Abstract

Human dura mater (HDM) allografts have been used extensively as a tissue replacement biomaterial. Yet, little is known about HDM biomechanical behavior, which is partially due to HDM's complex collagen fiber architecture. We used small angle light scattering to quantify HDM collagen fiber architecture to determine optimal specimen selection sites for uniaxial mechanical testing. Our results indicated that tissue specimens aligned with the preferred collagen fiber direction were stronger, stiffer, required a greater amount of energy to break the tissue and were more extensible at the ultimate tensile strength than specimens selected perpendicular to the preferred direction. The development of this tissue selection technique will allow us to more accurately assess HDM mechanical behavior in both the natural and chemically modified state.
