Correctie van verkeerd vastgegroeide onderarmbreuk

The fractura antebrachii (a fracture of both radius and ulna) is one of the most common fractures in children. Fractures with too much displacement are repositioned and stabilized with pens and/or a plaster cast to effect fracture healing. In 30% of the children treated with a plaster cast only, secondary displacement of the fracture occurs. If this displacement is not corrected on time, it can cause a malunion. A malunion can result in pain and functional and cosmetic complaints. A malunion is diagnosed with conventional x-rays and can be showed 3-dimensional by a computer tomography (CT).



A malunion after fractura antebrachii can be improved by a correction osteotomy. In this procedure, the radius and the ulna are re-broken (osteotomy) to restore the anatomy. However, given the complexity of this surgical procedure, many (orthopedic) surgeons are reserved to perform a correction osteotomy of the forearm. With this study, we want to plan the correction osteotomy preoperatively with the help of patient-specific templates based on the unaffected arm using computer models. With this technique, we try to reduce the complexity of the surgery and make the surgery more predictable.
