应用单臂多功能外固定器治疗儿童四肢骨折３１例，骨折愈合时间为８～１０周，平均５８天。此法具有以下优点：１．不需切开复位，不损伤软组织及骨膜，减少骨折断端的血供破坏，有利于骨折早期愈合；２．可早期进行关节功能锻炼，缩短了骨折愈合后的康复期，无关节僵硬等并发症；３．对合并严重软组织损伤的开放性骨折或邻近关节的骨折，不影响创面修复和局部换药；４．单臂多功能外固定器小巧轻便，患儿带外固定器期间肢体仍可正常活动。
Application of single arm multifunctional external fixator in the treatment of children with limb fractures in 31 cases, fracture healing time is 8 to 10 weeks, an average of 58 days. This method has the following advantages: 1. Do not need to open reduction, does not damage the soft tissue and periosteum, reduce blood supply fracture fracture, is conducive to early fracture healing; Early functional joint exercise can be shortened healing after fracture healing, no joint stiffness and other complications; 3. For open fractures with severe soft tissue injury or fractures of the adjacent joints, does not affect the wound repair and local dressing; 4. Single-arm multi-function external fixator compact and lightweight, children with external fixators can still be normal activities.
