Symptomatic hip flexion deformity secondary to iliopsoas spasticity may interfere with gait, impair sitting balance, or contribute to hip subluxation or dislocation. A nonsurgical, minimally invasive technique to ameliorate iliopsoas spasticity is presented. The technique uses intramuscular injections of botulinum A toxin to provide selective neuromuscular blockade of the iliacus or psoas muscles or both. Because of the anatomic location of the target muscles, this technique uses ultrasound guidance for needle placement. Active electromyographic stimulation is used to verify the needle position adjacent to active myoneural interfaces. The authors' experience to date includes the treatment of 28 patients (53 hips). Use of this technique has resulted in improved hip range of motion. No intraoperative or postoperative adverse events or complications have been observed.
继发于髂腰肌痉挛的有症状的髋关节屈曲畸形可能会干扰步态、损害坐位平衡，或导致髋关节半脱位或脱位。本文介绍一种改善髂腰肌痉挛的非手术、微创技术。该技术通过肌内注射A型肉毒杆菌毒素来选择性地对髂肌或腰大肌或两者进行神经肌肉阻滞。由于目标肌肉的解剖位置，该技术使用超声引导进行针头定位。使用主动肌电图刺激来确认针头位于活跃的肌神经界面附近。作者目前的经验包括治疗28例患者（53髋）。使用该技术已使髋关节活动范围得到改善。未观察到术中或术后不良事件或并发症。
