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。

Abstract:

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.
