In the past, needle aspirations or injections involving the motor system were always carried out either blind or guided by fluoroscopy. Over the last few years, sonography has begun to offer an interesting alternative. Its advantages are that it is a relatively inexpensive technique, while not emitting ionising radiation and being easily accessible. There has been a great deal of technical progress including high frequency transducers, which have led to performance improvements in terms of both diagnosis and treatment of pathologies of the motor system. Due to these technical advances and to sterile covers for the transducers, it is now possible to visualise and to aspirate or inject into a peripheral joint, a tendon sheath or a bursa with or without effusion. This technique does not require a contrast medium injection because the needle position can be checked directly. Minimally invasive, it allows a number of interventions to be carried out with a very low complication rate since the entire path of the needle is followed using sonography, which means that nerves, vessels and other structures can be avoided because they are visualised directly in real time.
在过去，涉及运动系统的针吸或注射操作要么是盲目进行的，要么是在透视引导下进行的。在过去的几年中，超声检查开始提供了一种有趣的替代方法。它的优点是相对便宜，不发射电离辐射，而且易于获得。技术上取得了很大的进展，包括高频换能器，这在运动系统疾病的诊断和治疗方面都有了性能的提升。由于这些技术进步和换能器的无菌覆盖物，现在可以可视化并抽吸或注射到有或没有积液的外周关节、腱鞘或滑囊中。这项技术不需要注射造影剂，因为可以直接检查针的位置。由于整个针的路径都可以通过超声检查来跟踪，因此该技术具有微创性，可以进行多项干预，且并发症发生率非常低，因为可以直接实时观察到神经、血管和其他结构，从而避免了这些结构。
