Abstract
We respect and appreciate the readers’ letter to the editor regarding our study. They make valid points. With that being said providing hip stability for these children was not a goal of this procedure nor was there any attempt to reduce the endoprosthesis into the acetabulum. The endoprosthesis was placed as an interposition material with imbricated capsule with an ultimate goal of providing more painless range of motion and was intended to decrease migration. The endoprosthesis also helped prevent heterotopic ossification, a recognized complication of resection arthroplasty of the hip. In addition, we noted one of our article's limitations was its retrospective nature and use on a non-validated outcome score modeled after that of the one utilized in the article by Wright et al. We feel that we were forth coming with our results albeit mixed and reporting of our outcomes and complications in this fragile population. Again we thank the readers for their comments and hopefully this response clarifies some of their concerns.
