Vastus medialis is one component of quadriceps femoris. (Standring 2016). It originates from the femur with attachments to the intertrochanteric line, spiral line, linea aspera, and medial supracondylar line (Standring 2016). It attaches to the medial aspect of the patella and to the quadriceps femoris tendon (Standring 2016).

As a synovial joint (see joint classification), the hip joint is surrounded by a fibrous capsule. Thickenings of this capsule form the three external ligaments of the hip. These ligaments spiral from the pelvis to the femur, providing strong support for the joint. The most anterior ligament is the iliofemoral ligament, also known as the Y-ligament because it has a characteristic inverted Y-shape. This ligament arises from the anterior inferior iliac spine and acetabular rim of the pelvis, winding anteriorly and distally to attach at two points on the intertrochanteric line on the proximal anterior femur. The major role of this ligament is to prevent hyperextension of the hip joint. The pubofemoral ligament has an anteroinferior position. It attaches to the obturator crest, laterally on the pubic bone and runs laterally and distally to blend with the iliofemoral ligament at its femoral attachment. This ligament prevents excessive abduction of the hip joint. The third capsular ligament lies posterior to the hip joint. The ischiofemoral ligament arises from the ischial part of the rim of the acetabulum, spiralling proximally and laterally to attach to the superior surface of the neck of the femur, just medial to the greater trochanter. This ligament is the weakest of the three. All of the ligaments become tighter during hip extension, preventing hyperextension and pushing the head of the femur into the acetabulum and maximizing the stability of the joint.

The blood supply to the femoral head is a prime consideration in treating femoral neck fractures. The blood supply comes via the hip capsule. The joint capsule anteriorly inserts along the intertrochanteric line and posteriorly half way along the femoral neck. Fractures proximal to the hip capsule are intracapsular and those distal to the capsule are extracapsular fractures.

The patient was referred again to the orthopedic surgeon who prescribed an MRI (Figure 4) that showed a “severe alteration of the signal of the right femoral head which spreads all over the femur neck until the region of the intertrochanteric line. These findings suggest a severe BME associated with a homolateral effusion of the hip joint.”
