BACKGROUND Incomplete lateral compression fractures (including AO Type B2.1) are among the most common pelvic ring injuries. Although the treatment of choice remains controversial, sacroiliac (SI) screws are commonly used for the operative treatment of incomplete lateral compression fractures of the pelvic ring. However, the disadvantages of SI screws include the risk of nerve root or blood vessel injury. Recently, tape sutures have been found useful as stabilizing material for the treatment of injuries of the syndesmosis, the rotator cuff and knee ligaments. In this current study, we aimed to test the biomechanical feasibility of tape sutures to stabilize the pelvis in the setting of AO Type B2.1 injury. METHODS Six human cadaveric pelvises underwent cyclic loading to compare the biomechanical stability of different osteosynthesis methods in a B2.1 fracture model. The methods tested in this experiment were a FiberTape® suture and the currently established SI screw. A 3D ultrasound tracking system was used to measure fracture fragment motion. Linear regression was used to model displacement and stiffness at the posterior and anterior pelvic ring. RESULTS At the posterior fracture site, the FiberTape® demonstrated similar displacement (2.2 ± 0.8 mm) and stiffness (52.2 ± 18.0 N/mm) compared to the sacroiliac screw (displacement 2.1 ± 0.6 mm, P >  0.999; stiffness 50.8 ± 13.0 N/mm, P > 0.999). Considering the anterior fracture site, the FiberTape® again demonstrated similar displacement (3.8 ± 1.3 mm) and stiffness (29.5 ± 9.0 N/mm) compared to the sacroiliac screw (displacement 2.9 ± 0.8 mm, P = 0.2196; stiffness 37.5 ± 11.5 N/mm, P = 0.0711). CONCLUSION The newly presented osteosynthesis, the FiberTape®, shows promising results for the stabilization of the posterior pelvic ring in AO Type B2.1 lateral compression fractures compared to a sacroiliac screw osteosynthesis based on its minimal-invasiveness and the statistically similar biomechanical properties.

胶带缝合术可稳定不完整的骨盆后环骨折-生物力学分析一种新的微创治疗不完全的侧压骨盆环骨折的方法。

背景技术不完全的侧向压缩性骨折（包括AO B2.1型）是最常见的骨盆环损伤。尽管选择的治疗方法仍存在争议，但sa骨（SI）螺钉通常用于手术治疗骨盆环不完整的侧向压缩性骨折。但是，SI螺钉的缺点包括神经根或血管受伤的风险。最近，发现带状缝合线可用作稳定材料，用于治疗椎间盘突出症，肩袖和膝关节韧带的损伤。在本研究中，我们旨在测试胶带缝合在AO B2.1型损伤中稳定骨盆的生物力学可行性。方法对六只人体尸体骨盆进行循环载荷，以比较B2.1骨折模型中不同骨合成方法的生物力学稳定性。在本实验中测试的方法是FiberTape®缝合线和当前建立的SI螺钉。3D超声跟踪系统用于测量骨折碎片运动。线性回归被用来模拟骨盆后环和前骨盆环的位移和刚度。结果与Ta骨螺钉（位移2.1±0.6 mm，P> 0.999；刚度50.8±13.0 N）相比，FiberTape®在后部骨折部位表现出相似的位移（2.2±0.8 mm）和刚度（52.2±18.0 N / mm）。 / mm，P> 0.999）。考虑到前部骨折部位，FiberTape®再次表现出相似的位移（3.8±1.3 mm）和刚度（29.5±9）。0 N / mm）与compared骨螺钉相比（位移2.9±0.8 mm，P = 0.2196;刚度37.5±11.5 N / mm，P = 0.0711）。结论与presented骨螺钉人工合成相比，基于presented骨微创技术和统计学上相似的生物力学特性，与presented骨螺钉合成相比，新近提出的骨合成FiberTape®在AO B2.1型侧向压缩性骨折中显示了后骨盆环稳定的有希望的结果。
