阻挡钉结合植骨治疗胫骨骨折髓内钉术后骨不连

目的探讨阻挡钉结合植骨技术治疗胫骨骨折髓内钉术后骨不连的疗效。方法对18例胫骨骨折髓内钉治疗术后并发骨不连的患者（其中男11例,女7例）,采用阻挡钉技术稳定骨断端以及植骨的方法,观察其疗效。结果术后随访13~19个月（平均15.8个月）,所有患者均获得骨性愈合,愈合率100%,愈合时间7.7~13.8个月（平均9.8个月）。结论阻挡钉结合植骨技术是一种治疗胫骨骨折髓内钉术后骨不连的有效方法。

Blocking screws combined with bone grafting in the treatmentof nonunion of fractured tibial following intramedullary nailing

Objective To investigate the therapeutic effects of the combined technique of blocking screws combined with bone grafting on tibial nonunion following intramedullary nailing.Methods 18 patients（11 males and 7 females） with nonunion of tibial fracture following intramedullary nailing underwent stabilization of the bone segments with blocking screws and bone grafting technique and the therapeutic effects were observed.Results Follow-ups ranging 13-19 months（mean=15.8） showed that all the nonunions healed,with a healing rate of 100% and the period required to achieve union of 7.7~13.8 months（mean=9.8）.Conclusion Blocking screws combined with bone grafting technique is an effective approach in the treatment of nonunion of tibial fracture following intramedullary nailing.
