Lateral center-edge angle in femoroacetabular impingement: from the sourcil or the rim of the acetabulum?
Medicine (Baltimore)
November 2024
Department of Orthopedics, Dokuz Eylül University Faculty of Medicine, Izmir, Turkey.
The correlation between clinical outcomes and preoperative/postoperative measures of the lateral center-edge angle (LCEA) will help establish the cutoff values for this measurement and determine whether to obtain it from the lateral acetabular rim (LCEAR) or the lateral end of the sourcil (LCEAS). The hypothesis was that the LCEAS would be more sensitive than the LCEAR. An upper cutoff value of LCEA could predict better functional outcomes in FAI patients.

Article Synopsis
- The study investigates the 3D anatomy related to the acetabular sourcil, which is used in calculating angles critical for diagnosing hip dysplasia through various imaging techniques.
- Researchers aimed to assess the consistency of measurements (LCEA and ACEA) taken by different observers and how those measurements relate to the anatomy being evaluated.
- Using CT scans from 20 patients undergoing hip surgeries, the study generated detailed models to better understand the distinct anatomical regions that influence these radiographic measurements.
A Study on Imaging Risk Factors for Hip Osteoarthritis.
Orthop Surg
October 2024
Department of Orthopedics, The Second Hospital of Shanxi Medical University, Taiyuan, China.
Objective: Due to low prevalence and few studies, the morphologic risk factors for hip osteoarthritis (HOA) in Chinese population remain unknown. The purpose of this study was to investigate the relationship between 10 radiographic parameters measured via anteroposterior pelvic X-ray radiography and HOA in Chinese population.
Methods: Thirty-three patients who required total hip arthroplasty for unilateral HOA (2017-2022) and 132 healthy individuals were selected for this case-control study.
False-Profile Radiograph Sourcil-Edge and Bone-Edge Measurements Correlate to Different Weightbearing Regions of the Acetabulum: A 3-Dimensional Analysis.

Article Synopsis
- The study investigates how the acetabular sourcil and bone edges, common radiographic markers, relate to the weightbearing area of the acetabulum, highlighting potential confusion in surgical settings.
- It was hypothesized that the sourcil edge indicates anterolateral coverage while the bone edge shows anterior coverage in the acetabulum.
- Findings revealed that the sourcil edge aligns with the area behind the anterior inferior iliac spine (AIIS), while the bone edge targets a weightbearing region beneath it, with significant implications for hip surgeries.
