Coccydynia is pain in and around the coccyx, with trauma being the most common etiologic factor. The authors describe the case of a 60-year-old woman who was injured in an automobile accident several months before consultation. After the physician recorded the patient's history, performed a physical examination, and reviewed imaging reports, lumbar radiculopathy and somatic dysfunction of the lumbar and sacral vertebrae were diagnosed as the cause of her coccydynia. During a 6-week period, the patient underwent a series of 3 epidural steroid injections, osteopathic mobilization of the lumbar and sacral spine, and manual manipulation of the coccyx with anesthesia. After each treatment session, the patient reported a substantial improvement in radicular pain as well as a subjective increase in her lower extremity range of motion.
