It is located on the posterior surface of the femur. fracture of the proximal femur located in the metaphyseal bone in the region between the greater and lesser trochanters. An elevation between the middle and proximal third of the crest is known as the quadrate tubercle. It traverses between the greater and lesser trochanters and distally is continuous with the spiral line of the femur. Learn more. Just like the intertrochanteric crest on the posterior side of the femoral head, the intertrochanteric line marks the transition between the femoral neck and shaft.
