3.5mm Pediatric Eight-plate System | Guided Growth Implants for Hemi-epiphysiodesis & Deformity Correction

Advanced 3.5mm Pediatric Eight-plate for Guided Growth

At OrthoPro, we are dedicated to advancing pediatric orthopedics by providing high-precision implants that improve the quality of life for young patients. Our **3.5mm Pediatric Eight-plate** is a state-of-the-art guided growth system designed to correct angular limb deformities such as bowlegs (genu varum) and knock-knees (genu valgum). By temporarily tethering the physis (growth plate), this system utilizes the patient’s natural bone growth to gradually correct alignment, offering a minimally invasive alternative to traditional osteotomies.

Mechanism of Action: Hemi-epiphysiodesis

The **3.5mm Pediatric Eight-plate** functions on the tension band principle. Unlike rigid locking plates used for fractures, the eight-plate serves as a flexible tether. It is placed across the growth plate and secured with screws. As the bone grows, the plate acts as a hinge, retarding growth on the convex side of the deformity while allowing the concave side to grow normally. This differential growth gradually straightens the limb.

Key to this mechanism is the non-rigid fixation between the screw and the plate. The figure-8 design allows the screws to diverge up to 30 degrees as the physis expands, preventing implant failure and ensuring the growth plate is not permanently fused.

Key Features and Surgical Benefits

• Anatomical Low-Profile Design: Pediatric patients have minimal soft tissue coverage. Our plates feature a contoured, ultra-thin profile with rounded edges to minimize soft tissue irritation and improve patient comfort post-surgery.
• Central Guide Hole: The plate includes a central hole for temporary K-wire fixation, allowing the surgeon to perfectly position the implant over the physis before inserting the screws.
• Screw Divergence Capability: The specialized hole geometry accommodates the natural angular change of the screws during the growth process, reducing the risk of screw backing out or breaking.
• Minimally Invasive: The procedure requires a small incision, resulting in less scarring, reduced pain, and faster recovery times compared to corrective osteotomies.

Material and Manufacturing Excellence

Biocompatibility and strength are non-negotiable in pediatric implants. The **3.5mm Pediatric Eight-plate** is manufactured from premium **Titanium Alloy (Ti-6Al-4V)**. Titanium is chosen for its superior corrosion resistance, MRI compatibility, and modulus of elasticity, which is closer to that of bone than stainless steel. This ensures the implant is safe for long-term implantation during the growth correction period.

Clinical Indications

This system is indicated for pediatric patients with open physis (growth plates) presenting with clinical and radiographic evidence of angular deformities, including:

• Idiopathic Genu Valgum (Knock-knees)
• Idiopathic Genu Varum (Bowlegs)
• Leg Length Discrepancy (LLD)
• Deformities secondary to skeletal dysplasias or metabolic bone disorders.
• Flexion deformities of the knee (fixed flexion contracture).

Technical Specifications

Our guided growth system is compatible with standard instrument sets to facilitate ease of use in the operating room. Below are the general parameters for the 3.5mm system:
