The contour of the femoral head-neck junction as a predictor for the risk of anterior impingement
2002
The Journal of Bone and Joint Surgery
I mpingement by prominence at the femoral head-neck junction on the anterior acetabular rim may cause early osteoarthritis. Our aim was to develop a simple method to describe concavity at this junction, and then to test it by its ability to distinguish quantitatively a group of patients with clinical evidence of impingement from asymptomatic individuals who had normal hips on examination.
