Characteristics of the Acetabulum in Patients at Dr. Saiful Anwar General Hospital from 2021 to 2023

Abstract

Introduction: The pelvis and acetabulum are critical anatomical structures that support body weight and protect vital organs. This study aims to gather data on various anatomical parameters of the pelvis, such as the Acetabular Index, Wiberg's Center-Edge Angle (CEA), Femoral Neck Angle, Hip Joint Space, Skinner’s Line, and Teardrop Distance, to better diagnose orthopaedic conditions. Methods: This descriptive study analyzed data on patients who underwent AP pelvic radiography at Dr. Saiful Anwar General Hospital in Malang between January 2021 and December 2023. The data was collected through the Radiology Information System (RIS). The study included patients aged 18 -40 with adequate AP pelvic radiographs and no history of congenital abnormalities, fractures, ligament injuries, or surgeries. The data was analyzed using SPSS 25 to find each parameter's mean and standard deviation. Results: The study examined the acetabulum's radiological parameters in 200 subjects. Results showed an Acetabular Index greater than 33°, indicating a risk of hip dysplasia. The central edge angle was within the normal range, the Femoral Neck Angle was below normal, indicating a tendency toward coxa vara; the Hip Joint Space was normal, the Teardrop Distance was within the normal range, and the Tönnis Angle was within the normal range. Conclusions: The study found that the mean Acetabular Index was slightly above the normal range, followed by the average Tönnis Angle, which was 5.10°. This indicates a tendency toward inclination, potentially leading to hip dysplasia, and other measurements are normal.
