Treatment of sacral insufficiency fractures (SIFs) has traditionally been conservative, but several patients have been treated with percutaneous sacroplasty. Unfortunately, in the setting of severe, bilateral SIFs, cement may not withstand shear forces present at the lumbosacral junction, and surgical hardware may not provide adequate fixation in osteoporotic, cancellous bone of the sacrum, leading to eventual pseudarthrosis. Thus, we propose a novel technique in which guidance with CT fluoroscopy allows placement of a transiliosacral bar in conjunction with sacroplasty.
传统上，骶骨不全骨折（SIFs）的治疗是保守的，但已有数例患者接受了经皮骶骨成形术治疗。不幸的是，在严重双侧SIFs的情况下，骨水泥可能无法承受腰骶关节处的剪切力，而手术硬件可能无法在骶骨骨质疏松的松质骨中提供足够的固定，最终导致假关节形成。因此，我们提出一种新技术，即通过CT透视引导，在骶骨成形术的同时放置跨髂骶骨棒。
