The Flow-Nail can also be used to deliver injectable bone void fillers to a surgical site. ## Device Story Flow-Nail is a dynamic compression trochanteric nail system for orthopedic fracture fixation. System components include intramedullary nail, sliding fenestrated lag screw, anti-rotation screws, and cap. Device is used in surgical settings by orthopedic surgeons to stabilize proximal femoral fractures; additionally functions as a conduit for delivery of injectable bone void fillers (BVF) to the surgical site. Mechanical fixation is achieved via standard intramedullary nailing techniques. Clinical benefit includes stabilization of fractures and potential for localized bone void augmentation. Device is manufactured from titanium alloy. ## Clinical Evidence Bench testing only. Mechanical performance demonstrated via static and dynamic compression bending load testing. BVF delivery capability validated through injectability testing, experimental void fill imaging studies, and static extraction torque testing. ## Technological Characteristics Titanium alloy (Ti-6Al-4V) per ASTM F136. System includes intramedullary nail, sliding fenestrated lag screw, anti-rotation screws, and cap. Mechanical fixation principle. No software or electronic components. ## Regulatory Identification An intramedullary fixation rod is a device intended to be implanted that consists of a rod made of alloys such as cobalt-chromium-molybdenum and stainless steel. It is inserted into the medullary (bone marrow) canal of long bones for the fixation of fractures. ## Predicate Devices - Zimmer Natural Nail System ([K120715](/device/K120715.md) and [K091566](/device/K091566.md)) - Stryker Gamma 3 Nail System ([K032244](/device/K032244.md)) - AOS Trochanteric Nail ([K103533](/device/K103533.md) and [K021008](/device/K021008.md)) ## Reference Devices - ETEX Beta-bsm ([K062630](/device/K062630.md), [K072355](/device/K072355.md), [K090242](/device/K090242.md), [K101557](/device/K101557.md)) - CarriGen ([K062630](/device/K062630.md), [K072355](/device/K072355.md), [K090242](/device/K090242.md), [K101557](/device/K101557.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
