Abstract

Femoroacetabular impingement (FAI) is considered a major cause of disability and pain in the hip region and has been related primarily to changes in the bone structure. However, many subjects have anatomical signs of impingement in the acetabulum and femur, but without symptoms. Recent research has suggested that kinematic changes of the pelvis and hip may contribute to this disease, especially during functional activities such as squatting, during negociating stairs as well as long walking. Thus, there is a lack of knowledge about the correlations between morfological deformities, abnormal kinematics of the pelvis and hip, and stress of the articular cartilage in patients with FAI. Therefore, the purpose of this study is to compare the pelvis and hip tridimensional kinematics during functional activities in symptomatic subjects with FAI and healthy subjects. Moreover, the specific purpose is to correlate the radiological findings of hip deformities, the stress on the articular cartilage, and the range of motion in this population. (AU)
