[Introduction to Ultrasound-Guided Musculoskeletal Interventions].

The text is an introduction to six articles on ultrasound-guided musculoskeletal interventions for the major extremity joints. Each article provides a detailed overview of injections for the shoulder, elbow, wrist and hand, hip, knee, ankle, and foot. The text of this manuscript emphasizes general advantages, techniques, and practical considerations of ultrasound guided injections. It highlights the benefits of ultrasound guidance over traditional palpation-based methods, emphasizing improved accuracy, safety, and therapeutic efficacy. Various ultrasound-guided techniques, including in-plane and out-of-plane needle approaches and indirect marking methods, are discussed. Key factors influencing procedural success, such as needle visibility optimization, proper ultrasound settings, and aseptic precautions, are explored in detail. Additionally, the article briefly describes training methods for mastering ultrasound-guided injections.
