The MatrixRIB Fixation System is indicated for use in skeletally mature patients with normal or osteoporotic bone for the fixation, stabilization, and reconstruction of: - fractures, fusions, osteotomies, and/or resections of the ribs and sternum, including spanning gaps and/or defects - Pectus Excavatum, Pectus Carinatum, and other chest wall deformities .

Device Story

MatrixRIB Fixation System provides surgical stabilization of chest wall. System comprises titanium alloy (Ti-6Al-7Nb) locking plates, locking screws, and intramedullary splints. Used by surgeons in clinical settings for rib/sternum reconstruction and deformity repair. Implants are fixated to bone to provide structural support for fractures or defects. Mechanical performance verified via dynamic compression bending, cantilever bending, and screw pull-out testing. System offers various plate sizes and shapes to accommodate anatomical requirements. Benefits include stabilization of chest wall to facilitate healing and structural integrity.

Clinical Evidence

No clinical data. Substantial equivalence determined based on non-clinical performance data including dynamic compression bending, cantilever bending, and screw torque/pull-out strength testing.

Technological Characteristics

Materials: Titanium alloy (Ti-6Al-7Nb). Components: Locking plates, locking screws, intramedullary splints. Principle: Metallic bone fixation. Connectivity: None. Software: None. Sterilization: Not specified.

Indications for Use

Indicated for skeletally mature patients with normal or osteoporotic bone requiring fixation, stabilization, or reconstruction of ribs and sternum (fractures, fusions, osteotomies, resections, chest wall deformities). Contraindicated for sternal fixation in acute cardiac patients, clavicle or spine fixation, and 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.

# 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 is a superset of the indications statements of the predicate devices. The differences in the Indications statement for the proposed device 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 and Synthes Sternal Fixation . System predicates, i.e. metallic plates that can be fixated to bone.
- Similar sizes and shapes compared to the predicates. .
- Proposed 24-hole and 30-hole straight plates have the same thickness and curved . cross-section as the existing MatrixRIB universal plate.
- Proposed plates have the same locking screw hole design as the existing predicate . MatrixRIB plate, and therefore are compatible with the existing MatrixRIB screws.
- Same material as the existing MatrixRIB plates. .

# Technological Differences of the MatrixRIB Plates

- MatrixRIB sternal plates (made from Titanium alloy) are thinner than the Synthes . Sternal Fixation System predicate plates (made from commercially pure Titanium).
- Most plates in the predicate Synthes Sternal Fixation System have an emergency . release pin; no MatrixRIB plates contain an emergency release pin.
- The STRATOS predicate employs rib clips and connecting bars for fixation/repair . which are made from commercially pure Titanium; the MatrixRIB system employs plates and screws for fixation/repair which are made from Titanium alloy.

### Technological Similarities of the MatrixRIB screws

- Same principles of operation metallic implants for the fixation of bone. .
- Similar lengths as the predicates. .
- Same solid shaft as the existing MatrixRIB Fixation System predicate. .
- Same thread pitch as the existing MatrixRIB Fixation System predicate. .
- Same material as the predicates. .

### Technological Differences of the MatrixRIB screws

- The major diameter of the MatrixRIB screw is slightly smaller than the Synthes . Sternal Fixation System predicates.

### Non-clinical performance data

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

- Dynamic compression bending of plates .
- Cantilever bending of plates .
- Torque testing and pull-out strength of screws .

The non-clinical performance data demonstrate that the mechanical performance of the proposed MatrixRIB Fixation Systemis comparable to that of the predicates.

### Clinical performance data

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

### Substantial Equivalence

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

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

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