title: [Notches of the acetabulum roof. Incidence: anatomoradiological correlation].
abstract: An unselected group of patients with rheumatoid affections presents radiologic evidence of a notch of acetabulum roof in about 20% of cases. The anatomic substratum of this variant is described and should be recognized to avoid a mistaken diagnosis of periarticular lacuna.
