The surgeon’s real dose exposure during balloon kyphoplasty procedure and evaluation of the cement delivery system: a prospective study

摘要

PurposeBalloon kyphoplasty is currently widely used for the treatment of vertebral compression fractures (VCFs). Procedure safety is directly linked to precise radiological imaging generated by various X-ray systems (C-arm, O-arm^®, angiography table, etc.). This minimally invasive spinal surgery is, by definition, associated with significant radiation exposure for both patient and surgeon. Real dose exposure received by the surgeon is usually difficult to precisely record. In our center, all Balloon Kyphoplasty Procedures (BKP) are now performed using an O-arm^® image guidance system to control cement augmentation in VCF. Our preliminary experience described reduced dose exposure compared to C-arm guided procedures. We present here an additional way to considerably reduce the amount of radiation received by the surgeon during BKP using a new injection system.
