longest and strongest bone in body. femoral shaft is bowed slightly anteriorly. proximal end of femur consists of a head, which is received by the acetabulum of the pelvis. femoral head has a small notch, the fovea capitis femoris, for ligament attachment. femoral neck, joins the head and shaft, angles upward approx 120 degrees and forward (in anteversion) approx 15 degrees. The greater (lateral) and lesser (medial) trochanters are large processes on the posterior proximal femur. greater trochanter is a prominent positioning landmark that lies in the same transverse plane as public symphysis and coccyx. intertrochanteric crest runs obliquely between trochanters; intertrochanteric line runs anteriorly parallel to the crest. The femoral shaft presents a long, narrow ridge posteriorly called the linea aspera.
