The Third Trochanter in Human Femur : A Case Report

Abstract

During routine osteology demonstration class of 100 numbers of Under Graduate M. B. B. S. Students at the Department of Anatomy, Regional Institute of Medical Sciences, Imphal, Manipur, we have come across one unique and unusual finding that one right human femur was found to be present with an elongated bony projection along the superior border of the gluteal tuberosity. It was found to be present about 7cm below the tip of the greater trochanter and the bony projection was about 1.70cm in length. It was localised laterally to the line connecting the tip of greater trochanter with superior bifurcation to the linear aspera. No any other anatomical abnormality was found in the above mentioned femur. The other remaining portion of the said femur was found with their normal anatomical features. The photograph of the right human femur mentioned above was taken for proper documentation and for ready reference. This case report has provided some additional evidence to the researchers and anatomists to enhance the understanding of the human femur more particularly the third trochanter and its significance. The present case study revealed an unusual finding as referred to above.
