Abstract

Background: Development of Human race took years from four years to two legs. The
lower limb in the process of development modified and consists of hip joint, femur, tibia
and fibula. The hip joint is one of the largest and most stable joints in the body. It is a
multiaxial ball- and-socket joint that has maximum stability because of the deep
insertion of the head of the femur into the acetabulum. The joint depends on the angle
from between the femur neck and the diaphysis, keeping the inferior limbs more distant
from the pelvis and allowing greater rotation of hip joint. The neck-shaft angle is widest
at birth and diminishes gradually until adolescence. It is smaller in females. The neck is
laterally rotated with respect to shaft (angle of anteversion) some 10-15o values of this
angle vary between individuals.
Objective: To measure and compare the difference between neck shaft angle of dry
cadaveric human femur and living human femurradiographically.
Methodology: The angle between the two lines of axes passing through the middle of
neck and middle of shaft is known as Neck shaft angle or angle of Inclination and was
measured by goniometer on a sample of 100 dryfemora.
Results and Conclusion: The mean neck-shaft angle in the present study was
129.62±5.5°. No difference was observed on sides (right and left), with respect to
the neck-shaft angle in cadaveric femur was observed in the present study.
Sidedifference with respect to the neck shaft angle was also noted in the present
study.Left side femora had mean neck-shaft angle of 128.28° which was
comparatively less than on the right side130.64°.
