Morphometric Analysis of the Femur: A Comprehensive Study of the Linea Aspera, Popliteal Surface, and Metaphyseal Vessel Foramina

Abstract

Objective: This study aims to analyze the morphometric characteristics of key anatomical structures on the posterior surface of the femur, particularly the linea aspera and the popliteal triangle. Methods: The study was conducted on 52 adult human femurs from the dry bone archive of the department of anatomy. Measurements of total femur length, linea aspera length, gluteal tuberosity, and the dimensions of the popliteal triangle, including its height, base width, and distances between vascular foramina, were obtained using digital calipers and osteometric boards. Results: The mean femur length was 43.90±2.57 cm. The linea aspera length was recorded as 10.03±1.79 cm, while the height of the popliteal triangle measured 13.13±1.86 cm. The base width of the popliteal triangle was 6.22±0.55 cm, and its midpoint width was 2.17±0.36 cm. A moderate negative correlation was found between linea aspera length and popliteal triangle height, whereas a positive correlation was observed between linea aspera length and popliteal triangle width. Conclusion: The morphometric properties of the posterior femur are crucial for surgical planning. The findings of this study may contribute to the development of anatomy-based surgical strategies in distal femoral procedures, minimizing vascular injuries and improving clinical outcomes.
