The pectineal line is a bony ridge on the shaft of the femur that extends downward from the lesser trochanter, nearly reaching the linea aspera. A rough line that separates the neck and shaft of the femur anteriorly; it passes downward and medially from the greater trochanter to the lesser trochanter and continues into the medial lip of the linea aspera. The femur (thigh bone) at the level of the hip is made up of 4 different parts: the head, neck, greater trochanter, and lesser trochanter. The ischiofemoral ligament blends with the fibers of the circular ligaments and attaches at the intertrochanteric line of the femur.

It traverses between the greater and lesser trochanters and distally is continuous with the spiral line of the femur. Guide-wire insertion Take the guide wire for the long nail and insert it just lateral to the tip of the greater trochanter and in line with the middle of the femoral neck, and slightly lateral to a line corresponding to the anatomical axis of the shaft. An intertrochanteric fracture is a specific type of hip fracture.
