The goal of this study is to verify how commercially available pre-contoured superior plates fit on clavicle midshaft fractures.
100 cadaveric clavicles were evaluated by three distinct observers applying the clavicle congruence score and comparing four different 6 to 8-hole pre-contoured anatomic locking-plate systems.
the inter-observer agreement was considered moderate by the percentage agreement and fair by the Fleiss' Kappa, with no significant differences between evaluations. Only 1 of the 8 plates presented an anatomic fit greater than 70%. Long plates (8 holes) presented a poor fit compared to short plates (6 or 7 holes).
the overall evaluation showed that currently-available pre-contoured superior plate systems provide a poor fit on clavicles for midshaft fracture fixations. Long plates present a worse fit compared to short ones.
本研究旨在验证市售预成型上钢板在锁骨中段骨折中的适配性。
通过三位不同观察者应用锁骨贴合评分并比较四种不同的 6 到 8 孔预成型解剖锁定钢板系统，对 100 具尸体锁骨进行评估。
观察者间的一致性通过百分比协议被认为是中度的，通过 Fleiss' Kappa 是公平的，评估之间没有显著差异。只有 1 块 8 孔的钢板呈现出大于 70%的解剖贴合。长钢板（8 孔）与短钢板（6 孔或 7 孔）相比，贴合效果较差。
总体评估表明，目前市售的预成型上钢板系统在锁骨中段骨折固定中提供了较差的贴合效果。长钢板与短钢板相比，贴合效果更差。
