Device Story

SIGNEX system consists of metallic bone plates and screws for internal fixation of fractures, fusions, osteotomies, and reconstructions. Plates are available in various anatomical shapes (straight, Y, T, square) and screws are provided in cannulated and non-cannulated configurations. Devices are supplied non-sterile and intended for single-use; must be sterilized by the user prior to surgery. Used by orthopedic surgeons in clinical settings to stabilize bone segments, facilitating healing and structural reconstruction. Output is mechanical fixation of bone fragments. Benefits include restoration of skeletal alignment and stability.

Clinical Evidence

Bench testing only. Biocompatibility testing performed per ISO 10993 (cytotoxicity, sensitization, irritation, systemic toxicity, genotoxicity, pyrogen, implantation). Mechanical testing performed per ASTM standards (torsion, axial pullout, driving torque, 4-point bending). No clinical data provided.

Technological Characteristics

Materials: Pure Titanium (ASTM F67) and Ti-6Al-4V ELI Titanium alloy (ASTM F136). Surface treatment: Anodizing. Mechanical principle: Metallic bone fixation via plates and screws. Dimensions: Plates (6.90-280.00 mm length, 0.60-5.00 mm thickness); Screws (5.00-140.00 mm length, 1.30-5.00 mm diameter). Non-sterile, single-use.

Indications for Use

Indicated for fixation of fractures, fusions, osteotomies, non-unions, malunions, and reconstructions in upper extremities (humerus, olecranon, radius, ulna, metacarpals, phalanges), lower extremities (femur, tibia, fibula, tarsals, metatarsals, phalanges), and clavicle.

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.

### Discussion

Since there is the difference in size of plate and the predicate device, the reference devices were compared for supporting the difference of the subjective device.

Screw length was not within the range of receince device. However, its safety and effectiveness were demonstrated as a result of performance tests according to FDA guidance and ASTM F-4. Since the acceptance criteria of FDA guidance, and the comparison test result was equal to or geater than the predicate device (K092609), the difference of screw length is not a significant difference that raise questions of safety and effectiveness.

# 9. Conclusions

As a result of the substantial equivalence comparitily equivalent with the predicate device except for the product size. Therefore, the reference devices were added to support the difference of product size of subject device is covered in the range of the predicate device and the reference devices, except of screw length. However, it has been length does not rase questions of safety and effectiveness.

In conclusion, the subject device, SIGNEX, is determined to the predicate device (K12324) and the reference devices (K14489, K192609).
