Closed digital arterial injury is rare. A seven-year-old boy sustained a crush injury to his right middle finger, resulting in a proximal phalanx-neck fracture displaced to the dorsal side. On presentation, his finger was warm and normal in color. Initially, closed reduction and percutaneous pinning were performed. However, the middle finger vascularization diminished, and the finger became cyanosed three hours after the operation. At this point, the patient was transferred to our hospital. Color Doppler ultrasonography showed interruption of bilateral digital arterial flow. Bilateral digital arterial reconstruction with vein grafting was performed immediately to preserve the middle finger. Finger vascularization was then re-established. Six months postoperatively, the middle finger was functional, and its appearance was almost restored to its pre-injury state.
Zigzag incision (A). The ulnar and radial digital arteries were crushed and ruptured. The black arrows indicate the distal and proximal ends of the ruptured arteries. Thrombosis was recognized on a digital artery (yellow dotted circle) (B and C). Vein grafting was performed (black double arrows) (D and E). The color of the middle finger improved at the end of surgery (F).
