AmyW Hi there, In 2015, my son Caden had bilateral femoral de-rotational osteotomies with Dr. Mulpuri. We did not have the spica-cast afterwards, so I am not sure if my advice will be relevant, but can answer questions about the after if you have specific after-care questions. We prepared for the surgery the same as we have with any other...ensured we had plenty of distractions and pillows of all shapes and sizes to aide in comfort available.
Sorry for such a later reply and that I don't have a more similar experience to offer more relevant information.
