Treatment of Patients With Electrical Injury by Using Modified Forearm Venous Flap: Retrospective Case Series Study.

Objective: Severe hand electrical injuries often occur in functional areas such as joints; the repair requires attention to both appearance and function due to the visibility of the hand. This study aimed to present the clinical experience of successfully repairing hand electrical injuries using improved forearm venous flaps.

Methods: From 2020 to 2022, 15 cases of severe hand electrical injuries were diagnosed, including 10 males and 5 females. Among them, 6 cases were repaired in the first web space, 4 in the thumb, 3 in the index finger, 2 in the middle finger, 2 in the ring finger, and 2 in the little finger. The size of venous flaps ranged from 2.0 cm × 1.8 cm to 12 cm × 4.0 cm. All patients underwent repair using improved forearm venous flaps. The follow-up period ranged from 5 to 8 months.

Results: All flaps survived without serious complications. All patients were satisfied with the postoperative aesthetics and function of their hands.

Conclusion: The improved forearm venous flap is a simple and reliable method for repairing hand electrical injuries.
