A Novel Distal Biceps Rupture Repair Technique Utilizing a Biocomposite Scaffold.

Abstract

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®.
