Rothmund-Thomson syndrome (RTS) is a rare autosomal recessive genodermatosis characterized by poikiloderma, short stature, juvenile cataracts, sparse hair, skeletal abnormalities, and a predisposition to osteogenic sarcomas and skin cancers. While numerous skeletal abnormalities have been described in patients with Rothmund-Thomson syndrome, nonunion cases are rarely reported in the literature. In this study, we present the case of a patient with RTS who sustained a combined ulna and radius fracture in the proximal forearm after a simple fall. The patient was followed for four months with titanium elastic nails, but despite union of the radius, nonunion of the ulna was observed. A second trauma later resulted in re-displacement of the old fracture line of the ulna. The patient subsequently underwent stable fixation with plate and screw fixation, received additional medical treatment, and union was achieved. With our report, we hope to increase practitioner awareness that delayed bone healing may be a possibility in RTS patients and to encourage consideration of routine imaging and calcium and vitamin D supplementation.
