[Femoroacetabular impingement as a cause of inguinal pain].

Femoro-acetabular impingement is an anatomical disturbance of the hip, caused by a deformity of the acetabulum, femur or both that causes an abnormal contact between both structures during certain movements. Its prevalence is 10 to 15% and causes chronic inguinal pain. It can be confused with several other causes of inguinal pain such as hernias, facet syndromes, a renal colic, etc. Patients with this condition are usually young individuals with inguinal pain that may appear after a minor trauma. During examination, pain may be elicited by infernal rotation and abduction movements of hip, flexed in 90 degrees . Plain hip X ray is the most commonly used diagnostic method. Non-steroidal anti-inflammatory drugs and physical therapy can be used to alleviate pain, but the definitive treatment is surgical.
