Smith & Nephew, Inc. Intramedullary Hip Screws are for single use only. ## Device Story Intramedullary Hip Screw is a metallic bone fixation device; used for stabilization of femoral fractures and reconstruction. Device implanted by surgeons in clinical/OR settings; provides mechanical support to bone segments during healing. Operates via internal fixation; designed to withstand in vivo loading. Single-use device; provides structural stability to facilitate bone union and patient mobility. Benefits include fracture stabilization and correction of femoral deformities. ## Clinical Evidence Bench testing only; no clinical data provided. Mechanical test data indicates the device is equivalent to predicate devices and capable of withstanding expected in vivo loading. ## Technological Characteristics Metallic bone fixation appliance; single/multiple component design. Materials and design features are consistent with legally marketed predicate devices for orthopedic fixation. ## 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 - Smith & Nephew's Intramedullary Hip Screw ([K954712](/device/K954712.md)) - Titanium Nail System ([K981529](/device/K981529.md)) - Trauma Internal Fixation System ([K993289](/device/K993289.md)) - Intramedullary Nail System ([K983942](/device/K983942.md)) - TriGen InterTAN ([K040212](/device/K040212.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
