Abstract：
UNASSIGNED: Distal fibula osteoporotic comminuted fractures are challenging to treat and are often treated with periarticular locking plates. This study examined the biomechanical difference between locked plating and dual non-locked one-third tubular plating.
UNASSIGNED: Using an osteoporotic Sawbones fibula model, simulated fracture were fixated with one-third tubular dual plating and locked periarticular plating. The samples were then torqued to failure and peak torque, stiffness, and displacement were recorded.
UNASSIGNED: The peak torque of the dual plating group was found to be statistically higher than the periarticular locked plating group (0.841 Nm and 0.740 Nm respectively; p = 0.024). However overall stiffness calculated at each 10° increment of displacement was noted to have no significant difference between the two constructs.
UNASSIGNED: Dual non-locked plating of distal fibula osteoporotic comminuted fractures is biomechanically equivalent to locked periarticular plating.

摘要：
■腓骨远端骨质疏松性粉碎性骨折治疗具有挑战性，通常使用关节周围锁定钢板治疗。这项研究检查了锁定钢板和双重非锁定三分之一管状钢板之间的生物力学差异。
■使用骨质疏松的Sawbones腓骨模型，模拟骨折用三分之一管状双钢板和锁定关节周围钢板固定。然后将样品扭转至失效和峰值扭矩，刚度,并记录了流离失所情况。
■发现双电镀组的峰值扭矩在统计学上高于关节周围锁定电镀组（分别为0.841Nm和0.740Nm；p=0.024）。然而,注意到在位移的每10°增量处计算的总刚度在两个构造之间没有显著差异。
■腓骨远端骨质疏松性粉碎性骨折的双重非锁定钢板在生物力学上等同于锁定关节周围钢板。
