Examples include: - · Fixation of Small Bone Fragments - · Weil osteotomy - · Mono-cortical fixation - · Osteotomies and fractures fixation in the foot and hand ## Device Story The CHARLOTTE™ Snap-Off Screw is a metallic bone fixation fastener used by surgeons for stabilizing bone fractures or reconstruction in the foot and hand. The device features self-drilling and self-tapping distal threads to facilitate insertion into bone. It is a mechanical implant designed to provide rigid fixation of bone fragments. No electronic, software, or algorithmic components are involved. ## Clinical Evidence Bench testing only; no clinical data provided. ## Technological Characteristics Material: ASTM F136 (Ti-6Al-4V ELI) titanium alloy. Features: Self-drilling and self-tapping distal threads. Form factor: Available in one diameter and three lengths. Mechanical testing performed per ASTM 543-02. ## 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 - CHARLOTTE™ Snap-Off Screw ([K043583](/device/K043583.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
