Background: Femoroacetabular impingement (FAI) is pain due to shape mismatch at the hip joint commonly affecting young athletes, and there are 2 main types depending on which bone has underlying deformity: cam (femoral) pincer (acetabular). Hip arthroscopy an invaluable technique in sports surgeon repertoire, a need for comprehensive tutorial that elucidates best practices nuances. Indications:...

The radiological evaluation of the anterolateral femoral head is an essential tool for the assessment of the cam type of femoroacetabular impingement. CT, MRI and frog lateral plain radiographs have all been suggested as imaging options for this type of lesion. The alpha angle is accepted as a reliable indicator of the cam type of impingement and may also be used as an assessment for the succes...

This report describes the arthroscopic management of a case of incarcerating pincer-type femoroacetabular impingement. The hip joint had a marked restriction of range of motion and secondary pain as a result of osteophytes wrapping around the femoral head down the femoral neck. The patient was treated with staged bilateral hip arthroscopy. The procedures were initially performed through the per...

In 2003, Ganz et al. described anterior femoroacetabular impingement (FAI) as an under recognized cause of early hip osteoarthritis. Impingement is a purely mechanical hip disorder defined as abnormal contact between skeletal prominence of the acetabula rim or femoral head-neck junction that leads to painful, periarticular joint. If untreated, FAI can lead to endstage osteoarthritis of the hip ...
