RESUMO
Femoroacetabular impingement is the mechanical contact between the femur and the pelvis, frequently between the femur neck and the acetabular rim, whether due to a deformity of the former (cam type) or the latter (pincer type). However, there may be extraarticular causes of impingement. Together with the increased diagnosis of impingement, arthroscopic treatment is increasingly frequent and has become the standard treatment. This report analyzes a case of extraarticular hip impingement caused by contact between the femur and a prominent anteroinferior iliac spine (AIIS), probably due to a healed old avulsion and its later arthroscopic management.

El pinzamiento femoroacetabular corresponde al contacto mecánico entre el fémur y la pelvis, frecuentemente entre el cuello del fémur y el borde acetabular, ya sea por deformidad del primero (CAM) o del segundo (PINCER);1,2 sin embargo, existen causas extraarticulares de pinzamiento.3,4 A la par del aumento en el diagnóstico de pinzamiento se ha hecho cada vez más frecuente el tratamiento artroscópico de éste siendo hoy el estándar de tratamiento.5 En este reporte se analiza un caso de pinzamiento de cadera extraarticular, causado por un contacto entre el fémur y una espina ilíaca antero inferior (EIAI) prominente debido probablemente a una avulsión antigua consolidada, y a su posterior manejo artroscópico.
