Intertrochanteric line
Linea intertrochanterica
Definition
The intertrochanteric line is a prominent bony ridge that demarcates the junction between the anterior surface of the femoral neck and the shaft. Its upper end is situated in close proximity to the anterosuperior angle of the greater trochanter, while the lower end blends with a spiral line (a.k.a. pectineal line) that spirals medially around the shaft, passing beneath the lesser trochanter, and extending to the posterior aspect of the femoral shaft.
Crucial structures connected to the intertrochanteric line include the hip joint capsule, upper and lower bands of the iliofemoral ligament, and the uppermost segments of the vastus lateralis and vastus medialis muscles.
