Quadrate tubercle

The quadrate tubercle is a small tubercle found upon the upper part of the femur, that serves as a point of insertion of the quadratus femoris[1] along with the intertrochanteric crest and the linea quadrata.

The quadrate tubercle is located about the junction of the upper one-third and lower two-thirds, on the intertrochanteric crest. The size of the tubercle varies; it is not always located on the intertrochanteric crest. Adjacent areas can also be part of the quadrate tubercle, such as the posterior surface of the greater trochanter or the neck of the femur. In a small anatomical study it was shown that the epiphysial line passes directly through the quadrate tubercle.[2]
