Intended Use

The Arthrex Titanium Opening Wedge Osteotomy System is used in conjunction with titanium bone screws to provide fixation following Proximal Tibial or Distal Femoral opening wedge osteotomies. The A/P sloped plates of the Arthrex Titanium Opening Wedge Osteotomy System are used following Proximal Tibial opening wedge osteotomies where tibial slope adjustments are required. Specifically for use in treatment of non-union, malunion, and fractures of proximal tibia and distal femur including simple, comminuted, lateral wedge, depression, medial wedge, bicondylar, combinations of lateral wedge and depression, and fractures with associated shaft fractures. It is intended to be used with adequate post-operative immobilization.

Device Story

System consists of titanium plates and screws for bone fixation; used in proximal tibial or distal femoral opening wedge osteotomies. Plates include A/P sloped, non-sloped tibial, and femoral designs; feature self-contained locking hole design. Screws available in cancellous and cortical designs. Used by orthopedic surgeons in clinical/surgical settings to stabilize bone segments post-osteotomy or fracture. Provides mechanical fixation to support healing; requires post-operative immobilization. Output is physical stabilization of bone.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Titanium plates and screws; self-contained locking hole plate design; cancellous and cortical screw options; metallic bone fixation appliance.

Indications for Use

Indicated for patients requiring fixation following proximal tibial or distal femoral opening wedge osteotomies, including treatment of non-union, malunion, and fractures (simple, comminuted, lateral/medial wedge, depression, bicondylar, and associated shaft fractures). Requires post-operative immobilization.

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.

## DEVICE DESCRIPTION AND INTENDED USE:

The Arthrex Titanium Opening Wedge Osteotomy System is comprised of plates and screws designed in various sizes to address patient needs. The plates are offered in an A/P sloped tibial plate, a non-sloped tibial plate, and a femoral plate design. The primary feature of the plates is a self-contained locking hole design. The screws are available in a cancellous and cortical design.

The Arthrex Titanium Opening Wedge Osteotomy System is used in conjunction with titanium bone screws to provide fixation following Proximal Tibial or Distal Femoral opening wedge osteotomies. The A/P sloped plates of the Arthrex Titanium Opening Wedge Osteotomy System are used following Proximal Tibial opening wedge osteotomies where tibial slope adjustments are required.

## SUBSTANTIAL EQUIVALENCE SUMMARY

The Arthrex Titanium Opening Wedge Osteotomy System is substantially equivalent to the predicate devices where basic features and intended uses are the same. Any differences between the Arthrex Titanium Opening Wedge Osteotomy System and the predicate devices are considered minor and do not raise questions concerning safety and effectiveness. Based on the information submitted, Arthrex, Inc. has determined that the Arthrex Titanium Opening Wedge Osteotomy System is substantially equivalent to the currently marketed predicate devices.
