The greater trochanter is a large, prominent projection on the proximal femur (thighbone) that serves as a major attachment point for several hip muscles, particularly the gluteal muscles. This bony prominence acts as a lever arm, providing mechanical advantage for the muscles that abduct and rotate the hip. It is a crucial landmark for hip function and is essential for efficient walking and maintaining balance.
The term "trochanter" comes from the Greek word "trokhos," meaning wheel or pulley, referring to its role in movement. The word "greater" distinguishes it from its smaller counterpart (the lesser trochanter) on the same bone.
