Reconstruction plates (RPs) are commonly used in scapular neck fractures (SNFs): however, RPs have many defects. In this study, we evaluated a newly designed scapular neck anatomical locking compression plate (SNALCP).
An SNF finite element model (Miller-type IIB) was constructed. Plates were subsequently implanted into the scapula and fixed with screws that were grouped according to the plate used: SNALCP (A) and RP (B). Finally, loads were applied to record and analyze performance.
Under lateral, anteroposterior, and vertical compression loads, the maximum von Mises stresses on the scapula and implants of group A were smaller than those of group B. There were some differences in stress distribution between the two groups.
SNALCP can effectively reduce the stress of the scapula and implant, making stress distribution more uniform and continuous, and has mechanical conduction advantages. Compared to RP, it provides improved stability and more reliable fixation.
重建钢板（RP）常用于肩胛颈骨折（SNF）：然而，RP 存在许多缺陷。本研究评估了一种新设计的肩胛颈解剖锁定加压钢板（SNALCP）。
构建 SNF 有限元模型（Miller ⅡB 型）。随后将钢板植入肩胛骨并用螺钉固定，根据所使用的钢板将螺钉分组：SNALCP（A）和 RP（B）。最后，施加负载以记录和分析性能。
在侧向、前后和垂直压缩负载下，组 A 肩胛骨和植入物的最大 von Mises 应力小于组 B。两组之间的应力分布存在一些差异。
SNALCP 可有效降低肩胛骨和植入物的应力，使应力分布更加均匀连续，具有机械传导优势。与 RP 相比，它提供了更好的稳定性和更可靠的固定。
