儿童孟氏骨折合并骨间背侧神经损伤１３例，讨论其受伤机制及诊断治疗问题。本组年龄３～１２岁。骨折属伸直型１２例，屈曲型１例。新鲜骨折４例，陈旧性骨折９例。神经受压４例，神经粘连５例，神经瘢痕化２例，神经断裂２例。治疗方法采用手法或手术复位，手法复位骨折脱位４例，神经松解术５例，神经吻合术４例。１０例平均随访２年８个月，９例神经功能恢复正常，１例无效。孟氏骨折合并骨间背侧神经损伤的机制与局部解剖特点有密切关系，是脱位桡骨小头的冲击力、挫伤、压迫、牵拉和粘连等诸因素综合作用所致。强调早期诊断、早期复位可取得满意疗效。晚期病例应积极处理，仍可取得较好效果。
Children Monteggia fracture combined with dorsal nerve injury in 13 cases, to discuss the mechanism of injury and diagnosis and treatment problems. The age of 3 to 12 years old. Fracture is straight type in 12 cases, flexion type in 1 case. 4 cases of fresh fractures, 9 cases of old fractures. Nerve compression in 4 cases, nerve adhesion in 5 cases, 2 cases of nerve scarring, nerve fracture in 2 cases. Treatment methods using surgical or surgical reduction, manual reduction fracture dislocation in 4 cases, 5 cases of neurolysis, nerve anastomosis in 4 cases. Ten patients were followed up for 2 years and 8 months on average. Nine patients returned to normal neurological function and one patient was ineffective. Monteggia fracture combined with interosseous dorsal nerve injury mechanism and local anatomical features are closely related to the dislocation of the radial head impact, contusion, oppression, traction and adhesion caused by a combination of various factors. Emphasize early diagnosis, early reduction can achieve satisfactory results. Advanced cases should be actively treated, still get better results.
