Femoral hernia the two preoperatively. The diagnosis is largely a clinical one, generally done by physical examination of the groin. However, in obese patients, imaging in the form of ultrasound, CT, or MRI may aid in the diagnosis. For example, an abdominal X-ray showing small bowel obstruction in a female patient with a painful groin lump needs no further investigation. Several other conditions have a similar presentation and must be considered when forming the diagnosis: inguinal hernia, an enlarged femoral lymph node, aneurysm of the femoral artery, dilation of the saphenous vein, athletic pubalgia, and an abscess of the psoas. Femoral hernias,
Femoral neck targeting component occurs, early implant failure can result. There are many methods surgeons use to calculate the true centre of the femoral neck. Today the methods broadly fall under two categories: The navigational systems were created to be an accurate means for surgeons to implant components with as much accuracy as possible. Studies have shown that this is largely true, but navigational systems are a very different means of femoral neck targeting, and require a steep learning curve. Below is a comparative analysis of both types of navigational targeting against traditional targeting techniques. A computer-assisted device to calculate the true centre
