Diagram of the femur showing the trochanteric fossa

The trochanteric fossa is a depression located on the femur, the long bone of the thigh. It is situated on the medial surface of the greater trochanter, which is a prominent bony projection on the proximal end of the femur.

Anatomy

The trochanteric fossa is found on the posterior aspect of the greater trochanter. It serves as the site of attachment for several muscles, including the obturator externus and the obturator internus. These muscles are part of the group known as the lateral rotators of the hip, which play a crucial role in the lateral rotation and stabilization of the hip joint.

Function

The primary function of the trochanteric fossa is to provide a point of attachment for muscles that are involved in the movement and stabilization of the hip joint. The obturator externus and internus muscles, which attach to this fossa, help in rotating the thigh laterally and stabilizing the head of the femur within the acetabulum of the pelvis.

Clinical significance

Injuries or conditions affecting the trochanteric fossa can impact the function of the hip joint. For example, inflammation or tears in the muscles attached to this area can lead to pain and reduced mobility. Understanding the anatomy of the trochanteric fossa is important for diagnosing and treating hip-related conditions.

 ==Anatomy==
-The trochanteric fossa is a significant anatomical feature of the [[femur]], the longest and strongest bone in the human body. It is located on the medial side of the greater trochanter, a large, irregular, quadrilateral eminence that is palpable in the upper, outer part of the thigh. The fossa is directed medially and downward, and it is bounded by three prominences, two of which can be traced to the posterior border of the base of the neck of the femur.
