Résumé
Background: Femoral neck anteversion angle is the angle which measures the anterior rotation of the neck of thefemur around the shaft. Its variation in the various population groups is attributed to various factors such asheredity, diet, climatic factors and lifestyle. This angle is clinically significant for orthopedicians while doinghip arthroplasties and osteotomies where it is pertinent to restore the anatomy of proximal femur for stability ofthe hip joint.Context and purpose of the study: There is no baseline data of Femoral Neck Anteversion angle for Central Indianpopulation. The present study was aimed to fill this lacuna and to give the normal values of femoral neckanteversion angle for above specified population.Materials and methods: 152 dried femora were procured from department of anatomy consisting of 77 femora ofright side and 75 femora of left side. Anteversion angle is recorded using goniometer. Means were calculated andstatistically correlated for laterality using independent student‘t’ test. p value was thus obtained.Results: Mean anteversion angle of right side was found to be 19.03º ± 12.11º and that of the left side came outto be 18.62º ± 10.8º. Among 152 femora taken, 7 retroverted and 7 neutral verted femora were also found in thestudy.Conclusion: So much variation in the angle of anteversion along with the presence of retroversion (4.6%) andneutral version (4.6%) is a challenge for both implant designer companies as well as orthopedicians. Thus,present study acts as a guide for normal values and range of this clinically significant angle.
