<DIV>This landmark text is the most comprehensive book ever published on the vertebral subluxation complex. This textbook is the culmination of several years of detailed research and review of chiropractic and medical literature on the topic of the cervical spine, the occipito-atlanto-axial subluxation, and upper cervical chiropractic care. Written by an expert renowned for his lucid, well-illustrated explanations of complex issues related to subluxation-based care. Dr. Eriksen reviews the anatomy and kinematics of the upper cervical spine and explains how impaired biomechanics causes neurological dysfunction and physiological concomitants. This reference is not intended to be about chiropractic technique; rather, Upper Cervical Subluxation Complex provides the "why" as opposed to the "how" of upper cervical chiropractic care. </div>
