ulna, humerus and femur linear lengths were directly correlated with the level of osteocalcin and P however, they showed a negative correlation with the level of. Suppose a study was made investigating the relationship between the diagonal measure of Given a humerus length of 50 cm, estimate the length of the femur.

The relationship of the humerus and femur length in centimeters is compared with the gestational age in weeks. The multiple correlation equation of humerus and femur length with the gestational age was deduced.
It was observed that the diaphyseal length of humerus and femur gradually increased from 15 weeks to 40 weeks of gestation and by applying multiple correlation, a formula was derived to calculate the gestational age. The measurement of the humerus and femur length in cm can be an important additional parameter for estimating gestational age along with other parameters and can be used to predict the gestational age of fetuses belonging to that geographical area using the derived formula.

In the forearm are the radius —on the thumb side of the forearm—and the ulna ; in the lower leg are the tibia the shinbone and the fibula. The radius corresponds to the tibia and the ulna to the fibula.
[Proportions of the femur and humerus in relation to bone length].
The knee joint not only is the largest joint in the body but also is perhaps the most complicated one. The bones involved in it, however, are only the femur and the tibia, although the smaller bone of the leg, the fibula, is carried along in the movements of flexion, extension, and slight rotation that this joint permits.
The very thin fibula is at one time in fetal development far thicker relative to the tibia than it is in the adult skeleton. Left The radius and the ulna, bones of the forearm; right the fibula and the tibia, bones of the lower leg. At the elbowthe ulna forms with the humerus a true hinge jointin which the actions are flexion and extension.
In this joint a large projection of the ulna, the olecranon, fits into the well-defined olecranon fossa, a depression of the humerus. The radius is shorter than the ulna.
Its most distinctive feature is the thick disk-shaped head, which has a smoothly concave superior surface to articulate with the head, or capitulum, of the humerus.
The head of the radius is held against the notch in the side of the ulna by means of a strong annular, or ring-shaped, ligament. Although thus attached to the ulna, the head of the radius is free to rotate.
As the head rotates, the shaft and outer end of the radius are swung in an arc.
