Abstract

Background: Femoral Neck shaft angle (NSA) is the angle formed between the long axis of shaft and long axis of neck of femur. NSA of femur is an important parameter considering the biomechanics of hip joint. The clinical significance of the femoral NSA lies in the forensic science, anthropology, radiological diagnosis and orthopedic surgeries.
Objective: Objective of the study was to find out the neck shaft angle of femur and its clinical significance in Telangana population and correlate with the previous Indian study.
Materials and Methods: A total of 120 (60 right and 60 left) dry femur bones were used for measuring the neck shaft angle. Mean value and Unpaired t-test was used to compare right and left femora.
Results: The mean value of neck shaft angle was 129^o±3.86°. It ranges between 117 to 139. The mean value of right side was 131.5° and left side was measured 132.4°. Mean NSA in male was 130.28° whereas in female 131.42°. There was no significant difference statistically between them.
Conclusion: It is important for medical practitioners to know the normal Morphometric values as well as regional variations of Femur in order to understand and treat different disorders of the Femur and hip joint. Findings of our study can be useful in designing femoral implants for south central India population for various hip joint surgeries
