The aim of the study is to understand the effect of spinal deformity and altered sagittal plane parameters of lumbosacral complex on acetabular cup position in THA.
Investigators will Find out if there is change in the acetabular cup including the abduction and anteversion angles in patients who had THA and has spinal deformity
