Osteomyelitis is an infection of bone, which most frequently is found in weight-bearing bones of lower extremities. Only 4% of acute osteomyelitis cases have been found in the pubic bones in Finland. These cases of the pubic bones are usually related to gynecological or urological procedures or trauma. Osteitis, which is much more common than osteomyelitis, is a differential diagnosis for pregnant or postpartum women. These two diseases are difficult to distinguish based on the symptoms, even if it is important because osteomyelitis needs to be cured with antibiotics but to cure osteomyelitis NSAIDs are enough. The diagnosis of osteomyelitis is based on clinical examination, radiological imaging and laboratory tests.
