Given the proposed mechanism of failure in maximal repair at the suture-tendon interface and the inherent inferior quality of cuff tissue in large and massive rotator cuff tears, a solution providing both strength and improved cuff biology remains the main goal in preventing retears and allowing enhanced rehabilitation to restore cuff muscle strength. This has led to graft-based approaches for reconstruction in shoulder repair, including bridging reconstruction. Biocomposite grafts encourage new tissue formation but lack structural support, while human dermal allografts provide structural support but fall short in tendon integration. Thus, a biocomposite scaffold is introduced to combat these limitations. In this technique, we describe placing the BioBrace graft (Biorez), eliminating tension at the graft-suture interface, providing strength and tissue integration.
鉴于在缝线-肌腱界面进行最大程度修复时所提出的失效机制,以及大型和巨大型肩袖撕裂中袖带组织固有的较差质量,提供强度并改善袖带生物学特性的解决方案仍然是预防再撕裂并允许加强康复以恢复袖带肌肉力量的主要目标。这导致了基于移植物的肩部修复重建方法,包括桥接重建。生物复合材料移植物可促进新组织形成,但缺乏结构支撑,而人同种异体真皮移植物提供结构支撑,但在肌腱整合方面存在不足。因此,引入了一种生物复合支架来克服这些局限性。在这项技术中,我们描述了放置BioBrace移植物(Biorez),消除移植物-缝线界面的张力,提供强度和组织整合。
