1] During the evolution of bipedal gait and erect posture, the lumbosacral part of vertebral column has undergone maximum modifications leading to the development of Lumbosacral angle (LSA).
According to Datta (2008) [10], the prominence of Lumbosacral angle is due to more extensive anterior surface of the body of fifth lumbar vertebra and the intervertebral disc between L5 and S1, which is much thicker in front than behind.
Lumbosacral angle was measured by goniometer (Fig 2).
It is same as the lumbosacral angle measured by Ferguson's technique in the present study.
In their opinion, the lumbosacral angle measurement is significant in the evaluation of instability and low back pain in 3rd to 6th decades of life.
Hughton et al (2015) [16] while investigating the relationship between Lumbosacral Angle (LSA) and chronic low back pain (LBP) among females, have found significant positive correlations between degree of LSA and ageing; chronic LBP intensity; and LBP related functional limitation.
Stagnara et al (1982) have measured the lumbosacral angle and found it to be 210 (range 10[degrees]-35[degrees]).
The lumbosacral angle (LSA) or slip angle is the angle between the lines on the superior endplates of L5 and S1.
1,2] Its superior wide base articulates with fifth lumbar vertebra at lumbosacral angle and its blunted caudal apex articulates with coccyx.
Outside of this neutral zone, we modeled passive properties to vary linearly with the lumbosacral angle using stiffness coefficients reported by White and Panjabi: 1.
The lumbosacral angle doubled to 64[degrees] compared to our closest extant quadripedal cousin, the chimpanzee (Abitol, 1987).
The sacra, bone articulates with the coccyx caudally and the wide base which lies superiorly binds to the fifth lumbar vertebra and forms a lumbosacral angle.
