The humerus is the longest and heaviest of the bones of the upper limb. In the elbow region, the humerus condyle is composed of the trochlea, the capitulum, and related fossae. The coronoid fossa, located on the anterior surface, receives the coronoid process of the ulna when the forearm is flexed. The olecranon fossa, located on the posterior surface, is large and deep and receives the olecranon of the ulna, when the forearm is extended. The two fossae are separated by a thin bony lamina that usually allows the passage of light. In some cases, the two fossae are separated by a non‐calcified membrane which, in dry bones, gives rise to an opening or perforation, called the supratrochlear foramen or septal foramen. Individuals with this anatomical variation are able to hyper‐extend the elbow joint. In the present study, 30 left humerus and 25 right humerus were evaluated and 16.7% of the left humerus and 15% of the right humerus presented the septal opening. With the aid of a digital caliper, the length, diameter and circumference of the middle portion of the diaphysis and the inter‐epicondylar distance of the humerus with and without the septal foramen were obtained. With the aid of an analytical scale, the weight of the bones was obtained and, later, the weight/length ratio was calculated for each humerus. Statistical analysis showed no differences between the right and left normal humerus, as well as between those with septal formamen, in none of the analyzed parameters. When we compared the humerus with and without the septal foramem, the diameter and circumference of the middle portion of the diaphysis, and the inter‐epicondylar distance were significantly smaller in the humerus with the septal foramen. Our data suggest that the presence of the septal foramen may be related to a reduction of the standard anthropometric measurements of the humerus.
