Histomorphometric variance of haversian canal in cortical bone of Malaysian ethnic groups

Abstract

This research presents a comparison of haversian canal based microstructural parameters between Malaysian citizens. The ages ranges from 22-58 which was divided into four groups of each decade. In each decade comparison was done on haversian canal based parameters between the two Malaysian ethnic groups Chinese-Indian. Parameters in long bones femur, tibia, fibula, humerus, ulna and radius were measured under microscope by obtaining the bone thin section of 30 microns from the mid-shaft. Eight microscopic images were taken from each specimen having an observation region of 1.228mm2 for each image. In the third and sixth decade, haversian canals showed relatively larger total covered area in Indian bone specimens. Haversian canal radius was found to be greater in Chinese bone specimen in the fourth decade. The fifth decade showed no differences. Further studies are required to validate the outcomes, compare other ethnic groups and development of automated microstructures identification and measurement tools.
