Device Story

MatrixRIB Fixation System comprises metallic plates (straight, I, T-plates), screws, and intramedullary splints for chest wall reconstruction and stabilization. Used by surgeons in clinical settings to fixate rib and sternal bone segments. Plates are secured to bone via locking screws. System provides mechanical stabilization for fractures, fusions, or deformities. Benefits include structural support for chest wall integrity and healing. Device is purely mechanical; no software or electronic components.

Clinical Evidence

No clinical data. Substantial equivalence determined via non-clinical bench testing, including intraoperative contouring dynamic tests and comparative four-point static tests, alongside bacterial endotoxin testing.

Technological Characteristics

Materials: Commercially pure titanium (CP Ti Grade 4) and titanium alloy (Ti-6Al-7Nb). Components: Locking plates (straight, I, T-shapes), locking screws, intramedullary splints. Dimensions: 2.8mm plate thickness. Principle: Metallic bone fixation via screw-plate construct. Sterilization: Not specified.

Indications for Use

Indicated for skeletally mature patients with normal or osteoporotic bone requiring chest wall fixation, stabilization, or reconstruction due to rib/sternum fractures, fusions, osteotomies, resections, or chest wall deformities (Pectus Excavatum/Carinatum). Contraindicated for sternal fixation in acute cardiac patients, clavicle/spine attachment, or patients with active/latent infection, sepsis, or inability to follow postoperative care.

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.

### Device Description 5.5.

The proposed additions to the MatrixRlB Fixation System include sternal plates (straight plates, I-plates and T-plates) for fixation and reconstruction of the chest wall manufactured from commercially pure titanium (CP Ti Grade 4).

The previously cleared devices in the MatrixRlB Fixation System (K133616 and K081623) include locking plates, locking screws, and intramedullary splints for the fixation and stabilization of the chest wall for use in patients with normal or osteoporotic bone quality. These implants are available in multiple sizes and are manufactured from titanium alloy (Ti-6A-7Nb).

#### 5.6. Comparison to Predicate Devices

## Indications

The predicate devices are indicated for use in chest wall of the skeleton (i.e. ribs and sternum) for a variety of surgical applications (rib fixation, chest wall reconstruction, and chest wall deformity repair). The Indications for Use statement of the MatrixRIB Fixation System presented in this submission clearly defines the clinical application for each group of implant

{6}------------------------------------------------

devices within the system. The differences in the Indications statement for the proposed devices in comparison to the predicates do not constitute a new intended use not already addressed by the predicates.

# Technological Similarities of the MatrixRIB Plates

- Same principles of operation as the existing MatrixRIB plates and Synthes Sternal ● Fixation System predicates, i.e. metallic plates that can be fixated to bone using screws.
- The plates have similar shapes compared to the predicates: T, I and straight plates.
- . Similar sizes compared to the predicates; proposed plates are 2.8 mm thick and the Sternal Fixation System predicate plates are 3.0 mm thick.
- . Proposed plates have the same locking screw hole design as the existing predicate MatrixRIB plates, and therefore are compatible with the existing MatrixRIB screws.
- The proposed plates are manufactured from the same material as the Synthes Sternal Fixation System predicate (CP Ti Grade 4).

## Technological Differences of the MatrixRIB Plates

- The new sternal plates are 2.8 mm thick compared to the previously cleared MatrixRIB sternal plates (K133616) which are 2.0 mm thick.
- . Most plates in the predicate Synthes Sternal Fixation System have an emergency release pin; the proposed MatrixRIB plates do not have an emergency release pin.
- The predicate plates can be cut intra-operatively to achieve the desired length where the proposed plates are not intended to be cut.

### Non-clinical performance data 5.7.

Non-clinical testing and analyses comparing the proposed devices to the predicates within this submission include:

- Intraoperative Contouring Dynamic Test Method
- Comparative Four Point Static Test Method

The non-clinical performance data demonstrates that the mechanical performance of the proposed MatrixRIB Fixation System is comparable to that of the predicates.

Bacterial Endotoxin Testing was conducted and met the specified endotoxin limits.

### Clinical performance data 5.8.

Clinical testing was not necessary for the determination of substantial equivalence.

#### Substantial Equivalence 5.9.

The proposed devices have the same intended use as the predicate devices. The mechanical testing included in this submission demonstrates that:

{7}------------------------------------------------

- . Any differences in technological characteristics of the predicates do not raise any new questions of safety and effectiveness.
- . The proposed devices are at least as safe and effective as the predicates.

It is concluded that the information provided in this submission supports substantial equivalence.
