在工作中常遇到因胸部外伤引起肋骨骨折病人在复诊时拍片所见与上次诊断不符,骨折部位增多或无骨折,或骨折部位与前次不同,甚至有的几家医院诊断不一致,咎其误诊漏诊的原因,笔者认为,有以下几种。 1.肋骨的形态在投影中容易出现假象,属不规则骨,呈长条形,向前下弯曲呈弓形,在投影上每根肋骨可有轴位、斜位、前后位、后前位。前后数根交错,互相重叠,尤其是身体瘦弱的老年人,腋中线部位较难分辨,若两次投照体位稍有变动,容易出现上述现象。
Frequently encountered at work because of chest trauma rib fractures patients at the referral when the film seen with the previous diagnosis does not match, the fracture site increased or no fracture, or fracture site different from the previous, and even some of the hospital diagnosis is inconsistent, blame the The reasons for misdiagnosis, I believe that there are the following. 1. The shape of ribs in the projection prone to illusion, is an irregular bone, was elongated, bowed forward bowed, each rib in the projection axis, oblique position, anteroposterior position, posterior position. Before and after the number of staggered, overlapping, especially in the elderly with thin, mid-axillary parts more difficult to distinguish, if the two shot a slight body position changes, prone to the above phenomenon.
