Specifically, it is intended for phalangeal fusion and fracture, metacarpal fusion and fracture, carpal fusion and fracture, wrist arthrodesis, Distal radius fractures, olecranon fractures, radial head fractures, humeral condylar fractures, cancellous fractures and osteotomies of the malleolus, ankle fractures, metatarsal osteotomies and correction of hallux valgus. ## Device Story Cannulated NuGen™ FX Screw is a bioabsorbable, threaded bone fixation fastener. Device is composed of poly-L/D-lactide copolymer. It features cannulation to accommodate K-wires (1.2mm or 1.6mm) for precise placement during orthopedic surgery. Available in lengths of 14-70mm and diameters of 3.5mm or 4.5mm, with fully or partly threaded configurations. Used by surgeons in clinical settings to maintain alignment of fractures, osteotomies, or arthrodeses in the upper extremity, ankle, and foot. Device provides mechanical stabilization during bone healing; it is intended to be used alongside external bracing or immobilization. The cannulated design allows for guided insertion over a K-wire, facilitating accurate positioning in cancellous bone. Benefit to patient includes internal fixation without the need for permanent metallic hardware, as the material is bioabsorbable. ## Clinical Evidence Bench testing only. ## Technological Characteristics Material: Poly-L/D-lactide copolymer. Form factor: Cannulated threaded screw. Dimensions: 14-70mm length; 3.5mm (1.2mm cannulation) or 4.5mm (1.6mm cannulation) diameter. Manufacturing: Machining. Sterilization: Same as predicate. Energy source: None (mechanical). ## Regulatory Identification A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system. ## Predicate Devices - Biofix® Bioabsorbable SR-PLLA Threaded Fixation Rod ([K952471](/device/K952471.md)) - Biofix® Bioabsorbable, Threaded, Distal Radius Screw ([K974876](/device/K974876.md)) - Biofix® Bioabsorbable, Threaded, Distal Radius Screw ([K992947](/device/K992947.md)) - SmartScrew™ ([K003077](/device/K003077.md)) - SmartScrew™ ([K012001](/device/K012001.md)) - NuGen™ FX Screw ([K023022](/device/K023022.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
