Percutaneous Repair of a Nonunion Pubic Ramus Fracture Using a Metallic Stent Scaffold and Cement Osteoplasty

This report describes a case of repair of a nonunion pubic ramus fracture with intramedullary placement of a self-expanding nitinol stent across a fracture gap to provide a permeable scaffold for polymethylmethacrylate (PMMA) cement to track across the fracture gap and to restrict leakage into surrounding soft tissues. The patient presented with an 8-month history of pelvic pain and debility. His pain remains resolved after 14 months. Percutaneous repair of nonunion pubic rami fractures using a bridging metallic stent in combination with PMMA bone cement may be an effective treatment for these fractures.
