锁定钢板联合自体髂骨植骨治疗四肢长骨干骨折术后无菌性骨不连的效果观察

目的：研究评价锁定钢板联合自体髂骨植骨治疗四肢长骨干骨折术后无菌性骨不连的临床效果。方法选取2006年1月∽2013年6月因内固定失败而造成四肢长骨干无菌性骨不连患者43例,均采用锁定钢板固定联合自体髂骨植骨进行治疗。结果患者均获得随访,随访时间7∽24个月,平均12.6个月。骨不连均愈合,愈合时间为（5.9＆#177;1.0）个月。3例（6.9%）出现切口表面感染,经治疗后均痊愈；2例（4.7%）切口延迟愈合；1例（2.3%）出现肢体短缩〈2 cm,无一例发生骨折畸形愈合。末次随访时关节活动度较术前显著改善,其中功能优良35例（81.4%）,可7例（16.3.%）,差1例（2.3%）。结论锁定钢板联合自体髂骨植骨治疗四肢长骨干骨折术后无菌性骨不连,具有确切的疗效,锁定钢板联合自体髂骨移植治疗能为骨折提供可靠的内固定稳定性和良好的骨诱导以及骨传导作用,效果良好。

Effect observation on locking plate combining with autologous iliac bone graft in the treatment of aseptic nonunion after surgery of long bone fractures of extremities

Objective To research and evaluate the effect of locking plate combining with autologous iliac bone graft on treating aseptic nonunion after surgery of long bone fractures of extremities. Methods 43 cases of patients with aseptic nonunion on limb long bone caused by bone fixation failure were accepted in our hospital from January 2006 to June 2013.All of patients were treated with locking plate combining with autologous iliac bone graft. Results All patients were followed up.The follow-up time ranged from 7 to 24 months,with an average of 12.6 months.All of nonunion were healed in （5.9＆#177;1.0） months.Cut surface infection occurred in 3 cases （6.9%）,which were cured after treatment.The slow-ly healed wound were 2 cases （4.7%） and limb about 2 cm shortened in 1 case （2.3%）.None of cases suffered from malunion.At the final follow-up,joint activity improved more significantly compared with before surgery,including 35 cases （81.4%） with excellent effect,7 cases （16.3%） moderate,and 1 case （2.3%） poor. Conclusion In the treatment of patients with aseptic nonunion after surgery of long bone fractures of extremities,using locking plate for internal fixation is a curative therapy.Locking plate combining with autologous iliac bone graft can provide reliable fixation stability for fractura,and shows good functions on bone induction and conduction,so it obtains a favorable effect.
