The suprascapular nerve is a crucial peripheral nerve originating from the brachial plexus, specifically the upper trunk (C5-C6). It plays a vital role in shoulder function, innervating the supraspinatus and infraspinatus muscles, which are essential for arm elevation and external rotation. Damage to this nerve can lead to pain, weakness, and atrophy in the shoulder, significantly impacting mobility.
In medical ultrasound, the suprascapular nerve is increasingly targeted for diagnostic and therapeutic purposes. Ultrasound guidance allows for precise visualization during nerve blocks for chronic shoulder pain, or for identifying nerve entrapment syndromes, such as at the suprascapular notch or spinoglenoid notch. This non-invasive imaging enhances diagnostic accuracy and optimizes interventional procedures.
