US in pubalgia.

There is considerable confusion over the word "pubalgia" with regard to the definition and the etiological causes of this condition. The term pubalgia should be used to indicate disabling pain affecting the pubic region in people who practise sports. Pubalgia affects 10% of those who practise sports and it is particularly prevalent in football players. According to the literature, about 40% of cases of pubalgia are caused by overuse of the symphysis pubis with progressive lesions affecting the rectus abdominal muscles, adductors (rectal-adductor syndrome) and the symphysis itself (osteitis pubis and joint injury). An initial study of the tendons is carried out by ultrasound (US) whereas magnetic resonance imaging (MRI) should be performed to study the bones and joints.Another 40% of cases of pubalgia are caused by "sports hernia" defined as anteroinferior abdominal wall insufficiency. These alterations can only be identified at dynamic US examination.About 20% of cases of pubalgia are caused by diseases of the neighboring structures or joints such as diseases of the hip, iliopsoas, hamstring, sacred iliac or nerves, or by urogenital diseases.
