Identify the flexor carpi ulnaris and the ulnar artery by having the patient deviate their hand in an ulnar direction at the wrist, giving a thumbs up. The flexor carpi ulnaris is the most medial, or ulnar, tendon. The ulnar artery can be palpated just medial and dorsal to the tendon. The nerve lies between the artery and the flexor carpi ulnaris.
Here, the flexor carpi ulnaris is clearly identified in blue and the approximate injection point in red. Insert the needle under the flexor carpi ulnaris 1 centimeter just palmar to the ulnar styloid. If blood is aspirated, withdraw the needle a few millimeters and aspirate again. The nerve is more superficial from the point of injection. Inject approximately 5 to 7 milliliters of anesthetic.
To block the cutaneous branch of the ulnar nerve, inject 3 to 5 milliliters of anesthetic just above the tendon of the flexor carpi ulnaris.
