HammerGraft™ Hammertoe System
The PRESERVE™ HammerGraft implant is a minimally manipulated, aseptically
processed allograft designed specifically for fixation of hammertoe fusions.
The HammerGraft implant is composed of cortical bone harvested from the tibia
to meet the strength requirements of the proximal interphalangeal joint,
while being sized to fit in the medullary canal.
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 of the graft.
Further, hydrogen peroxide is avoided during processing with the intent
to help preserve osteoinductivity.
Straight and angled configurations of the HammerGraft implants are available in
2.3mm and 2.8mm diameters.
The implants are packaged in a hydration solution and may be used immediately
out of the package without requiring reconstitution.
Paragon 28®'s Design Rationale
The HammerGraft is an aseptically processed cortical bone graft designed with
rotational stability and ease of insertion in mind.
The rib height of the implant and drill diameter for bone preparation were
optimized to ensure maximum pull-out strength while minimizing any plastic
deformation to surrounding cancellous bone upon insertion of the HammerGraft implant.1
