## Intended Use

Repair of osteotomies and fractures of small bones in the hand and feet

## Device Story

MaxLock Small Bone System consists of titanium fixation plates and screws for orthopedic surgery. Plates feature X-Cross profile, curvature for anatomical fit, and beveled edges to reduce soft tissue wear; holes are counter-sunk for low-profile screw head seating. Plates are contourable intraoperatively to match bone profile. System used by surgeons for internal fixation of small bone fractures, osteotomies, and arthrodesis. Device provides mechanical stabilization of bone segments to facilitate healing.

## Clinical Evidence

Bench testing only. Finite Element Analysis (FEA) was used to confirm performance characteristics and substantial equivalence to predicate devices.

## Technological Characteristics

Materials: Titanium Ti-6Al-4V ELI Alloy (ASTM F-136). Components: 10 fixation plates, 38 screws. Features: X-Cross profile, beveled edges, counter-sunk holes, contourable plates. Energy source: None (mechanical). Connectivity: None. Sterilization: Not specified.

## Regulatory 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.

## Predicate Devices

- DePuy 100 Tubular Plate ([K920738](/device/K920738.md))
- KLS Martin Hand Plating System ([K040598](/device/K040598.md))

MaxLock™ Small Bone System

All plates and screws in the Maxlock System are made from Titanium Ti-6Al-4V ELI Alloy. This material conforms with ASTM F-136 Standard Specification for Wrought Titanium 6AI-4V ELI Alloy for Surgical Implant Applications.

The unique X-Cross Profile and curvature of the plates are intended to better match the patients' anatomy. All edges are beveled to minimize wear on surrounding soft tissue and ligaments. The plates are contourable during surgery, to allow a better fit to the profile of bone. Plate holes are counter-sunk to lower the profile of the screw head and help minimize wear on the surrounding soft tissue and ligaments.

## Performance Data

FEA's confirm that the MaxLock System is substantially equivalent to its' predicate devices, and that it meets specified requirements for its' intended use.
