作者将151例儿童前臂远端1/3骨折随机分成两组,分别采用长臂和短臂石膏管型治疗,随访分析骨折移位、成角及偏移、骨折愈合以及功能恢复情况。113例获得随访,平均8个月。结果显示:石膏塑型不佳者易发生骨折移位;两组维持骨折复位效果相当;短臂石膏组休学时间短,日常活动需要帮助 One hundred and fifteen children with distal 1/3 fractures of the forearm were randomly divided into two groups. The patients were treated with long-arm and short-arm plaster casts respectively. Fracture displacement, angulation and migration, fracture healing and functional recovery were analyzed. 113 cases were followed up for an average of 8 months. The results showed that: poor shape plaster is prone to fracture displacement; two groups to maintain the fracture reduction effect is equivalent; short arm gypsum group off time is short, daily activities need help
