Incidence of Supratrochlear foramen of Humerus in North Indian Population

A thin translucent plate of bone usually separates coronoid and olecranon fossa of humerus. In some humerii this plate is perforated and gives rise to an aperture, known as supratrochlear foramen. The present study was conducted on 1776 dried humerii (Right-905, left-871) of which 1352 belong to males and 424 to females. The sex determination of humerus was determined by using Vernier sliding calipers by measuring the maximum length, circumference of midshaft, vertical and transverse diameters of head and maximum medial epicondylar breadth of humerus to document the incidence of supratrochlear foramen in North Indian population. The transverse and vertical diameter of the supratrochlear foramen was measured by using digital Vernier calipers.. The supratrochlear foramen was found in 24.10% of humerii. The incidence was more common on left side (28.13%) as compared to right (20.22%). Oval, round and triangular shapes of the supratrochlear foramen were observed among which the oval shape was found to be maximum. The knowledge of higher incidence of supratrochlear foramen in Indians will be helpful to orthopaedic surgeons and radiologists in treating and interpreting the pathology in this area respectively.
