Anatomy Chiropractic is a San Diego Upper Cervical Chiropractic clinic that also treats the full spine. The upper cervical region of the spine consists of the top two bones of the spine, C1 and C2 (aka Atlas and Axis). Upper cervical chiropractors specialize in creating alignment between C1, C2, the head, and the rest of the spine. At Anatomy, we specialize in Atlas Orthogonal Chiropractic, a type of upper cervical chiropractic.
