16 Sesamoid bones in the hands of healthy patient: case report

ABSTRACT

The sesamoid bones are round or oval bones that are located within tendons, and most theories consider that sesamoid bones in humans develop in response to local mechanical stress on a joint. Although their function is not well understood, it is known that they act as a pulley modifying the angle of movement and their insertion. They are mostly inconsistent, which is why they tend to be supernumerary and are located in different parts of the body at the level of the extremities, with the patella being the largest, most constant and best known. The prevalence and distribution of sesamoids in the hand varies between different populations and sex. They are rarely reported since they are only considered anatomical variants, but clinically there are several pathologies related to the sesamoid bones in the hand such as trauma, degenerative disorders, giant cell tumors, osteochondroma, avascular necrosis, tendon ruptures, genetic disorders and attention should be paid in patients with acromegaly where their length is increased. In this article, we report a total of 16 sesamoid bones, symmetrically distributed 8 ineach hand of a healthy individual treated in the Plastic Surgery Department of the "Dr. Rubén Leñero" Hospital in Mexico City. In the literature reviewed, we did not find a report with the presence of so many sesamoid bones in both hands, which motivated us to report it
