Clinical description

The Hinge Pediatric Plating System is a hinged plate developed by Pega Medical (an OrthoPediatrics group company) for the correction of angular deformities in children and adolescents through the principle of guided growth. The system comprises a plate and two screws and is fixed on either side of the growth plate (physis), controlling axial growth and gradually correcting the deformity.

Unlike deformable plates without a mechanical hinge — which generate stresses and pull-out forces on the screws — the Hinge Plate places a true hinge exactly at the growth plate. The unconstrained angular correction around this pivot point reduces structural stresses on the device and the risk of implant failure.

The plate continuously conforms to the bone surface, without stress, allowing a gentle and minimally invasive correction while avoiding osteotomies. The system was developed in collaboration with Dr. Daniel Green (Hospital for Special Surgery, New York).

Indications

Temporary correction of angular deformities of the long bones through guided growth.
Knee (femur and tibia): varus, valgus, flexion, or extension deformities.
Elbow (humerus): valgus or varus deformities.
Wrist (radius and ulna): flexion or extension deformities.
Ankle: varus, valgus, or plantar flexion deformities.

Key features

True hinge at the physis

Ideal placement of a true hinge at the growth plate allows guided management of the deformity.

Unconstrained correction

Free angular rotation around the pivot point reduces stresses and the risk of implant failure.

Stronger screws

Reinforced screw design, adaptable to different bone morphologies.

Simple, minimally invasive technique

A gentle correction that avoids osteotomies; a precise and simple surgical technique.

Rotational guided growth: a preliminary study of its use in children

Paley D., Shannon C. · Children (MDPI), 2023

The study describes a minimally invasive technique for correcting rotational deformities of the femur and tibia, using separate Hinge Plate halves fixed to the epiphysis and metaphysis and connected with flexible bands (Fibertape). All patients corrected their rotational malalignment, without open surgery.

8 bones in 5 patients (mean age 8.4 years); mean correction of 30° in the femur and 9.5° in the tibia, over ~12 months.
