Three boys with mild osteogenesis imperfecta (OI) who sustained eight apophyseal avulsion fractures of the olecranon were compared with four normal boys with a unilateral apophyseal fracture. The children with OI were younger (11 years 7 months) than the normal children (14 years 3 months). All fractures were treated with tension band wiring (TBW). The contralateral elbow fractured 1 to 12 months later in the children with OI. Refractures occurred in two elbows, 6 to 16 months after the initial fracture and after TBW removal. One refracture presented late as a nonunion and was treated with bone grafting and plate fixation. None of the normal children experienced refracture after TBW removal. Good functional results and range of movement were achieved. Surgical treatment is recommended for all displaced fractures of the olecranon apophysis. There is a high risk of bilateral injury and a risk of refracture following removal of TBW in children with OI.
对3名患有轻度成骨不全（OI）且发生了8例尺骨鹰嘴骨骺撕脱骨折的男孩与4名单侧骨骺骨折的正常男孩进行了比较。患有OI的儿童（11岁7个月）比正常儿童（14岁3个月）年龄更小。所有骨折均采用张力带钢丝固定（TBW）治疗。患有OI的儿童对侧肘部在1至12个月后发生骨折。在初次骨折和TBW取出后6至16个月，两个肘部发生了再骨折。1例再骨折表现为延迟性骨不连，采用植骨和钢板固定治疗。正常儿童在TBW取出后均未发生再骨折。获得了良好的功能结果和活动范围。对于所有尺骨鹰嘴骨骺移位骨折，建议进行手术治疗。患有OI的儿童存在双侧损伤的高风险以及TBW取出后再骨折的风险。
