## Overview Gluteal atrophy is loss of muscle mass in the hindquarter secondary to chronic disuse from hind-limb lameness or neurologic disease. Viewed from behind, the affected side appears smaller. It is a sign of prolonged reduced use rather than a primary disease. ## What It Indicates Chronic pain or neurologic dysfunction in the ipsilateral hind limb leading to disuse. ## Diagnosis Visual asymmetry plus identification of the underlying lameness or neurologic deficit. ## Treatment Treat the primary cause. Controlled exercise and physiotherapy help restore muscle once the horse is comfortable. ## Recovery and Prognosis Muscle can rebuild if the underlying problem is resolved. Long-standing atrophy recovers slowly. ## Prevention Early treatment of hind-limb lameness.
