Ī slight ridge is sometimes seen commencing about the middle of the intertrochanteric crest, and reaching vertically downward for about 5 cm. The two trochanters are joined by the intertrochanteric crest on the back side and by the intertrochanteric line on the front. The lesser trochanter is a cone-shaped extension of the lowest part of the femur neck. The trochanteric fossa is a deep depression bounded posteriorly by the intertrochanteric crest on the medial surface of the greater trochanter. The greater trochanter can easily be felt. The highest point of the greater trochanter is located higher than the collum and reaches the midpoint of the hip joint. The greater trochanter is almost box-shaped and is the most lateral prominent of the femur. Here the two trochanters, greater and lesser trochanter, are found. The transition area between the head and neck is quite rough due to attachment of muscles and the hip joint capsule. In skinny people with the thigh laterally rotated, the head of the femur can be felt deep as a resistance profound (deep) for the femoral artery.

Both the head and neck of the femur is vastly embedded in the hip musculature and can not be directly palpated. An abnormal increase in the angle is known as coxa valga and an abnormal reduction is called coxa vara. In the infant it is about 150 degrees and in old age reduced to 120 degrees on average. The collum forms an angle with the shaft in about 130 degrees. long and the diameter is smallest front to back and compressed at its middle. The head of the femur is connected to the shaft through the neck or collum. It has a small groove, or fovea, connected through the round ligament to the sides of the acetabular notch. The head of the femur, which articulates with the acetabulum of the pelvic bone, comprises two-thirds of a sphere. The upper extremity is the shortest femoral extremity, the lower extremity is the thickest femoral extremity. The upper or proximal extremity (close to the torso) contains the head, neck, the two trochanters and adjacent structures. Main article: Upper extremity of femur The upper extremity of right femur viewed from behind and above, showing head, neck, and the greater and lesser trochanter The femur is categorised as a long bone and comprises a diaphysis (shaft or body) and two epiphyses (extremities) that articulate with adjacent bones in the hip and knee. The femur length on average is 26.74% of a person's height, a ratio found in both men and women and most ethnic groups with only restricted variation, and is useful in anthropology because it offers a basis for a reasonable estimate of a subject's height from an incomplete skeleton. Some strength tests show the temporal bone in the skull to be the strongest bone. This depends on the type of measurement taken to calculate strength. By some measures, it is also the strongest bone in the human body. The femur is the largest and thickest bone in the human body. In the general population of people without either genu valgum or genu varum, the femoral-tibial angle is about 175 degrees. The opposite extreme is genu varum (bow-leggedness). In the condition genu valgum (knock knee) the femurs converge so much that the knees touch one another. Human females have thicker pelvic bones, causing their femora to converge more than in males. The angle of convergence of the femora is a major factor in determining the femoral-tibial angle. The two femurs converge medially toward the knees, where they articulate with the proximal ends of the tibiae. The femur is the only bone in the upper leg. In humans the femur is the largest and thickest bone in the body. The top of the femur fits into a socket in the pelvis called the hip joint, and the bottom of the femur connects to the shinbone ( tibia) and kneecap ( patella) to form the knee. In many four-legged animals the femur is the upper bone of the hindleg. The thigh is the region of the lower limb between the hip and the knee. The femur ( / ˈ f iː m ər/ pl.: femurs or femora / ˈ f ɛ m ər ə/), or thigh bone is the only bone in the thigh.
