Evaluation of Ultrasound for Detecting Hip Impingement

Patients are being asked to participate in this study because a previous research MRI of their hips showed that the shape of the head of their thigh bone may indicate FAI of the hip. We have already collected cartilage imaging data and data on how the hip joint moves on people with painful/symptomatic FAI and people with normal hip function. We would now like to compare the motion of the hip joint to those with painful FAI using ultrasound.
