Correct Answer � A
Explanation

The structure related to the anterior surface of proximal femur is the intertrochanteric line. It is present at the junction of the neck and shaft of the femur.
The Femur-Proximal
- The proximal aspect of the femur articulates with the acetabulum of the pelvis to form the hip joint.
- It consists of a head and neck, and two bony processes – the greater and lesser trochanter. There are also two bony ridges connecting the two trochanter; the intertrochanteric line anteriorly and the trochanteric crest posteriorly.
Intertrochanteric line – a ridge of bone that runs in an inferomedial direction on the anterior surface of the femur, spanning between the two trochanters. After it passes the lesser trochanter on the posterior surface, it is known as the pectineal line.
- It is the site of attachment for the iliofemoral ligament (the strongest ligament of the hip joint).
- It also serves as the anterior attachment of the hip joint capsule.
