Intended Use

The Synthes MatrixNEURO Cranial Plating System is intended for use in fixation of the cranial bones in procedures such as reconstruction, fracture repair, craniotomies, and osteotomies.

Device Story

System consists of titanium reconstruction meshes and titanium alloy screws for cranial bone fixation. Implants provided in various shapes/sizes for anatomical fit. Meshes feature hourglass cut-outs for intraoperative contourability and single-sided screw recesses. Screws include standard and emergency types with specific thread pitches. Used by surgeons in clinical settings for cranial procedures. Mechanical performance verified via bench testing (cross-sectional area, stiffness, pullout load, torque). System provides stable bone fixation to facilitate healing in reconstruction or trauma cases.

Clinical Evidence

No clinical data. Substantial equivalence determined based on non-clinical bench testing comparing cross-sectional area, section modulus, peak load, stiffness, insertion/failure torque, and pullout load against predicate devices.

Technological Characteristics

Materials: Titanium (meshes) and titanium alloy (screws). Principle: Metallic bone fixation implants. Form factor: Contoured meshes with hourglass cut-outs and various screw sizes. Sterilization: Provided sterile. Connectivity: None. Software: None.

Indications for Use

Indicated for fixation of cranial bones in patients undergoing reconstruction, fracture repair, craniotomies, and osteotomies.

Regulatory Classification

Identification

A preformed alterable cranioplasty plate is a device that is implanted into a patient to repair a skull defect. It is constructed of a material, e.g., tantalum, that can be altered or reshaped at the time of surgery without changing the chemical behavior of the material.

#### 510(k) Summary (continued)

#### Comparison to Predicate Devices

#### Indications

The predicate devices are indicated for use in a range of anatomic areas (midface, craniofacial skeleton, maxilla, chin) for a variety of surgical applications (craniofacial surgery, reconstructive procedures, selective orthognathic surgery). The Indications for Use statement of the Synthes MatrixNEURO Cranial Plating System falls within the scope of the broader 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.

#### Technological Similarities (Reconstruction Meshes)

- Same principles of operation metallic implants for the fixation of bone. ●
- Similar sizes and shapes compared to the predicates. .
- Same thickness as the Low Profile Contourable Mesh Plate predicate. .
- Same mesh pattern hourglass cut-outs to allow for similar intraoperative contourability. .
- Same screw recess inner diameter as the predicate Synthes Neuro Plate and Screw System, . and therefore compatible with same screws.
- Same strength-based color coding gradient as the predicate Synthes Neuro Plate and Screw . System mesh.
- Same material as the predicates. .
- The proposed reconstruction meshes are offered sterile. The meshes in the predicate Synthes . Neuro Plate and Screw System are offered sterile and non-sterile.

#### Technological Differences (Reconstruction Meshes)

- The bar width and screw recess outer diameter dimensions of the proposed devices are . greater than those of the predicates.
- The proposed Reconstruction Meshes feature a single-sided screw recess; the predicate . devices feature double-sided screw recesses.

#### Technological Similarities (Screws)

- Same principles of operation metallic implants for the fixation of bone. .
- . Similar lengths as the predicates.
- Same solid shaft as the Low Profile Neuro System predicates. .
- . Similar drive recess to the Low Profile Neuro System predicates.
- Similar type of tips on standard screw as the predicates. .
- Same type of tip on emergency screw as the predicates. .
- Same thread pitch as the Synthes Neuro Plate and Screw System predicate. .
- Same material as the predicates. .
- The proposed screws are offered sterile. The screws in the predicate Synthes . Neuro Plate and Screw System are offered sterile and non-sterile.

#### Technological Differences (Screws)

- The major diameter of the standard screw is slightly smaller than the Low Profile Neuro . System predicates.

#### Non-clinical performance data

Non-clinical performance data compared the proposed devices to the predicates:

- . cross-sectional area
- section modulus .
- peak load at 2 mm of displacement .
- . stiffness at 2 mm of displacement
- . insertion torque
- failure torque .
- . insertion factor of safety
- pullout load . •

The non-clinical performance data demonstrate that the mechanical performance of the proposed Synthes MatrixNEURO reconstruction meshes and screws is comparable to that of the predicates.

#### Clinical performance data

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

#### Substantial Equivalence

The proposed devices have the same intended use as the predicate devices. The non-clinical performance data included in this submission demonstrate that the proposed devices are as safe, as effective, and perform as well as or better than the predicate devices. It is concluded that the information included in this submission supports substantial equivalence.
