Safety and Efficacy of PEEK Intramedullary Nail Fixation System using an Ovine Tibial Fracture Repair Model

摘要

A new polymer composite intramedullary nail fixation implant exhibited excellent safety and biocompatibility as evidenced by a mild tissue reaction, without evidence of obvious adverse effects. Live CT-scans of the ostectomy site and callus width reduction seem to illustrate that the fixation of long-bone diaphyseal defects are better supported by PEEK polymers with a slightly superior healing and improved bone remodeling. PEEK IM nail may represent an improved mode of fixation for healing and remodeling in this model when compared to standard stainless steel IM nails.
