目的：梨状肌综合征是一种罕见的神经肌肉疾病，发生于梨状肌压迫或刺激坐骨神经。梨状肌综合征的治疗包括注射到梨状肌周围的坐骨神经。这些侵入性方法已与各种技术一起使用，以增加手术的安全性。计算机断层扫描（CT）引导下注射梨状肌和patients.MATERIAL和METHODS的临床结局：作者提出了10个连续的患者进行CT引导下梨状肌注射3月至2007年12月。三名患者有严重的臀部跌倒史，一名患者在深部肌肉注射后形成臀部脓肿，另一名患者有长时间坐在地毯上的习惯。未确定其他患者的病因。患者的主要抱怨是腿部疼痛和麻木。感觉迟钝是主要的神经系统发现。结果：9例患者在梨状肌注射后症状完全持续恢复。只有在深部肌肉注射后形成臀部脓肿的患者显示出中度改善。另1例患者在梨状肌注射后6个月因椎间盘突出行手术治疗。结论：CT引导下梨状肌注射术是治疗梨状肌综合征安全有效的方法。
AIM: Piriformis syndrome is a rare neuromuscular disorder that occurs when the piriformis muscle compresses or irritates the sciatic nerve. The treatment of piriformis syndrome includes injections into the piriformis muscle around the sciatic nerve. These invasive approaches have been used with various techniques to increase the safety of the procedure. Computed tomography (CT)-guided injection of the piriformis muscle and the clinical outcome of the patients are discussed.MATERIAL and METHODS: The authors presented 10 consecutive patients that underwent CT-guided piriformis injection between March and December 2007. Three patients had a history of a severe fall on the buttocks, one had gluteal abscess formation following deep intramuscular injection, and another one had a habit of prolonged sitting on the carpet. Etiology was not identified in the Other patients. Main complaints of the patients were pain and numbness in the legs. Hypesthesia was the major neurological finding. Magnetic resonance imaging (MRI) and electromyography (EMG) were performed in all patients.RESULTS: Nine patients had full and sustained recovery of their symptoms after piriformis injection. Only the patient who had gluteal abscess formation following deep intramuscular injection showed moderate improvement. Another patient was operated on in the 6th month after piriformis injection due to an extruded disc herniation.CONCLUSION: CT-guided piriformis injection is a safe and effective method in the treatment of piriformis syndrome.
