Teleflex Medical OEM, in conjunction with researchers at the University of Connecticut, has developed a tough, high-modulus composite with potential for bone fixation. Fabricated from a unidirectional, fibrous PLLA/apatite, the composite exhibits excellent mechanical properties which correlate to those of natural bone while featuring excellent surface bioactivity. The entire composite is bioabsorbable whereby a device made from the composite will gradually be replaced by natural bone tissue at the implantation site. Early studies indicate integration can occur firmly and permanently with the surrounding tissue. In addition, such prepared composites may have the potential to be used to control the release of growth factors to enhance bone cell stimulation.

The alignment of HA on PLLA fibers in a polymer matrix increase the flexural modulus of the composite.
