高频超声在隐匿性肋骨骨折诊断中的应用价值

目的探讨高频超声在隐匿性肋骨骨折诊断中的应用价值。方法对42例有胸部外伤史、临床表现及体征均怀疑肋骨骨折的患者同时行高频超声及X线检查，分析高频超声及X线对肋骨骨折的检出情况。结果42例患者通过多次超声及X光片复查最终确诊均有不同程度肋骨骨折，其中高频超声初次检查发现39例患者有肋骨骨折及软组织损伤情况，检出率为93％，骨折断端错位0．5～5．5mm，检出X线胸片未查出的7例骨折；经x线初次检查发现肋骨骨折32例，检出率为82％，骨折断端错位2．0～5．5mm，检出高频超声未查出的骨折1例。两者对肋骨骨折检出率的比较具有高度统计学意义（P〈0．01）。结论高频超声能检出X线检查不能显示的轻微肋骨骨折，对隐匿性肋骨骨折的检出具有重要的临床应用价值。

The clinical application value of high frequency ultrasound in the diagnosis of occult costal fracture

Objective To investigate the value of the high frequency ultrasound on diagnosing occult rib fractures.Methods Forty-two patients of chest trauma history of suspected fractured ribs because of their Symptoms and Signs had been given the examinations of the high frequency ultrasound and X-ray,and the fractured ribs detection results of the high frequency ultrasound and X-ray had been analysed.Results Forty-two patients had been diagnosed with varying degrees of rib fractures through the review of the high frequency ultrasound and X-ray.39 patients had been detected rib fractures and soft tissue injury by the high frequency ultrasound in the initial examination,and the detection rate was 93%.The distance of disruption displacement was 0.5 mm to 5.5 mm,and 7 patients that had been not detected by X-ray had been detected by the high frequency ultrasound.32 patients had been detected rib fractures by X-ray in the initial examination,and the detection rate was 82%.The distance of disruption displacement was 2.0 mm to 5.5 mm,and 1 patient that had been not detected by the high frequency ultrasound had been detected by X-ray.There was difference between the high frequency ultrasound and X-ray in the detection rate of fractured ribs(P < 0.01).Conclusion The slight fractured ribs that can not been detected by X-ray can been detected by the high frequency ultrasound.The high frequency ultrasound is very important clinical value of the high frequency ultrasound on diagnosing occult rib fractures.
