肘关节恐怖三联征,就是这么恐怖!

2017-02-26 佚名 医学界

肘关节后脱位同时伴有尺骨冠状突骨折和桡骨头骨折,称为“肘部严重损伤三联征( terrible triad of the elbow) ”。这是肘部严重的高能量创伤, 由施加于上肢纵轴方向的压缩和剪切暴力引起, 坠落和车祸是常见原因。除了三联损伤外,还常伴有肘内、外侧副韧带和前臂骨间膜的撕裂, 桡骨和(或) 尺骨的骨折, 下尺桡关节分离等。因此整个肘部和前臂显得十分不稳定。肘关节是一个包含肱尺关节(

肘关节后脱位同时伴有尺骨冠状突骨折和桡骨头骨折,称为“肘部严重损伤三联征( terrible triad of the elbow) ”。这是肘部严重的高能量创伤, 由施加于上肢纵轴方向的压缩和剪切暴力引起, 坠落和车祸是常见原因。除了三联损伤外,还常伴有肘内、外侧副韧带和前臂骨间膜的撕裂, 桡骨和(或) 尺骨的骨折, 下尺桡关节分离等。因此整个肘部和前臂显得十分不稳定。



肘关节是一个包含肱尺关节(肱骨滑车—尺骨滑车凹) 、肱桡关节(肱骨头—桡骨头凹) 和上尺桡关节的复合关节,以肱尺关节对肘关节的稳定性最重要。同时, 肘关节囊、侧副韧带和肌肉对维持关节的稳定亦有重要作用。肘关节后脱位主要发生在肱骨滑车与尺骨滑车凹之间。

损伤机制

肘关节在近伸直位,遭受轴向高能量的压缩剪切暴力,导致肘部损伤恐怖三联征。

轴向高能量的压缩剪切暴力,先使桡骨头撞击肱骨小头发生桡骨头的骨折,继续造成冠状突的骨折,再引起肘关节的后脱位和肌腱、韧带的损伤。

冠状突骨折块的大小与肘关节的伸直程度有明确的关系。

冠状突骨折

Regan和Morrey分型:

Ⅰ型:冠突尖部骨折 (骨折块高度<10%冠突高度 )

Ⅱ型:冠突体部骨折(骨折块高度10%-50%冠突高度)

Ⅲ型:冠突基底骨折(骨折块高度>50%冠突高度)

桡骨头骨折

Mason分型:

I型: 桡骨头边缘小片骨折(<25% )。

II型: 桡骨头部分骨折,能够重

III型: 桡骨头完全骨折,不能重建。

IV型: 桡骨头完全骨折,伴肘关节脱位。

肘关节置换在早期是被用于肘关节晚期关节炎的患者,取得了良好疗效,因此也用于老年复杂粉碎肱骨远端骨折,其治疗效果可以等同于或超过切开复位内固定的治疗效果。但是由于肘部软组织覆盖较差、而且大多为高分级的开放性骨折,对于老年肱骨远端骨折患者肘关节置换手术比较复杂,从理论上讲,对于开放性骨折,关节置换增加了切口和深部感染的风险。 美国的学者Michael S. Linn在老年开放性肱骨远端中采用
