The Unnamed Fossa is the insertion point of the Superior Gemellus, Obturator Internus and Inferior Gemellus, which all act as lateral rotators of the thigh. The lesser trochanter is a cone-shaped extension of the lowest part of the femur neck.
This line is used to measure the acetabular angle and as a reference for Perkin line. (B) Perkin line is perpendicular to Hilgenreiner line, touching the lateral margin of the acetabular roof. [5] This leads to four quadrants and a normal femoral head has to be located in the inferomedial quadrant.
