M65.3

Clinical Causes: Repeated gripping or use of the fingers that overworks the tendons Inflammation due to conditions like rheumatoid arthritis or diabetes Age-related degenerative changes affecting tendon flexibility Injury or trauma to the fingers or hand Anatomic variations influencing tendon movement Certain activities or occupations involving repetitive finger movements

Key Symptoms: A catching or popping sensation when moving the affected finger Finger stiffness, especially in the morning Tenderness and soreness at the base of the affected finger A palpable nodule along the tendon sheath Progressive difficulty in straightening or bending the finger In severe cases, the finger may become stuck in a bent or extended position

Diagnosis Path: Diagnosis is primarily based on a clinical examination, where a healthcare provider observes the finger's movement and palpates for nodules or swelling. Imaging tests like ultrasound can confirm the presence of nodular thickening of the tendons and rule out other conditions, but often the diagnosis relies on physical findings and patient history. The characteristic catching sensation during finger movement further supports the diagnosis of trigger finger.

Treatment Protocols: Management options aim to relieve symptoms and restore normal finger movement. These include: - Non-surgical interventions: - Rest and activity modification to reduce tendon stress - Use of splints or braces to immobilize the finger - Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce inflammation - Corticosteroid injections into the tendon sheath to alleviate swelling - Surgical options: - Trigger finger release surgery, which involves cutting the constricted part of the tendon sheath to free the tendon - Postoperative therapy may include hand therapy exercises Early treatment can help prevent the progression to a permanently locked finger, and the choice of intervention depends on the severity and response to initial therapies.
