Piriformis Syndrome (PS) is an uncommon, controversial neuromuscular disorder that is presumed to be a compression neuropathy of the sciatic nerve at the level of the piriformis muscle (PM). The diagnosis is hampered by a lack of agreed upon clinical criteria and a lack of definitive investigations such as imaging or electrodiagnostic testing. Treatment has focused on stretching, physical therapies, local injections, including botulinum toxin, and surgical management. This article explores the various sources of controversy surrounding piriformis syndrome including diagnosis, investigation and management. We conclude with a proposal for diagnostic criteria which include signs and symptoms, imaging, and response to therapeutic injections.
梨状肌综合征（PS）是一种罕见的、有争议的神经肌肉疾病，被认为是坐骨神经在梨状肌（PM）水平受压引起的神经病变。由于缺乏公认的临床标准和明确的检查（如影像学或电诊断检查），因此诊断受到阻碍。治疗方法主要集中在拉伸、物理治疗、局部注射，包括肉毒毒素和手术治疗。本文探讨了梨状肌综合征诊断、检查和治疗方面存在的各种争议来源。最后，我们提出了一个包括体征和症状、影像学和治疗性注射反应的诊断标准建议。
