【摘要】：目的比较X线正、侧、斜位及CT扫描对成人桡骨头细微骨折的检出率。方法回顾性分析26例桡骨头细微骨折的X线和CT图像。分别统计肘关节正、侧、斜位和CT扫描对桡骨头细微骨折的检出率并进行比较。结果 26例桡骨头细微骨折首次检出例数:正位0例、侧位0例、斜位19例(73.1%),CT 23例(88.5%)。骨折检出率斜位和CT均优于正、侧位(χ2=29.94,P㩳0.05;χ2=41.24,P㩳0.05),斜位与CT检出率差异无统计学意义(χ2=1.981,P0.05);2~4周后复查骨折检出例数:正位18例(69.2%),侧位16例(61.5%)、斜位26例(100%),CT 26例(100%)。斜位与CT检出率均优于正、侧位(P㩳0.05)。复查后正、侧位、斜位检出率均高于首次检出率(P㩳0.05),复查前、后CT检出率差异无统计学意义(P0.05)。结论斜位投照和CT检查对桡骨头细微骨折具有极高的检出率,2~4周后复查是提高常规肘关节正、侧位及斜位片检出率的可靠方法,斜位片一定程度上可替代CT作为诊断桡骨头细微骨折的首选方法。
[Abstract]:Objective to compare the positive, lateral, oblique and CT scans in the detection of minor fractures of the radial head in adults. Methods the X-ray and CT images of 26 cases of minor fractures of the radial head were retrospectively analyzed. Results 26 cases of radial head minor fractures were detected for the first time: positive position 0 cases, lateral position 0 cases, oblique position 19 cases 73.1% CT 23 cases. The detection rate of fracture in oblique position and CT scan was better than that in CT. Lateral position (蠂 2, 29.94 P? 0. 05; 蠂 2: 41.24? There was no significant difference between the positive rate of oblique position and that of CT (蠂 ~ (2) 1. 981 ~ (1) P 0.05 ~ 2 ~ 2 weeks later): 18 cases of positive position (69.2%), 16 cases of lateral position (61.5%), 26 cases of oblique position (26 cases) and 26 cases (26 cases) of oblique position were superior to positive position (P < 0.05), and the detection rate of lateral position was better than that of lateral position (P < 0.05). There was no significant difference in the detection rate between oblique position and CT (蠂 ~ (2)). The positive, lateral and oblique detection rates were higher than those in the first positive, lateral and oblique position after reexamination. There was no significant difference in the detection rate of posterior CT before and after reexamination (P 0.05). Conclusion oblique radiography and CT examination are reliable methods to improve the positive, lateral and oblique radiographs of the elbow joint after 4 weeks. Oblique radiography can replace CT as the first choice for the diagnosis of radial head fracture.
