1) Because WRIGHTLOCK rods have a smaller diameter than other systems, the rods will seem flexible. However, a fully assembled WRIGHTLOCK construct will create rigidity comparable to a large rod system. The OCS instrumentation helps ensure a maximum correction by allowing the surgeon to plan the strains in the rods. With a large rod system, … Read more
