(A) Top: 6 mm diameter bone cores from trabecular bone of bovine distal femur. Bottom: Deculluarlized bone cores using a hypotonic and detergent. (B) Bone plugs placed in to Tygon® tubing and clamped at each end (C) Collagen injection molded into Tygon® tubing. (D) Final construct with fiber direction axis labels. Fibers formed along the x-axis in the longitudinal direction or along the y-axis in the radial direction. Double sided arrows on the right indicate interface region where collagen penetrated into the trabecular bone.
