Abstract

Suprascapular nerve disorders are a significant yet often underdiagnosed cause of shoulder pain and dysfunction, stemming from the nerve's critical role in shoulder stability and mobility through its innervation of the supraspinatus and infraspinatus muscles. This review explores the anatomy and clinical relevance of the suprascapular nerve, highlighting the need for accurate diagnosis in cases of pain, weakness, or functional impairment that mimic other shoulder conditions. Among diagnostic modalities, ultrasound has become a vital tool, providing real-time imaging to precisely assess nerve compression or damage. Its utility extends to therapy, with recent advancements in ultrasound-guided interventions—such as nerve blocks, corticosteroid injections, and radiofrequency ablation—enabling minimally invasive and targeted treatment for acute and chronic shoulder pain. These techniques not only enhance pain relief but also improve functional outcomes and quality of life. Further research into optimized diagnostic and therapeutic approaches is essential to advance the care of suprascapular nerve disorders.
