Pathomechanism and diagnosis of femoroacetabular impingement / 中国矫形外科杂志

ABSTRACT

The pathomechanism of hip pain and hip osteoarthritis is multi-factorial.Recently,abnormal impingement between proximal femur and the acetabular rim,femoroacetabular impingement(FAI),has been recognized as a relatively common and possibly prearthritic cause of these symptoms.Accurate diagnosis of the impingement disease pattern is the basis of successful surgical care.The article summarizes the pathomechanism of three types of femoroacetabular impingement and important diagnosis criteria.In addition,this paper further explores requirements for a diagnostic pelvis radiograph and multiple-parameters in pelvic imaging concerning femoroacetabular impingement,such as acetabular retroversion alpha angle,offset,the offset ratio.It will improve the diagnostic rate of FAI and formulating a reasonable treatment plan,so that the therapeutic effect of hip joint disease is improved.
