The PRESERVE™ Cotton Plantarflexing Osteotomy Graft is a patented wedge designed for use in a Cotton Osteotomy. The Paragon 28® PRESERVE™ Grafts are anatomically contoured, aseptically processed and density matched allografts. The anatomic contour of the Cotton Plantarflexing Osteotomy graft features a dorsal to plantar taper with a rounded medial edge to match the contour of the medial cuneiform. The primary donor sites for the PRESERVE™ Cotton Plantarflexing Osteotomy Graft are the patella, talus and femoral calcar to provide strength to an area subject to high compressive loads.
All Paragon 28® PRESERVE™ Grafts are aseptically processed, allowing for maintenance of structural integrity and biocompatibility of the graft. Gamma irradiation is not used during processing in order to help avoid structural fatigue and crumbling of the graft. Further, hydrogen peroxide is avoided during processing with the intent to help preserve osteoinductivity of the graft.
A set of trials are available for use with the PRESERVE™ Cotton Osteotomy Grafts. The trials are sized matched to the grafts to determine the correct amount of correction both clinically and radiographically before a graft is even opened.
