摘要: 目的  探究骨搬移术联合对合端植骨内固定术治疗下肢大段骨缺损的效果及对血清碱性成纤维细胞生长因子(basic fibroblast growth factor,bFGF)、血小板衍生生长因子(platelet derived growth factor,PDGF)、血管内皮生长因子(vascular endothelial growth factor,VEGF)、转化生长因子β(transforming growth factor-β,TGF-β)表达的影响。
方法  选取进行手术治疗的下肢大段骨缺损患者50例,采用随机数字表法分为单一组(25例)及联合组(25例)。单一组使用骨搬移术治疗,联合组在单一组基础上加用对合端植骨内固定术治疗。比较2组愈合情况、并发症发生率、对合端接触后即刻与接触后1周血清炎性因子[C反应蛋白(C-reactive protein,CRP)、肿瘤坏死因子α(tumor necrosis factor-α,TNF-α)及核因子κB(nuclear factor kappa-B,NF-κB)]、bFGF、PDGF、VEGF、TGF-β表达情况。
结果  联合组骨愈合指数、骨愈合时间、外固定时间低于或短于单一组,骨愈合优良率显著高于单一组(P<0.05);对合端接触后即刻,2组CRP、TNF-α、NF-κB、bFGF、PDGF、VEGF、TGF-β水平差异无统计学意义(P>0.05);接触后1周,2组血清CRP、〖JP2〗TNF-α、NF-κB水平均低于接触后即刻,联合组bFGF、PDGF、VEGF、TGF-β〖JP〗水平显著高于接触后即刻,联合组血清CRP、TNF-α、NF-κB水平显著低于单一组,bFGF、PDGF、VEGF、TGF-β水平显著高于单一组(P<0.05)。联合组骨对合端不愈合、钉道感染、固定物松动、关节挛缩、下肢力线不良发生率显著低于单一组(P<0.05)。
结论  骨搬移术联合对合端植骨内固定术治疗下肢大段骨缺损能有效缩短骨愈合时间,改善骨愈合情况,降低炎症反应,升高骨再生相关因子,减少并发症发生率,具有临床推广意义。

Abstract: Objective  To explore the effect of bone transfer combined with joint bone grafting and internal fixation in the treatment of large bone defects of the lower extremities and the serum basic fibroblast growth factor(bFGF) and platelet-derived growth factor platelet derived growth factor(PDGF), vascular endothelial growth factor(VEGF), transforming growth factor β(TGF-β) expression. 
Methods  Fifty patients with large-segment bone defects of the lower limbs were selected for surgical treatment, and they were divided into a single group(25 cases) and a combined group(25 cases) using a random number table method. The single group was treated with bone transfer, and the combined group was treated with contralateral bone grafting and internal fixation on the basis of the single group. Comparing the healing status, complication rate, and serum inflammatory factors [C-reactive protein(CRP) and tumor necrosis factor-α(TNF-α) and nuclear factor kappa-B(NF-κB)], bFGF, PDGF, VEGF, TGF-β, immediately after contact with the opposite ends and 1 week after contact between the two groups expression. 
Results  The complication rate of bone healing index, bone healing time, external fixation time, nonunion of bone commissure, and nail infection was significantly lower than that of the single group. The excellent rate of bone healing was significantly higher than that of the single group(P<0.05); Immediately after exposure to the end, the levels of CRP, TNF-α, NF-κB and bFGF, PDGF, VEGF, TGF-β were not significantly different(P>0.05), 1 week after exposure, combined group CRP, the levels of TNF-α and NF-κB were significantly lower than those of the single group, and the levels of bFGF, PDGF, VEGF and TGF-β were significantly higher than those of the single group(P<0.05). 
Conclusion  Bone transfer combined with end-to-end bone grafting for the treatment of large segmental bone defects can effectively shorten the bone healing time, improve the bone healing, reduce the inflammatory response and increase the level of bone regeneration related factors, and reduce the patients. Complications have clinical significance.
