Reliability of 3D quantitative displacement of femoral neck fracture site measured via CT and its correlation with femoral head avascular necrosis: a retrospective cohort study

Key Points

• CT-measured 3D displacements demonstrate superior reliability for assessing femoral neck fractures.
• This method shows a strong correlation with avascular necrosis, outperforming traditional 2D assessments.
• Retrospective cohort analysis across different displacement directions indicates variable impact on avascular necrosis.
• Findings highlight the need for further investigation into 3D CT imaging for improved fracture management.
