جاگذاری پیچ ایلیوساکرال زیر کنترل سی تی اسکن با بیحسی موضعی

Ilio-sacral screw is a technique for posterior pelvic fixation. In spite of its benefits, it had not performed commonly in Iran because of its difficulties. We changed this technique to insert the screw under CT-Scan guide with lical anesthesia to increase image quality and decrease neurological complications and performed it in two patients. In both cases the screws were inserted in correct position without any complication.
