Fixation of osteoporotic proximal humerus fractures remains challenging even with state-of-the-art locking plates. Despite the demonstrated biomechanical benefit of screw tip augmentation with bone cement, the clinical findings have remained unclear, potentially as the optimal augmentation combinations are unknown. The aim of this study was to systematically evaluate the biomechanical benefits of the augmentation options in a humeral locking plate using finite element analysis (FEA).

基于经过验证的参数计算模型，骨距螺钉的水泥增强可以最大程度地降低预测的肱骨近端钢板切除螺钉的风险：增强肱骨近端骨折钢板。

即使使用最先进的锁定钢板，骨质疏松性肱骨近端骨折的固定仍然具有挑战性。尽管已证明用骨水泥增强螺钉尖端的生物力学益处，但临床发现仍不清楚，可能是因为最佳增强组合尚不清楚。本研究的目的是使用有限元分析 (FEA) 系统地评估肱骨锁定钢板中增强选项的生物力学益处。
