What types of lesions are most commonly associated with Femoracetabular impingement syndrome?

Femoracetabular impingement syndrome is characterized by abnormal contact between the femoral head and the acetabulum during hip movement, which can lead to pain and decreased mobility. This syndrome can manifest in different forms of bony abnormalities in the hip joint, primarily categorized as CAM lesions, which are typically associated with an aspherical femoral head, and pincer lesions, which are due to overcoverage of the femoral head by the acetabulum.

The correct answer highlights that the most common presentation involves a combination of both CAM and pincer lesions. This mixed presentation is significant because each type of lesion contributes to impingement in different ways. A CAM lesion affects the femoral neck, leading to abnormal contact with the acetabulum during hip flexion, whereas a pincer lesion relates to an overhang of the acetabulum that can create impingement against the femoral head.

The presence of both lesions can exacerbate symptoms and complicate treatment. This mixed configuration is more representative of the varying anatomical variations seen in patients suffering from femoracetabular impingement syndrome than isolated forms of either lesion. Understanding this relationship is crucial for diagnosis and developing a comprehensive treatment plan tailored to the individual's findings and symptoms.
