Intended Use

The KLS Martin Level One Rib Fixation System is in the stabilization and rigid fixation of rib fractures in the chest wall including reconstructive procedures, trauma, or planned osteotomies in patients 18 years of age or older.

Device Story

The KLS Martin Level One Rib Fixation System provides rigid bone fixation for thoracic rib fractures. The system consists of pre-contoured PEEK plates and titanium locking screws. It is used by surgeons in clinical settings to stabilize rib fractures, reconstruct chest wall defects, or fixate bone following planned osteotomies. The device functions by mechanically securing bone segments to promote healing. The healthcare provider selects appropriate plate sizes and secures them to the ribs using the provided instrumentation and locking screws. The system benefits patients by providing structural stability to the chest wall, facilitating recovery from trauma or surgical intervention.

Clinical Evidence

No clinical data was required. Substantial equivalence was determined based on non-clinical bench testing, including comparative pull-out system testing against the Synthes MatrixRIB Fixation System (K081623), and biological safety risk assessments conducted in compliance with ISO 10993-1:2018.

Technological Characteristics

System comprises PEEK (ASTM F2026) plates (2-3 mm thickness) and Ti-6Al-4V (ASTM F136) 2.3 mm x 7 mm multidirectional locking screws. Mechanical fixation principle. Non-active, implantable device.

Indications for Use

Indicated for stabilization and rigid fixation of rib fractures in the chest wall, including reconstructive procedures, trauma, or planned osteotomies in patients 18 years of age or older.

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.

# Intended Use/Indications for Use

The KLS Martin Level One Rib Fixation System is in the stabilization and rigid fixation of rib fractures in the chest wall including reconstructive procedures, trauma, or planned osteotomies in patients 18 years of age or older.

### Indications for Use Comparison

The subject device differs from the primary predicate, KLS Martin Thoracic Plating System (K153482), in indications for use. The addition of the Transitional Adolescent B patient population to the subject device indications does not constitute a new intended use because no special considerations are being qiven, or required, for the Category B adolescents compared to adults. The anatomical area of use for the subject device is exclusive to the ribs, whereas the primary predicate device is cleared for the chest wall including sternum.

## Technological Comparison

### Similarities to Predicate:

Both the subject and primary predicate devices are intended for stabilization of bone in the thoracic anatomy. The design / shape of the PEEK rib plates is similar to the rib plates evaluated in the subject and primary predicate devices are fixated with titanium screws.

### Differences from Predicate:

The subject device plates are made from PEEK whereas the plates are made from CP Titanium. The subject device is limited for use in the rib, whereas the primary predicate device was cleared for use in the chest wall, including sternum.

#### Reference Devices:

The KLS Martin LSS Plating System (K151983) has been included as a reference docompatibility data for the subject device. The KLS Martin Level One Rib Fixation System includes implants manufactured from the same materials as the reference device, PEEK The PEEK plates and titanium screws are identical composition, undergo identical manufacturing processes, and have the same permanent body contact duration as those cleared in K151983 - KLS Martin LSS Plating System.

The Synthes MatrixRIB Fixation System (K081623) has been included as a reference device to compare mechanical performance against the subject device.

#### Non-Clinical and/or Clinical Tests Summary & Conclusions 21 CFR 807.92(b)

#### Non-Clinical Performance Data:

Comparative head-to-head bench testing was conducted to determine whether the subject device performs equivalent to or better than the primary predicate device in pull-out system testing was compared to the reference device, Synthes MatrixRlB Fixation System (K081623). The testing met all predetermined acceptance criteria and the results demonstrate that the subject device's performance is substantially equivalent to both the primary predicate device and the reference device. Biological safety risk assessments in compliance with ISO 10993-1 :2018 were completed on the subject devices and concluded the devices are biocompatible and appropriate for their intended use.

#### Clinical Performance Data:

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

#### Conclusions:

The KLS Martin Level One Rib Fixation System has the same intended use and similar technological characteristics as the primary predicate device. Technological differences have been addressed through performance data from the predicate and reference devices. According to the comparison based on the requirements of 21 CFR 807.87 and the information provided herein, it is concluded that the information included in this submission supports substantial equivalence.
