The Numelock™ II System is intended for use in the temporary stabilization of long bone fractures.

Device Story

Numelock™ II System comprises metallic locking plates and screws for internal fixation of long bone fractures. Plates are pre-contoured to fit periarticular regions of long bones; feature holes for screw fixation. Used by orthopedic surgeons in clinical/OR settings to stabilize fractures. Device provides mechanical support to bone segments during healing process; facilitates temporary stabilization. Surgeon selects appropriate plate configuration based on anatomical site; secures with screws. Benefits include anatomical fit and stable fixation of bone fragments.

Clinical Evidence

Bench testing only. No clinical data provided. Mechanical testing demonstrated comparable mechanical properties to predicate devices.

Technological Characteristics

Metallic bone fixation system consisting of locking plates and screws. Plates are pre-contoured for periarticular regions. Class II device under 21 CFR 888.3030. Product code KTT.

Indications for Use

Indicated for temporary stabilization of long bone fractures in patients requiring internal fixation.

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.

### Description:

The Numelock™ II System consists of a series of locking plates and screws for the internal fixation of long bone fractures. The plates are available in different styles and configurations to fit various anatomical sites. Each plate has holes for screw fixation and is pre-contoured to fit the anatomical profile of the different periarticular regions of long bones.

#### Intended Use:

The Numelock™ II System is intended for use in the temporary stabilization of long bone fractures.

## Substantial Equivalence:

The design and function of the Numelock™ II System is substantially equivalent to that of the predicate devices. Both the subject and predicate systems offer different types of plates in varying configurations and lengths for use with the other accessories such as locking screws, shaft screws, and washers. This system is equivalent to other systems on the market in regards to design, materials, indications and operational principals. Mechanical testing demonstrated comparable mechanical properties to the predicate devices.
