The morphologic relationship of the lesser trochanter with the femoral neck and greater trochanter

Abstract

Background: The anatomy of the proximal femur comprises important landmarks for many orthopedic surgical procedures. However, this area exhibits morphological differences depending on race, gender and age. Besides being the insertion area of the hip flexor muscles, the lesser trochanter is also used as an angular reference in many orthopedic surgical procedures. The aim of this study is to investigate the morphologic relationship of the lesser trochanter with the femoral neck and greater trochanter.Methods: Around 67 dry femur bones (32 left, 35 right) belonging to humans of unknown gender that belong to the Ankara University Medical Faculty, Department of Anatomy were used in this study. The morphologic relationship of the lesser trochanter (TRMI) with the femoral neck (FN) and greater trochanter (TRMJ) was studied and the results were provided in a table.Results: The measured mean lesser trochanter and greater trochanter tip distance was 67.5±4.9mm (60mm-75mm). The angle between the tip of the lesser trochanter and the center of the femoral neck was measured as 35.050±5.060 (290-420) degrees. The distance between the tip of the lesser trochanter and the center of the femoral neck was measured as 15±2.8mm (10mm-20mm).Conclusions: In addition to the angular relationship of the lesser trochanter with the femoral neck, its relationship in terms of distance with the greater trochanter and femoral neck are the anatomic relationships that are noteworthy for the lesser trochanter, which is used as a landmark during orthopedic surgical procedures.

Morphometric Study of Proximal End of the Fully Ossified Human Femur: A Cross-Sectional Study

“…The mean length of the intertrochanteric crest of the right femur was 5.92± 0.52 cm, and the left femur was 6.20±0.87 cm, and their difference was identified to be statistically significant. Akkaya et al [31] suggested that the length of the intertrochanteric crest of the right femur was 67.5±4.9 mm, and of the left femur was 67.5±4.9 mm, which is almost to our findings. Khanal et al [21] studied the measurements of proximal and distal fragments in the Nepalese population and found the length of the intertrochanteric crest of the right femur was 5.10 ±0.74 cm of the left femur was 4.98±0.66 cm which is lower than our study.…”

“…A measure of association between two variables is defined as the correlation [31]. The weight-bearing bones of the lower limb have the highest degree of correlation with stature [13] Chandran, in his study on South Indian females, concluded that all the incomplete measurements showed a positive correlation with the femoral length.…”
