ANATOMICAL RESEARCH ASSESSING THE PREVALENCE OF THE SUPRATROCHLEAR FORAMEN OF THE HUMERUS IN HUMAN- AN IN VITRO STUDY

Abstract

Background: A little hole in the humerus located above the humerus trochlea is known as the supratrochlear foramen, 
and it was initially identified by Meckel in 1825. Understanding the supratrochlear foramen of the humerus is essential 
for managing supracondylar fractures, creating treatment plans, and identifying radiographic abnormalities.  
Objective: To assess the prevalence of the supratrochlear foramen of humerus in the people. 
Methods: In order to determine the prevalence of a supratrochlear foramen in humans, 120 dry humerus bones were 
analysed. The supratrochlear foramen of the humerus was one of the criteria evaluated in this investigation. We 
measured the dimensions of supratrochlear foramen using a digital vernier calliper. The observed supratrochlear 
foramen was also photographed in the present study. 
Result: Upon inspection, 10 humerus showed evidence of the supratrochlear foramen. Only supratrochlear foramen of 
left side was visible. In 8.3% of all humerus examined, supratrochlear foramen was found to be highly prevalent. In four 
humerus, the supratrochlear foramen was seen to be circular in shape; in the other four humerus, it was oval in shape; 
and in two humerus, it was slit-shaped. 
Conclusion: the current study's findings are essential for determining the frequency and occurrence of the 
supratrochlear foramen of the humerus and for contrasting it with previous research in the literature.
