TROCHANTERIC FOSSA Meaning and
Definition
-
The trochanteric fossa is a distinct anatomical feature found in the hip bone. It refers to a shallow depression or groove located on the lateral aspect of the femur bone, specifically on the greater trochanter. The greater trochanter is a bony prominence located at the proximal end of the femur, serving as a site for the attachment of various muscles, tendons, and ligaments.
The trochanteric fossa is positioned inferiorly and posteromedially to the greater trochanter. It is an indentation formed by the posterior surface of the greater trochanter. The depth and size of this fossa may vary among individuals.
Functionally, the trochanteric fossa serves as an attachment site for the piriformis muscle, which is one of the deep muscles of the gluteal region. The piriformis muscle originates from the anterior surface of the sacrum and passes through the greater sciatic notch to attach to the trochanteric fossa. Its contraction aids in the rotation of the thigh and stabilizes the hip joint.
In summary, the trochanteric fossa is a concave feature located on the greater trochanter of the femur bone. It serves as the attachment site for the piriformis muscle and plays a role in hip joint stability and thigh rotation.

Etymology of TROCHANTERIC FOSSA
The term "trochanteric fossa" is derived from two main sources:
1. Trochanter: The word "trochanter" originates from the Greek word "trokhantēr", which means "runner", "runner's bone", or "strap". In anatomy, a trochanter refers to a prominent bony process involved in muscular attachment, found mainly in the femur (thigh bone). The trochanters of the femur are important for muscle attachment and enabling movements of the hip joint.
2. Fossa: "Fossa" is a Latin term that translates to "ditch", "trench", or "hollow". In anatomy, it is used to describe a depression, groove, or other concave structures in bones or other anatomical features.
