Bilateral Asynchronous Displaced Olecranon Fractures in a Patient With Osteogenesis Imperfecta

Olecranon fractures are uncommon in children. Children with osteogenesis imperfecta (OI) are at an increased risk of olecranon fractures. This is a report of a 12-year-old male patient with known osteogenesis imperfecta type 1 who sustained bilateral asynchronous olecranon metaphyseal avulsion fractures. He sustained a right olecranon avulsion fracture from a fall and underwent open reduction and internal fixation with two Steinman pins and a tension band wire. He was placed in a cast for a month. The Steinman pins were removed at three months. Six months after the first fracture, he sustained a left olecranon avulsion fracture while playing soccer. He underwent open reduction and internal fixation with two Steinman pins and tension band wiring. Hardware was removed at three months. He was returned to full activity due to his type 1 OI. Bilateral asynchronous avulsion fractures of the olecranon are rare, except in children with OI. In the current case, good functional recovery was obtained with tension band wiring.
