The etiology of femoroacetabular impingement ( FAI ) is abnormal stresses acting on the proximal femur and the acetabulum resulting from abnormally structural relationship between them caused by various factors. FAI plays an important role in inducing early hip osteoarthritis, and the main manifestation is chronic hip pain. Early diagnosis and early treatment help to improve the quality of life of patients and delay the incidence of arthritis. The common X-ray can provide an important reference for the diagnosis and classiifcation of FAI, and the CT scan can provide multi-faceted and multi-dimensional images for hip joint diseases. The sensitivity and speciifcity of MRI are better for the cartilage damages and soft tissue injuries. Therefore, the diagnosis of this disease is not difficult when the clinical symptoms, signs and imaging are combined together. Conservative treatment of FAI is ineffective, and while better therapeutic effects can be achieved with early open surgery or arthroscopic surgery according to the disease conditions. Because FAI has not been found and studied until recent decades, many doctors still do not know it and often misdiagnose it. The key words included “the femur”, “the acetabulum”, “impingement”, “imaging”, “open surgery” and “arthroscope” in this article.
