Abstract:
Snapping sensations in fingers commonly lead to diagnoses of trigger finger, usually attributed to A1 pulley pathology. However, less common etiologies can present challenges in accurate diagnosis and management. Here, we present a 70-year-old woman with right middle finger snapping, initially diagnosed as trigger finger but unresponsive to corticosteroid injection at the A1 pulley. Physical examination revealed snapping during right third proximal interphalangeal joint flexion. Ultrasound imaging revealed the lateral band’s anomalous movement during flexion, confirming the diagnosis. Conservative management was chosen due to the patient’s preference and mild symptoms. This case highlights the importance of considering uncommon causes of finger snapping and underscores the value of ultrasound in diagnosis, contributing to enhanced clinical recognition and utility of ultrasound for such rare pathologies.
