Abstract: |
Having the most mobility of any major joint, the shoulder has a complex and large network of structures providing stability and movement, linking the upper limb to the trunk. In turn, the structures permitting this large range of motion have a propensity for degenerative conditions and trauma. Interventions in the shoulder region have been performed using anatomic landmarks as well as image guidance with ultrasound (US), fluoroscopy, and computed tomography. Image guidance is typically recommended to avoid the numerous adjacent structures, and US has become an invaluable tool for both diagnostic and therapeutic purposes. US offers several advantages compared to other image modalities, including avoidance of radiation and contrast agents with relative low cost and high accessibility. In addition, US can provide real-time, high-resolution visualization of the needle tip along with important neurovascular structures to avoid any injection-related complications. © 2025 selection and editorial matter, Alan Kaye, Mark Jones, Neal Rakesh, and Amitabh Gulati. |
