Abstract

Aim: A precise preoperative evaluation of anatomy injuries of intertrochanteric fractures is crucial for surgical planning. Subjects ànd methods: including 101 patients with intertrochanteric fracture  were classified anatomical lesions based on X-rays according to AO classification and Etsuo classified based on 3D CT images. The evaluation of concordance rate between the AO classification based on X-rays  and  the Etsuo classification base on 3D CT images. Results: The study results showed that there are 3 main fracture lines for intertrochanteric fracture : the anterio fracture line was in 101 cases (100%), the posterio fracture line was in 92 cases (91.09%), and the broken line outside wasin 53 cases (52.47%). Classification according to Etsuo includes: 2-part fracture, 19,80%, 3-part fracture 72.28% and 4-part fracture 7.92%. bone accounts for the highest percentage (41.10%). In 41 cases of 2-part fractures on conventional radiographs, on 3D CT revealed 21 cases of 3-part fractures. The study results showed that there is a lowconcordance rate between the  AO base on X-rays and Etsuo base on with K = 0.405. Conclusion: Classification of intertrochanteric fracture  based on X-ray films has limited accuracy. CT scans with 3 D rendering were shown to be more accurate due to more complete detection of fracture locations, morphology and number of fragments.
