Abstract

Introduction: The human femoral third trochanter is described as a projection from the proximal aspect in the upper part of gluteal tuberosity. This projection could be in the form of an oblong, rounded or conical shape. This projection is called third trochanter with reference to the greater trochanter and lesser trochanter. Studies on the third trochanter are comparatively less in number.
Materials and Method: 100 human femora of unknown sexes from the Department of Anatomy, Government T.D Medical College, Alappuzha, Kerala, were inspected to estimate the occurrence of third trochanter.
Result: The third trochanter was present in 13 bones (13%). The frequency of occurrence was 13.46% in left and 12.5% in right. The mean vertical length was 15.81 mm and the mean breadth was 8.48 mm.
Conclusion: The third trochanter of femur with an incidence of 13% in the present study might potentially influence the fracture line in pertrochanteric fracture. Its presence should be taken into consideration while modeling the pre contoured femoral plates.
