Inframammary fold reconstruction has scarcely been evaluated in literature. No biomechanical analyses have been performed comparing different reconstructive methods. This evaluation compares the gold-standard suture reconstruction with an intrarib anchor system (Micro BioComposite SutureTak, Arthrex).
Three analysis groups were compared including 8 Sawbone blocks, 22 embalmed cadaver, and 27 regular cadaver specimens (N = 57). Transient mechanical analysis was performed at 5 N/s using an Instron 5565 test frame.
Ultimate load favored the anchor system (compared with the gold-standard suture) by a factor of 9.8 (P < 0.0001) for the regular cadaver group and a factor of 1.7 (P < 0.038) for the embalmed cadaver group. A similar statistically significant benefit was shown for stiffness and load at 2-mm displacement.
This analysis showed an anchor system to be the biomechanically superior fixation method in terms of ultimate load, fixation stiffness, and displacement at failure when compared with the gold-standard suture method in inframammary fold reconstruction. Because of superior stability in every aspect, an anchor system may be considered for inframammary fold reconstruction.
乳房下皱襞重建在文献中鲜有评估。尚未进行生物力学分析来比较不同的重建方法。本评估将金标准缝合重建与肋骨内锚定系统（Micro BioComposite SutureTak，Arthrex）进行比较。
比较了三个分析组，包括8个Sawbone块、22个防腐尸体和27个正常尸体标本（N = 57）。使用Instron 5565测试框架以5 N/s的速度进行瞬态力学分析。
对于正常尸体组，极限载荷支持锚定系统（与金标准缝合相比）的系数为9.8（P < 0.0001），对于防腐尸体组为1.7（P < 0.038）。在2毫米位移时的刚度和载荷方面也显示出类似的统计学显著优势。
该分析表明，与乳房下皱襞重建中的金标准缝合方法相比，锚定系统在极限载荷、固定刚度和失效时的位移方面是生物力学上更优越的固定方法。由于在各个方面都具有卓越的稳定性，乳房下皱襞重建可考虑使用锚定系统。
