Intended Use

The MODUS® Titanium Osteosynthesis System is intended for osteotomies and fractures involving any part of the craniofacial skeleton and requiring positional and functional stability. Indications include fixation in the nasoethmoidal, intraorbital, and frontal sinus areas; fixation of comminuted fractures of maxillo-facial and craniofacial areas; tumor surgery for defect bridging; reconstruction of bony structures by means of mesh materials; coverings for burr holes in the skull; trauma of nasal bones; surgical correction of dentofacial deformations; and reconstruction after tumor surgery.

Device Story

MODUS® Titanium Osteosynthesis System consists of titanium implant plates and screws used for internal fixation of craniofacial fractures, osteotomies, and bone reconstruction. System provides positional and functional stability to bone segments. Operated by surgeons in clinical/hospital settings. Modifications involve new plate shapes designed for improved strength and anatomical adaptation. System uses previously cleared titanium screws. Output is physical stabilization of bone; healthcare providers use device to restore skeletal integrity and function. Benefits include improved clinical effectiveness through enhanced anatomical fit.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Materials: CP titanium meeting ASTM F 67 and ISO 5832-2. Components: Implant plates and screws. Form factor: Various shapes for craniofacial anatomy. Non-sterile. No software or electronic components.

Indications for Use

Indicated for patients requiring internal fixation of fractures, correction osteotomies, bridging of load-bearing bone segments, or distraction in the craniofacial skeleton, including nasoethmoidal, intraorbital, frontal sinus, and maxillo-facial areas; also for tumor defect bridging, skull burr hole coverage, nasal bone trauma, and dentofacial deformity correction.

Regulatory Classification

Identification

A bone plate is a metal device intended to stabilize fractured bone structures in the oral cavity. The bone segments are attached to the plate with screws to prevent movement of the segments.

Predicate Devices

• CMF-Titanium Cranio-Maxillo-Facial Fracture Fixation System (K946165)
• MODUS® 2.5 Mandibular Trauma Set (K992683)

### ESTABLISHMENT REGISTRATION NUMBER

Medartis, Inc. has submitted an Establishment Registration to FDA. The Establishment Registration number has not yet been assigned.

#### DEVICE CLASSIFICATION

FDA has classified bone plates as Class II devices (21 CFR 872.4760). The product code for bone plates is JEY. This device classification is reviewed by the Dental Products Panel.

### CONFORMANCE WITH PERFORMANCE STANDARDS

No performance standards applicable to bone plates have been established by FDA. However, the CP titanium used to manufacture the MODUS® Titanium Osteosynthesis System meets the chemical and mechanical requirements of ASTM F 67 Standard Specification for Unalloyed Titanium for Surgical Implant Applications and ISO 5832-2 Implants for surgery - Metallic materials - Part 2: Unalloyed titanium.

### PREDICATE DEVICE INFORMATION

The predicate devices for this modification are from the MODUS® Titanium Osteosynthesis System. Medartis AG, the parent organization of Medartis, Inc. has acquired the rights to the Elekta Instruments, Inc. CMF-Titanium Cranio-Maxillo-Facial Fracture Fixation System, cleared by FDA on May 23, 1995 under K946165, and has marketed it as the MODUS® Titanium Osteosynthesis System. The MODUS System was expanded with the addition of the MODUS® 2.5 Mandibular Trauma Set, cleared by FDA

510(k) Summary - Modifications to the MODUS® Titanium Osteosynthesis System - Page 2

on November 24, 1999 under K992683. The MODUS System has now been modified by the addition of new shapes, which are the subject of this Special 510(k).

# PACKAGING/LABELING/PRODUCT INFORMATION

The MODUS® Titanium Osteosynthesis System will be packaged and sold non-sterile. The device is not represented to be "pyrogen free." All catalogues will be amended to include the modified devices, consistent with the information shown for existing devices.

### INTENDED USE

The MODUS® Titanium Osteosynthesis System is intended for osteotomies and fractures involving any part of the craniofacial skeleton and requiring positional and functional stability. Indications include fixation in the nasoethmoidal, intraorbital, and frontal sinus areas; fixation of comminuted fractures of maxillo-facial and craniofacial areas; tumor surgery for defect bridging; reconstruction of bony structures by means of mesh materials; coverings for burr holes in the skull; trauma of nasal bones; surgical correction of dentofacial deformations; and reconstruction after tumor surgery.

### DEVICE DESCRIPTION

The MODUS® Titanium Osteosynthesis System consists of implant plates, implant screws and instruments and is used for the internal fixation of fractures, correction osteotomies, the bridging of load bearing bone segments and distraction in the craniofacial skeleton. This submission includes modifications to the MODUS system plates that enhance clinical effectiveness due to improved strength or anatomical adaptation. All modifications discussed in this submission use previously cleared Medartis titanium screws.

### EQUIVALENCE TO MARKETED PRODUCT

The modified implants included in this submission have the following similarities to the predicate:

- · have the same intended use,
- · use the same operating principle,
- · incorporate the same basic design, and
- · incorporate the same materials.

In summary, the modified implants described in this submission are, in our opinion, substantially equivalent to the predicate devices.
