Abstract

INTRODUCTION

We identify sensory branches of the ulnar nerve-palmar ulnar cutaneous nerve (PUCN), dorsal ulnar cutaneous nerve (DUCN), and superficial sensory branch-using ultrasonography.

METHODS

In 60 forearms of 30 healthy adult volunteers, the origin and size of the PUCN, DUCN, and superficial sensory branch were measured by ultrasonography. The relative pathway of the DUCN to the ulnar styloid process was also investigated.

RESULTS

The PUCN was observed in 47 forearms (78%), and the DUCN was observed in all forearms. Average distances from the pisiform to the origin of the PUCN and DUCN were 11.9 ± 1.4 and 7.0 ± 1.0 cm, respectively. Superficial and deep divisions split 0.9 ± 0.3 cm distal to the pisiform. Cross-sectional areas of the PUCN, DUCN, and superficial sensory branch were 0.3 ± 0.1, 1.5 ± 0.5, and 3.9 ± 1.0 mm , respectively.

DISCUSSION

Sensory branches of the ulnar nerve can be visualized by ultrasonography, helping to differentiate ulnar nerve injury originating at either wrist or elbow. Muscle Nerve 57: 569-573, 2018.

摘要

简介

我们通过超声检查确定了尺神经的感觉支——掌尺侧皮神经（PUCN）、背尺侧皮神经（DUCN）和浅感觉支。

方法

在 30 名健康成年志愿者的 60 个前臂中，通过超声测量了 PUCN、DUCN 和浅感觉支的起点和大小。还研究了 DUCN 相对于尺骨茎突的相对路径。

结果

在 47 个前臂（78%）中观察到了 PUCN，在所有前臂中都观察到了 DUCN。从豌豆骨到 PUCN 和 DUCN 起点的平均距离分别为 11.9±1.4cm 和 7.0±1.0cm。浅、深支在豌豆骨远端 0.9±0.3cm 处分开。PUCN、DUCN 和浅感觉支的横截面积分别为 0.3±0.1mm²、1.5±0.5mm²和 3.9±1.0mm²。
