Background: Proximal femoral geometry(PFG) plays a role in the biomechanics of the hip. During total hip replacement detailed efforts are made to restore this biomechanics in other to ensure patients satisfaction and implant survival. There are variations in these parameters. Ethnicity is one of the most influential factors accounting for these variations. Aim: To determine the values of the parameters of the proximal femoral geometry among the ethnic Igbos of the South Eastern Nigeria, determine any correlation between these parameters, and compare these values with known populations as well as discuss the clinical application in total hip replacement and other hip surgeries. Materials and Method: Seven hundred and sixteen (716) femoral bones taken from the osteology unit of department of anatomy of University of Nigeria Enugu Campus (UNEC) were screened and proximal femoral parameters measured using Vernier calipers. Results: There were 356 right and 360 left femoral bones with the following values: Femoral Neck Anteversion Angle (FNAVA): M=19.04°, SD=2.075°, Proximal Femoral Length(PFL): M=73.24mm,SD=7.622, Femoral Head Vertical Diameter(FHVD):M= 44.64mm, SD=3.134, Femoral Head Transverse Diameter(FHTD),M=44.55mm, SD=3.379mm, Femoral Head Diameter(FHD),M=44.60mm, SD=3.119mm, Femoral Neck Anterior Length(FNAL), M=31.86mm, SD=5.383mm, Femoral Posterior Neck Length(FPNL):M=22.23mm, SD=3.520mm, Femoral Neck Diameter (FND), M=32.71mm,SD= 3.315mm, Proximal Femoral Width Head to Side (PFWHS), M=89mm.80,SD= 10.331mm, Proximal Femoral Width Side to Side (PFWSS), M=31.47mm, SD=2.812mm, Femoral Neck Shaft Angle(FNSA), M=132.15°, 7.305°. Conclusion: The parameters of the proximal femoral geometry of the ethnic Igbos of the South East of Nigeria, differed from other populations and exhibited laterality.
