PROBING PROXIMAL FEMORAL GEOMETRY: INSIGHTS FROM NECK SHAFT ANGLE IN SOUTHEAST NIGERIAN ADULTS

Abstract

The proximal femur, a critical skeletal structure, is susceptible to various disorders across both pediatric and adult populations. Extensive research has been dedicated to elucidating the parameters that characterize proximal femoral geometry (PFG) and the intricate relationship between the femoral neck and shaft, as noted by Ravichandrain et al. in 2011. Among the pivotal parameters defining this relationship are the Neck-Shaft Angle (NSA), Femoral Head Diameter, and Neck Version, as highlighted by Patron et al. in 2006.This comprehensive exploration focuses on unraveling the nuanced aspects of proximal femoral geometry and its associated parameters. The Neck-Shaft Angle serves as a fundamental metric, reflecting the geometric alignment between the femoral neck and shaft. Understanding the significance of this angle is crucial for diagnosing and comprehending various disorders affecting the proximal femur, both in pediatric and adult populations. Additionally, Femoral Head Diameter and Neck Version are integral components contributing to the overall characterization of proximal femoral geometry. The diameter of the femoral head and the version of the femoral neck play pivotal roles in biomechanical functionality, joint stability, and susceptibility to specific pathologies. This study aims to delve into the intricate details of these parameters, offering insights that contribute to a more comprehensive understanding of the proximal femur's structural dynamics. As researchers strive to enhance diagnostic precision and treatment efficacy, a thorough comprehension of proximal femoral geometry becomes indispensable. The interplay between the femoral neck and shaft, as defined by the NSA, alongside the contribution of Femoral Head Diameter and Neck Version, forms the crux of this investigation. The findings hold promise for refining diagnostic protocols, therapeutic interventions, and preventative measures for disorders affecting the proximal femur.
