Intended Use

The Alta® Fully Threaded Cross-Locking 5.0mm Screw is indicated for use in fractures requiring static and dynamic locking applications which include the Intramedullary Rods in the Alta® Femoral and Alta® Tibial /Humeral Rod Systems. Specifically, these screws will be used with the Alta® Femoral Locking IM Rod (K850441 & K822266), the Alta® CFX Reconstruction Rod (K926232, K935295, & K960524), the Alta® Tiblal/Humeral IM Rod (K884500, K890936, and K954554), and the Alta® Retrograde Rod (K972108).

Device Story

Alta Fully Threaded Cross-Locking 5.0mm Screw is an orthopedic fixation component; used for static and dynamic locking of intramedullary rods in femoral, tibial, and humeral fracture repair. Device features continuous threading along shaft and T25 standard drive hex head. Used by surgeons in clinical/OR settings to secure intramedullary rods within bone. Provides mechanical stability to fracture sites, facilitating bone healing. Modification from predicate involves head design change to T25 drive.

Clinical Evidence

No clinical data; bench testing only.

Technological Characteristics

Material: Titanium (Ti6Al-4V ELI) conforming to ASTM F-136. Design: Fully threaded cross-locking screw with T25 standard drive head. Mechanical fixation device.

Indications for Use

Indicated for patients with fractures requiring static or dynamic locking applications using Alta Femoral, Tibial, or Humeral Intramedullary Rod systems.

Regulatory Classification

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.

This Special 510(k) submission is intended to address a design modification to the predicate Osteo System Locking Screw. Osteo is a sister division of Stryker for whom Howmedica Osteonics is the sole US Distributor and the US Designated Agent responsible for filing 510(k)s. Throughout this document, the modified Osteo screw will be referred to as The Alta® Fully Threaded Cross-Locking 5.0mm Screw. The Alta® Fully Threaded Cross-Locking 5.0mm Screw is a cross-locking screw with continuous threading along the entire shaft. The design modification involves changing the hex head design to a T25 standard drive feature. The modified device will be a new screw for use with the Alta System. The modified component, the Alta® Fully Threaded Cross-Locking 5.0mm Screw, is substantially equivalent to the predicate device which was cleared for marketing via the 510(k) process. Alta® Fully Threaded 5.0mm Screws are manufactured from Titanium (Ti6Al-4V ELI) Alloy, which conforms to ASTM F-136. The intended use of the Alta® Fully Threaded Cross-Locking 5.0mm Screw is identical to that of the Osteo System Locking Screw.
