The Guided Growth System Eight-Plate and Quad-Plate are designed for the gradual correction of pediatric deformities in both the upper and lower extremities. The system 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. The plates are attached to the external surface of the bone over the growth plate by two or four screws depending on the plate selected. 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.
Benefits to Surgeon
Simple outpatient procedure with no cast required
Contoured plate bends for anatomic fit
Central pilot hole for accurate placement over the physis
Diverging screws function like a hinge to gently guide natural growth
Fully threaded cannulated screws designed to resist pull out forces and allow easy removal after treatment
The Guided Growth System Eight-Plate and Quad-Plate 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 growth 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); and radial or ulnar deviation, flexion or extension deformities of the wrist (radius).
The plates should not be used for adult deformities; skeletal maturity precludes further growth
The plates should not be used where the growth plate has closed due to trauma or infection since further growth is precluded
