DR跟骨俯卧轴位投照对跟骨骨折临床诊断的价值分析

Analysis of the Value of DR Calcaneal Prone Axial Projection Fracture in Clinical Diagnosis of Calcaneus

目的探讨DR跟骨俯卧轴位投照在跟骨骨折的临床诊断价值。方法对68例跟骨外伤患者分别进行足部正斜位、底部轴位以及跟骨俯卧轴位的DR投照拍片,取得患者的不同部位的DR片图像进行对比分析。结果 68例跟骨外伤患者经过X线或CT扫描确诊为跟骨骨折的有60例,采用足部正斜位DR检查发现跟骨骨折29例,底部轴位DR检查发现跟骨骨折43例,跟骨俯卧轴位DR检查发现跟骨骨折55例。三种轴位的DR检查的跟骨骨折显示率分别为48.3%、71.7%和91.7%;三种轴位DR检查的显示率两两组间比较差异均有统计学意义(P<0.05)。结论跟骨俯卧轴位的DR拍摄具有较高的显示率,可提高跟骨骨折的诊断率,值得临床推广应用。

Objective To investigate the DR calcaneal prone axial projection value in clinical diagnosis of fracture of calcaneus. Methods 68 cases of calcaneal injury patients were foot is oblique, bottom axial and calcaneal prone axial DR projection of films, made in different parts of the DR slice images of patients were analyzed. Results 68 cases of calcaneal injury patients after X-ray or CT scan confirmed the diagnosis of calcaneal fractures in 60 cases, found 29 cases of calcaneal fractures by foot is oblique DR inspection, the bottom axial DR examination revealed 43 cases of calcaneal fractures of calcaneus prone, axial DR examination re-vealed 55 cases of calcaneal fractures. Three kinds of axial DR examination of fractures of the calcaneus showed rates were 48.3%, 71.7%and 91.7%;the three axial DR checking showed that the rate difference between the two groups were statistically significant （P〈0.05）. Conclusion Calcaneal prone axial DR shooting the show rate is high, can improve the diagnosis of calcaneal fracture rate, worthy of clinical application.
