Distal biceps tendon ruptures are uncommon injuries that have a re-rupture rate of 1.2% - 6%. In severe traumatic injuries or chronic injuries, a distal biceps tendon repair may require augmentation due to insufficient tissue quality. Unsuccessful treatment of these injuries can result in the loss of approximately 40% of supination strength and 30% of elbow flexion strength. There has been a growing interest in biologic augmentation in orthopedic surgery, and its incorporation into distal biceps tendon repairs has increased as well. Established bio-inductive implants and dermal allografts have been shown to be of benefit; however, these biologics have drawbacks such as failure to incorporate at time of implantation, lack of structural strength, and technical difficulty of implantation. The BioBrace® (ConMed, New Haven, CT) is a bio-inductive, biocomposite scaffold that is composed of highly porous type I collagen and bio-resorbable poly (L-Lactide) (PLLA) microfilaments. It can be used in conjunction with distal biceps tendon repair or reconstruction. It has the advantage of providing strength to the augmented repair at time zero of implantation, while also demonstrating the ability to induce new organized tissue growth throughout its resorptive phase. We describe a technique to successfully augment a distal biceps tendon repair using the BioBrace®.
肱二头肌长头腱远端撕裂较为少见，其再撕裂率为 1.2%-6%。在严重创伤性损伤或慢性损伤中，由于组织质量不足，可能需要对肱二头肌长头腱进行修复增强。这些损伤若治疗不当，可能导致旋后力量丧失约 40%，肘部弯曲力量丧失约 30%。生物增强在骨科手术中的应用日益受到关注，其在肱二头肌长头腱修复中的应用也有所增加。已证实某些生物诱导性植入物和真皮同种异体移植物具有益处；然而，这些生物制剂存在一些缺点，如植入时不能融合、缺乏结构强度以及植入技术困难。BioBrace®（康美，纽黑文，CT）是一种生物诱导性、生物复合材料支架，由高多孔 I 型胶原蛋白和生物可吸收聚（L-丙交酯）（PLLA）微丝组成。它可与肱二头肌长头腱修复或重建联合使用。它的优点是在植入的即刻为增强修复提供强度，同时还具有在吸收阶段诱导新的有组织生长的能力。我们介绍了一种使用 BioBrace®成功增强肱二头肌长头腱修复的技术。
