What is the name of the projection on the medial/superior portion of the femur?

The projection on the medial/superior portion of the femur is known as the lesser trochanter. This bony prominence serves as an important site for muscle attachment, particularly for the iliopsoas muscle, which is crucial for hip flexion.

The lesser trochanter is located on the femur just below the neck of the femur, and it is distinct from the greater trochanter, which is a larger, more laterally positioned projection on the femur. Understanding the anatomy of these projections helps in the assessment of hip injuries and in surgical procedures involving the hip area. The femoral head, on the other hand, is the rounded top part of the femur that fits into the hip joint, and the patella is the kneecap, which is unrelated to the femur's projections.
