【摘要】：目的探讨超声在少见桡神经损伤中的定位诊断价值。方法对7例上臂桡神经缩窄和5例骨间后神经损伤的患者进行超声检查,分析其超声声像图特征,并与临床外科手术进行对照。结果超声可清晰显示上肢桡神经束的走行及内部结构。12例患者中7例超声定位病变于上臂桡神经束,5例病变定位于前臂的骨间后神经,声像图表现为神经走行粗细不均,局部缩窄变细、两端神经束增粗,内部条索束膜结构消失,回声减低,外膜回声增强。超声定位和损伤处形态评估与术中发现一致。结论术前超声检查可明确上臂桡神经卡压及骨间后神经损伤,确定缩窄病灶位置及神经形态变化,对指导手术方案制定及评估预后有重要价值。
[Abstract]:Objective to evaluate the value of ultrasound in the diagnosis of rare radial nerve injuries. Methods Ultrasonography was performed in 7 cases of radial nerve constriction in the upper arm and 5 cases of posterior interosseous nerve injury. Results Ultrasound could clearly show the radial nerve bundle of upper extremity and internal structure of 12 patients. 7 cases were located in the radial nerve bundle of upper arm by ultrasound. The lesions were located in the posterior interosseous nerve of the forearm in 5 cases. The sonogram showed that the nerve walked unevenly, the local narrowing became thin, the nerve bundles at both ends became thicker, the membrane structure of the internal stripe bundle disappeared, and the echo decreased. Echo enhancement of adventitia. The location and morphological evaluation of injury were consistent with those found during operation. Conclusion preoperative ultrasound examination can identify the compression of the radial nerve in the upper arm and the injury of the posterior interosseous nerve, and determine the location of the condensed focus and the changes of the nerve morphology. It has important value in guiding the operation plan and evaluating the prognosis.
