title: Idiopathic protrusio acetabuli. A histological study.
abstract: Histological features of the acetabular floor in idiopathic protrusio acetabuli consist of replacement of the marrow spaces with active vascular fibrous granulation tissue and in some areas disruption of the trabecular pattern. This process could possibly elucidate the pathogenesis of protrusio.
