BiologicsPRESERVE™ Subtalar Distraction Arthrodesis Graft

The PRESERVE™ Subtalar Distraction Arthrodesis Graft is a patent-pending graft designed for use in a Subtalar Joint Distraction Arthrodesis procedure. The Paragon 28® PRESERVE™ Grafts are anatomically contoured, aseptically processed and density matched allografts. The round PRESERVE™ Subtalar Joint Distraction Arthrodesis Graft adds height and a varus or valgus orientation to the subtalar joint as necessary. The primary donor sites for the PRESERVE™ Subtalar Distraction Arthrodesis Graft are the distal femur, talus, patella and femoral calcar to provide strength and dense cancellous bone to this area.

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™ Subtalar Distraction Arthrodesis Grafts. The trials can be rotated in the joint to determine the correct amount of height correction as well as the orientation to place the graft such that the foot is in the appropriate amount of varus or valgus. The trials can determine position both clinically and radiographically before a graft is even opened.
