Vastus intermedius

Vastus Intermedius

The Vastus Intermedius is a muscle located in the anterior compartment of the thigh. It is one of the four muscles that make up the quadriceps muscle group, along with the vastus lateralis, vastus medialis, and rectus femoris.

Anatomy

The Vastus Intermedius originates from the anterior and lateral surfaces of the femur body, and it is located deep to the rectus femoris but superficial to the femur. Its fibers end in a superficial aponeurosis, which forms the deep part of the quadriceps tendon.

Function

The primary function of the Vastus Intermedius is to extend the knee joint. It is also involved in stabilizing the patella and the knee joint during walking or running.

Clinical significance

Injury or strain to the Vastus Intermedius can result in pain and limited mobility. It can be caused by overuse, trauma, or imbalances in the quadriceps muscle group. Treatment usually involves rest, physical therapy, and in severe cases, surgery.
