Inguinal hernia sectional imaging with CT or MRI, the major differential in diagnosing indirect inguinal hernias is differentiation from spermatic cord lipomas, as both can contain only fat and extend along the inguinal canal into the scrotum. On axial CT, lipomas originate posterolateral to the cord, and are located inside the cremaster muscle, while inguinal hernias lie anteromedial to the cord and are not intramuscular. Large lipomas may appear nearly indistinguishable as the fat engulfs anatomic boundaries, but they do not change position with coughing or straining. Differential diagnosis of the symptoms of inguinal hernia mainly includes the following potential conditions: There
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
