## Overview Atlas pain refers to discomfort localized to the first cervical vertebra or its articulations with the skull (atlanto-occipital joint) and axis. It is a clinical sign rather than a specific diagnosis and may result from osteoarthritis, trauma, muscle strain of the poll region, or referred pain. Affected horses often show resistance to poll flexion, head shaking, or reduced performance under saddle. ## Causes Primary causes include osteoarthritis of the atlanto-occipital joint, previous fracture or subluxation, direct trauma, and insertional strain of the rectus capitis or obliquus capitis muscles. Secondary (referred) pain from dental disease, temporomandibular joint problems, or forelimb lameness can also manifest as apparent atlas-region discomfort. ## Diagnosis Palpation of the poll and atlas wings, assessment of range of motion, and observation under saddle are initial steps. Diagnostic analgesia of the atlanto-occipital joint, radiography, and ultrasound help localize the source. Nuclear scintigraphy may identify active bone remodeling. ## Treatment Treatment is directed at the underlying cause. Joint injection, anti-inflammatory medication, physiotherapy, and chiropractic or osteopathic techniques are used for osteoarthritis or soft-tissue pain. Rest and rehabilitation address acute strain. ## Recovery and Prognosis Prognosis depends on the primary lesion. Many horses with mild osteoarthritis or muscle pain improve with targeted therapy and return to full work. Advanced joint disease may limit long-term performance. ## Prevention Proper warm-up, appropriate bit and bridle fit, and prompt attention to dental or forelimb issues reduce secondary poll pain.
