Kuroda Y, Hashimoto S, Saito M, et al. - This study was performed to evaluate the relationship between labral length and radiographic parameters of lateral and anterior acetabular coverage and the femoro-epiphyseal acetabular roof (FEAR) index in patients with developmental dysplasia of the hip (DDH). Researchers retrospectively examined data from patients with DDH who visited our hip joint clinic for the first time due to hip symptoms. They characterized DDH presence as a lateral center-edge angle (LCEA) ≤ 25°. The Pearson’s correlation coefficients (r) and simple linear regression analyses were conducted to ascertain the relationship of the lateral and anterior labral lengths with the radiographic parameters including the LCEA, acetabular roof obliquity, FEAR index, anterior wall index, and vertical center anterior angle. It was shown that the lateral labral length had a strong positive association with the FEAR index. Moreover, an association was found between anterior labral length and anterior dysplasia.
