摘要
目的:探讨跟骨双45°斜轴位DR摄片在跟骨骨折中的诊断价值。方法:对52例跟踝部外伤患者分别行足部正位和斜位、跟骨侧位和轴位DR摄片及跟骨双45°斜轴位DR片,取得跟骨不同部位骨质图像,进行对比分析。结果:52例跟踝部外伤患者经X线片或CT检查发现证实跟骨骨折46例,其中足部正斜位发现跟骨骨折21例;跟骨侧轴位片共发现骨折30例;跟骨侧轴位加双45°斜轴位摄片发现跟骨骨折42例,与跟骨侧轴位片相比,分别多发现跟骨前突骨折3例及跟骨结节内外侧突骨折6例。各个摄片方法对跟骨骨折的显示率分别为45%、65%和91%。结论:跟骨侧轴位加拍双侧45°斜轴位DR摄片能明显提高跟骨骨折诊断率,尤其是对跟骨结节内外侧突及跟骨前部近跟距关节处骨折具有较高的诊断价值。
Objective：To explore the clinical value of double 45° oblique-axial view of calcaneus DR in the diagnosis of calcaneus fracture.Methods：Rantine dorsoplantar and oblique view of foot,lateral and axial view of calcaneus and double 45° oblique-axial view of calcaneus DR were used to examine 52 patients with ankle injury,the acquired images were compared and analyzed.Results：There were 46 cases of calcaneus fracture found by X-ray and CT examination,among which 21 cases could be found on dorsoplantar and oblique view,30 cases on lateral and axial view,42 cases were found by double 45° oblique-axial view on DR.Compared with lateral and axial view of calcaneus,3 more fractures near calcaneo-astragalar joint and 6 more fractures near posterior brim of calcaneus were found by double 45° oblique-axial view on DR.The rates of fractures shown by dorso-plantar and oblique view of foot,by lateral and axial view of calcaneus,and by double 45° oblique-axial view on DR were 45%,65% and 91% respectively.Conclusion：Lateral and axial view of calcaneus combined with double 45° oblique-axial view on DR has obvious value in detecting calcaneus fractures,especially fractures of posterior brim and near the calcaneo-astragalar joint.
