Examples include: · Fixation of bone fragments, in long bones or small bones fractures · Fracture management in the foot or hand · Arthrodesis in hand, foot or ankle surgery · Mono or Bi-cortical osteotomies in the foot or hand or in long bones · Treatment of inferior tibio fibular diastasis · Hindfoot arthrodesis ## Device Story Bone fixation system; includes compression screws and caps. Screws feature self-drilling distal tip; self-tapping distal threads. Used by surgeons for fracture management; bone reconstruction; arthrodesis; osteotomies. Provides mechanical stabilization of bone fragments. Sold non-sterile; requires sterilization before use. ## Clinical Evidence Bench testing only; testing performed in accordance with ASTM 543-02. ## Technological Characteristics Metallic bone fixation fastener; stainless steel (ASTM F 138, cold worked). Features self-drilling/self-tapping distal end. Available in various lengths/thread lengths. Non-sterile. ## 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 - Newdeal I.CO.S.® Screw ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
