Brachial plexus injury (BPI) is regarded as one of the most devastating injuries of the upper extremity. Brachial plexus neuropathy can have a high morbidity by seriously affecting the motor function and sensation of upper limbs with loss of activities of daily living. The use of computed tomography myelogram and/or magnetic resonance imaging (MRI) assessing brachial plexus offers valuable details including the location, morphology, and severity of preganglionic and postganglionic injuries during the preoperative period. High-field-strength MRI with specific coil and specialized MRI sequences might be not available in every emergency setting and is time-consuming. Point-of-care ultrasonography (POCUS) comes in handy and offers good image resolution of muscles and nerves that makes early detection of neuromuscular injury possible. Here, we present a case report of BPI that POCUS provides indirect evidence of cervical root injury and expedite time to MRI.
臂丛神经损伤（BPI）被认为是上肢最严重的损伤之一。臂丛神经病变可导致较高的发病率，因为它会严重影响上肢的运动功能和感觉，导致日常生活活动能力丧失。使用计算机断层扫描脊髓造影和/或磁共振成像（MRI）评估臂丛神经，可提供有价值的细节，包括术前节前和节后损伤的位置、形态和严重程度。高场强MRI结合特定线圈和专门的MRI序列，并非在每个急诊情况下都能使用，而且耗时较长。床旁超声检查（POCUS）则很实用，它能提供肌肉和神经的良好图像分辨率，使早期发现神经肌肉损伤成为可能。在此，我们报告一例BPI病例，其中POCUS提供了颈神经根损伤的间接证据，并加快了进行MRI检查的时间。
