Abstract

Femoroacetabular impingement is uncommonly associated with a large rim fragment of bone along the superolateral acetabulum. We report an unusual case of femoroacetabular impingement (FAI) with chronic acetabular rim fracture. Radiographic, 3D computed tomography, 3D magnetic resonance imaging and arthroscopy correlation is presented with discussion of relative advantages and disadvantages of various modalities in the context of FAI.

Keywords: 3D computed tomography, 3D magnetic resonance imaging, Femoroacetabular impingement, Rim fracture

Core tip: Rim fracture is an uncommon finding in the context of femoroacetabular impingement and its management can be aided by bony remodeling and labral-cartilage assessment on pre-operative 3D computed tomography and 3D magnetic resonance imaging.
