目的:虽然锁骨钩钢板在骨和肩关节功能方面表现出良好的结果,他们的设计可能会导致并发症,由于压力集中在板的尖端。本研究旨在探讨不同钩植入角度对钩板与肩峰接触面面积的影响,以最小化失配和最大化接触表面积为目标。
方法:本研究纳入了20具肩部柔软的尸体,并根据钩植入角度在不同位置测量钩板的接触表面积。
结果:结果显示兼容性不同,宽度,和接触表面区域的长度取决于钩植入角度和内侧或外侧行放置。侧行通常表现出优异的兼容性(84.0%vs46.67%,p值<0.001),接触面积较宽(3.55±0.08mmvs3.09±0.10mm,p值=0.004)和较长的接触面积(7.36±0.19mmvs5.10±0.23mm,p值<0.001)在特定角度。对横向位置的详细分析表明,零角度的注入导致最大的接触表面积,宽度为3.91±0.70mm(p值=0.083),长度为8.85±1.24mm(p值<0.001)。
结论:根据钩植入角度将钩横向放置并放置在零位置,可以使接触表面积最大化,可以减少应力集中,减少钩钢板固定的并发症。需要进一步研究和考虑解剖变化,以完善放置技术并提高患者预后。
方法:V级证据。
OBJECTIVE: While Clavicle hook plates have demonstrated favorable results regarding bone and shoulder function, their design can potentially lead to complications due to pressure concentration at the plate\'s tip. This study aims to investigate the impact of different hook implantation angles on the contact surface area between the hook plate and acromion, with the goal of minimizing mismatch and maximizing contact surface area.
METHODS: Twenty soft shoulder cadavers were included in the study, and the contact surface area of the hook plate was measured in different positions based on the hook implantation angle.
RESULTS: The results showed variations in compatibility, width, and length of the contact surface area depending on the hook implantation angle and the medial or lateral row placement. The lateral row generally demonstrated superior compatibility (84.0% vs 46.67%, p-value < 0.001), with a broader contact area (3.55 ± 0.08 mm vs 3.09 ± 0.10 mm, p-value = 0.004) and a longer contact area (7.36 ± 0.19 mm vs 5.10 ± 0.23 mm, p-value < 0.001) at specific angles. A detailed analysis of the lateral position revealed that the zero angle of implantation resulted in the greatest contact surface area, measuring 3.91 ± 0.70 mm in width (p value = 0.083) and 8.85 ± 1.24 mm in length (p value < 0.001).
CONCLUSIONS: Placing the hook laterally and at the zero position according to the hook implantation angle can maximize contact surface area, may reduce stress concentration, and minimize complications in hook plate fixation. Further research and consideration of anatomical variations are warranted to refine the placement technique and enhance patient outcomes.
METHODS: Level V evidence.
