We present the case of a 39-year-old man who reported to the primary care physician for low back pain. Pain persisted despite extensive assessment and therapy. During the course, bilateral femoral neck fractures occurred and due to multiple enrichments in scintigraphy chronic multifocal (sterile) osteomyelitis was suspected. In the further follow-up the appropriate diagnosis of osteomalacia was established in bone biopsy and adequate treatment with Vitamin D was initiated. During therapy, the patient was free of pain or discomfort.
