POTENTIAL RISKS: The risk associated with participation for children in this study is no different than the risk of a standard visit to an orthopedic surgeon at Texas Scottish Rite Hospital for Children, including minimal radiation exposure for radiographic evaluation of the feet. For adults in this study, all radiographs are considered investigational. The amount of radiation exposure, in addition to Standard Care, that may be received in this study is small; comparable to the everyday risk of driving 40 miles in an automobile.
