Intended Use

The DARCO ™ Locking Bone Plate System is intended for use in stabilization of fresh fractures, revision procedures, joint fusion, and reconstruction of small bones of the feet, ankles and toes. The system can be used in both adult and pediatric patients.

Device Story

The DARCO™ Locking Bone Plate System consists of titanium plates and screws for internal bone fixation. Plates feature rhombus (parallelogram) geometries in various widths, lengths, and configurations to accommodate patient anatomy. The system includes 2.7 mm and 3.5 mm diameter locking and non-locking screws. Used by orthopedic surgeons in clinical settings to stabilize bone fragments, facilitate joint fusion, or perform reconstruction. The device provides mechanical support to bone segments, promoting healing and structural alignment. The system is a modification of a previously cleared predicate, specifically involving the 3.5 mm locking screw head design.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by non-clinical bench testing, including pullout strength, insertion, removal, ultimate/yield strength, and screw head locking torque evaluations.

Technological Characteristics

Materials: Titanium. Components: Rhombus-shaped plates and 2.7 mm/3.5 mm diameter locking/non-locking screws. Principle: Internal bone fixation via mechanical stabilization. Connectivity: None (mechanical device).

Indications for Use

Indicated for stabilization of fresh fractures, revision procedures, joint fusion, and reconstruction of small bones of the feet, ankles, and toes in adult and pediatric patients.

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.

Dear Ms. Myles:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
