English to Spanish Medical Medical (general) Pediatric Orthotics

Hello, everyone, and thanks in advance for your help with this! I am translating a document for a children's hospital which specializes in helping kids with club foot. A Foot Abduction Orthosis is a type of brace used to correct a club foot and make it more flexible and flat to the floor. The target audience for this document is parents whose baby has recently been fitted with this type of device and it is meant to orient them to its goals and what to expect during baby's adjustment period. It's a very low level document, but this particular term is highly specific and technical and I don't even know how to begin to translate it. Ideas?
