To investigate whether the CT Hounsfield Unit (HU) value of the femoral head can differentiate femoral neck fractures from intertrochanteric femoral fractures and predict the complexity of intertrochanteric fractures.
Approach:
Study Design: A retrospective analysis of 234 patients (117 with femoral neck fractures and 117 with intertrochanteric femoral fractures) was conducted, measuring average HU values on preoperative CT.
Statistical Analysis: Statistical comparisons were performed using independent sample t-tests, chi-square tests, and analysis of variance.
Key Findings:
HU values could not distinguish femoral neck fractures from intertrochanteric fractures.
Unstable intertrochanteric fractures had significantly lower HU values than stable ones.
Male patients had significantly higher HU values than females.
HU values showed high specificity (91.89%) but low sensitivity (17.5%) for predicting intertrochanteric fracture stability.
Moderate overall diagnostic performance was indicated (AUC = 0.6764).
Interpretation:
Limitations:
The study is retrospective and may have selection bias.
HU values support a rule-in role rather than general screening.
