Monteggia fractures can be problematic injuries. The aim of this population-based study is to evaluate the risk of complications according to the Bado types, clinical outcome, and incidence.
72 children (median age 6, range 2-11 years) with 73 Monteggia fractures treated during 2014-2022 were identified from the institutional fracture register. Timing of diagnosis, complications, and method of treatment were registered. Outcomes were assessed at mean 4 years (1-9) follow-up in 68 (94%) children. The census population (< 16 years old) in Helsinki metropolitan area during the study period was assessed.
Bado types I (n = 43) and III (n = 27) comprised all but 3 of the fractures. Diagnosis was made on admission in 57, and with a 1-8-day delay in 16 children. 8 children had sustained an associated nerve injury. 35 children were treated operatively, 7 after failed closed treatment. 4 reoperations were performed, including 3 ulnar osteotomies. The risk of complications (odds ratio [OR] 4.9, 95% confidence interval [CI] 1.7-14) and closed treatment failures (OR 12.3, CI 1.3-118) was higher in Bado type III than in type I injuries. 60 children attended for clinical follow-up, all had congruent radio-humeral joints and full range of elbow and forearm motion. Mean PedsQL was 94 (72-100) and QuickDash 3 (0-13). 8 additional children reported normal elbow functions by phone. The calculated mean annual incidence of Monteggia injuries was 2.9/100,000 children.
Monteggia fractures are rare (2.9/100,000 yearly). Bado type III injuries are associated with a high risk of complications.
孟氏骨折是一种复杂的损伤。本研究旨在基于人群评估根据 Bado 分型、临床结果和发生率的并发症风险。
从机构骨折登记处确定了 2014 年至 2022 年间治疗的 72 名儿童（中位数年龄 6 岁，范围 2-11 岁），共有 73 例孟氏骨折。记录诊断时间、并发症和治疗方法。68 例（94%）儿童在平均 4 年（1-9 年）随访时进行了评估。评估了研究期间赫尔辛基大都市区的人口普查（<16 岁）。
Bado Ⅰ型（n=43）和Ⅲ型（n=27）除 3 例外均包括所有骨折。57 例患儿在入院时即确诊，16 例患儿延迟 1-8 天确诊。8 例患儿合并神经损伤。35 例患儿接受了手术治疗，7 例患儿在闭合治疗失败后接受了手术治疗。4 例患儿进行了再次手术，包括 3 例尺骨切开术。Bado Ⅲ型骨折的并发症风险（比值比[OR]4.9，95%置信区间[CI]1.7-14）和闭合治疗失败风险（OR 12.3，CI 1.3-118）均高于 Bado Ⅰ型骨折。60 名患儿接受了临床随访，所有患儿均有一致的肱桡关节和完整的肘部和前臂活动范围。平均 PedsQL 为 94（72-100），QuickDash 3 为 0-13。另外 8 名患儿通过电话报告了正常的肘部功能。计算得出孟氏骨折的年平均发生率为 2.9/10 万儿童。
孟氏骨折很少见（每年 2.9/10 万）。Bado Ⅲ型骨折并发症风险高。
