Intended Use

The Guided Growth System plates are designed for the express and sole purpose of redirecting the angle of growth of long bone(s). This is useful for gradually correcting angular deformities in growing children. Specific conditions/diseases for which the device will be indicated include: valgus, varus or flexion, extension deformities of the knee (femur and/or tibia), valgus, varus or plantar flexion deformities of the ankle, valgus or varus deformities of the elbow (humerus), radial or ulnar deviation, flexion or extension deformities of the wrist (radius).

Device Story

Guided Growth System Quad-Plate is a metallic bone fixation device for pediatric orthopedic use. It consists of a contoured, low-profile titanium alloy plate with a center hole for guide pin placement; attached to the bone surface over the physis using four screws. Screws are not locked, allowing them to swivel and diverge as bone grows; the implant functions as a flexible hinge to redirect growth and gradually straighten limbs. Used in clinical settings by surgeons for congenital or acquired deformities. Post-implantation, patients are permitted immediate mobility and weight-bearing. The device provides a mechanical means to correct angular deformities without fusion of the growth plate.

Clinical Evidence

Bench testing only. Mechanical and functional testing of the Quad-Plate was conducted in accordance with ASTM F564-02 (Standard Specification and Test Method for Metallic Bone Staples) to demonstrate mechanical properties and performance equivalence to the predicate eight-Plate.

Technological Characteristics

Materials: Titanium alloy (Ti6Al4V ELI) per ASTM F136. Design: Contoured, low-profile plate with four fixation points. Principle: Flexible hinge for guided growth. Energy: None (mechanical). Connectivity: None. Sterilization: Non-sterile, requires sterilization prior to use.

Indications for Use

Indicated for growing children with open physes requiring correction of angular deformities in long bones, including valgus, varus, flexion, or extension deformities of the knee, ankle, elbow, or wrist.

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.

The Guided Growth System is designed for the gradual correction of pediatric Device Description: deformities in both the upper and lower extremities. The device can be used for correction of congenital deformities as well as correction of acquired deformities, provided that the physis (growth plates) are not fused. The plates feature a contoured waist and low profile for pediatric usage. There is a center hole in the plate for a temporary guide pin to be implanted to ensure accurate application of the plate. The plates are attached to the external surface of the bone over the growth plate by two or four screws. These screws are not locked to the plate, but rather are allowed to swivel and diverge in their position as bone growth occurs. The implant acts like a flexible hinge, permitting growth at the growth plate to gradually straighten the limb. Immediately after implantation, the patient is allowed mobility and weight bearing.

| Biomechanical<br>Testing: | In order to demonstrate that the Guided Growth System Quad-Plate has the<br>mechanical properties necessary to perform its intended use, and that the Quad<br>Plate performs as well as or better than the predicate device, Orthofix has<br>conducted mechanical and functional testing of the Quad-Plate in accordance<br>with ASTM F564-02 Standard Specification and Test Method for Metallic Bone<br>Staples. The testing was successfully completed demonstrating the Quad Plate<br>performs as well as the Guided Growth System eight-Plate. |
