Intended Use

The Guided Growth 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 consists of stainless steel bone plates (eight-Plate/quad-Plate) for pediatric epiphysiodesis. Plates feature contoured waist, low profile, and center hole for temporary guide pin placement. Attached to external bone surface over growth plate using two or four non-locking screws; screws swivel/diverge as bone grows. Device acts as flexible hinge to redirect growth angle, gradually straightening limb. Used in clinical setting by surgeons; patient allowed immediate mobility/weight-bearing post-implantation. Benefits include gradual correction of congenital/acquired angular deformities without invasive osteotomy.

Clinical Evidence

Bench testing only. Mechanical and functional testing, including tensile strength and stiffness calculations, demonstrated the system meets or exceeds requirements and performs equivalent to predicate devices.

Technological Characteristics

Implant-quality stainless steel (316L) conforming to ASTM F-138. Available in 12mm/16mm (eight-Plate) and 16mm/22mm (quad-Plate) sizes. Fixation via two or four cannulated/solid bone screws. Non-locking screw interface allows divergence. Supplied non-sterile; requires sterilization prior to use.

Indications for Use

Indicated for growing children with angular deformities of long bones, including knee (femur/tibia), ankle, elbow (humerus), and wrist (radius). Contraindicated if physis (growth plates) are fused.

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.

Predicate Devices

• Growth Guidance Plate (eight-Plate) (K031439)
• Guided Growth System (quad-Plate) (K093442)

| Device Trade Name: | Guided Growth System - stainless steel eight-Plate/quad-Plate |
| Common Name: | bone plate |
| Classification Name: | Single/multiple component metallic bone fixation appliances and<br>accessories. (21 CFR Parts 888.3030 |

| Legally Marketed<br>Predicate Devices: | Growth Guidance Plate (eight-Plate) K031439/ 11-20-03<br>Guided Growth System (quad-Plate) K093442/ 06-10-10 |
| Device Description: | The Guided Growth System is designed for the gradual correction of<br>pediatric deformities in both the upper and lower extremities. The device<br>can be used for correction of congenital and acquired deformities<br>provided that the physis (growth plates) are not fused. The plates feature<br>a contoured waist and low profile for pediatric usage. There is a center<br>hole in the plate for a temporary guide pin to be implanted to ensure<br>accurate application of the plate. The plates are attached to the external<br>surface of the bone over the growth plate by two or four screws. These<br>screws are not locked to the plate, but rather are allowed to swivel and<br>diverge in their position as bone growth occurs. The implant acts like a<br>flexible hinge, permitting growth at the growth plate to gradually straighten<br>the limb. Immediately after implantation, the patient is allowed mobility<br>and weight bearing. The plates and screws are made from implant quality<br>stainless steel conforming to ASTM F-138. |

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).

#### Biomechanical Testing:

In order to demonstrate that the Stainless steel Guided Growth System has the mechanical properties necessary to perform its intended use and to perform as well as the predicate device, Orthofix conducted mechanical and functional testing of the system. This testing includes tensile strength testing and stiffness calculations. The results of the testing demonstrated the Stainless Steel Guided Growth System to meet or exceed all testing requirements and to perform as well as the predicate device.

#### Technological Characteristics:

The Stainless Steel Guided Growth System is considered to be substantially equivalent in design, intended use and material to the predicate device. However, there are certain design differences, but these do not raise new questions regarding safety and effectiveness.

| Features | Guided Growth System - Stainless Steel |

| Plate/Screw Material | Implant quality stainless steel (316L) |
| Available Plate<br>Sizes | eight-Plate: 12mm; 16mm<br>quad-Plate: 16mm; 22mm |
| Plate Geometry | Contoured waist and low profile for pediatric usage. Center hole for a temporary<br>guide pin to ensure accurate application of the plate. |
| Fixation Method,<br>Screw Holes | Plates are attached to the external surface of the bone over the growth plate by<br>bone screws two (eight-Plate) or four (quad-Plate) |
| Screw Type | Cannulated or Solid |
| Screw Length | 16mm - cannulated<br>24mm and 32mm - cannulated and solid |

Sterilization:

The stainless steel Guided Growth System components are supplied NON-STERILE and require sterilization prior to use.

Substantial Equivalence:

Substantial equivalence is based upon design, dimension, material characterization, and biomechanical testing of the device in comparison to the predicates. The stainless steel Guided Growth System is substantially equivalent in design and function to the Growth Guidance Plate - eight-Plate (K031493 / 11/20/03) and the Guided Growth System -- quad-Plate (K093442 / 06/10/10)
