Surgical outcome of both bone de-rotation osteotomy in congenital radioulnar synostosis: A case report and literature review

Abstract
Radioulnar synostosis is found as a congenital deformity in children or as a post-traumatic deformity in adolescents and adults. Congenital variety is more commonly located in the proximal part of the radius and ulna and restricts the range of motion of the forearm leading to some functional disabilities in the child such as using daily objects and carrying out basic hand to mouth activities like eating. The pronation deformity occurring as a result of this entity can be effectively dealt with single stage both bone forearm de-rotation osteotomy done at different levels in radius and ulna. We report our experience using this procedure in a 4-year old child with unilateral proximal congenital radioulnar synostosis in the non-dominant side. This procedure is relatively simple and we were able to achieve a good functional outcome at one year of follow-up with no associated complications.
