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。
OBJECTIVE: To observe the overexpression of single bone fracture in children with double limbs. Methods: A total of 179 cases of unilateral forearm fracture (excluding Monteggia fracture, Gai fracture and epiphyseal injury), 123 cases of single leg fractures (excluding epiphyseal injury) were followed up for 5-6 years with an average of 7.5 years. The radiographs of the ulnar radius, radial length, tibiofibular length, radial protuberance, radial incline, radial headline, the position of the head of the humerus, and ankle anteroposterior radiographs were compared. Ankle movements were compared. Results: There were 4 cases in the forearm and 7 cases in the lower leg were 2 ~ 4 mm longer than the contralateral side. Forearm, wrist, elbow and ankle movements without exception. Conclusion: The forearm is the bracing member of the bones. Although the tibia weighs mainly, the other bones can also play a supportive role after the fracture of a single bone, so there is no obvious overgrowth.
