Hernia when abdominal contents pass into the weak area at the posterior wall of the femoral canal. They can be hard to distinguish from the inguinal type (especially when ascending cephalad): however, they generally appear more rounded, and, in contrast to inguinal hernias, there is a strong female preponderance in femoral hernias. The incidence of strangulation in femoral hernias is high. Repair techniques are similar for femoral and inguinal hernia. A "Cooper's hernia" is a femoral hernia with two sacs, the first being in the femoral canal, and the second passing through a defect in the superficial fascia and appearing almost
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
