Buttock pain is a common complaint of patients in the pain clinic. However, assessment of fractures can be difficult if there is no trauma history. A 65-year-old woman with rheumatoid arthritis complained of bilateral pains in the buttocks for a month. She didn’t have a history of falls or other traumas and no fracture line was visible in plain lumbar X-rays. Although the patient had taken analgesics for two weeks, her pain persisted even with newly developed severe pain in the left groin. Magnetic resonance imaging of the pelvis revealed fragility fractures of the left parasymphyseal area and bilateral sacral ala. In addition, previously unrecognized osteoporosis was detected. Fragility fracture of the pelvis are rare, but we recommend that clinicians may consider these problems when an elderly patient complains of the motion-related sacrum or groin pain.
