Specific examples include: - Forefoot, Midfoot, and Hindfoot Osteotomies - Metatarsals and Metacarpals Corrections and Osteotomies - Stabilization and Fixation of Metatarsal and Metacarpal Fractures - Stabilization and Fixation of Ankle Fractures - Syndesmosis Joint Stabilization - Arthrodesis of Metatarsophalangeal (MTP) and Metacarpophalangeal (MCP) joints - Flatfoot and Cavus Foot Corrections - Charcot Fixation ## Device Story ALPHALOK Plating System provides bone fixation via titanium plates, screws, and washers; features polyaxial locking technology and low-profile design. System includes Met Fx (straight, T, Y, Jones, mini plates) and Recon (fusion, Lapidus, peanut, tab, MTP, Cotton & Evans, utility, ankle fracture plates) components. Used by orthopedic surgeons in clinical settings for bone fracture stabilization and osteotomy fixation. Implants are titanium (Ti-6Al-4V); instruments are stainless steel. Surgeon uses manual instrumentation (drills, drivers, guides) to secure plates to bone fragments. Provides mechanical stability to facilitate bone healing. ## Clinical Evidence No clinical data. Evidence consists of bench testing: static four-point bend testing (ASTM F382-17), torsional properties testing (ASTM F543-17), axial pullout calculations (per FDA guidance), and driving torque testing (ASTM F543-17). Cleaning and sterilization validations performed per ANSI/AAMI/ISO 17665-1. ## Technological Characteristics Implant material: Titanium alloy (Ti-6Al-4V, ASTM F136). Instrument material: Stainless steel. Design: Polyaxial locking plates, screws, and washers. Mechanical testing standards: ASTM F382-17 (bend), ASTM F543-17 (torsion/torque). Sterilization: Validated per ANSI/AAMI/ISO 17665-1. ## Regulatory Identification Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system. ## Predicate Devices - Vilex ALPHALOK™ Plating System ([K212348](/device/K212348.md)) - Paragon28 Baby Gorilla/Gorilla Plating System ([K190365](/device/K190365.md)) - Wright Medical Ortholoc 3Di Plating System ([K163044](/device/K163044.md)) - OrthoPro TC Plating System ([K094037](/device/K094037.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
