摘 要：BACKGROUND Ankle fractures are common lesions of the lower *** 40%of ankle fractures affect the posterior malleolus(PM).Historically,PM osteosynthesis was recommended when PM size in X-ray images was greater than 25%of the ***,computed tomography(CT)has been gaining traction in the preoperative evaluation of ankle *** To elucidate the similarity in dimensions and to correlate PM size in X-ray images with the articular surface of the affected tibial plafond in the axial view on CT(AXCT)of a PM *** Eighty-one patients(mean age:39.4±13.5 years)were evaluated(54.3%were male).Two independent examiners measured PM size in profile X-ray images(PMXR)and sagittal CT(SAGCT)*** correlation of the measurements between the examiners and the difference in the PM fragment sizes between the two images were ***,the PM size in PMXR was compared with the surface of the tibial plafond involved in the fracture in AXCT according to the Haraguchi *** The correlation rates between the examiners were 0.93 and 0.94 for PMXR and SAGCT,respectively(PIIII(P0.001).CONCLUSION PM fractures show different sizes using X-ray or CT *** showed a larger PM in the sagittal plane and allowed the visualization of the real dimensions of the tibial plafond surface.
