Intended Use

SmartScrew® II is generally intended for maintenance of alignment and fixation of fractures, osteotomies, arthrodeses of cancellous bone. Specifically, it is intended for phalangeal fusion and fracture, metacarpal fusion and fracture, carpal fusion and fracture, wrist arthrodesis, Distal metacarpal fractures, olecranon fractures, radial head fractures, humeral condylar fractures, cancellous fractures and osteotomies of the malleolus, ankle fractures, metatarsal osteotomies and correction of hallux valgus. SmartScrew® II is not intended for use in and is contraindicated for: 1) Fractures and osteotomies of cortical bone (except about the hand and foot) and proximal femoral fractures. 2) Situations where patient co-operation cannot be guaranteed (e.g. active or potential infection). 3) Situations which would not be appropriate for fixation with metallic screws. 4) Patients with suspected or known allergy to the implant material.

Device Story

Bioabsorbable, threaded, solid fixation rod; used for bone fracture/osteotomy stabilization. Device features revised head design for smaller diameter and improved insertion properties compared to predicate. Operated by surgeons in clinical settings for orthopedic fixation. Provides mechanical alignment of bone fragments; facilitates healing. Benefits patient through bioabsorbable material, eliminating need for secondary removal surgery.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on design comparison and bench testing of the modified head geometry.

Technological Characteristics

Bioabsorbable, threaded, solid bone fixation fastener. Manufactured via machining. Sterilized using established processes identical to predicate. Dimensions and thread design consistent with predicate. No software or electronic components.

Indications for Use

Indicated for maintenance of alignment and fixation of fractures, osteotomies, and arthrodeses of cancellous bone in the hand, wrist, elbow, ankle, and foot. Contraindicated for cortical bone fractures (except hand/foot), proximal femoral fractures, patients with suspected/known material allergy, cases of active/potential infection, or where patient cooperation is not guaranteed.

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.

#### Predicate Devices:

Linvatec Biomaterials (the previous Bionx Implants Inc). SmartScrew™M (K012001)

The predicate device is the previously cleared Linvatec Biomaterials (the previous Bionx Implants) Ø 2.0mm fully threaded, solid NuGenFX Screw (K012001). Purpose of this special 510(k) premarket notification is introduction of the new revised head design for Ø 2.0mm fully threaded, solid screw model and introduction of new trade name, SmartScrew® II.

Originally the screw head design of Ø 2.0mm fully threaded, solid NuGenFX Screw (K012001) was designed as a cloverleaf head. Further development of head design for smaller outer diameter and easier insertion of Ø 2.0mm screw model continued and finally new head design with outer attachment of screw driver was finalized. The main purposes were smaller size of screw head and improvement of installation properties without scarifying torsion properties of the screw model.

The revision of head design has no effect on intended use, principles of operation, production methods, raw material or sterilization.

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

pge 华2

The Ø 2.0mm fully threaded, solid SmartScrew® II has the following similarities to the cleared model Ø 2.0mm fully threaded, solid NuGenFX Screw (K012001):

- u has the same indicated use
- uses the same operating principle -
- incorporates the same basic design of thread -
- utilizes the same basic dimensions
- is manufactured by machining -
- is packaged and sterilized using the same materials and processes
- has the same shelf life -

In summary, the Ø 2.0mm fully threaded, solid SmartScrew® II is, in our opinion, substantially equivalent to the predicate device.
