This pilot study tested whether FiberWire provides similar protection to steel wire against repair displacement in patella fractures.
Thirteen cadaver knees were cyclically loaded with 10 cycles (0-90° flexion) and fracture displacement was recorded. Fixation methods were also tested in load to failure (>3 mm displacement).
There was no difference between wire types in fracture displacement (1.4 mm ± 0.33 mm vs 1.2 mm ± 0.34 mm, respectively; p = 0.418) or in the load to failure (714.7 N ± 110.9 N vs 744.5 N ± 92.8 N, respectively; p = 0.360).
FiberWire provides similar protection to steel wire against repair displacement after fixation of patellar fractures.
本初步研究旨在测试FiberWire缝线在髌骨骨折修复中防止移位方面是否能提供与钢丝类似的保护作用。
对13具尸体膝关节进行10个周期（0 - 90°屈曲）的循环加载，并记录骨折移位情况。同时也测试了固定方法直至失效负荷（移位>3毫米）。
两种缝线类型在骨折移位（分别为1.4毫米±0.33毫米和1.2毫米±0.34毫米；p = 0.418）或失效负荷（分别为714.7牛±110.9牛和744.5牛±92.8牛；p = 0.360）方面均无差异。
在髌骨骨折固定后，FiberWire缝线在防止修复移位方面能提供与钢丝类似的保护作用。
