RESUMO
Open reduction with internal fixation is a common approach for treating distal radius fractures. However, complications such as extensor tendon rupture can occur following this procedure. In this case report, we present a patient who experienced extensor tendon rupture following volar plate fixation of a distal radius fracture. The rupture was diagnosed preoperatively using ultrasound. We highlight the potential usefulness of ultrasound as a convenient and sensitive tool for diagnosing tendon injuries in patients with suspected complications following internal fixation of distal radius fractures. Furthermore, we discuss how ultrasound images can aid in localizing the site of tendon rupture and guide surgical incisions for smaller postoperative wound care, resulting in improved cosmetic outcomes.
