Next to the femoral neck, there are two protrusions known as greater and lesser trochanters which serve as sites of muscle attachment. In primitive tetrapods, the main points of muscle attachment along the femur are the internal trochanter and third trochanter, and a ridge along the ventral surface of the femoral shaft referred to as the adductor crest. The pubis, ischium, and ilium together constitute the pelvis while the thigh bone is the femur.

The femur, also known as the thigh bone, is one of the largest and strongest bones in the body extending from the hip joint all the way down to the knee joint. With that being said, certain medical conditions can weaken the bone and make it more vulnerable to fracture. The neck of the femur is generally minimal or absent in the most primitive forms, reflecting a simple attachment to the acetabulum.

Bone Markings: [posterior view / right femur]: Shaft (Corpus femoris) is the cylindrical, anteriorly arched body of the femur. Internal bleeding from a broken femur can be significant, which makes this one of the few simple fractures that can be considered life-threatening. The other two borders of the femur are only slightly marked: the lateral border extends from the antero-inferior angle of the greater trochanter to the anterior extremity of the lateral condyle; the medial border from the intertrochanteric line, at a point opposite the lesser trochanter, to … Bursitis can affect any joint in the body, including the hip and knee. The hip joint is made up of two bones: the pelvis and the femur (the thighbone). Bone lesions are lumps or masses of abnormal tissue produced when cells within the bone start to divide uncontrollably.
