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.
鹰嘴骨折在儿童中并不常见。患有成骨不全症（OI）的儿童发生鹰嘴骨折的风险增加。本文报告了一名12岁男性1型成骨不全症患者，其双侧鹰嘴干骺端撕脱骨折不同步发生。他因跌倒导致右侧鹰嘴撕脱骨折，接受了切开复位内固定术，使用两根斯氏针和一根张力带钢丝。他被石膏固定了一个月。三个月后取出斯氏针。首次骨折六个月后，他在踢足球时左侧鹰嘴发生撕脱骨折。他再次接受了切开复位内固定术，使用两根斯氏针和张力带钢丝固定。三个月后取出内固定物。由于他是1型成骨不全症，最终恢复了完全活动能力。除了患有成骨不全症的儿童外，双侧鹰嘴不同步撕脱骨折很少见。在本病例中，张力带钢丝固定获得了良好的功能恢复。
