6 weeks after undergoing an open carpal tunnel release operation, a 44-year-old woman comes to the physician because of new symptoms of numbness of her right hand. When she is asked about the exact location of these symptoms, she points to the area over the right thenar eminence. Percussion of the area between the flexor carpi radialis and palmaris longus tendons at the distal palmar wrist crease produces a painful shock-like sensation radiating into the affected area of the palm. An intraoperative nerve injury is suspected. Which of the following nerves is most likely injured in this patient?
A) Dorsal sensory branch of the ulnar nerve
B) Lateral cutaneous nerve of the forearm
C) Palmar cutaneous branch of the median nerve
D) Recurrent motor branch of the median nerve
E) Sensory branch of the radial nerve
