春立正达弹性髓内针工作原理

弹性髓内针通过从干骺端对称插入两根髓内针，每根针在骨内侧形成三个支撑点，提供四项生物力学稳定性：

抗弯曲稳定性：防止骨折端在受力时发生弯曲变形。

轴向稳定性：保持骨折端的轴向对齐，避免短缩或分离。

横向稳定性：抵抗侧向力，防止骨折端移位。

抗旋转稳定性：防止骨折端在旋转力作用下发生扭转。

春立正达弹性髓内针性能特点

微创性：

闭合置钉，骨折处无需切开，高度符合微创理念，减少手术创伤和出血。

手术切口小，术后护理简便，切口感染等并发症风险低。

生物力学适配性：

三点支撑弹性固定，应力分散，有利于骨痂生长，符合儿童骨骼的生理解剖特点。

允许轻微的生理性弯曲和旋转，这种微动可刺激骨形成，促进骨折愈合。

并发症少：

不累及骨骺板，减少对骨骼生长的影响，降低肢体不等长等并发症风险。

术后关节活动恢复快，感染率低，住院时间短。

取出方便：

骨折愈合后，弹性髓内针可通过简单手术程序取出，不会留下性植入物。

取出过程相对简单，通常不会产生明显风险。

春立正达弹性髓内针适应症

弹性髓内针广泛应用于3至13岁儿童长骨骨折，具体适应症包括：

横形骨折：骨折线与骨骼长轴垂直。

短斜形骨折：骨折线呈短斜角。

螺旋形骨折：骨折线呈螺旋状。

具有骨皮质支持的长斜形骨折：骨折线较长，但有足够的骨皮质支撑。

干骺端闭合性骨折：骨折位于干骺端，且为闭合性损伤。
