To report the preliminary results of the treatment of aseptic diaphyseal nonunion of the lower extremities with exchange nailing plus blocking screws.
Between June 2005 and September 2008, twelve patients with diaphyseal nonunion in the lower extremities (femur in five patients and tibia in seven; hypertrophic nonunion in eight patients and atrophic nonunion in four) were treated by reaming, exchanging the original intramedullary nail with a larger one, and using blocking screws, and the therapeutic effect assessed.
All patients were followed up for 1-2 years (average, 1.5 years) to assess union. Bony union was achieved in all patients within 4.7-13.5 months (average, 7.8 months). All patients were pain free without any complications by the last follow-up.
The therapeutic method of exchanging the nail combined with blocking screws is effective for aseptic nonunion of the lower extremity after intramedullary nailing.
报告交锁钉加阻挡螺钉治疗下肢无菌性骨干骨不连的初步结果。
2005 年 6 月至 2008 年 9 月,采用扩髓、更换较大的髓内钉、使用阻挡螺钉的方法治疗下肢骨干骨不连 12 例(5 例股骨,7 例胫骨;8 例肥大性骨不连,4 例萎缩性骨不连),并评估疗效。
所有患者均获随访 1-2 年(平均 1.5 年),评估愈合情况。所有患者均在 4.7-13.5 个月(平均 7.8 个月)内达到骨性愈合。末次随访时,所有患者均无疼痛,无任何并发症。
交锁钉结合阻挡螺钉治疗髓内钉固定后下肢无菌性骨不连是有效的。
