title: [Analysis on complications of elastic nail treating children's long bone fractures].
abstract: OBJECTIVE
  To analyze the reasons on complications of treatment with elastic nail in children's long bone fracture.
  
  
  METHODS
  Sixty-six cases (75 parts of long bone fratures) were treated by elastic nail including 49 male and 17 female. The age ranged from 3 to 17 years, mean 7.8 years. There were 35 femur fractures (2 cases were hibateral), 20 tibia and fibula fractures (12 cases were tibia fractures), 8 radial fractures (1 case was ulna fracture) and 3 humerus fractures. The cases included 4 open fractures and 62 closed fractures. All cases were fresh fractures, no multi-segmental fractures. Three cases associated with brain and chest injuries. These cases were treated by open or closed reduction and internal fixaion with elastic nail. A cast or brace had been used after operation for a month. Following-up included the function of the joint,the bottom of the nail and the callus. Complications were timely recorded.
  
  
  RESULTS
  All the patients were followed-up for 12 to 29 months, averaged 17 months. The cases occurrenced compilications including 2 cases of nonunion, 2 of new fracture, 1 of displacment, 4 of joint dysfunction, 3 of irritation of the bottom of the nail and 1 malunion.
  
  
  CONCLUSIONS
  Strict indication, well design,canonical operation is a good way to avoid compliacations. At the same time,early treatment can reduce the sequela.
