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 biocompatible titanium rhombus-shaped plates and 2.7mm or 3.5mm screws. The system is used by orthopedic surgeons for internal fixation of small bones in the feet, ankles, and toes. Plates feature specific curvatures, bridge widths, and hole configurations designed to allow intersecting screw pairs without contact. The device provides mechanical stabilization to facilitate bone healing during fracture repair, joint fusion, or reconstructive surgery. It is a passive implantable system; no software or active components are involved.

Clinical Evidence

No clinical data provided; substantial equivalence is supported by non-clinical performance analysis and design comparison.

Technological Characteristics

Biocompatible titanium plates; 2.7mm or 3.5mm screw fixation; rhombus/parallelogram geometry; varying curvatures and bridge widths; passive mechanical implant.

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. Redden:

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.

| | (a)(4). Device Description | |

The DARCO® Locking Bone Plate System is designed with rhombus (parallelogram) plates of biocompatible titanium. The plates use either 2.7mm or 3.5mm screws which intersect each other in pairs. The drill holes of the plates are aligned to assure the screws do not touch. The plates vary essentially through different curvatures, material strengths, number of plate holes and through different grades or bridge widths.

### (a)(5). 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.

## (a)(6). Technological Characteristics Comparison

The DARCO® Locking Bone Plate System is substantially equivalent to the predicates. Two additional locking bone plates are being added to the subject DARCO® Locking Bone Plate System: the TOM Plate (Step) and the Rahmanzadeh plate (General). Both of these plates have identical indications, identical material composition and similar design features compared to other plates of the DARCO® System.

## (b)(1). Substantial Equivalence- Non-Clinical Evidence

The DARCO® Locking Bone Plate System is substantially equivalent to the predicates. Analysis has shown that the performance of the subject bone locking plate system is not a worse case construct of the predicate DARCO® Locking Bone Plate family which is equivalent to the original predicate Normed Titanium Osteotomy Plating system design. The safety and effectiveness of the DARCO® Locking Plate System is adequately supported by the testing rationales, substantial equivalence information, and comparison of design characteristics provided within this premarket notification.

#### (b)(2). Substantial Equivalence- Clinical Evidence

N/A

#### (b)(3). Substantial Equivalence- Conclusions

The design characteristics of the subject devices do not raise affect the safety or effectiveness of the system. From the evidence submitted in this 510(k), the subject devices can be expected to perform substantially equivalent to the predicate system.
