Intended Use

The Flower Bone Screw set is intended to be used for the fixation of bone fractures, fusion of joints or bone reconstruction.

Device Story

Flower Bone Screw Set comprises solid, cannulated, and headless compression screws with associated washers; manufactured from titanium alloy (ASTM F136). Used by orthopedic surgeons in clinical/surgical settings for bone fracture fixation, joint fusion, or bone reconstruction. Device provides mechanical stabilization of bone segments. Performance verified via engineering analysis and bench testing to ensure structural integrity for intended orthopedic applications.

Clinical Evidence

Bench testing only. Testing included mechanical strength analysis and adherence to standards: ASTM F136 (material), ISO 7153-1 (instruments), ISO 10993-1/5 (biocompatibility/cytotoxicity), and ISO 11137-1 (sterilization). No clinical data provided.

Technological Characteristics

Materials: Titanium-6 Aluminum-4 Vanadium ELI alloy (ASTM F136). Configurations: Cannulated screws (2.0-7.3mm diameter, 10.0-130.0mm length), solid screws (2.0-4.5mm diameter, 10.0-70.0mm length), headless compression screws (6.5mm diameter, 45.0-130.0mm length). Sterilization: Radiation. Mechanical fixation via threaded/solid metallic fasteners.

Indications for Use

Indicated for fixation of bone fractures, joint fusion, or bone reconstruction in patients requiring orthopedic surgical intervention.

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.

#### Intended Use / Indications for Use

The Flower Bone Screw set is intended to be used for the fixation of bone fractures, fusion of joints or bone reconstruction.

#### Device Description

The Flower Bone Screw Set consists of the following components and accessories: solid, cannulated, and headless compression screws, as well as washers, all made of a titanium alloy compliant with ASTM F136. The device is provided with general purpose instruments.

#### Technological Characteristics

The Flower Bone Screw Set consists of the following components/configurations:

{1}------------------------------------------------

- Cannulated Bone Screws with a diameter range of 2.0-7.3mm and a length range of . 10.0-130.0mm;
- Solid Bone Screws with a diameter range of 2.0-4.5mm and a length range of 10.0-● 70.0mm: and
- . Headless Compression Bone Screws with a 6.5mm diameter and a length range of 45.0-130.0mm.

## Performance Data

The Flower Bone Screw Set was tested (worse case) according to the following standards:

- . ASTM F136, Standard Specification for Wrought Titanium-6 Aluminum-4 Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R56401);
- ISO 7153-1, Surgical instruments Metallic materials Part 1: Stainless steel (ISO . 7153-1:1991, including Amendment 1:1999); German version EN ISO 7153-1:2000;
- . ISO 10993-1, Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process;
- . ISO 10993-5, Biological evaluation of medical devices - Part 5: Tests for in vitro cytotoxicity;
- . ISO 11137-1, Sterilization of health care products - Radiation - Part 1: Requirements for development, validation and routine control of a sterilization process for medical devices. (Sterility)

In addition, an engineering analysis has been performed to demonstrate that the Flower Orthopedics cannulated, solid and headless compression bone screws provide appropriate mechanical strength for the claimed intended use.

In all instances, the Flower Bone Screw Set functioned as intended and test results, as well as an engineering analysis, demonstrate substantial equivalence with the cited predicate devices.

## Substantial Equivalence

The Flower Bone Screw Set is substantially equivalent to the identified predicate devices. The subject devices have intended uses lindications, technological characteristics, and principles of operation as its predicate devices. An engineering analysis was performed to demonstrate that the Flower Orthopedics cannulated, solid and headless compression bone screws provide appropriate mechanical strength for the claimed intended use. Thus. the subject bone screws are substantially equivalent.
