Piriformis Syndrome (PS) is a neuromuscular condition caused by the entrapment of the sciatic nerve at the level of the piriformis muscle (PM) and can cause significant discomfort and disability. PS is often misdiagnosed due to its overlapping symptoms with other lumbar and sciatic issues and as such, diagnosing PS remains challenging despite recent invasive and non-invasive diagnostic methods. Diagnostic musculoskeletal ultrasound (MSK US) offers a non-invasive, cost-effective alternative for the identification and evaluation of PS, providing dynamic, real-time imaging of the PM and adjacent structures. This article reviews the applications, advantages, and procedural insights of MSK US in the diagnosis of PS, emphasizing its relevance in rehabilitation settings. We discuss the technical aspects of ultrasound use, interpretation of findings, and integration into clinical practice, aiming to enhance the diagnostic accuracy and therapeutic outcomes for patients with suspected PS.
梨状肌综合征（PS）是一种神经肌肉疾病，由坐骨神经在梨状肌（PM）水平受压引起，可导致严重不适和功能障碍。由于PS的症状与其他腰椎和坐骨问题重叠，常被误诊，因此，尽管最近有有创和无创诊断方法，但PS的诊断仍然具有挑战性。诊断性肌肉骨骼超声（MSK US）为PS的识别和评估提供了一种无创、经济有效的替代方法，可对PM和相邻结构进行动态、实时成像。本文综述了MSK US在PS诊断中的应用、优势和操作要点，强调其在康复环境中的相关性。我们讨论了超声使用的技术方面、检查结果的解读以及如何融入临床实践，旨在提高疑似PS患者的诊断准确性和治疗效果。
