【摘要】 目的:为了观察儿童双骨肢体单骨骨折后的过度生长。方法:对前臂单骨骨折179例(不包括孟氏骨折、盖氏骨折及骨骺损伤),小腿单骨骨折123例(不包括骨骺损伤),进行了5～6年的随访,平均7.5年。对比测量了双侧 X 线片中的尺、桡骨长度、胫腓骨长度、桡尺角、桡骨内倾角、桡骨头线、肱骨小头的位置以及踝关节正位片,并对腕、肘关节、踝关节活动进行了对比。结果:前臂有4例,小腿有7例较对侧长2～4mm。前臂、腕、肘关节及踝关节活动无异常。结论:前臂是双骨均衡支撑肢体,小腿虽以胫骨负重为主,但单骨骨折后另一骨同样可起支撑作用,因此均不会出现明显的过度生长。更多还原

【Abstract】 Objective:To observe the overgrowth after the fracture of a single bone in double bone extremities in children.Methods:179 cases of forearm fracture and 123 of lower leg fracture (excluding Monteggia fracture,Galeazzi fracture or physeal injuries)were reviewed.The time of follow-up was 5～8 years(mean 7.5 years).Comparative assessments of bilateral extremities on X-ray examination included length of ulna and radius,radioulnar angle,anteversion of the radius, radiocapitular line,position of the capitellium,length of the tibia and fibula,and anteroposterior project of the ankle.Ranges of motion of the wrist,elbow,forearm and ankle were examined. Results:Overgrowth of affected bones with 2～4 mm in length were found only in 4 cases of fore- arm fracture and in 7 cases of lower leg fracture.Conclusions:In most cases of fracture of single bone on double bone extremities,overgrowth of affected bone has been rarely observed.更多还原
