Electric Shock Causes Rare Finger Tendon Rupture: A Unique Case Study

What is it about?

This article presents a case report on a 36-year-old man who experienced a complete rupture of the extensor digitorum communis tendon in his right middle finger following an electrical injury, a rare occurrence for this type of trauma. The patient initially presented with pain and swelling after receiving an electric shock while using a public fast charger, leading to a delayed diagnosis confirmed by ultrasound imaging. The methodology involved surgical intervention with a primary repair using the 4-strand Adelaide technique, followed by a specific hand rehabilitation program. The scope of the case highlights the unusual mechanism of injury, as tendon ruptures in the hand are typically associated with trauma or overuse, rather than electrical injuries. The main finding underscores the need for healthcare professionals to consider tendon ruptures as a potential outcome of electrical injuries and the importance of timely diagnosis and repair. The article also discusses differential diagnoses considered and ruled out during the investigation and treatment process. This case contributes new insights into the spectrum of injuries that can result from electrical shocks, specifically in the context of tendon damage.

Why is it important?

This research highlights a rare case of extensor digitorum communis tendon rupture in the finger following an electrical injury, a previously undocumented occurrence. The study underscores the importance of considering tendon injuries in patients presenting after electrical shocks, expanding the understanding of potential complications from electrical injuries. This can inform clinical practice by encouraging healthcare professionals to include tendon rupture in differential diagnoses when dealing with similar cases. Key Takeaways: 1. The study presents the first documented case of an extensor tendon rupture in a finger caused by an electrical injury, expanding the spectrum of musculoskeletal injuries resulting from electrical shocks. 2. It emphasizes the necessity for swift diagnosis and immediate primary repair of tendon injuries following electrical injuries to prevent long-term functional impairment. 3. The research highlights the successful use of the 4-strand Adelaide technique for primary tendon repair and the importance of tailored rehabilitation programs in achieving favorable patient outcomes.
