Track Sign

An abnormal anatomic variant of the femur in which the linea aspera or pilaster—site of attachment—of the major adductor and extensor muscles is more prominent than usual and is located on the posterior midshaft, thus having a radiodense ‘tube-in-a-tube’ appearance. This should not be confused with the blade of grass sign of Paget’s disease of bone
