Innovative Synthetic Graft for Multilevel Spine Fusion Procedures

The Mastergraft Strip is a biocompatible, osteoconductive, porous implant that allows for bony ingrowth across the graft site while resorbing at a rate consistent with bone healing. It is intended for use in combination with a patient's own bone for fusing multiple cervical levels, and offers the surgeons a bone grafting option that provides a continuous latticework for extended grafting procedures at the posterolateral spine. The strip's broad geometric design maximizes bony surface area contact, and allows for continuous bone growth over large bony gaps. Since it is available in unique lengths, the strip can eliminate the need to utilize multiple units of a synthetic product for a long fusion.

The Mastergraft Strip is made from a combination of medical grade highly purified type I bioresorbable lyophilized collagen and biphasic calcium phosphate ceramic in a 15% hydroxyapatite and 85% b-tricalcium phosphate-formulation. This allows it to readily absorb bone marrow aspirate and heal bone defects. The Mastergraft Strip is a product of Medtronic (Minneapolis, MN, USA; www.medtronic.com) has been approved by the U.S. Food and Drug Administration (FDA), and is supplied sterile in a premixed strip form for single patient use.

"The new Mastergraft Strip provides the flexibility and ease of use that greatly simplifies my operative technique,” said Donald Kucharzyk, M.D., of the Orthopedic, Pediatric, and Spine Institute (Crown Point, IN, USA), one of the surgeons who clinically evaluated the product.
