OBJECTIVE: The purpose of this article was to report our experience using ultrasound to assess digital nerve integrity after penetrating hand trauma with sensory deficit. Ultrasound was performed in the long axis on 22 digital nerves in 11 patients using a 12-14-MHz linear array hockey stick transducer. CONCLUSION: Of 22 volar digital nerves evaluated by sonography, six were transected. All imaging findings were confirmed surgically. High-frequency ultrasound permits accurate imaging of intact and transected volar digital nerves.
