【摘要】：目的分析CT图像后处理技术结合MRI检查在老年踝关节骨折分型诊断和预后评估中的应用。方法回顾性分析68例的老年踝关节骨折患者临床资料,分别对患者进行CT及MRI检查,分析患者骨折位置与区域、骨折分型和分度情况,关节韧带经CT图像后处理的显示结果,利用CT图像后处理与MRI技术评估患者术后并发症及预后。结果患者的骨折位置中,发生在左踝与右踝的比例无统计学差异(P0.05)。而在骨折区域上,发生在内踝与外踝的比例明显高于发生于后踝的比例(P0.05);患者的骨折分型之间并无明显差异(P0.05),但骨折分度为Ⅰ度、Ⅱ度及Ⅲ度的比例均明显高于Ⅳ度者(P0.05);CT图像后处理技术对于不同分型骨折患者关节韧带的显示率无统计学差异(P0.05);50例需手术治疗的患者中,经CT图像后处理与MRI技术评估发现,并发症预后为优的比例为50.00%(25/50),良为36.00%(18/50),差为14.00%(7/50)。预估患者术后发生创伤性关节炎的比例为8.00%(4/50),与随访6个月后的实际发生率4.00%(2/50)相比无统计学差异(P0.05)。结论 CT图像后处理结合MRI技术对老年踝关节骨折患者进行分型诊断和预后评估效果较好,准确率较高。
[Abstract]:Objective to analyze the application of CT image post-processing combined with MRI in the diagnosis and prognosis evaluation of senile ankle fracture.Methods the clinical data of 68 elderly patients with ankle fracture were analyzed retrospectively. Ct and MRI examinations were performed respectively. The location and area of fracture, the classification and grading of fracture, and the display of joint ligament after CT image processing were analyzed.Postoperative complications and prognosis were evaluated by CT image post-processing and MRI technique.Results there was no significant difference in the ratio of left malleolus and right malleolus in the fracture position of the patients (P 0.05).In the fracture area, the ratio of medial malleolus to lateral malleolus was significantly higher than that of posterior malleolus.The ratio of degree 鈪，
