To present an uncomplicated, reliable technique for bone anchor removal in patients with anchor-related infections or chronic pain.
We removed 17 anchors from 9 patients between 1999 and 2004. The surgical technique used fluoroscopy for localization of the anchors and an orthopedic broken screw removal instrument for resection of the anchor and surrounding bone. Nine patients with bone anchors had been symptomatic with chronic pain and/or wound drainage for a mean of 23.7 months before surgery. After removal, 10 anchors grew positive bacterial cultures. The most common organism was coagulase-negative Staphylococcus. During a mean follow-up period of 6.8 months after hardware removal, 8 of the 9 patients had symptomatic improvement.
Fluoroscopic localization and en bloc resection with a broken screw removal instrument is an effective method of removing symptomatic bone anchors.
介绍一种用于治疗与锚钉相关感染或慢性疼痛患者的简单、可靠的骨锚取出技术。
1999年至2004年间，我们从9例患者身上取出了17枚骨锚。手术技术采用荧光透视定位骨锚，并用骨科断钉取出器械切除骨锚及周围骨质。9例骨锚患者术前有慢性疼痛和/或伤口引流症状，平均持续23.7个月。取出后，10枚骨锚细菌培养呈阳性。最常见的微生物是凝固酶阴性葡萄球菌。在取出内固定装置后的平均随访期6.8个月内，9例患者中有8例症状改善。
荧光透视定位并用断钉取出器械整块切除是取出有症状骨锚的有效方法。
