Atlanto-Axial and Atlanto-Occipital Joints Injection in the Treatment of Headaches and Neck Pain
Cervicogenic headache is referred pain from cervical structures innervated by the upper three cervical spinal nerves. The lateral atlanto-axial joint, which is innervated by the C2 ventral ramus, is a fairly common cause of cervicogenic headache. It may account for 16 % of patients with occipital headache.1 In human volunteers, distending the lateral atlanto-axial joint with contrast agent produces occipital pain, and injection of local anaesthetic into the joint relieves the headache.
