Summary

由于其解剖学特征,桡神经的深分支很容易在Frohse的拱廊中被压缩。超声引导下针头释放联合皮质类固醇注射是深支桡神经粘连的有效且安全的治疗方法。

Abstract

桡神经(RN)的两个主要分支是深分支(DBRN)和浅分支(SBRN)。RN在肘部分裂成两个主要分支。DBRN在supinator的深层和浅层之间运行。由于其解剖学特征,DBRN可以很容易地在Frohse(AF)的拱廊上压缩。这项工作的重点是1个月前左前臂受伤的42岁男性患者。前臂的多块肌肉(指伸肌、 小指 伸肌和尺 伸肌)在另一家医院缝合。之后,他的左手无名指和小指背屈受限。病人不愿再做手术,因为他在1个月前接受了多块肌肉的缝合手术。超声显示桡神经深支(DBRN)水肿并增厚。DBRN的出口点已经深深地粘附在周围的组织上。为了缓解这种情况,对DBRN进行了超声引导下针头松解加皮质类固醇注射。近3个月后,患者无名指和小指的背侧伸展明显改善(无名指:-10°,小指:-15°)。然后,第二次进行相同的治疗。近1个月后,当手指关节完全伸直时,戒指和小指的背侧伸展正常。超声可以评估DBRN的状况及其与周围组织的关系。超声引导下针头释放联合皮质类固醇注射是DBRN粘连的有效且安全的治疗方法。

Introduction

桡神经 (RN) 在肘部水平分裂为两个主要分支:深分支 (DBRN) 和浅分支 (SBRN)。DBRN 起源于 RN 的主干,位于肱骨1 的外上髁水平。DBRN绕桡骨颈部弯曲,然后穿过后旋肌浅缘的腱弓下方,这被称为Frohse2的拱廊。该解剖部位是前臂34 处 DBRN 最常见的卡压部位。在极少数情况下,DBRN 可以从supinator 5 的入口压缩到出口。DBRN的卡压可引起前臂外背近端疼痛和腕伸肌无力678

当神经受伤时,神经传导检查(NCS)和肌电图(EMG)有时会显示异常结果,表明神经受损。尽管肌电图是一种成熟的方法,并提供有关神经疾病的功能信息,但它缺乏检测与神经相关的解剖学和形态学信息的能力9。除此之外,肌电图在神经损伤的早期阶段的敏感性和特异性不是很高。超声可以很容易地检测到周围神经,并在超声成像中显示它们。许多研究报告了高频超声在诊断周围神经卡压方面的价值5。它作为寻找周围神经的诊断方法具有巨大的潜力。Babaei-Ghazani等人在Frohse拱廊报告了DBRN的超声值,他们得出结论,年龄与DBRN的横截面积(CSA)有关,而身高或性别等其他特征不是1。一些研究报告说,皮质类固醇注射可有效治疗肌肉骨骼疾病1011。然而,到目前为止,还没有关于超声引导下针头释放加在DBRN中注射皮质类固醇治疗粘连的报告。在这里,我们报告了一种无需开放手术即可分离粘连的方法。一名左手无名指和小指背屈受限的男性患者采用这种方法进行治疗。该患者在治疗前1个月左前臂受伤。前臂的多块肌肉(指伸肌、 小指 伸肌和尺 伸肌)在另一家医院缝合。他的DBRN有水肿并增厚,DBRN的出口点深深地粘附在周围组织上。使用US引导下放针和注射DBRN皮质类固醇治疗后,当手指关节完全伸直时,患者环和小指的背部伸展正常。

Protocol

这项研究得到了我院伦理和科学审查委员会的批准。从患者那里获得了书面知情同意。所有治疗程序均由具有10年肌肉骨骼超声干预经验的人员执行。操作员必须对肌肉骨骼解剖学有很好的了解。这里使用的超声波机器在 材料表中 提到,并有一个高频探头。 1. 器械设置和患者准备 输入ID号和患者姓名以保存图像。 使用设备消毒湿巾对…

Representative Results

治疗后1个月,手指关节完全伸直,无名指和小指背侧伸展明显改善(无名指:-15°,小指:-25°)。治疗后3个月,患者复诊DBRN。通过超声评估的DBRN粘连范围与治疗前相比显着减小。无名指和小指的背侧伸展也得到了改善(无名指:-10°,小指:-15°; 图3; 视频 2)。第二次进行相同治疗后1个月,当手指关节完全伸直时,戒指和小指的背部伸展正常(无名指:0°,…

Discussion

近年来,超声已成为评估周围神经卡压的宝贵工具。超声波可用于实时观察神经并提供动态可视化12。卡压的明显超声指标是卡压部位的神经CSA增加1314。其他发现,如低回声质地、神经扁平化和血管增多,也见于卡压性神经病变15

RN 卡压综合征约占非创伤性上肢病变的 0.7%。RN 卡压综合征与?…
