摘要

Pain associated with or in proximity to the coracoid process is an underrecognized condition, characterized by anterior shoulder pain and tenderness over the coracoid apex, distinct from well-known shoulder conditions such as rotator cuff abnormalities. In 2016, Gigante et al. [1] conducted a survey to investigate the prevalence, clinical characteristics, and response to corticosteroid injections for coracoid pain. They enrolled patients with primary anterior shoulder pain localized to the coracoid trigger point, excluding those with signs of other shoulder disorders. Triamcinolone acetonide injections were administered to 15 patients aged 26–66 years, with the majority being women (86.67%). After 15 days, 40% reported complete resolution, while 60% had residual symptoms and received additional injections. The author suggested that the response to landmark-guided corticosteroid injections was suboptimal, underscoring the complexity of pain generators near the coracoid region. Ultrasound imaging allows for a detailed examination of tendons and ligaments attached to the coracoid process, enabling precise targeting for treatment. This chapter will explore the sonoanatomy of structures in the coracoid region, their common pathologies, and considerations for pertinent ultrasound-guided interventions.
