FAI

The surgical management of symptomatic femoroacetabular impingement (FAI) generally is indicated after the failure of a trial of nonsurgical treatment. Surgical planning includes an assessment of the labrochondral pathology as well as of the acetabular and proximal femoral bony deformity. Advanced articular cartilage disease generally is associated with poorer outcomes. Surgical hip dislocation and hip arthroscopy have been used, with favorable early outcomes and low complication rates. Careful patient selection is important in predicting the success of the surgical management of symptomatic FAI...

Imaging studies play a key role in establishing the diagnosis of femoroacetabular impingement (FAI). When clinical examination is suggestive of FAI, radiographic evidence should confirm the diagnosis. Imaging findings must be evaluated in the context of the patient's clinical presentation and recreational activities. Plain radiographic evaluation remains the initial diagnostic modality. Three-dimensional imaging such as MRI and CT often is obtained for the evaluation of labral and cartilage pathology, definition of bony anatomy, and surgical planning...
