A stereotaxic device has been developed which allows relatively atraumatic re-rodding of the long bones in the limbs of children with osteogenesis imperfecta. This in turn will clearly lead to the possibility of a more efficacious management of the condition through the ability to carry out re-rodding more frequently as the child grows. Although the device is relatively complex, and correspondingly labor-intensive to build, and somewhat demanding in use, in the authors' opinions, the benefits it provides make it a worthwhile initiative.
