摘要
目的总结近年来经S_2骶髂(second sacral alar-iliac,S_2AI)螺钉技术用于脊柱骨盆稳定性重建方面的研究进展。方法查阅近年国内外关于S_2AI螺钉技术应用于脊柱骨盆稳定性重建方面的研究报道,对S_2AI螺钉技术的发展历程、临床应用及其相关的解剖学、影像学及生物力学等方面进行分析总结。结果 S_2AI螺钉技术作为一种新的临床脊柱骨盆稳定性重建方式,不仅取得令人满意的腰骶间稳定效果,同时也克服了传统髂骨螺钉钉尾端突出皮肤等相关并发症的问题。由于S_2AI螺钉的钉道更加狭窄,所以增加了徒手植钉操作上的难度。虽然S_2AI螺钉是穿透3层皮质固定,但生物力学试验结果显示,传统髂骨螺钉与S_2AI螺钉在固定骶髂关节稳定性力学性能上无明显差异。结论在脊柱骨盆稳定性重建上,S_2AI螺钉技术可作为一种替代传统髂骨螺钉技术的相对安全可靠的选择。
Objective To summarize the current research progress of second sacral alar-iliac（S2AI） screw technique for reconstruction of spinopelvic stability. Methods The recent original literature concerning development,clinical applications, anatomy, imageology, and biomechanics of S2AI screw technique in reconstruction of spinopelvic stability was reviewed and analyzed. Results As a common clinical strategy for the reconstruction of spinopelvic stability, S2AI screws achieve satisfactory effectiveness of lumbosacral fixation without complications which were found during the application of traditional iliac screws technique. S2AI screw technique is more difficult to place screws by hand because of its narrow screw trajectory. Although the S2AI screws trajectory pass through 3 layers of bone cortex, the biomechanical cadaveric study demonstrate that no statistical difference in stiffness was found between the traditional iliac and S2AI screw in a spinopelvic fixation model. Conclusion S2AI screw technique should be a safe and feasible method for reconstruction of spinopelvic stability in place of the traditional iliac screw technique.
