[Osteoid osteoma of the posterior edge of the acetabular bone of the hip simulating a lumbo-radicular syndrome: a clinical case].

The authors describe a clinic case regarding a 23 year-old man affected by an osteoid osteoma of the hip's posterior edge of the cotyloid cavity. The illness had been treated for two years as a lumbar disc syndrome. As any objective clinic sign missed at the hip's level and given the rarity of the location, only surgical removal was able to cure the patient.
