Distal radius fracture is a common injury, and open reduction with internal fixation, such as volar plate fixation, is often employed to achieve stable fixation and allow early mobilization [1]. However, complications can occur following this procedure, including extensor tendon tear, which can lead to significant morbidity and impaired function [2]. While clinical symptoms and plain radiography have traditionally been used to diagnose these complications, ultrasound imaging has emerged as a useful tool for early detection and management [3]. In this case report, we describe a patient with extensor tendon tear following volar plate fixation of a distal radius fracture, diagnosed preoperatively on ultrasound. By highlighting the benefits of ultrasound in detecting this complication, we hope to contribute to the literature and improve patient outcomes.
