Measurement of Lumbosacral Angle in Normal Nepalese Population by Computed Tomography

The aim of this study was to quantify the lumbosacral angle in Nepalese population who had no history of diseases of the spine. Materials and Methods: This prospective study was performed in the Department of Radiology and Imaging of TUTH. Data were collected over a period of 4 months (July-September 2017) with a total of 105 patients who underwent routine computed tomographic scans of the abdomen. The age, sex, weight, and height were noted, and body mass index (BMI) was calculated. The local security authority (LSA) was measured on a dedicated workstation, in the sagittal orientation of thin reformatted images according to Ferguson's method. Results and Discussion: In this study, the lumbosacral angle varied from 20 to 49 with a mean value of 33.48 (+6.44). The obtained values were also classified according to various age groups, gender, and BMI. There was a significant difference in the values between different age groups, gender, and BMI compared to other patients. Conclusion: The study concluded that the mean lumbosacral angle in Nepalese population is 33.48 and is affected by age, gender, and BMI of the patient.
