A 4-year-old boy sustained an accidental self-inflicted gunshot wound to the left forearm. Radiographs revealed a comminuted mid-diaphyseal ballistic radius fracture with a critical-sized bone defect. The fracture was treated with the placement of a flexible intramedullary nail and antibiotic cement spacer, followed by second-stage bone grafting and open reduction and internal fixation of the radius 6 weeks later. Four months after the second-stage procedure, the radial defect healed appropriately without complications.
In this case of a pediatric comminuted mid-diaphyseal radius fracture with bone loss, the induced membrane technique resulted in healing across a critical-sized bone defect.
一名 4 岁男孩的左前臂意外遭受自伤性枪击伤。放射影像显示一处粉碎性骨干中段弹道半径骨折，伴有临界尺寸的骨缺损。骨折采用柔性髓内钉和抗生素骨水泥间隔器固定，6 周后行二期骨移植和桡骨切开复位内固定。二期手术后 4 个月，桡骨缺损适当愈合，无并发症。
在本例儿童粉碎性骨干中段桡骨骨折伴骨缺损的情况下，诱导膜技术导致临界尺寸骨缺损愈合。
