Autogenous bone graft remains the most effective treatment for fracture non unions, pseudoarthroses and for optimizing the success rate of arthrodesis. It is safer and more effective than artificial hydroxyapatite materials or allograft. The Acumed bone graft harvesting instruments facilitates safe, rapid harvest of morsellized autogenous graft through a small skin incision which minimizes the … Read more
