The investigation intended to quantify lumbar lordotic and lumbosacral Angle (LLA) in patients with lower back pain. The examination was completed on 54 patients with chronic low back pain, in a multispecialty hospital in India, over a period of 6 months for lumbosacral lateral radiographs. The lumbar lordotic angles were measured by Ferguson's technique. The age group ranged from 21-65 years with the weight range of 33 to 88 kg, height range of 133 to 182 cm, and BMI range of 15.2 to 36.6 (Kg/ m2). The mean weight, height, and BMI were 59.8 kg, 159.1 cm, 23.7 kg/m2 respectively. The overall range of peak kilovoltage was 60 to 75 kVp. The mAs range was 53 to 78. The mean lumbar lordotic angle (LLA) of the study population was 50.1 degrees with a range of 23 to 68 degrees.
