M65.322
Trigger finger, left index finger
Clinical Classification Guidelines
Medical Intelligence & Overview
Trigger finger, medically known as stenosing tenosynovitis, is a condition that affects the tendons in the finger, causing pain, stiffness, and a catching or locking sensation when bending or straightening the finger. When it impacts the left index finger, it specifically involves the tendons responsible for flexing that finger, limiting smooth movement and sometimes leading to discomfort or locking of the finger in a bent position. This condition is common among adults and can affect daily activities that require fine finger movements.
Causes & Symptoms
Clinical Causes: Repeated activities involving gripping or repetitive finger movements Inflammation of the flexor tendon or its sheath, often due to overuse Injury or trauma to the finger or palm Underlying health conditions such as rheumatoid arthritis or diabetes mellitus Aging leading to degeneration of the tendons Anatomical differences in the tendons or pulley system of the finger
Key Symptoms: Tenderness or a painful bump at the base of the affected finger A catching or locking sensation when moving the finger Stiffness, especially in the morning Difficulty fully straightening or bending the finger Swelling around the affected area Possible clicking sensation during finger movement
Diagnostic & Treatment
Diagnosis Path: Diagnosis of trigger finger typically involves a physical examination where the healthcare provider assesses finger movement, looks for tenderness or a nodule at the base of the finger, and checks for the characteristic catching or locking sensation. In some cases, imaging tests such as ultrasound or MRI may be performed to rule out other conditions and to evaluate the affected tendons and sheath.
Treatment Protocols: Rest and activity modification to avoid aggravated movements Use of splints to immobilize the finger and reduce inflammation Nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve pain and swelling Stretching and gentle exercises to improve flexibility Corticosteroid injections into the tendon sheath to reduce inflammation and swelling Surgical release of the pulley sheath if conservative treatment fails, which involves cutting the constricted part of the sheath to allow free tendon movement
