During the postnatal development the radiographic pictures of the bones of the elbow joint show that there are five ossification loci which are; the ossification locus of the distal epiphysis of the humerus which is fused at the age of 32 weeks, the ossification locus of medial epicondyle of the humerus which is fused at the age of 25 Months, the ossification loci of the proximal epiphysis of the radius which fused at age of 11 months, the ossifaction loci of the proximal epiphysis of the ulna which is fused at the of 48 months, and the ossificalon loci of the lateral epicondyle of the humerus which could not be traced.
