Materials: Titanium alloy (ASTM F136). Design: Straight plates with 11 configurations (2-16 holes), 32-200 mm length. Principle: Locking/non-locking bone fixation. Sterilization: Moist heat (non-sterile) or X-ray beam (sterile). Connectivity: None (mechanical implant).

Indications for Use

Indicated for fixation of fractures, osteotomies, and non-unions of the scapula, olecranon, radius, ulna, foot, distal tibia, and fibula.

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.

### SUBJECT DEVICE DESCRIPTION

The purpose of this submission is to obtain marketing clearance for additional plate designs to expand the range of the Medartis APTUS® Ankle Trauma System 2.8/3.5, previously cleared under K193633. The subject device APTUS 3.5 TriLock Straight Plates are available in eleven (11) designs with 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, or 16 screw holes. The plates have an overall length ranging from 32 mm to 200 mm. The subject device plates include screw holes designed to accommodate appropriately sized bone screws and K-wires presently marketed as part of the APTUS System. The subject device plates are compatible with screws and K-wires previously cleared in K193633, K110908, and K092038.

The subject device plates are manufactured from titanium alloy conforming to ASTM F136, and are provided non-sterile or sterile to the end user.

### PERFORMANCE DATA

Non-clinical testing data submitted, referenced, or relied upon to demonstrate substantial equivalence included: biocompatibility referenced from K193633; moist heat sterilization (to be performed by the end user) referenced from K193633; X-ray beam sterilization, packaging, and sterile barrier shelf life referenced from K193633; and mechanical testing according to ASTM F382. Clinical data were not provided in this submission.

## EQUIVALENCE TO MARKETED DEVICES

The subject device is substantially equivalent in indications and design principles to the primary predicate device, and the additional predicate devices listed above. Provided at the end of this summary are tables comparing the Indications for Use Statements (IFUS) and the technological characteristics of the subject device, the primary predicate device, and the additional predicate devices.

The Indications for Use Statements (IFUS) for the subject device and the predicate devices listed above include language for fixation of fractures, osteotomies, and non-unions of various bones. The IFUS for the predicate devices K110908 and K193639 do not reference non-unions. The IFUS for the subject device and predicate device K193639 include language that includes use in the foot. The IFUS for the additional predicate devices K082807 and K011335 include language referring to fixation of the pelvis that is not relevant to the subject device. The IFUS for K082807 and K011335 also include language referring to use in osteopenic bone; this language is not included in the IFUS for the subject device. Additionally, the IFUS of the subject device does not list specifically adult patients and pediatric patients as in the predicate device K082807. These minor differences among the IFUS do not impact substantial equivalence because all IFUS express equivalent intended use for internal fixation of bones in various anatomic locations.

The primary predicate K193633 is in support of substantial equivalence in terms of similar plate designs; compatible screw designs; identical plate materials; identical materials for the device-specific (Class II) instruments and accessories; the same sterilization, packaging, and shelf life for product provided sterile to the end user; and the same sterilization for devices provided non-sterile to the end user.

{5}------------------------------------------------

The plates from the subject device and the primary predicate device K193633 and the additional predicate device K082807 have the same technological characteristics, have similar design characteristics, and include screw holes to accommodate locking and non-locking screws.

The subject device plates are compatible with Medartis screws previously cleared in K110908, including 3.5 TriLock (locking) and cortical (non-locking) screws. The subject device plates also are compatible with Medartis K-Wires previously cleared in K092038, K193633, and K193639.

K082807 and K011335 are in support of substantial equivalence in terms of similar Indications for Use, comparable plate designs (use with locking and non-locking screws), and a similar range of physical dimensions (overall width, overall length). K011335 is also in support of substantial equivalence in terms of comparative mechanical testing.

All subject device final finished components (plates, device-specific instrument templates, and device-specific accessories) are manufactured in the same facilities using identical materials and identical manufacturing processes as used for the primary predicate device K193633, and therefore, are substantially equivalent to these previously-cleared devices regarding biocompatibility.

The subject device components that are provided sterile to the end user are packaged using the same materials, are sterilized by the same method, and have the same sterile barrier shelf life as the Medartis devices in K193633. The subject device components that are provided non-sterile also are packaged using the same materials, and are to be sterilized by the same methods as the Medartis devices in K193633.

Non-clinical testing data submitted, referenced, or relied upon to demonstrate substantial equivalence included: biocompatibility referenced from K193633; moist heat sterilization (to be performed by the end user) referenced from K193633; X-ray beam sterilization, packaging, and sterile barrier shelf life referenced from K193633; and mechanical testing according to ASTM F382.

# CONCLUSION

The subject device, the primary predicate device, and the additional predicate devices have the same intended use, have similar technological characteristics, and are made of identical or similar materials. The subject device, the primary predicate, and the additional predicate devices encompass the same range of physical dimensions, are packaged in similar materials, and are sterilized using similar methods.

The data included in this submission demonstrate substantial equivalence to the predicate devices listed above.
