Device Story

Titanium alloy cannulated bone screws; designed for use over guide pins or wires for fracture fixation; includes optional washers for poor bone quality. Used by orthopedic surgeons in clinical settings for various skeletal fractures and joint reconstructions. Device provides mechanical stabilization of bone fragments; facilitates minimally invasive surgical procedures. Benefits include reduced surgical trauma and effective fixation of small joint bones and ligament avulsions.

Clinical Evidence

No clinical data. Substantial equivalence supported by non-clinical characterization and complaint data.

Technological Characteristics

Titanium alloy cannulated bone screws; available in various diameters, lengths, and thread types. Includes optional washers. Mechanical fixation device; non-powered; non-sterile/sterile (implied by surgical use).

Indications for Use

Indicated for bone fracture and fragment fixation in patients requiring minimally invasive joint reconstruction, including fractures of the humerus, tibia, radius, wrist, ankle, elbow, shoulder, hand, foot, calcaneus, talus, and tarsal region; ligament fixation; and ankle arthrodesis. Optional washers for poor bone quality.

Regulatory Classification

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.

Dear Ms. Lee,

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). 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.
