From Oct. 1994 to Dec. 1996, 15 nonunions of pediatric middle and distal shaft of the femur due to previous osteomyelitis and pathologic fracture and/or failed internal fixation were treated with semicircular dynamic locked intramedullary nail (SDLIN). SDLIN was composed of a lateral and a medial nail, both of them were inserted into the medullary canal 1.5 cm above the epiphyseal line, and the tails were connected together by a bolt. All the 15 cases used iliac bone autograft for the defect. Follow-uped for an average of 16.3 months, all of them were healed in an average of 4.8 months, and excellent and good results were obtained in 86.7%. The results suggest that the SDLIN is effective and convenient for the fixation of the refractory nonunion of pediatric middle and distal shaft of the Femur.
1994年10月至1996年12月，采用半圆形动力锁定髓内钉（SDLIN）治疗15例因既往骨髓炎、病理性骨折和/或内固定失败导致的小儿股骨干中下段骨不连。SDLIN由外侧钉和内侧钉组成，两者均插入骨骺线以上1.5 cm的髓腔内，尾部通过螺栓连接在一起。15例均采用自体髂骨植骨修复骨缺损。平均随访16.3个月，平均4.8个月全部愈合，优良率为86.7%。结果表明，SDLIN治疗小儿股骨干中下段难治性骨不连有效且操作简便。
