摘要
背景:在不同的外力作用下,踝关节骨折块的数目、移位、关节面的受累情况,关节间隙内骨折碎片的位置情况十分复杂,仅凭X射线平片难以良好显示,轴位二维CT虽然分辨率高、影像无重叠,但缺乏立体感,难以准确、全面评价骨碎片的整体情况。目的:探讨螺旋CT三维重建在踝关节骨折的分型和修复方面的临床价值。方法:对36例踝关节骨折患者进行螺旋CT三维重建,明确踝关节骨折的Danis-Weber分型,并制定内固定方案,选择最佳的手术路径。按Barid-Jackson评定标准评定疗效。结果与结论:螺旋CT三维重建结果显示,36例踝关节骨折患者中B型患者22例(61%),C型患者14例(39%)。治疗效果显示,36例患者中优19例(53%),良13例(36%),可4例(11%),优良率为89%。提示螺旋CT三维重建能够真实反映踝关节骨折的病变情况,对踝关节骨折的分型诊断及治疗具有重要的临床意义。
BACKGROUND：The number,displacement,joint surface of ankle joint fracture and fracture fragments of joint space are very complex under different external forces,which are not well shown by X-ray plain film. Although axial two-dimensional CT has high resolution and no-overlapping image,there is difficulty in accurate and complete evaluation of fracture fragments. OBJECTIVE：To investigate the clinical value of spiral CT three-dimensional reconstruction in classification diagnosis and treatment of ankle joint fracture. METHODS：A total of 36 patients with ankle joint fracture received spiral CT three-dimensional reconstruction. The Danis-Weber classification of ankle joint fracture was diagnosed. According to the results,project of internal fixation was formulated,and the excellent operation way was selected. Curative effect was evaluated according to Barid-Jackson standard. RESULTS AND CONCLUSION：Results of spiral CT three-dimensional reconstruction showed there were 22 type B patients （61%） and 14 type C patients （39%） in 36 patients with ankle joint fracture. The therapeutic effects showed there were 19 excellent patients （53%）,13 good （36%） and 4 fair （11%） in 36 patients with an excellent and good rate of 89%. Spiral CT three-dimensional reconstruction can really reflect the lesions of ankle joint fracture. It has clinical significance in classification diagnosis and treatment of ankle joint fracture.
