit movement and allow healing Physical therapy and hand exercises to improve flexibility and strength Corticosteroid injections to decrease inflammation within the tendon sheath Surgical intervention (trigger finger release) in cases where conservative treatments fail, involving releasing the constricted portion of the tendon sheath
