You are working in the treatment area with a medical student and she is ready to review a “straightforward” case with you. She presents a young, healthy 27-year-old man with a laceration over the dorsal surface of the left hand after a kitchen mishap. It appears clean, and she doesn’t suspect a foreign body. The neurovascular status seems okay with the intact ability to extend the fingers. Her plan is to repair the wound and send the patient for follow up in 7 to 10 days with his family physician for suture removal. The wound appears superficial, but you are an astute clinician and wonder if the skin laceration might not be the only injury. Is there an associated extensor tendon injury?
