Femoral neck
Upper extremity of right femur viewed from behind and above.
Right femur. Anterior surface.
Latin	collum femoris
Gray's	subject #59 243
MeSH	femur+neck

The femur neck or neck of the femur is a flattened pyramidal process of bone, connecting the femoral head with the femoral shaft, and forming with the latter a wide angle opening medialward.

Angle of inclination

The angle is widest in infancy, and becomes lessened during growth, so that at puberty it forms a gentle curve from the axis of the body of the bone. In the adult, the neck forms an angle of about 125° with the body, but this varies in inverse proportion to the development of the pelvis and the stature. The angle decreases during the period of growth, but after full growth has been attained it does not usually undergo any change, even in old age; it varies considerably in different persons of the same age.

In the female, in consequence of the increased width of the pelvis, the neck of the femur forms more nearly a right angle with the body than it does in the male.

It is smaller in short than in long bones, and when the pelvis is wide.

In addition to projecting upward and medialward from the body of the femur, the neck also projects somewhat forward; the amount of this forward projection is extremely variable, but on an average is from 12° to 14°.

Structure

The neck is flattened from before backward, contracted in the middle, and broader laterally than medially.

The vertical diameter of the lateral half is increased by the obliquity of the lower edge, which slopes downward to join the body at the level of the lesser trochanter, so that it measures one-third more than the antero-posterior diameter.

The medial half is smaller and of a more circular shape.

The anterior surface of the neck is perforated by numerous vascular foramina.

Along the upper part of the line of junction of the anterior surface with the head is a shallow groove, best marked in elderly subjects; this groove lodges the orbicular fibers of the capsule of the hip-joint.

The posterior surface is smooth, and is broader and more concave than the anterior: the posterior part of the capsule of the hip-joint is attached to it about 1 cm. above the intertrochanteric crest.

The superior border is short and thick, and ends laterally at the greater trochanter; its surface is perforated by large foramina.

The inferior border, long and narrow, curves a little backward, to end at the lesser trochanter.
