Abstract:
Objective:To determine the best accurate measurement of the lateral femur wall in geriatric patients with intertrochanteric fracture by comparing 3 different methods (X-ray, CT axial scan, and CT 3D reconstruction).Methods:A retrospective study was conducted to analyze the imaging data of 109 patients with intertrochanteric fracture of the femur who had been admitted to Beijing Jishuitan Hospital, Capital Medical University from July 2023 to December 2023. There are 36 males and 73 females with an age of (80.3±9.1) years. The morphology of the femoral intertrochanteric fracture on the affected side was observed, measured, and recorded. It was observed whether the affected femoral trochanter was in a neutral position on the anteroposterior X-ray image of bilateral hip joints. The thickness of the lateral femoral wall was measured on X-ray, CT axial scan, and CT 3D reconstruction images of the bilateral hip joints. The measurements were compared between the 3 methods.Results:The affected femoral trochanter was in a neutral position on the anteroposterior X-ray image of bilateral hip joints in 57 cases [52.3% (57/109)]. The thickness of the lateral wall of the femur measured by X-ray was (29.02±8.06) mm, that by axial CT scan (21.83±8.75) mm, and that by CT 3D reconstruction (31.67±5.92) mm, showing statistically significant differences among the 3 methods ( F=47.368, P<0.001). There was a statistically significant difference in the thickness of the lateral wall of the femur between any 2 measurements ( P<0.05). In measurement of the thickness of the lateral femoral wall, based on CT scan images, the intra-group correlation coefficient between X-ray and CT axial scan images was 0.376, and the intra-group correlation coefficient between CT 3D reconstruction and CT axial scan images was 0.268, both showing poor consistency. Conclusions:Compared with X-ray and CT 3D reconstruction images of the bilateral hip joints, measurement of the thickness of the lateral femur wall on CT axial scan images is more accurate and shows strong operational feasibility. Therefore, CT axial scan has advantages in preoperative evaluation of the thickness of the lateral femur wall.
